The best 4K gaming monitor for most buyers here is the ASUS TUF VG27UQ1A, which pairs native 3840×2160 resolution with a 160Hz refresh rate and G-SYNC Compatible certification at $269, a rare combination of sharpness and speed at this price. Before we get to the picks, a flag worth raising upfront: two products included in this article’s source data are not actually 4K monitors at all. We’re covering them honestly below rather than pretending otherwise, because buyers deserve to know when a listing doesn’t match the category they searched for.
We evaluated eight monitors marketed or listed alongside 4K gaming searches, ranging from $149.99 to $859, and only six of them are genuine 3840×2160 panels. The other two are 1440p monitors from Samsung’s Odyssey line that likely surfaced here due to shared search terms or retailer category overlap, not because they belong in a 4K comparison. We’re keeping them in this article for transparency and because their prices are relevant to anyone comparing a “cheap 4K” option against a “confirmed 1440p” one, but we will not call them 4K monitors, because they aren’t.

ASUS TUF VG27UQ1A
This is our top pick for a genuine 4K gaming monitor in this comparison. It’s a 27″ panel running native 3840×2160 resolution at up to 160Hz, with ASUS’s Extreme Low Motion Blur sync mode, Nvidia G-SYNC Compatible certification, AMD FreeSync Premium support, and a claimed 95% DCI-P3 color gamut. At 27″, 4K resolution works out to roughly 163 pixels per inch, dramatically sharper than any 1080p or 1440p panel in our broader monitor coverage, sharp enough that individual pixels become essentially invisible at normal desk viewing distance.
160Hz at native 4K is a genuinely demanding target; we’d estimate this panel needs at least an RTX 4080-class GPU to approach that refresh ceiling in modern AAA titles, and an RTX 4070 Ti or similar card would more realistically deliver 60-100 fps at 4K high settings without upscaling. The 95% DCI-P3 gamut claim is one of the stronger color figures across our monitor coverage and matters for buyers doing photo or video work alongside gaming, though as with any unverified gamut claim, treat it as a capability spec rather than a factory-calibration guarantee. HDR support is listed but without a specific DisplayHDR brightness tier attached, so expect a modest rather than dramatic HDR upgrade.
For most buyers who want real 4K without OLED pricing, this is the strongest pick in this roundup, and it fits well alongside a broader best gaming monitor comparison for shoppers still deciding on resolution.
- Pros
- Native 4K at up to 160Hz is a rare combination at this price
- Certified G-SYNC Compatible plus broad FreeSync Premium support
- Strong claimed 95% DCI-P3 gamut for creative work alongside gaming
- Cons
- 160Hz at native 4K requires a high-end GPU to actually reach
- HDR support lacks a specific DisplayHDR brightness certification
- No dual-mode option to trade resolution for even higher refresh
Who it’s for: buyers with a high-end GPU who want genuine 4K sharpness without stepping up to OLED pricing.
Samsung 32″ Odyssey G55C — not actually a 4K monitor
We want to be direct about this one: the Samsung Odyssey G55C is a 32″ QHD monitor with 2560×1440 resolution and a 1000R curve, and it is not a 4K panel. At 32″, its 1440p resolution works out to roughly 92 pixels per inch, notably softer than the true 4K panels in this comparison, which land between 137 and 163 PPI depending on size. If you’re specifically shopping for 4K sharpness, this monitor does not deliver it, full stop, regardless of how it surfaced in search results alongside 4K listings.
What it does offer, on its own terms, is a large, VA-based curved panel with FreeSync Premium support and Samsung’s typically strong contrast performance, at a price roughly $70 below the cheapest genuine 4K option in this list. If your actual priority is a big, immersive, contrast-rich curved screen and you’re flexible on resolution, this is a reasonable buy at $199.99; it’s simply the wrong monitor if 4K resolution itself is the requirement. We cover this panel in more depth, on its own merits, in our dedicated 1440p gaming monitor guide.
We’re including it here purely so buyers comparing prices side by side understand exactly what they’d be giving up in resolution to save roughly 25% versus the cheapest true 4K panel in this roundup.
- Pros
- Large, immersive 1000R curve on a 32″ VA panel
- Meaningfully cheaper than every genuine 4K panel in this comparison
- Strong VA contrast for dark, atmospheric games
- Cons
- Not a 4K monitor; resolution is 2560×1440, about a third of 4K’s pixel count
- 92 PPI is soft compared to the 137-163 PPI of true 4K panels here
- Misleading to compare directly against genuine 4K pricing
Who it’s for: buyers who want a large curved VA panel and are fine trading 4K sharpness for a lower price; not a fit if 4K resolution is a hard requirement.
Samsung 27″ Odyssey G5 (G51F) — not actually a 4K monitor
Same flag as above: this is a 27″ QHD monitor at 2560×1440 resolution, not 4K. It’s the cheapest product in this entire comparison at $149.99, and it’s likely included in 4K-adjacent listings because of overlapping search terms or Amazon category tagging rather than any genuine 4K spec. At 27″, its 1440p resolution comes out to roughly 109 PPI, sharper than the 32″ Samsung above but still well short of the 163 PPI a true 27″ 4K panel like the ASUS TUF VG27UQ1A delivers.
On its own terms, this is a solid entry-level 1440p monitor with VA contrast and FreeSync Premium support, and we recommend it in that context in our dedicated 1440p gaming monitor roundup. But we won’t dress it up as a 4K pick here; if 3840×2160 resolution is what you searched for, this monitor simply does not provide it, and buying it under the impression that it does would be a mistake we’d rather help you avoid than profit from.
Anyone comparing this against the true 4K options in this list should understand they’re comparing a $150 monitor at roughly a third of the pixel count against panels starting near $180 for genuine 4K resolution.
- Pros
- Lowest price in this comparison by a wide margin
- Reasonable 1440p sharpness and VA contrast on its own terms
- FreeSync Premium keeps motion smooth for the resolution it actually offers
- Cons
- Not a 4K monitor; resolution is 2560×1440, not 3840×2160
- 109 PPI is noticeably softer than any true 4K panel in this roundup
- Its presence in 4K search results is a listing or categorization mismatch, not a genuine fit
Who it’s for: budget 1440p buyers only; skip this if 4K resolution is a requirement, not a nice-to-have.
Acer Nitro VG270K V4
Back to genuine 4K territory, the Acer Nitro VG270K V4 is a 27″ panel running native 3840×2160 resolution at up to 160Hz, with a dynamic frame rate feature that Acer lists as supporting up to 320Hz, almost certainly by dropping resolution in a secondary mode rather than running 320Hz at full 4K simultaneously. This dual-personality approach, similar in concept to LG’s dual-mode panel later in this list, lets one monitor serve both visually demanding single-player games at full 4K and faster competitive titles at a reduced resolution and much higher refresh rate.
At $229.99, this is the best-value genuine 4K panel in our comparison, undercutting the ASUS TUF VG27UQ1A by $40 while offering a similar native 160Hz ceiling at full 4K resolution. We’d estimate this panel needs roughly the same high-end GPU tier as the ASUS to hit 160Hz at native 4K, an RTX 4080-class card or better, with more modest GPUs comfortably handling 60-100 fps at 4K high settings instead. Acer doesn’t list a specific HDR certification tier on this model, so treat any HDR marketing language cautiously.
For buyers who want the flexibility of a lower-resolution high-refresh mode without LG’s premium pricing later in this list, this is the pick to shortlist alongside a general 27 inch gaming monitor comparison.
- Pros
- Cheapest native 4K 160Hz panel in this comparison
- Dual-mode flexibility between full 4K and a higher-refresh reduced mode
- Acer’s Nitro gaming line typically includes solid connectivity and VRR support
- Cons
- No specific HDR certification tier listed
- 320Hz mode almost certainly requires dropping well below native 4K resolution
- Requires a high-end GPU to use the native 4K 160Hz mode fully
Who it’s for: buyers who want genuine 4K plus the flexibility of a high-refresh mode without paying LG’s premium.
ASUS ROG PG32UCDP
The clear premium pick in this comparison, the ASUS ROG PG32UCDP is a 32″ native 4K OLED panel running at 240Hz, a specification tier that simply doesn’t exist elsewhere in this roundup. At $859, it costs more than three times the next most expensive monitor here, and that price reflects OLED panel technology, which delivers per-pixel black levels and response times measured in fractions of a millisecond, a fundamentally different tier of picture quality than any LCD panel, VA or IPS, can produce.
At 32″ and native 4K, pixel density lands around 138 PPI, and combined with OLED’s near-instant pixel response, this panel should deliver both exceptional sharpness and motion clarity that LCD-based 4K panels can’t match, even the fast IPS options elsewhere in this list. Running 4K at 240Hz is an extreme GPU demand, realistically requiring an RTX 4090 or equivalent flagship-tier card even with aggressive upscaling like DLSS to sustain frame rates anywhere near that ceiling in modern AAA titles; without that hardware, buyers are paying for headroom rather than a usable feature.
The genuine trade-off with any OLED gaming monitor, covered in more depth in our buying guide below, is burn-in risk from prolonged static content like HUDs, taskbars or paused screens; ASUS includes pixel-shifting and panel-refresh mitigations standard on modern OLED monitors, but the risk isn’t zero, and buyers using this primarily for hours of office work with static UI elements should weigh that against LCD alternatives.
- Pros
- OLED picture quality and response time no LCD panel in this roundup can match
- 240Hz at native 4K is unmatched by any other monitor in this comparison
- 32″ size and 138 PPI density balance sharpness with screen real estate
- Cons
- Costs more than three times the next most expensive panel in this list
- Requires flagship-tier GPU hardware to approach 240Hz at native 4K
- Carries OLED burn-in risk that no LCD panel in this roundup shares
Who it’s for: buyers with the budget and GPU to match, who want the best possible picture quality available in this comparison.
ZZA 32″ 4K Curved
The ZZA is a 32″ curved 4K panel with a 1500R curve, 165Hz refresh rate, built-in speakers, AMD FreeSync support, HDR10 compatibility, and a claimed 120% sRGB gamut, using a VA panel based on the listing’s described contrast and curve characteristics. At $242.99, it’s the second-cheapest genuine 4K monitor in this comparison and the only curved true-4K option here, combining large-screen immersion with actual 4K sharpness at a price below the ASUS TUF VG27UQ1A.
ZZA is a considerably less established brand than Samsung, LG, Acer or ASUS, and we have limited independent track record on this manufacturer’s panel quality, calibration consistency or long-term reliability compared to the more established names in this roundup; that’s a real consideration for a purchase in this price range, not a knock against the spec sheet itself. At 32″ and native 4K, pixel density lands around 138 PPI, and with 165Hz refresh we’d estimate this panel needs an RTX 4080-class GPU to approach that ceiling at native resolution, similar demands to the Acer and ASUS panels above. The 120% sRGB claim suggests a wide-gamut backlight, but without independent verification or a known brand calibration standard, treat it as an unconfirmed capability rather than a guaranteed accuracy figure.
If curved 4K at this price matters more to you than buying from an established display brand, this is worth considering alongside a dedicated curved gaming monitor comparison, with the caveat that we can’t vouch for ZZA’s build quality the way we can for the more established brands in this list.
- Pros
- Only genuine curved 4K panel in this comparison
- Cheapest curved 4K option, undercutting the ASUS TUF VG27UQ1A
- 165Hz refresh at native 4K resolution is a strong spec on paper
- Cons
- Considerably less established brand than the other manufacturers in this list
- Gamut and HDR claims are harder to verify without an established calibration track record
- Requires a high-end GPU to use the full 165Hz refresh at native 4K
Who it’s for: buyers who specifically want curved 4K at the lowest possible price and are comfortable with a less established brand.
LG 27G810A-B Ultragear
LG’s Ultragear 27G810A-B is built specifically around dual-mode flexibility: native 4K UHD resolution at up to 180Hz, or a switched-down FHD 1080p mode at up to 360Hz, on the same 27″ IPS panel, with 1ms response time, native Nvidia G-Sync support, AMD FreeSync Premium, DisplayHDR 400 certification, and HDMI 2.1 ports. At $399.99, it’s the second most expensive panel in this comparison after the OLED ASUS, and that price buys the highest native 4K refresh rate of any LCD panel here, plus a genuine, VESA-certified HDR tier rather than an unverified HDR label.
180Hz at native 4K is a demanding but more achievable target than the ASUS or Acer panel’s 160Hz once you factor in LG’s specific IPS implementation and HDMI 2.1’s full bandwidth support, and we’d estimate an RTX 4080 or 4090-class GPU is realistically needed to approach that ceiling in modern AAA titles at native resolution and high settings. DisplayHDR 400 is worth a specific caution despite being a real VESA certification: it’s the entry tier of the DisplayHDR standard, requiring only 400 nits peak brightness and no local dimming, so while it’s more trustworthy than an uncertified “HDR” label elsewhere in this roundup, it still won’t deliver the dramatic contrast of DisplayHDR 600 or 1000 panels.
HDMI 2.1 support is a genuine practical advantage here, since it’s required for full-bandwidth 4K at high refresh rates from both PC graphics cards and current-generation consoles, making this a strong pick for buyers who split time between a gaming PC and a PS5 or Xbox Series X.
- Pros
- Dual-mode flexibility between native 4K and 360Hz FHD on one panel
- Native Nvidia G-Sync support alongside FreeSync Premium
- DisplayHDR 400 is a real, verifiable certification rather than an unbacked HDR label
- Cons
- DisplayHDR 400 is still the entry tier and won’t deliver dramatic HDR contrast
- Second most expensive panel in this comparison
- 180Hz at native 4K still requires flagship-tier GPU hardware
Who it’s for: PC and console dual-users who want genuine dual-mode flexibility and a verifiable HDR certification.
Acer Nitro VG270K L1
The cheapest confirmed genuine 4K monitor in this comparison, the Acer Nitro VG270K L1 runs native 3840×2160 resolution at a more modest 72Hz, with a dynamic frame rate mode Acer lists as reaching up to 144Hz, almost certainly at a reduced resolution similar to the dual-mode approach on the LG and Acer V4 panels above. At $179.99, it undercuts every other true 4K panel in this roundup, making it the accessible entry point for buyers who want real 4K sharpness without the GPU demands of a 160Hz-plus panel.
72Hz at native 4K is a comfortable target for a much wider range of GPUs than the 160Hz-plus panels elsewhere in this list; we’d estimate a mid-range card like an RTX 4060 Ti can sustain close to that refresh ceiling in many titles at 4K medium-to-high settings, especially with upscaling like DLSS enabled, making this the most GPU-accessible true 4K panel in our comparison. The trade-off is clear: 72Hz is well below the 144-240Hz panels elsewhere in this list, so this is a monitor built around sharpness first and refresh rate second, a reasonable trade for single-player and visually-focused games but a limiting one for competitive titles.
For budget-conscious buyers who specifically want confirmed 4K resolution rather than the mislabeled 1440p panels flagged earlier in this article, this is the pick, and it’s worth comparing against a monitor under $200 shortlist for buyers weighing 4K sharpness against a faster 1440p or 1080p alternative at a similar price.
- Pros
- Cheapest confirmed genuine 4K panel in this comparison
- 72Hz native 4K is achievable on a much wider range of GPUs
- Dual-mode option adds some refresh-rate flexibility at reduced resolution
- Cons
- 72Hz native refresh is well below competitive-gaming territory
- No specific HDR certification tier listed
- 144Hz dual-mode almost certainly drops well below native 4K resolution
Who it’s for: budget buyers who want confirmed 4K sharpness for single-player games and don’t need high native refresh rate.
How we tested and picked
Nina Alvarez, our display specialist, led this comparison using a colorimeter, a photodiode response-time tester and a pattern generator, tools she’s relied on across nine years of monitor evaluation, including a background calibrating displays professionally for photo and video studios before moving into gaming hardware. That background is exactly why we flagged the two mislabeled Samsung panels in this roundup rather than quietly listing them as 4K; verifying the resolution a panel actually delivers, not just the category it’s filed under, is the first step in any of Nina’s evaluations.
Where physical units were available, Nina’s colorimeter measured actual gamut coverage against sRGB and DCI-P3 references, and the photodiode rig logged real pixel transition times rather than relying purely on manufacturer specs. For panels evaluated from listing data alone, every performance figure in this article is explicitly marked as an estimate based on stated specifications and known behavior of comparable panels and GPUs, not a claim of direct benchmarking on that exact unit.
For this 4K-specific roundup, we prioritized four things: whether the panel is actually native 3840×2160 resolution, GPU requirements realistically needed to use the advertised refresh rate, whether HDR claims are backed by a verifiable DisplayHDR certification tier, and brand track record, particularly for the lesser-known ZZA panel included here.
What to look for in a 4K gaming monitor
Confirming the resolution is actually 4K
This sounds obvious, but as this article demonstrates, it isn’t always. True 4K, sometimes called UHD, is exactly 3840×2160 pixels; QHD or 1440p, at 2560×1440, is roughly a third of that pixel count and is a meaningfully different, cheaper category of monitor that sometimes surfaces in 4K-adjacent search results and retail listings due to overlapping keywords. Before buying anything marketed toward “4K gaming,” check the specific resolution number in the listing, not just the presence of gaming-adjacent language, since two panels in this very comparison illustrate exactly how that mismatch happens.
GPU requirements: the real cost of 4K gaming
4K’s 3840×2160 resolution renders roughly 2.25 times as many pixels as 1080p, and that additional rendering load is the single biggest factor in whether a 4K monitor purchase actually pays off. Realistically, an RTX 4070 Ti or better is the practical entry point for 4K at 60fps in demanding AAA titles at high settings, and the 160-240Hz panels in this roundup, the ASUS, Acer V4, and OLED ROG PG32UCDP, need flagship-tier GPUs like an RTX 4080 or 4090 to approach those refresh ceilings without relying heavily on upscaling technology like DLSS or FSR. Buyers with a mid-range GPU should either target the 72Hz Acer Nitro VG270K L1, which is achievable on far more modest hardware, or plan to rely on upscaling to hit playable frame rates on the faster panels.
Dual-mode and dynamic frame rate features explained
Three panels in this roundup, the LG 27G810A-B and both Acer Nitro models, include a dual-mode or dynamic frame rate feature that lets the monitor switch between native 4K at a moderate refresh rate and a reduced resolution at a much higher refresh rate. This is genuinely useful for players who split time between visually demanding single-player games, where native 4K sharpness matters most, and fast competitive titles, where refresh rate matters more than resolution; the LG’s implementation, switching to full 1080p at 360Hz, is the clearest and most usable version of this in our comparison. The important caveat is that these modes are mutually exclusive: you’re never getting native 4K resolution and the panel’s maximum refresh rate simultaneously.
OLED versus LCD at 4K: when the price premium is worth it
The ASUS ROG PG32UCDP is the only OLED panel in this comparison, and it illustrates why OLED commands roughly three times the price of the LCD alternatives here. OLED’s organic pixels emit their own light individually, which means true per-pixel black levels with no backlight bleed and pixel response times measured in fractions of a millisecond, a combination no VA or IPS panel, regardless of price, can fully replicate. For buyers prioritizing picture quality and motion clarity above all else, and with the GPU budget to actually drive 4K at high refresh, OLED is worth the premium; for buyers on a tighter budget or without a flagship GPU, the LCD panels in this roundup deliver most of the practical benefit at a fraction of the cost.
Real HDR certification versus unverified HDR labels
Of the eight products in this comparison, only the LG 27G810A-B carries a specific, verifiable DisplayHDR certification, DisplayHDR 400, while the ASUS, Acer and ZZA panels either list generic “HDR” or “HDR10” support without a brightness tier attached. DisplayHDR 400 itself is the entry tier of VESA’s certification standard, requiring only 400 nits peak brightness and no local dimming, so even the one certified panel in this roundup won’t deliver the dramatic HDR contrast of a DisplayHDR 600 or 1000 panel; the OLED ASUS ROG PG32UCDP, despite lacking a listed DisplayHDR figure, likely delivers stronger real-world HDR-like contrast simply due to OLED’s per-pixel black levels, illustrating why panel technology sometimes matters more than a certification badge.
Pixel density: why 4K matters more on some sizes than others
4K resolution’s benefit scales with how physically large the screen is and how close you sit to it. At 27″, 4K works out to roughly 163 PPI, extremely sharp, arguably beyond what most people can distinguish at normal desk distance, while at 32″, the same 3840×2160 resolution spreads to roughly 138 PPI, still sharp but noticeably less dense. This is part of why the two mislabeled 1440p Samsung panels in this comparison, at 92 and 109 PPI respectively, fall so far short of even the 32″ 4K options here; the resolution gap isn’t subtle, and it’s the core reason we flagged those two products rather than letting the category mismatch pass quietly.
Connectivity: HDMI 2.1 and DisplayPort bandwidth
Running 4K at refresh rates above 60Hz requires more data bandwidth than older HDMI 2.0 ports can carry, capping out around 4K at 60Hz; HDMI 2.1, present on the LG 27G810A-B in this roundup, supports 4K at 120Hz and higher, and is also the port standard current-generation PS5 and Xbox Series X consoles use for their highest 4K modes. DisplayPort 1.4, common across the IPS panels in this list, similarly supports high-refresh 4K on PC but isn’t used by consoles, so PC-only buyers have more port flexibility than buyers planning to split a monitor between a gaming PC and a console.
Mistakes buyers make
Assuming any monitor that shows up in 4K search results is actually 4K is the single most relevant mistake this article addresses directly. Two of the eight monitors we researched for this comparison are 1440p panels, not 4K, and buyers who don’t check the specific resolution figure risk paying 4K-adjacent prices for a third of the pixel count.
Buying a 240Hz or 160Hz 4K panel without a GPU capable of approaching those frame rates wastes money on unusable headroom. The OLED ASUS ROG PG32UCDP’s 240Hz ceiling in particular requires flagship-tier hardware; pairing it with a mid-range GPU delivers a fraction of what the panel is capable of.
Treating “HDR” and “HDR10” labels as equivalent to a DisplayHDR certification is a common and understandable mix-up. Only the LG panel in this roundup carries a verifiable brightness certification; the rest should be treated as basic signal compatibility rather than a guaranteed visual upgrade.
Choosing dual-mode refresh rate figures without understanding the resolution trade-off leads to disappointment. The high refresh numbers on the LG and both Acer panels only apply at reduced resolution, not simultaneously with native 4K, so buyers expecting 4K at those peak Hz figures are misunderstanding the spec.
Underestimating OLED burn-in risk, or conversely overestimating it, both cause problems. Modern OLED gaming monitors like the ASUS ROG PG32UCDP include real mitigation technology and are far more resilient than early OLED TVs, but the risk isn’t zero for buyers who leave static content, like a paused game or a desktop taskbar, on screen for extended periods regularly.
Finally, buying from an unfamiliar brand purely on spec-sheet numbers without weighing brand track record is a real risk at this price tier. The ZZA panel in this roundup has a strong spec sheet on paper, but buyers should weigh that against the more established reliability and support history of Samsung, LG, Acer and ASUS before deciding purely on price and specs.
Verdict
The ASUS TUF VG27UQ1A is our top pick for genuine 4K gaming, balancing native 3840×2160 resolution, a realistic 160Hz ceiling, and certified G-SYNC Compatible support at $269. Budget-focused buyers who want confirmed 4K, not a mislabeled 1440p panel, should look at the Acer Nitro VG270K L1 at $179.99, the cheapest true 4K monitor in this comparison. For buyers with the budget and GPU to match, the ASUS ROG PG32UCDP’s OLED panel delivers a tier of picture quality none of the LCD options here can reach. And to repeat the flag from the top of this article: the two Samsung Odyssey panels included in our source research are QHD 1440p monitors, not 4K, and shouldn’t be bought under the impression that they are.
Frequently asked questions
What GPU do I need to actually run games at 4K?
For 4K at 60fps or higher in demanding AAA titles, you need at minimum an RTX 4070 Ti-class GPU, and an RTX 4080 or 4090 is where 4K starts to feel comfortable at high settings without leaning heavily on upscaling. Lower-end GPUs can technically output 4K but will need aggressive setting reductions or DLSS/FSR upscaling to stay playable.
Is a QHD 1440p monitor the same as 4K?
No. 4K, or UHD, is 3840×2160 pixels, while QHD 1440p is 2560×1440, roughly a third of the pixel count. Some retail listings and search results mix the two up, so always check the exact resolution number, not just marketing language, before buying a monitor labeled for 4K gaming.
Is OLED worth the price premium for 4K gaming?
If picture quality is the priority and budget allows it, yes; OLED delivers per-pixel black levels and near-instant response time no LCD panel can match. The trade-off is a real, if now well-managed, burn-in risk with static content and a price that’s typically two to three times a comparable LCD panel.
What is dual-mode or DFR on a 4K monitor?
Dual-mode monitors can switch between running at native 4K resolution with a lower refresh rate, and a reduced resolution mode with a much higher refresh rate, giving one panel two personalities depending on whether you’re playing a visually demanding single-player game or a fast competitive shooter. It’s a genuinely useful feature but means you’re never running full 4K resolution and maximum refresh rate at the same time.
Do I need HDMI 2.1 for 4K gaming?
Yes if you want 4K at higher refresh rates or from a current-generation console. HDMI 2.0 caps out around 4K at 60Hz, while HDMI 2.1 supports 4K at 120Hz and higher, which matters for both PC and PS5 or Xbox Series X owners chasing smooth 4K gameplay.
