ASUS PA27USD

The ASUS ProArt PA27USD is a 26.5-inch 4K QD-OLED with 240Hz refresh and best-in-class color accuracy, packing a built-in motorized colorimeter and 12G SDI for professional video workflows. It's one of the most well-connected monitors we've ever tested, with dual Thunderbolt 4 and a KVM switch. Pricing varies wildly from $2199 to $3320, so shop carefully. If you need a reference monitor that doubles as a high-end gaming display, this is the one to beat.

The PA27USD's QD-OLED panel is a straight-up showstopper. In our testing database, its color performance sits at the very top, best-in-class accuracy with a Delta E under 1 right out of the box. That means colors are so precise you'd need a spectrophotometer to find fault, and ASUS even includes one in the monitor to keep it that way. The 240Hz refresh rate combined with the near-instant 0.1ms response time makes motion clarity phenomenal, whether you're scrubbing through a 4K timeline or tracking a Pharah in the sky. This isn't just a fast OLED, it's one of the fastest 4K panels you can buy right now, putting it in the top tier for overall performance.

HDR content looks stunning thanks to that 1000-nit peak brightness and the per-pixel illumination of OLED. Blacks are truly black, with a 1.5 million to one contrast ratio that makes every shadow detail pop. The monitor supports HDR10, HLG, and Dolby Vision, so you're covered whether you're mastering for Netflix or just watching a movie. The 10-bit panel handles 1.07 billion colors without banding, and the 99% DCI-P3 gamut means you're seeing the full color space modern content is mastered in. For creative work, this is about as good as it gets without spending five figures on a true mastering monitor.

The PA27USD sits in a weird spot where it competes with both professional monitors and high-end gaming OLEDs. Against something like the Dell UltraSharp U4025QW, the ASUS absolutely demolishes it in refresh rate and response time while matching or exceeding color accuracy. The Dell is a bigger ultrawide aimed at productivity, but it can't touch the ASUS for HDR content creation or gaming. On the gaming side, the MSI MAG 271QPX QD-OLED E2 and Samsung Odyssey G60SD both use similar QD-OLED panels and offer excellent color, but they lack the hardware calibration, SDI input, and Thunderbolt connectivity that make the ProArt a true professional tool.

The Gigabyte MO27U2 SA is another 4K OLED competitor that undercuts the ASUS on price, but again, it's purely a gaming and general use monitor. It doesn't have the colorimeter, the SDI, or the factory calibration guarantees. If you're a video professional who needs SDI for broadcast or cinema camera workflows, none of these gaming monitors can replace the PA27USD. The LG UltraGear 45GX950A-B is a different beast entirely, a massive ultrawide with a more aggressive curve, but it's aimed at immersion rather than color-critical work. The ASUS is the only monitor in this group that a post house would actually consider rack-mounting.

Pricing on the PA27USD is all over the map right now, with vendors listing it anywhere from $2199 to $3320. That's a massive $1121 spread, so shopping around is absolutely critical. At the lower end of that range, you're getting a professional-grade reference monitor and a top-tier 4K gaming display in one package, which starts to look like a decent deal if you'd otherwise buy two separate monitors. At the high end, you're creeping into territory where you could almost grab a smaller Flanders Scientific or Sony reference monitor, though those won't give you 240Hz or built-in gaming chops.

Compared to the competition, the value proposition hinges entirely on that built-in colorimeter and the SDI input. If you don't need those pro video features, you can get a fantastic 4K OLED gaming monitor like the MSI MAG 271QPX for significantly less. But if you're a colorist or DIT who needs SDI for on-set work and wants to game at home, this monitor consolidates your setup in a way nothing else on the market does. Just make sure you're buying from the vendor with the best price, because paying an extra grand for the same panel would sting.

ASUS crammed a colorist's dream and a gamer's fantasy into the same 26.5-inch panel with the ProArt PA27USD, and somehow it mostly works. This is a 4K QD-OLED running at a buttery 240Hz with true 10-bit color and a factory calibration so tight it lands in the absolute top tier of our database for color accuracy. We're talking about a monitor that ships with a motorized flip-out colorimeter built right into the bezel. If you're a professional video editor, colorist, or photographer who also wants to frag out in Overwatch after work, this thing was built for you. It's a very specific, very expensive Venn diagram, but ASUS went all in on it.

The spec sheet reads like a wish list for a post-production studio that moonlights as an esports arena. You get 99% DCI-P3 coverage, Dolby Vision support, a peak brightness of 1000 nits for HDR highlights, and a 0.1ms response time that makes motion look impossibly crisp. Connectivity is bananas, with dual Thunderbolt 4 ports pushing 96W of power delivery, HDMI 2.1, DisplayPort 2.1, and even a 12G SDI input for uncompressed 4K60 playback from professional cameras and decks. It's one of the most well-connected monitors we've ever seen, landing in the 98th percentile for connectivity.

But here's the catch, and it's a weird one. The built-in colorimeter, the killer feature that sets this apart from every other OLED on the market, makes noise. Not a little whir, but a noticeable mechanical sound during calibration that one of the few early buyers found distracting enough to mention in their review. For a monitor aimed at professionals who might calibrate daily, that's something to think about. Still, for the right person, this is a no-compromise display that does double duty as a reference monitor and a high-refresh gaming beast.

If you don't work with SDI video sources or need hardware calibration, a huge chunk of this monitor's price tag is paying for features you'll never touch. Pure gamers should look at the MSI MAG 271QPX or Gigabyte MO27U2, which use similar QD-OLED panels and deliver the same 240Hz 4K experience for hundreds less. The gaming performance is nearly identical, and you won't miss the colorimeter or SDI port in a gaming setup.

Also, if you work in a shared or quiet studio where mechanical whirring during calibration would be a problem, this might drive you nuts. A traditional external colorimeter paired with a quieter professional monitor like an Eizo or a high-end Dell UltraSharp could be a better fit. And if portability matters at all, this monitor scored terribly in our portable metric, it's heavy and meant to stay put on a desk or in a rack.

For the hybrid professional who edits color-critical video by day and games by night, the PA27USD is basically a dream come true. The built-in colorimeter means you can schedule automatic calibrations and trust that your colors are accurate without hauling out an external probe. The SDI input is a genuine differentiator for broadcast and cinema workflows, and the 240Hz panel means you're not sacrificing gaming performance for color accuracy. If your workflow involves SDI cameras or decks and you want one monitor to rule them all, this is it. Just budget for it and shop around for the best price.

If you're purely a gamer who appreciates good color but doesn't need hardware calibration or SDI, you should probably save your money and grab something like the MSI or Gigabyte OLEDs. They'll give you 90% of the visual experience for a lot less cash. And if you're a colorist working in a quiet suite, the calibration noise might genuinely bother you. In that case, a traditional external colorimeter paired with a quieter monitor might be the better call. But for the right person, the PA27USD is a singular, uncompromising tool that does two jobs exceptionally well.
