HP Omen 27U Gaming Monitor Review: An Unassuming Choice for

There aren’t a ton of gaming displays in the identical class as HP’s Omen 27U. While it is one of many higher-priced fashions of its aggressive cohort at $700, it stands out from the competitors for quite a lot of causes. Notably, it has an HDMI 2.1 reference to help for variable refresh and 4K 120Hz when linked to an Xbox Series X or VRR on the PS5 — a characteristic that is beginning to acquire traction for gaming shows. And it is available in a smooth design you do not often see in a gaming monitor, even once you mild it up, together with a purposeful structure for the connectors that is additionally uncommon. 

The monitor is not obtainable internationally, however $700 converts to roughly £570 or AU$1,020.


  • Well designed, with comparatively easy accessibility to connections
  • Console VRR and 4K at 120Hz suitable

Don’t Like

  • The built-in audio system aren’t value it
  • No downstream USB-C connection
  • Stand does not enable for swivel

The monitor is DisplayHDR 400 licensed, however that simply means it is brighter than common with presumably a broader coloration gamut than a typical monitor. Most of the present opponents at this value are the identical. But when you’re really on the lookout for a monitor to make use of for HDR, look to at least one with DisplayHDR 600-level specs, just like the equally priced LG Ultragear 27GN950. That mannequin does not help VRR on consoles, so there’s your tradeoff.

The HP additionally consists of built-in stereo audio system, although they’re low energy, 2-watt variations which are principally good for system notifications and equally undemanding audio. It additionally has a small USB hub with two USB-A connections, however sadly no USB-C out.

I’ve grown fairly keen on the 27U’s design since HP debuted the model a number of years in the past. The connections sit on both aspect of a diamond-shaped part that homes the electronics; which means they’re dealing with the perimeters moderately than the desk, which makes it simpler to get to them. And its high-to-low place ranges over 130mm in contrast with most displays’ 110mm vary. Plus the stand has a headset hook, when you desire them unseen when not in use.

The show behaves as anticipated when linked to an Xbox Series X, which means it should robotically sense the connection coming on-line once you activate the console and can set the refresh charge to 120Hz.

It has the same old set of game-specific options, like a crosshair, framerate show, fudgy shadow boosting and so forth. It’s received an MPRT mode to compensate for movement blur, which solely works at refresh charges over 100Hz and in SDR. This visibly lowers the brightness as you degree it up, in addition to a number of velocity settings for pixel response, half of which lead to unhealthy halos round transferring objects.

There’s a single Game preset, which is actually the Native mode with decrease brightness and the proper tone curve for HDR when it is enabled. You have no actual HDR choices: When you flip it on in Windows, or on the console, it is on. Because of the around-the-edge backlight, it has little management over native distinction — HDR solely actually appears to be like like HDR when the brilliant and darkish areas subsequent to one another pop. That, mixed with the low peak brightness, makes it much less HDR and extra SDR-plus. That’s sadly true of many “HDR” displays.

There can be a novel Game Remaster mode, which “robotically applies enhancement filters to lower-resolution video games.” I attempted it with the unique Fallout and could not see any distinction. Your mileage might range, although.

I’d say the monitor delivers pleasing, moderately than correct, colours. HP says the monitor is factory-calibrated, however my measurements had it excessive throughout the board by roughly 500 levels Kelvin, together with within the Warm (5,000K) and Cool (9,300K) presets. In different phrases, graphics had been slightly cooler and bluer than they need to have been. Decreasing the blue acquire from 255 to 240 put all of the numbers roughly again in step with HP’s claims. If you are not delicate to paint temperature, although, you most likely will not discover: It’s not that far out of whack. If you need to get the tone curve to a strict 2.2 gamma, you’d need to calibrate the monitor.

“Pleasing” might be the adjective that the majority fits the Omen 27U usually. It’s not the bestest in its class, however the nice design and console compatibility elevate it above what it would in any other case charge. I do not know that it is a good selection for the normal, hardcore PC gamer, however when you want a show for a small area that appears good, works effectively and, oh sure, is nice for gaming on a PC in addition to console, the 27U ticks all of the packing containers.

How we check displays

All measurements are carried out utilizing Portrait Displays’ Calman Ultimate 2021 software program utilizing a Calibrite ColorChecker Display Plus (previously X-Rite i1Display Pro Plus). We use a Murideo Six-G sample generator for HDR testing the place crucial, or the Client3 HDR patterns inside Calman, the place potential. The extent of our testing depends upon the capabilities of the monitor, the display and backlight expertise used and the judgment of the reviewer.

On essentially the most primary fashions, we might keep on with simply brightness, distinction and coloration gamut, whereas on extra succesful shows we might run assessments of most user-selectable modes for gaming or color-critical utilization, uniformity and so forth. For the colour work, we can also run assessments to confirm how white level accuracy varies with brightness.

Color accuracy outcomes reported in items of Delta E 2000 are based mostly on Calman’s commonplace Pantone patch set, plus the grayscale and pores and skin tone patches. White factors outcomes are based mostly on each the precise white worth plus the correlated coloration temperature for your entire grey scale (21 patches, 0 to 100%) rounded to the closest 50K so long as there aren’t any large variations. We additionally use Blur Bustersmotion tests to evaluate movement artifacts (corresponding to ghosting) or refresh rate-related issues that may have an effect on gaming.
