To compare the Omen 27u’s performance, I’ve gathered Ultra HD displays ranging from 27 to 32 inches in size. All are edge backlight IPS panels running at 144 Hz. We have Philips’ 329M1RV, the Eve Spectrum D03, Asus’ VG28U, Acer's XV282K and LG’s 27GN950.

Pixel Response and Input Lag

The Acer draws a full white field 1ms quicker than the rest. That gives it a slight edge in smoothness with a tad less motion blur. In practice, the difference is very small. The rest, including the Omen 27u, hit 7ms which is typical for a 144 Hz monitor.

Total input lag is right in the middle at 32ms. The LG is a standout here; one of the few 144 Hz monitors that is significantly quicker than 30ms. Gamers of average ability will have no problem enjoying play on the Omen 27u. It has similar levels of motion blur and responsiveness to its competition.

Viewing Angles

The Omen 27u has reasonable viewing angles with very little loss of brightness at 45 degrees to the side and a slight green tint. You can still see all the pattern steps clearly with no change in shadow detail. The top view is blue with a washed-out look, which is typical of the IPS category.

Screen Uniformity

My Omen 27u sample scored very well in the uniformity test with no visible hotspots, bleed or glow. The edge backlight kept things nice and smooth at all brightness levels and all colors when I viewed full-field patterns. There is no reason to expect issues with any example of this monitor.

    Mfg's should not be allowed to label something "HDR" with an edge lit panel and no local dimming.
    It's fake "HDR" at best.

    700$ is one garbage price to pay to get 144hz at 4k

    there's no way 144hz cost them more vs a 60hz model to make; it's pure price gauging

    It's been 7+ years and we're still at 700$+ for high refresh 4k; I just don't buy it:rolleyes:

    32 ms input lag?? You sure?? I just bought it but I'm going to return the bloody thing. That is way too slow. Who wants 32 ms input lag! What monitor has 32 ms input lag these days? Ouch!! Or did you meant 3.2 ms. Cause 3.2 or 32 is a huge difference!
    If this is a mistake I would change it in the article cause no one will buy this monitor. I almost got a heart attack reading this! Going to return it.. This is bad if 32 ms input lag is the real thing..
