Our HDR benchmarking uses Portrait Displays’ Calman software. To learn about our HDR testing, see our breakdown of how we test PC monitors.

The XB273U NVbmiiprzx has two HDR modes. If you set the OSD option to Auto, it works well but doesn’t quite pop as much as the HDR400 option, which delivers higher brightness and better image depth.

HDR Brightness and Contrast

The XB273U easily exceeds its DisplayHDR 400 certification with a 422.65 nits brightness with HDR. The Viotek and Asus screens offer a bit more, but anything over 400 nits is very bright. The XB273U’s second-place black level of 0.08 nit clearly shows the effect of dynamic contrast. 

Even MSI’s VA panel isn’t that dark because it relies on its native contrast for both SDR and HDR. Resulting contrast for our review focus is a healthy 4,987:1, which is among the best we’ve measured for a monitor with an edge backlight, which won’t yield as premium results as a FALD backlight. The Asus is an overachiever here with one of the highest HDR contrast ratios we’ve recorded to date.

Grayscale, EOTF and Color

The XB273U’s HDR grayscale, EOTF and color performance leave no room for complaint. Grayscale tracking is visually perfect. Most monitors have some issue at the tone-map transition point, but not this Predator. The luminance curve tracks almost perfectly with dark shadows, well-defined mid-tones and highlights that pop.

Color tracking is mostly on-point with a slight undersaturation at the inner targets but full realization at the gamut perimeter. Only green comes up short of the full volume and by about the same margin as most DCI-P3 screens. Secondaries are at the correct hues and near their saturation targets too. These charts show the XB273U NVbmiiprzx delivers excellent HDR accuracy.

    Jeez. And I thought Intel had a messed up naming convention. This NVbmiiprzx , GSbmiiprzx and GXbmiipruzx as model differentiators!! Wow! Where do they get their marketing teams from!! :ROFLMAO:

    Okay, I get NV/GS/GX, but the rest!

    If you're looking for a great {near}top-tier monitor check out the Dell 3220DGF!

    It's 165hz, 32" VA Panel with amazing blacks, gsync compatible, and comes with the amazing Dell Display Manager software. I'm loving it!

    The Acer Predator XB273U NVbmiiprzx gaming monitor delivers 170 Hz and G-Sync in a 1440p IPS panel. It’s highly accurate and worth considering for any high-performance gaming system.

    According to the review it seems this monitor should have gotten a score higher than 4 stars. The Asus ROG Strix XG27AQ got 4.5 stars and it is $50 cheaper. Maybe that is why it got 4.5 stars. On the other hand, the XG27AQ has, "...Superb image with one of the best dynamic contrast features we’ve seen. "

    But this Acer has "VisionCare and a TUV Rheinland Eyesafe certification. This takes the form of a low blue light mode and a room light sensor, which can vary brightness and color temperature to better match ambient room light and reduce user eye fatigue. ...The NV is also a 10-bit panel." The Asus is 8-bit. This is a tough decision for me. The Acer doesn't seem to have a manual and the Acer does. That is significant.
