Our HDR benchmarking uses Portrait Displays’ Calman software. To learn about our HDR testing, see our breakdown of how we test PC monitors.
The one place where the 34M2C7600, and its Mini LED counterparts, runs away from the competition is peak brightness. DisplayHDR 1400 is the order of the day and that, along with 1,152 dimming zones, makes a huge difference in image quality.
HDR Brightness annd Contrast
When measuring a full field, the 34M2C7600 renders around 1,100 nits, so I reduced the pattern to 25% coverage and got almost 1,500 nits. Small highlights are extremely bright and really help the image pop. Philips has engineered its local dimming very well here. I couldn’t measure the black levels as all unused LEDs are shut off, so the contrast is also unmeasurable. Though the ASRock effectively extends its dynamic range to an excellent 16,907:1, it doesn’t hold a candle, or a diode, to the Mini LED screens. Only a good OLED like Asus’ PG27AQDM can deliver a deeper image than this.
Grayscale, EOTF and Color
There are five HDR picture modes, but the only one remotely close to color accurate is DisplayHDR 1400. The default one, Game HDR is extremely red in tone, and the others don’t deliver the proper luminance tracking for optimal performance. You can see visually perfect grayscale tracking from bottom to top and an EOTF that is flawed only in its darkest steps. The 34M2C7600 rises too slowly from black, which means some shadow detail may be hard to see in some games. It’s too bad you can’t use the Shadow Boost feature to fix this, but it is grayed out. Most HDR games have luminance tweaks in their menus, so I turned to dial in the image on a per-title basis.
HDR color is rich and vibrant with excellent saturation tracking. Most points are on target or a little over-saturated which is forgivable. Hues are spot-on, which means the image is always natural and pleasing. The DCI-P3 and Rec.2020 charts exhibit the same performance, which is a good thing. Most HDR content is mastered in the Rec.2020 gamut and the 34M2C7600 comes close to covering it. Thanks to accurate grayscale, luminance tracking and a very wide color gamut, the 34M2C7600 is one of the better HDR monitors out there. It truly does justice to the format.
