HDR Functioning

Aside from the size, the other key reason to buy the Momentum 43 is its HDR capabilities, in particular DisplayHDR thou certification. What nosotros're getting here on the spec sheet is really pretty proficient as far equally monitors are concerned, we oftentimes see companies slapping "HDR" onto their monitor boxes without tackling even i of the iii key HDR pillars, but in this case Philips has fabricated an endeavour to provide an HDR experience that exceeds SDR, and that shows with DisplayHDR one thousand certification.

Nosotros go over 700 nits of sustained effulgence and chiliad nits meridian, so Philips has smashed that target. We as well see an increased colour space of 145% sRGB, a 10-bit panel through FRC, and local dimming. All the same the big omission here is an FALD or full array local dimming backlight; the Momentum 43 only features border lit dimming in 32 zones. And then unfortunately this panel doesn't see everything in my HDR checklist.

And permit'due south talk about the edge lit dimming for a moment hither. 32 zones is larger than what you see with Samsung'southward HDR panels, for example, simply it's yet nowhere near the level of the 384-zone FALD backlight y'all get with Asus and Acer's Grand-Sync HDR monitors. The big issue with edge lit dimming is information technology tin't prove bright objects in the eye of the display without producing a noticeable glow that extends from the edges of the display, to the bright object. VA's excellent native contrast helps mitigate this issue somewhat compared to IPS, simply the glow is still present and in a dark viewing environs, it'south noticeable. Each lighting zone also appears a picayune slow to reply compared to other HDR displays I've used.

While I could slam Philips more for using edge lit local dimming, the reality is this monitor'south HDR mode does provide an improvement over SDR because it comfortably provides two of the three primal HDR pillars in effulgence and color infinite. And in a lot of situations, the edge lit backlight does assistance meliorate the dynamic range and contrast of scenes. So it's not like the HDR feel is awful because it lacks an FALD backlight, it'south definitely meliorate than SDR. Just the feel isn't as good equally with a proper HDR display that ticks every box, so I'd grade the Momentum 43 as an HDR-lite display or something along those lines.

The good news is that the areas of HDR that the Momentum 43 does support, like effulgence and color space, it supports really well. The panel can comfortably sustain over 900 nits of brightness regardless of the window size, and while peak effulgence doesn't quite hit 1000 nits, the 935 nits my unit can produce is absolutely blinding at a desk-bound viewing distance. When you lot're non experiencing the glow bug from the edge lit backlight, we're likewise getting a contrast ratio over 40,000:1 in a best case scenario, which is groovy. And every bit for color infinite, 97% DCI-P3 coverage means the brandish tin show a significantly college number of colors than basic sRGB, which leads to more than vibrant imagery in the HDR manner.

Also, at that place are several different HDR modes, I recommend using the DisplayHDR 1000 mode for the best operation.
