HDR & Brightness Reality
DisplayHDR 400 with a 500 cd/m2 peak gives you a hundred nits of headroom above the panel's typical 400 - technically more than nothing, practically not enough for HDR to look like HDR. There is no local dimming listed. What genuinely improves the picture is the 3000:1 native contrast, and that works the same in SDR. The sensible approach on this panel is to leave HDR off and let the VA contrast do the work it is good at.

Frequently Asked Questions
01 Why did Alienware use VA here instead of IPS? +
Cost and contrast. VA gives 3000:1 against roughly 1000:1 on the IPS Alienwares, so dark games look better - and VA panels are cheaper, which is how this lands below the AW2723DF and the OLED models.
02 What does a 1500R curve feel like? +
It sits between the gentle 1800R most ultrawides use and the aggressive 1000R of BenQ's Mobiuz. Noticeable but not opinionated - it works at typical desk distance without demanding you sit dead centre.
03 Can I swivel it to show someone? +
No. The stand tilts from -5 to +21 degrees and raises 110 mm, but there is no swivel and no pivot. On an 805 mm wide panel, that is a genuine limitation.
04 Is DisplayHDR 400 worth using on this? +
Not really. 500 cd/m2 peak against 400 typical is barely any headroom, and there is no local dimming. The 3000:1 contrast in SDR is the better picture.
05 How does it compare with the AW2723DF? +
Different priorities. The 2723DF is 27-inch 1440p Fast IPS at 280 Hz with DisplayHDR 600 and a 700 nit peak - faster and brighter. This is wider, cheaper, and has triple the contrast.
