Overview
Dolby Vision on a gaming OLED is the detail worth noticing here, because almost no gaming monitor decodes it - it is normally reserved for TVs and a handful of creator panels. Asus pairs it with DisplayHDR 500 True Black and HDR10 on a 31.5-inch 4K QD-OLED running 24-240 Hz, with a 0.03 ms response, 99% DCI-P3 and both G-Sync Compatible and FreeSync Premium Pro. A 90 W USB-C port and OLED Care Pro round it out. The awkward part is the stand: 80 mm of height, +/-15 degree swivel and no pivot is thin for a monitor at this price, and there are no speakers. Worth noting too that the sheet lists typical and peak brightness as identical at 1000 cd/m2, which is unusual and probably a spec-sheet quirk rather than reality.

HDR & Brightness Reality
The format stack is what makes this unusual: Dolby Vision alongside DisplayHDR 500 True Black and HDR10 means supported films tone-map scene by scene on a panel with genuine self-lit blacks. Peak brightness is 1000 cd/m2 for highlights. One caveat on the numbers - the sheet lists typical brightness as 1000 cd/m2 too, identical to peak, which is not how OLED panels behave; full-screen output is realistically far lower. Treat the peak as real and the typical figure as a spec-sheet error until you see it measured.

Frequently Asked Questions
01 Why does Dolby Vision matter on a gaming monitor? +
Because it almost never appears on one. Dolby Vision tone-maps scene by scene rather than using a single static curve, so supported films look closer to how they do on a good TV. Most gaming panels stop at HDR10.
02 What is the point of a 24 Hz refresh floor? +
Cinema is mastered at 24 fps. A panel that can actually run at 24 Hz displays film cadence without judder or 3:2 pulldown. Most monitors start at 48 Hz, so this is a deliberate film-friendly choice.
03 Is the stand really that limited? +
✓ Yes, and it is the odd part of the package. You get 80 mm of height, +/-15 degrees of swivel and no pivot at all - less than monitors costing half as much. Budget for a VESA arm.
04 Why does the spec sheet list typical and peak brightness as the same? +
It almost certainly should not. OLED panels produce far lower full-screen brightness than peak highlight brightness - typically 250-300 cd/m2 against a 1000 cd/m2 peak. Read the 1000 typical figure with scepticism.
05 How does it compare with the MSI MPG 322UR? +
Same panel class - 4K QD-OLED at 240 Hz. The MSI has better connectivity (98 W USB-C, KVM) and this Asus has Dolby Vision and a 24 Hz floor. The Asus stand is the weaker one.
