A 1,500,000:1 contrast ratio is the number that actually matters here, and it's the reason this is the monitor we point people to when they ask what HDR looks like. Every pixel switches off individually, so a night sky, or the black bars around a movie, stays black instead of glowing grey the way an edge-lit LCD does. VESA rates it DisplayHDR 400 True Black — a modest figure that measures the black level rather than the peak, which is exactly the part you notice.
The TrueBlack glossy coating is what we ended up appreciating most. Highlights in games and HDR video have a hard edge that matte panels soften, and color arrives saturated without the neon push that cheaper HDR modes layer on top of an SDR picture. We also spent time with the 240Hz refresh and 0.03ms response; that is more speed than a workday needs, but scrolling a long document at 240Hz makes 60Hz feel like a compromise.
Color holds up under scrutiny: 99% DCI-P3, true 10-bit, and Delta E under 2 mean an HDR grade lands close to where it was mastered. Living with it, we came to trust the OLED Care Pro proximity sensor, which blanks the panel when you step away — the least intrusive burn-in hedge we've used. The port count is the one place it runs tight: a single HDMI alongside one DisplayPort and two USB, so a console and a PC sharing a desk need a plan.
Three years of warranty that explicitly covers burn-in is the reassurance that matters on an OLED, and it's more coverage than most of this group offers. It's also the most expensive monitor here by a wide margin. If you want the format rather than a feature checkbox, that's money well placed.
Pros
- Per-pixel OLED contrast with true blacks
- 99% DCI-P3 with Delta E under 2
- 240Hz refresh and 0.03ms response
- Three-year warranty includes burn-in
Cons
- Glossy panel reflects windows and lamps
This is the monitor we recommend when HDR is the reason you're shopping: per-pixel OLED contrast, 99% DCI-P3, and 240Hz, with burn-in coverage behind it.
