BEST HDR
1,000-nit QD-OLED peak with per-pixel dimming and 1.5M:1 contrast — the reference for HDR highlights and true blacks.
✓
SHARPEST 4K
166 PPI on a 27-inch 4K panel — the highest pixel density of any monitor here.
✓
DOLBY VISION
One of the few monitors with Dolby Vision dynamic tone mapping — beats HDR10's static metadata on Netflix and Apple TV+.
✓
FAST + FUTURE-PROOF
240Hz at 4K, 0.03ms response, and DP 2.1a UHBR20 (80Gbps, no DSC compression).
✓
BURN-IN GUARD
Custom heatsink plus a Neo Proximity Sensor that dims the panel when you step away.
✓

■  The catch — co-equal billing, always

It's OLED, so it can burn in. Leave a taskbar, game HUD, or spreadsheet on screen 8+ hours a day and you risk permanent image retention — and the glossy coating throws glare in a bright room. If your monitor lives on a static desktop all day, buy mini LED instead.

Dealbreaker? Runner-up №2 — the KTC mini LED — has zero burn-in risk ↓

■  Every product has a catch. Verdicts that hide it are how bad buys happen.

Adjacent verdicts — same method

for just me under $250 gaming TVs with HDMI 2.1 high-refresh gaming monitors

Traps — this verdict avoids

Trap 01

The 1,000-nit lie

Advertised 1,000-nit HDR is measured at a 3% window — full-screen white on most QD-OLED panels drops to just 250 nits. Mini LED holds brightness across the whole screen.

Trap 02

Zone-count roulette

Mini LED HDR is only as good as its zone count — below 500 zones, halos bloom around bright objects on dark backgrounds. Every mini LED here runs 1,152 zones.

Trap 03

Burn-in on the desktop

OLED panels risk permanent burn-in from static content — taskbars, HUDs, spreadsheets over 8+ hours a day. If your monitor shows a fixed desktop all day, choose mini LED instead.
