OLED pixels emit their own light, so they can turn completely off for true blacks and ‘infinite’ contrast. This delivers superb dark-room performance and wide viewing angles. LCDs (QLED/Mini-LED) use a backlight, which can be brighter but can’t hit the same per-pixel black levels.

Modern OLEDs include protections like pixel-shifting, logo dimming, and panel refresh. Burn-in is uncommon with varied content, but long sessions with static elements (news tickers, HUDs) increase risk. Use screen savers, enable logo protection, vary content, and keep brightness reasonable.

Newer OLEDs get much brighter than older models and handle highlights well, but most LCDs still win at full-screen brightness. In very bright rooms, use an anti-reflection setting, close shades when possible, or consider a high-brightness Mini-LED. In dim/normal rooms, OLED excels.

Yes, near-instant pixel response, low input lag, and features like 120Hz/144Hz, VRR, and ALLM make OLEDs excellent for gaming. To minimize image retention from static HUDs, use logo luminance reduction and mix up game titles or content periodically.
