Our Verdict

Samsung Q90/Q90R QLED

LG C9 OLED

The Samsung Q90/Q90R and the LG C9 use different panel types, each with their advantages and disadvantages. The C9 looks much better in a dark room, as the OLED panel delivers a nearly infinite contrast ratio and near-perfect black uniformity. The Q90R is significantly brighter, and the brightness doesn't change as much with different content (ABL). The C9 has better gray uniformity and better viewing angles. The C9 has a risk of permanent burn-in when exposed to static content, but the Q90 doesn't.
