If you prefer deeper blacks and more vibrant colors for movie watching in dark environments, the LG C2 OLED would be an excellent choice, yet OLED screens face a higher risk of burn-in with static images which might be a concern if you plan to use it for gaming or as a PC monitor. On the other hand, the Samsung QN90C LCD will serve better in bright rooms due to its superior brightness and doesn't have burn-in issues, making it a good pick for varied use, including daytime TV watching and as a gaming monitor. The higher cost of the Samsung QN90C might be justified by its versatility and screen longevity, especially if the TV is often used during the day or for content with static elements. Give Feedback

CNET

David Katzmaier | November 2022
"The C2 offers image quality that's a clear step above any non-OLED TV I've seen. The C2 is rare among high-end TVs in that all four of its HDMI ports support 4K/120, great for hard-core gamers with multiple next-gen devices. The C2 is plenty bright enough for just about any viewing environment. It also outperforms QLED TVs like the Samsung QN90B and TCL 6-Series. That's why I consider the LG C2 the best high-end TV for the money of 2022."
