Our Verdict

Samsung Q90/Q90T QLED

LG C9 OLED

Overall, the LG C9 OLED is better than the Samsung Q90T QLED. Due to OLED's emissive technology, the LG can produce perfect blacks. The LG also has better uniformity, faster response time, and it supports NVIDIA's G-SYNC to reduce screen tearing when gaming. However, the Samsung can get much brighter, it has lower input lag, and there's no risk of permanent burn-in.
