Our Verdict
Samsung Q90/Q90T QLED
LG C9 OLED
Overall, the LG C9 OLED is better than the Samsung Q90/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.
