Our Verdict
LG C4 OLED
Roku Pro Series QLED
The LG C4 OLED is much better than the Roku Pro Series QLED. The Roku has fantastic contrast, but the LG is an OLED, so it has even better contrast for a more immersive dark room experience. The Roku is a bit brighter in HDR and much brighter in SDR, but the LG has vastly better reflection handling, so it looks better than the Roku in most lighting configurations. Otherwise, the LG offers better image quality across the board, is more accurate, and is overall the far better option for almost anyone.
