Our Verdict
LG C5 OLED
Samsung S90F OLED
The LG C5 OLED and the Samsung S90F OLED trade blows. They're about equally as bright in most HDR content, although the S90F is far brighter in Game Mode. In SDR, however, the C5 is way brighter. The S90F does handle direct reflections better, but the C5's black levels barely raise in bright environments, while the S90F's blacks become charcoal gray in the same context. The S90F's QD-OLED panel is far more colorful than the C5's WOLED panel, which is expected. They're about equally as good for gaming, although the C5's Dolby Vision support does give it the slight edge for Xbox gamers.

LG C5 OLED vs Samsung S90F OLED: Main Discussion
What do you think of these products? Let us know below.
Looking for a personalized buying advice from the RTINGS.com experts? Insiders have direct access to buying advice on our insider forum.
I double checked our unit running the latest available OTA update: 33.21.67 and didn’t see any changes from our current measurements in our review. Hopefully this helps and thank you for reaching out!
Does anybody know if the C5 still loses a significant amount of brightness in game mode? I’ve read online that some people are saying it has been patched with a firmware update. Can anyone confirm this?
