Our Verdict

Samsung S90H OLED

Samsung 77S90H OLED

The Samsung 77S90H OLED is better than the other sizes of the Samsung S90H OLED. The 77-inch version specifically uses a different type of OLED panel, which delivers much brighter, more vibrant colors. Although it still relies on a white subpixel, bright colors aren't nearly as washed out in light scenes, so most content, especially in HDR, is more colorful. Other than that, though, these are essentially the same TV.

Samsung 77S90H OLED Samsung S90H OLED LG C6H OLED LG C6 OLED 2026 I tried to compare the above tv’s. I am trying to pick one for gaming and see their performance as 42", 48", 55" and 77". If I am correct LG C6 in its 48" size has brightness booster and tandem panel type just like compared model of LG C6H above in the 77" size. LG C6 42" does not have brightness booster and tandem panel however LG C6 55" version has brightness booster but does not have tandem panel. Samsung S90H in its 48" has RGB tandem panel type just like compared model of Samsung 77S90H above in the 77" size. Samsung S90H 42" does not have RGB tandem panel type but it has Standard WOLED just like Samsung S90H 55". Is my comparison accurate and 48" and 77" version in both of those LG and Samsung tv’s seam to be better than 42" and 55"?

You nailed it! All of these differences are hard to keep track of, so good job with that. The only thing I’ll add is that the 48" C6 and S90H aren’t quite as bright as the 77" models. We actually reviewed the 48" C6 as a monitor, so if you haven’t seen that review yet, it might be worth checking out! The 48" S90H will perform almost identically in terms of brightness as the 48" C6, since they use identical panels.
