Which is better for gaming, the S90D or the C2?

The S90D. It runs up to 144Hz and has four full HDMI 2.1 ports, while the C2 tops out at 120Hz. Both support VRR, so either is a good console TV.

Is the LG C2 still worth buying in 2024?

Yes, if the value is right. Its OLED evo picture and webOS hold up well, but it is two years older and lacks the S90D's brightness and 144Hz panel.

Which handles bright rooms better?

The Samsung S90D. Its QD-OLED panel is brighter and it has an anti-reflection screen, while the C2's glossy coating reflects more light.

Does either TV support Dolby Vision?

No. Samsung does not support Dolby Vision on the S90D, and the LG C2 supports Dolby Vision but not HDR10+. Both handle standard HDR10.

Which has better sound without a soundbar?

The LG C2. Its 40W multichannel speakers are more powerful, though the S90D's Object Tracking Sound Lite follows action on screen. A soundbar improves either.

Is the S90D worth stepping up to over the C2?

For most buyers, yes. You get a newer, brighter panel, 144Hz and an anti-reflection screen. The C2 makes sense if its value is clearly better for a 77-inch set.

Samsung S90D OLED 4K Smart TV vs LG C2 OLED evo TV (77")

The Samsung S90D is the newer set and the better pick for most people: a 2024 QD-OLED panel with four HDMI 2.1 ports at up to 144Hz, an anti-reflection screen and strong HDR brightness. The LG C2 is a 2022 OLED evo that still looks excellent and runs webOS, but it is older, tops out at 120Hz and has fewer gaming-friendly extras. Reviewers and owners praise both for deep blacks and wide viewing angles; the S90D is the one to step up to unless you find the C2 at a clear value advantage.

Choose the Samsung S90D if you want the newer panel, 144Hz gaming, an anti-reflection screen and the brightest OLED picture of the two.
Choose the LG C2 if you want a proven 77-inch OLED with webOS, AirPlay and HomeKit, and the older model's value suits you.
