Which is better for gaming?

Both run 120Hz with G-Sync and FreeSync Premium, so motion is smooth on either. The LG adds four HDMI ports, which helps if you keep a console, PC and soundbar connected at once.

Does the LG have Dolby Vision and the Samsung not?

Yes. The LG C6 supports Dolby Vision, HDR10 and HLG. The Samsung S85H lists HDR10 and HLG but no Dolby Vision, so Dolby Vision discs and streams play in HDR10 on it.

Which has better sound?

The Samsung lists Dolby Atmos, Object Tracking Sound Lite and Q-Symphony, which syncs with Samsung sound bars. LG owners report good built-in sound but also muffled dialogue at high volume.

Is the LG worth stepping up to over the Samsung?

Step up if you want Dolby Vision, a tuner and more HDMI inputs. Stay with the Samsung if a slim glare-free panel and sound bar pairing matter more.

Which is easier to wall mount?

The Samsung is lighter at 23.1 lb for the 48-inch and has a slim profile. LG owners say wall mounting took time due to size and weight; the C6 uses a 300 x 200 mm VESA pattern.

Samsung S85H OLED TV vs LG C6 OLED evo 48" 4K TV

Both are 48-inch 4K OLEDs at 120Hz with FreeSync Premium and G-Sync, so motion and black levels are close. The LG C6 adds Dolby Vision, four HDMI ports, a tuner and webOS, which suits movie watchers and anyone with a cable box. The Samsung S85H counters with Pantone-validated color, Q-Symphony with Samsung sound bars and a slim glare-free panel, and its owners rate it highly. Owners of both praise the picture; LG owners more often mention hard-to-hear dialogue and a fiddly remote, and one Samsung owner noted off-angle distortion on a wavy panel.

Choose the Samsung S85H if you want a slim, glare-free OLED that pairs cleanly with a Samsung sound bar and you mostly stream.
Choose the LG C6 if you watch Dolby Vision movies, need four HDMI inputs and a built-in tuner, or want Google Gemini and Copilot on the TV.
