Which is better for a bright living room?

The Samsung S90H. Its Glare Free coating is new to the S90 series and cuts reflections from windows and overhead lights. The LG C6 uses a standard anti-reflective finish.

Is the LG C6 worth the extra $252?

Only if Dolby Vision and Dolby Atmos matter to you. Both sets run 165Hz OLED panels with similar AI processors, so the picture gap is small. The Samsung is the better value at $897.99.

Which is better for gaming?

They are close. Both offer 165Hz VRR, 0.1ms-class response and four HDMI inputs. The LG adds G-Sync and FreeSync Premium certification, which helps if you use a PC.

Do both support Dolby Vision?

No. The LG C6 lists Dolby Vision and Dolby Atmos. The Samsung S90H lists OLED HDR and HDR10+ instead, so Dolby Vision content plays in HDR10+ or HDR10.

Which has more HDMI and USB ports?

Both have 4 HDMI inputs. The Samsung has 3 USB ports versus 2 on the LG, a small edge if you plug in drives or accessories.

Neither maker publishes a panel lifespan figure. Both use OLED with pixel-level dimming and include burn-in mitigation features, so expected life is similar.
