Which is better for a bright living room?

The LG C6. Its OLED evo panel is brighter than the Samsung S84H's standard OLED panel, and it adds Dolby Vision, which helps with HDR highlights in daylight.

Is the 65-inch Samsung worth $50 more than the 55-inch LG?

Only if screen size is your priority. At $999.99 versus $949.99 as of November 5, 2026, you pay about $50 for 10 more inches but give up brightness, Dolby Vision and two HDMI ports.

Which is better for gaming?

The LG C6. Both run 120Hz, but the C6 adds VRR rated up to 165Hz and has 4 HDMI ports, which matters if you connect a console, PC and soundbar.

Neither has a published lifespan advantage. Both are OLED sets, so burn-in risk from static logos applies to each; the LG's larger owner base (6,600 ratings) gives more real-world reliability data.

Does the Samsung support Dolby Vision?

No. The S84H handles HDR10 and HLG. Dolby Vision content plays in base HDR, while the LG C6 displays it natively.

Which has the steadier price?

The Samsung, at $999.99 since October 30, 2026. The LG moved between $949.99 and $1,029.99 in early November, so check its price history before buying.
