Which is better for a living room?

The 65-inch A. At 8 to 10 feet, 65 inches fills the view where 55 inches looks small. Both have the same panel quality, so size is the only real difference.

Is the 65-inch worth the extra over the 55-inch?

At the November 3, 2026 prices they cost the same $1,399.99 at Best Buy, so the 65-inch is the better buy. If the 55-inch drops well below that, the gap becomes a real trade-off.

Which is better for gaming?

They are equal. Both do 4K at 120Hz, VRR up to 165Hz, G-Sync, FreeSync Premium and 0.1ms response, with 4 HDMI 2.1 ports.

Do both have Dolby Vision and Dolby Atmos?

Yes. Both support Dolby Vision, HDR10 and HLG, plus Dolby Atmos and Filmmaker Mode.

Neither has an edge on paper. Both use the same WOLED panel and α11 Gen3 chip, so lifespan depends on brightness settings and static content, not on size.

Will the price drop soon?

The 65-inch fell to $949.99 on November 3, 2026, from $1,399.99 on October 29. The 55-inch also hit $949.99 that day. Check the price history before you buy.
