Which has the better picture?

The BRAVIA 8 II. Its QD-OLED panel adds quantum dot color and higher brightness, and it supports Dolby Vision. The 77-inch BRAVIA 8 is still a strong OLED, just a step behind on color volume and peak brightness.

Is the bigger 77-inch worth choosing over the 65-inch?

Only if distance drives it. At 9 feet or more, the 77-inch fills the view and its 56W screen speaker helps. In a smaller room, the 65-inch 8 II gives the better image for the same wall space.

Which is better for gaming?

Both run 120 Hz with VRR and HDMI 2.1, so both suit consoles. The 8 II's brighter QD-OLED panel holds up better in a bright room during daytime play.

Neither has a published lifespan edge. OLED panels can dim over years of heavy static content, and QD-OLED is newer, so long-term data is thinner. Buy for picture and size, not durability.

Do I need a soundbar with either?

The 77-inch BRAVIA 8 is the stronger stand-alone option with its 56W screen speaker. The 65-inch 8 II supports Dolby Atmos and DTS:X, but a soundbar still adds real bass to both.

Which is easier to wall mount?

The 65-inch 8 II, at about 50.5 lb versus about 71 lb for the 77-inch. Both use standard VESA mounting, but the lighter set is a simpler two-person job.

Sony BRAVIA 8 77" OLED TV vs Sony BRAVIA 8 II 65" QD-OLED TV

The BRAVIA 8 II is the better TV on picture: QD-OLED adds quantum dot color and Sony's highest OLED brightness, and owners rate it higher. The 77-inch BRAVIA 8 wins on size and on sound, since its screen doubles as the speaker with 56W of output. Buy the 65-inch 8 II for the best image in a normal room; buy the 77-inch 8 if you sit far back and want the bigger picture.

Choose the Sony BRAVIA 8 77-inch if you sit more than about 9 feet away and want the largest OLED picture with strong built-in sound.
Choose the Sony BRAVIA 8 II 65-inch if picture quality matters most and your seating is close enough for a 65-inch screen.
