Sony BRAVIA XR8B 77" OLED TV vs Sony BRAVIA 8 II 65" QD-OLED TV

Both are 2025 Sony OLEDs with Google TV, 120 Hz panels and four HDMI ports, so the real decision is panel type and size. The XR8B is a 77-inch WOLED set: bigger, with the deeper blacks and wide viewing angles OLED is known for, and it rates 4.4 from a larger pool of 135 owners. The BRAVIA 8 II is a 65-inch QD-OLED with Dolby Vision and DTS support and Sony's brightest OLED panel, which suits a bright room or a viewer who wants the most color volume. Pick by room size and light first; both are well-reviewed, and neither is a step down in build.

  • Choose the Sony XR8B if you sit far from the screen and want the largest OLED picture, with Dolby Vision not on your must-have list.
  • Choose the Sony BRAVIA 8 II if your room is bright or your seat is close, and you want QD-OLED color plus Dolby Vision and DTS support.

Questions and answers

Which is better for a bright living room?
The BRAVIA 8 II. Its QD-OLED panel is Sony's brightest OLED and holds color better in daylight. The XR8B is fine in a dim room but gives up some punch in strong light.
Is the 77-inch worth stepping up to over the 65-inch?
If your seating distance is roughly 9 feet or more, yes. The extra 12 inches of diagonal makes a clear difference at that range. In a small room the 65-inch QD-OLED looks sharper and brighter.
Which has better picture quality?
The BRAVIA 8 II wins on color volume, brightness and Dolby Vision. The XR8B wins on size and, for many viewers, on black-level uniformity. Both use the same Google TV platform.
Do both support Dolby Vision and DTS?
No. The BRAVIA 8 II lists Dolby Vision and DTS:X. The XR8B lists HDR10 with Auto HDR Tone Mapping and Dolby Atmos only.
Which is better for gaming?
Both run 120 Hz with four HDMI ports, so they are close. The BRAVIA 8 II adds Dolby Vision, which some consoles use, while the XR8B gives you a larger screen for split-screen play.
Which lasts longer?
Neither has a published lifespan edge. Both are 2025 OLED sets, and OLED panels age with brightness over years. Buy the size and panel type that fit your room rather than betting on longevity.
