Q: What is the panel? Is it qd oled? If not, what is it?
A: OLED....the mini LED QLED looked better (for $1000 more) but only in 65'
Q: How long is this Tv on sale
A: undefined
A: Yes!!
A: Hi Gus, Thanks for your answer. I was concerned about the 60Hz from the avr compared to the TV’s 120Hz. Will the avr's speed affect watching live sports? I’m used to my plasma's 600Hz refresh time. Should I run a separate HDMI cable from my dvr to the other HDMI 2.1 port on the XR8B for live sports at 120Hz? Thanks, Jim
Q: Is this TV brighter than the Sony x950H in SDR? I mainly watch sports in a bright room.
A: Hi cusefan82, Thanks for your question! The X950H uses Full Array LED technology. The new BRAVIA XR8B OLED TV, however, features a more advanced processor and superior picture quality. Its perfect blacks and incredible contrast create a more impactful and lifelike image, making it the better choice for an exceptional viewing experience. Thanks for choosing Sony. Best regards, Eliab
Q: I have a 2020 Sony ah8 oled will this xr8b oled be brighter than my television?
A: YES! Sony, in the last several years, has significantly increased the brightness(nits quotient)factor of ALL their OLED & Mini-LED TV's. This OLED will be very much brighter in any room.
A: Hi Tommy, thank you for your question! The Sony - 77" class BRAVIA XR8B is essentially the same as the Sony - BRAVIA 8, with a few differences that are mostly related to features. The XR8B does not include the Sony Pictures Core credits or promotional package. It also lacks the XR Contrast Booster feature that intelligently adjusts the brightness in both bright and dark areas. Other than that, they both offer the same OLED panel and 4K resolution, combined with the XR Processor, for an immersive and top-notch viewing experience. We hope this answers your question, and thank you for considering Sony products! Best regards, Dominick

Amazing. Crisp clear photo and sound.
Picture is crystal clear. The sound is amazing if you don’t have a sound bar. I had a Samsung Curve before making this purchase, and this tv has exceeded my expectations. The brightness and sound will even adjust to where you’re sitting in the room. Everyone wants to come over to our house to watch football or a movie on the new “theater”

Worthy upgrade
I recently purchased the 77-inch Sony Bravia TV, and I couldn't be happier with it. The build quality is outstanding — solid, sleek, and clearly made with attention to detail. The display is stunning with vibrant colors, deep blacks, and sharp clarity that really brings content to life. What I love most is how user-friendly the interface is. Navigating through apps and settings is smooth and intuitive, making the whole experience enjoyable right out of the box. Paired with my Sony soundbar, the audio-visual experience is incredible — like having a mini theater at home. I've been a loyal Sony user since 1994. Based on that experience, I’m confident this new Bravia will be just as reliable and long-lasting. Highly recommended for anyone looking for a premium home entertainment upgrade!
