Updated to include the XR77A80K, as well as clarifications on settings. This XR65A80K I purchased was to replace an XR65X950H - the 950H is a very competent TV, and is still in use in a bedroom, but even as good as it is with its local dimming, the idea of zero blooming appealed to me. Fortunately, I have my oldest son's 55" LG C2 for a direct comparison, and while the C2 is slightly brighter and a better choice for next gen gaming, I felt the A80K was a better choice for my viewing habits, as most of my use is for movies, occasional YouTube browsing and every now and then, Nintendo Switch for retro games. After over a month to wring the Sony out on everything from 480 material ranging all the way up to 4K UHD Blu-rays, I can say that, as usual, Sony has done some awesome work here. Firstly, much has been made of OLED's shortcomings in moderately lit rooms - I'll make this point early, this panel is as capable as the Bravia 65X950H it replaced. Yes, specular highlights are brighter (1100+ nits for the 950 vs ~700 nits for the A80K), but those numbers only tell part of the story. With 8 million plus self lighting organic light emitting diodes, the blacks are perfect, and the brightness of those specular highlights are far more clearly defined. Yes, if you have a room flooded with sunlight, OLED isn't going to overcome that, but in a room moderately lit by sun, like mine, it's more than capable. Nighttime viewing is exceptional. The good: *Infinite contrast due to OLED technology. The inky blacks are only part of the story here, the clear distinction of a specular highlight against a far dimmer area create a far more enjoyable movie experience. *Out of the box color accuracy is amazing. First things first, on this and nearly every TV, Power Saving needs to be turned off. Picture Mode should be set to Custom, and in HDR, Gradation Preferred should be enabled for HDR10 and off for Dolby Vision. Only change I made to color itself was to slightly reduce the bias on the green sub pixels and slightly boost overall color saturation, the latter of which is something I've done on nearly every TV I've owned. *Processing. While I generally leave any additional video noise reduction and motion processing off, the few times I've felt the need to use any of them, they've been adjustable enough to add just what I wanted without the source material losing its sharpness or inducing soap opera effect. *Upscaling. As per usual, Sony's processing is second to none, although admittedly, LG has definitely closed the gap with the C2. Still, Sony has a visible edge here. *Sound. Although I use a Dolby Atmos/DTS X soundbar with surround speakers, the sound from the TV itself was surprisingly good. Since the panel is actually a speaker, the soundstage is pretty impressive - impressive enough to likely satisfy many people. *Operating temperature. I'd normally leave this out, but I honestly cannot believe how much cooler this thing runs when compared to an LED backlit LCD panel. I foresee this being a huge bonus this summer. *Lack of "black crushing": This is probably the biggest difference between the A80K and the C2 as far as picture quality. Details in dark scenes are clearly visible on the Sony, whereas they sometimes get lost on the C2. The "it could be better": *Brightness. This is really nit picking (no pun intended), but given that the A80K uses the same panel as the C2, yet is not quite as bright as somewhat of a mystery to me. To be honest, I can't see a definitive difference between the two, but it's worth mentioning. The Bad: *Only two HDMI 2.1 inputs, one of which is the same port used for a soundbar or receiver. To be fair, unless you're into next gen (PS5/Xbox X) gaming and have both consoles, this isn't going to be an issue, but a TV of this caliber should have four 2.1 inputs. *Potential for panel burn in. OLED technology has come a long way in the last decade, but the potential is still there for permanent burn in on individual pixels. If you watch a ton of TV (CNN with their bright white/red logo is a perfect example) that has a static logo, OLED probably shouldn't be on your want list, at least not yet. *Sustained bright picture will auto dim to protect the panel. While I've yet to experience this in anything other than intentionally trying to induce it, content with relatively bright areas over the majority of the panel, like ice hockey games, will activate auto dimming. *Dolby Vision. Please Sony, fix this. DV Dark is so out of whack that it's not even funny. While DV Bright can be made to look perfect as a DV Dark alternative, we deserve better. You did it on the A95K and LG's is great on their OLEDs, so we know it's possible. Remote: I get it, this isn't their flagship OLED, but it should come with the backlit remote. Movies and TV shows are this TV's strong points, and is particularly impressive with 4K High Dynamic Range/Dolby Vision content, both with hard copy and the built-in Google TV operating system. If sports (especially hockey) and/or the majority of your content has static logos, I'd probably stick with an LED backlit LCD TV. In closing, I did also consider the Sony A95K, the Samsung S95B and the LG C2 and G2. I passed on the Sony and Samsung because QD OLED is in its infancy, with a lot of long term questions about both burn in and longevity. The G2 lost out mostly because of the extra cost of a table top stand (wall mounting is not an option in my case). The A80K won over the C2 because of slightly better upscaling, the ability to pass DTS audio and the C2 having some problems with black crush. Since I first wrote this review, I've upgraded to the 77" version of the A80K, and everything still applies. I have changed a few things on settings that slipped my mind when I originally submitted the review.
