A Cinematic Revolution in My Bedroom
Setting up the Samsung S90D OLED 77” was a breeze—everything from unboxing to installation was seamless, but nothing could have prepared me for the experience that followed. As soon as I powered on the screen and queued up Napoleon Dynamite, I was utterly transported. The sheer size of the display, paired with its breathtaking OLED clarity, made me feel as though I had stepped into an IMAX theater, right in my own home. Watching the talent show scene, it was as if I was sitting front row—every detail, every subtle nuance of Napoleon’s awkward dance moves felt larger than life. The realism of the colors and the depth of the picture were nothing short of mesmerizing. I wasn’t just watching a movie; I was living it. The way the screen rendered every vibrant, quirky moment of the film felt so immersive that I nearly reached out to high-five Napoleon as he celebrated his iconic performance. This TV is not just a display—it’s a gateway to experiences so rich, so vivid, that they transcend the boundaries of your living room. Whether you’re a cinephile or just looking to elevate your home entertainment, the Samsung S90D OLED 77” will transform your viewing experience into something truly cinematic, unforgettable, and simply jaw-dropping.

Absolutely Stunning! 77’ Highly recommend
I did a ton of research and it was between Sony A80L, LG G3 and Samsung S90D. I went in to the store and saw all 3, played different video SDR, HD, HDR10+ etc in the end I went with the Samsung s90d 77 inch. The 77 has the QD-OLED panel, when I finally got it mounted and dialed in, I watched Furiosa. To say I was absolutely stunned by the picture quality is an understatement. This is prob the best TV I’ve ever watched. I’ve had it just over a week and not a day goes by me, or someone in my family mention how good the picture is on this OLED. If you’re on the fence, get off and get the QD-OLED panel which comes in 55 inch, 65 inch and 77 inch. Also you can verify by the last few of the model # as long as it ends in last 4 of model number FXZA. The WOLED had last 4 of EXZA. In US the 42.48 and 83 are WOLED and 55,65,77 are qd oled. The other sizes are WOLED. If you get the QD-OLED panel you won’t be disappointed.

Great family TV.
The ambience feature doesn’t allow you to use one particular picture and is constantly scrolling. For instance, the one we picked was a fireplace and we wanted that in the background, but it kept scrolling through different things standby or at rest screen can’t be customized and is always some stupid red dots. Quality of the television and the OLED system is incredible.
