    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.

    Amazing brightness, detail, and response time.

    The tv is amazing. Extremely bright has very little to no issues with glare. The game mode is amazing allowing you to put a permanent dot in the center of the screen for better accuracy. It’s fast and responsive. My only complaint with the tv is the remote doesn’t have a simple input/source button. It also has a really cool split screen mode on the tv allowing you to enjoy separate content at the same time.

    Awesome Picture

    Love it! Great picture, easy to tune to the preference you want. It’s heavy but looks great mounted to the wall. Now we just need more content that streams 4k so I can take advantage of the picture. One note is the remote is tiny and I feel I will lose it at some point lol.
