This was my first OLED and I am very impressed; plus the screen size is perfect for our new home theater. This was definitely the "icing on the cake" for finishing up the home theater project/remodel. Best Buy was great to work with. I originally had a different kind of TV arrive and it was broken in the box, and Best Buy was awesome to work with on getting it sorted out. I ended up returning the broken TV and exchanged it for this one instead, and I am very happy. I'm impressed with the Best Buy staff on how they helped answer my questions and helped me with getting the other tv returned. Back to the TV review, this TV is very clear/sharp, has very black contrast and with the picture being so realistic while watching movies, it's almost like you can reach out and touch the object that you're watching; it's truly an amazing TV. We've been a fan of Samsung TVs for many years, in fact we have one Samsung TV that is 11 years old and still works, so we know we made the right decision to go with Samsung. I'm running my sound through a receiver for home surround sound, but while I was testing everything I just temporarily used the built-in speakers that come with the TV, and I'm very impressed with how good it sounds given how thin this TV is. Thank you again Best Buy, your customer service made this a very pleasant experience.

I’ve had the Samsung S84D Series 77-inch OLED TV set up in my living room for a while now, and I can honestly say it’s the best screen I’ve ever owned. Right out of the box, the picture quality blew me away. The OLED panel produces these incredibly deep blacks—movies look so lifelike, it’s kind of surreal! Colors pop off the screen, and thanks to the 4K resolution, everything is crisp whether I’m watching a blockbuster or just streaming YouTube. The Tizen operating system is a breeze to use. Switching between Netflix, Disney+, and the other built-in apps feels smooth and intuitive—plus, the voice assistant is actually helpful for finding content or controlling other smart devices around the house. If you’re into gaming like I am, this TV is a treat. It supports HDMI 2.1, variable refresh rate, and all that next-gen stuff, so playing on my PlayStation 5 feels unbelievably smooth. No lag, no motion blur, just pure immersive gameplay. That said, if you're all about HDR gaming, sometimes the brightness dips in really intense scenes, but it’s a minor thing unless you’re super picky. One thing I wish was better: the speakers. They’re okay for casual watching, but if you want a full-on cinematic experience, definitely add a soundbar or surround system. Also, this TV is heavy—don’t try lifting it alone! You'll want at least two people for setup. The overall design is stunning. It’s so thin and sleek, and it looks fantastic mounted on the wall. Even though it’s on the pricey side, I got mine during a sale and honestly, I think it’s worth every penny. The quality is top-notch, and it’s made my home theater setup feel complete. Pros: Stunning picture with amazing colors and deep blacks Super smooth gaming performance Easy-to-use smart features Gorgeous, slim design Cons: Built-in speakers could be better Heavy—moving it is a team sport If you're searching for a TV that nails picture quality and is packed with smart features, the Samsung S84D OLED deserves a spot in your home. I’d recommend it to anyone who wants the ultimate viewing experience.

The 77” Class S84D OLED Smart TV is a standout in both performance and design. From the moment it’s turned on, it’s clear this is a premium television built for true home theater enthusiasts. ⸻ Picture Quality The OLED panel delivers deep, true blacks and an exceptional contrast ratio that brings out incredible detail in both dark and bright scenes. Colors are vibrant and accurate, making movies, shows, and even games look lifelike and immersive. With 4K resolution and HDR support, the picture clarity is sharp, clean, and refined—everything you’d expect from a high-end OLED display. ⸻ Smart Features & Tizen OS Powered by Samsung’s Tizen operating system, the interface is smooth, intuitive, and responsive. App support is wide-ranging, including Netflix, Disney+, Prime Video, YouTube, and more. The built-in voice assistant makes it easy to control the TV, search for content, or even manage smart home devices—all hands-free. ⸻ Gaming and Performance For gamers, this TV is a dream. It supports HDMI 2.1, low input lag, and features like Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM), making it an excellent companion for next-gen consoles like the PS5 or Xbox Series X. Gameplay is fluid and responsive, with visuals that truly pop. ⸻ Design The ultra-thin profile and minimalist bezel make this 77” screen feel even larger and more cinematic. It blends beautifully into any modern space and can be wall-mounted for a clean, gallery-like look. ⸻ Audio While OLED TVs are known more for their picture than sound, the S84D Series holds its own. Built-in speakers provide clear dialogue and decent bass for everyday use. For those seeking a full cinematic experience, pairing it with a high-quality soundbar or surround system takes it to another level. ⸻ Pros • Stunning 4K OLED display with deep blacks and rich colors • Smooth and responsive Tizen smart platform • Excellent for gaming (HDMI 2.1, VRR, low input lag) • Sleek, modern design • Reliable voice assistant integration Cons • Built-in speakers are good, but not a replacement for a full audio setup • Premium pricing (but justified by performance) ⸻ Final Verdict The 77” S84D Series OLED Smart TV is a top-tier choice for anyone serious about picture quality and smart features. Whether you’re watching a blockbuster, streaming a series, or gaming, the experience is immersive and smooth from start to finish. If you’re looking to upgrade your home entertainment system, this TV is worth every dollar.
