Deal pricing and availability subject to change after time of publication.If youve been holding out for a deal on a big-screen OLED TV, the Samsung 77-inch S84D might be worth a look. Its currently marked down to $1,599.99 at Best Buythats less than half its usual $3,299 price tag. The S84D benefits from OLEDs self-lit pixel technology, meaning its contrast is virtually unbeatable. Bright highlights pop against pitch-black backgrounds, perfect for dimly lit rooms or late-night movie marathons. And thanks to its lack of local dimming, theres no annoying blooming effect where bright spots bleed into dark areas. That said, while its HDR brightness is decent, its not the most dazzling OLED out there. Large bright scenes can look dimmer due to its aggressive Automatic Brightness Limiter (ABL), and HDR gaming takes a hit in Game Mode because of this.Still, for gamers, theres a lot to like. With support for 4K at 120Hz, VRR (Variable Refresh Rate), and super-low input lag, its great for the PS5, Xbox Series, or a high-end gaming PC. The lack of Dolby Vision support might disappoint some, but its performance with other HDR formats holds up. If youre into fast-paced games, its near-instantaneous response time promises clear motion with almost no blur. For everyday use, the TV excels in upscaling lower-resolution content like older DVDs or streams and its excellent viewing angles make it great for group watch parties. Additionally, the S84Ds reflection handling is said to really minimize glare (even in well-lit rooms).This smart TV features the 2024 version of Tizen OS, known for being quick and user-friendly. It offers a wide range of apps, making it simple to find your go-to streaming services. You can also cast content directly from your phone or play videos via a USB stick. The TV supports Bixby and Alexa voice assistants, with a remote that includes a built-in microphone for easy voice commandswhether youre launching apps, switching inputs, checking the weather, or adjusting brightness. However, when it comes to sound, the S84D reportedly falls short. While dialogue is clear at moderate volumes, the audio quality diminishes as you turn it up, and the lack of meaningful bass leaves action scenes or music sounding a bit flat.
