What Buyers Say
Users are consistently blown away by the picture quality, especially the deep blacks and vibrant colors that OLED is known for, with many noting how well it handles HDR content even in brighter rooms. The gaming features, like the 144Hz refresh rate and low response time, are frequently praised for making gameplay incredibly smooth. However, the smart TV experience with WebOS often draws criticism for being slow and having too many ads, leading some to immediately connect an external streaming device. The remote control also feels like a step down in quality for a TV in this price range.
“Honestly, the picture is INSANE, like, perfect blacks and everything, but the remote feels like it came from a dollar store and WebOS is just a billboard for ads. I just use my Apple TV now, problem solved.”
Common Praise
- Perfect black levels and infinite contrast make dark scenes incredibly detailed
- Brightness Booster makes HDR content pop even in well-lit rooms

- Gaming is silky smooth and responsive due to the 0.1ms response time and 144Hz VRR
- Dolby Vision and Dolby Atmos create an immersive cinematic experience
- Four HDMI 2.1 ports provide ample connectivity for multiple high-end devices
Common Complaints

Ownership Tips

- The TV's gaming features are truly a standout, making it a primary display for next-gen consoles and PC gaming

Buying Guide
When buying an OLED TV, you're investing in picture quality where each pixel lights itself, meaning you get perfect blacks and incredible contrast that LED TVs can't match. Pay attention to the processor, as it handles upscaling lower-resolution content to 4K and impacts overall picture smoothness. For gamers, a high refresh rate and low response time are crucial for fluid, tear-free gameplay.
OLED Panel
Unlike traditional LED TVs that use a backlight, OLED pixels generate their own light. This means when a pixel needs to be black, it simply turns off, resulting in 'perfect black' and infinite contrast, making images incredibly lifelike and detailed, especially in dark scenes.
Refresh Rate (120Hz/144Hz VRR)
This number tells you how many times per second the screen can draw a new image. A 120Hz native refresh rate means smoother motion for movies and sports. For gamers, 144Hz with Variable Refresh Rate (VRR) means the TV can sync its refresh rate with your game console or PC, eliminating screen tearing and stuttering for a much more fluid experience.
Alpha 9 AI Processor Gen8
Think of this as the TV's brain. A powerful processor like the Alpha 9 Gen8 uses artificial intelligence to analyze and optimize every frame, enhancing picture quality by upscaling lower-resolution content to near 4K, improving color accuracy, and making motion look smoother. It's what makes everything you watch look its best.
Alternatives
If you need even higher peak brightness for extremely sunny rooms, look for OLED models with more advanced brightness-boosting technologies. If you want a simpler, ad-free smart TV experience, consider models that run a different operating system or plan to use a dedicated external streaming device.
