The TCL Q77K is a feature-packed 4K gaming TV that brings high-end performance to a wide range of screen sizes (55″ to 98″). It combines full-array local dimming, dual HDR formats (HDR10 and Dolby Vision), and HDMI 2.1 connectivity to deliver sharp contrast and smooth gaming action.
This model shines for competitive gamers and console enthusiasts. It hits 10–13ms input lag and supports up to 288Hz at 1080p or 144Hz at 4K, making fast-paced titles feel responsive and fluid.
The build quality feels solid, with sturdy stands and well-integrated connections.
Real-world viewing shows strong motion handling and decent side angles for group watching. The full-array dimming system produces deep blacks and bright highlights without blooming, which elevates everything from sports to movies.
A glossy screen surface can create mirror-like reflections in bright rooms, and some users report motion blur at standard 60Hz playback (though this remains debated among owners).

The Samsung Crystal UHD is a straightforward 4K TV built for viewers who want basic picture clarity without extra frills. It works best for people in smaller spaces or those stepping into 4K viewing for the first time.
This model stands out with its slim profile and clean design. The Color Booster technology adds punch to bright scenes, and Gaming Hub integration lets you stream games directly without extra devices.
Build quality is solid and understated. The slim frame fits neatly into tight spaces, and setup takes just minutes.
Real-world viewing shows crisp 4K detail on movies and shows. However, contrast levels stay modest compared to premium models, and the picture lacks the depth that local dimming brings to darker scenes.

- Basic 4K clarity looks sharp on standard content
- Gaming Hub built-in for instant game streaming
- Simple setup and straightforward controls
Cons
- Entry-level contrast and black levels

Head to Head: Key Differences
The TCL Q77K and Samsung Crystal UHD take fundamentally different approaches to 4K television. TCL focuses on gaming performance and picture depth, while Samsung prioritizes simplicity and clean aesthetics.
Gaming responsiveness separates these two models most clearly. The Q77K delivers HDMI 2.1 connectivity and input lag between 10–13ms, making it ideal for fast-paced console games.
The Crystal UHD maxes out at 120Hz with standard HDMI, which works fine for casual gaming but won’t satisfy competitive players.
Contrast and black levels show another major gap. The Q77K uses full array local dimming to independently control backlight zones, producing deep blacks and punchy highlights.
The Crystal UHD relies on basic edge lighting, resulting in washed out shadows and less dimensional images.
Motion handling differs too. The Q77K processes motion smoothly at high refresh rates, reducing judder during fast scenes.
The Crystal UHD handles standard 60Hz content adequately but lacks the motion fluidity of higher refresh rate displays.
Design and setup favor the Samsung. Its slim profile fits tight spaces better, and the minimalist design appeals to clean living rooms.
The Q77K has a glossy screen that reflects room lights, while the Crystal UHD uses a more neutral finish.
HDR format support matters for movie fans. The Q77K supports both HDR10 and Dolby Vision, expanding your content options.
The Crystal UHD offers basic HDR support without the Dolby Vision layer.
Choose the Q77K if you game regularly or want superior picture depth. Pick the Crystal UHD if you prioritize a slim footprint and straightforward 4K viewing without gaming demands.
Which One Should You Buy
The TCL Q77K stands out as the overall winner in this matchup. It packs full-array local dimming, HDMI 2.1, and higher refresh rates into one package.
These features give it a clear edge in picture quality and gaming performance. The Samsung Crystal UHD simply cannot match this level of technology.
If you want a screen that handles fast action and rich contrast with ease, the Q77K delivers. It offers noticeably better all-round performance.
Best for each buyer – TCL Q77K: Great for gamers and buyers who want advanced HDR, local dimming, and high refresh rates. – Samsung Crystal UHD: Suited for buyers who want basic 4K viewing with a slim design for space-constrained setups.
