The TCL Q77K is a gaming-first 4K TV available in sizes from 55″ to 85″. It pairs HDMI 2.1 support with impressive refresh rates—288Hz at 1080p and 144Hz at 4K—plus variable refresh rate technology for smooth, responsive gameplay.
This model shines for competitive gamers and fast-action fans. The input lag sits between 10–13ms, making it one of the snappier options in its class.
Full-array local dimming, HDR10, and Dolby Vision round out the feature set, giving you solid contrast and color depth for movies too.
Build quality feels solid for the price point. The display handles a wide viewing angle without dramatic color shift, and format support is strong across streaming apps and gaming consoles.
Real-world testing shows this TV delivers exactly what it promises: fast response times and low latency.
Picture quality draws mixed reactions—some users love it, while others find it slightly underwhelming compared to premium rivals. Motion handling at 60Hz can introduce blur in certain scenes, and the glossy screen surface picks up reflections in bright rooms.
Pros
- Excellent gaming performance with 10–13ms input lag and 144Hz @ 4K
- High refresh rates (288Hz @ 1080p) for ultra-smooth gameplay
- Full-array local dimming with HDR10 and Dolby Vision support

The TCL Q672 is a massive 98″ 4K QLED TV built for viewers who want cinema-scale entertainment in their home. This model prioritizes screen real estate and picture quality over gaming specs, making it ideal for movie lovers and casual streamers.
The standout feature is its Quantum Dot technology, which delivers rich, vibrant colors across a wide brightness range. The High Brightness+ LED backlight ensures excellent visibility even in bright rooms, giving you a sharp, clear image from almost any angle.
Build quality feels solid and reliable for everyday use. The TV handles standard streaming, sports, and movies with impressive clarity and color depth, thanks to its 4K resolution and QLED panel.
Real-world performance shows this TV excels at picture quality and size value. The 120Hz native panel with 144Hz VRR support is adequate for casual gaming, though it won’t match the gaming-focused Q77K’s speed credentials.
Pros
- Massive 98″ screen option for immersive viewing
- Quantum Dot technology delivers vibrant, lifelike colors
- High Brightness+ backlight performs well in lit rooms
- Strong picture quality across movies and streaming content
Cons
- Lower refresh rate ceiling (120Hz native) limits competitive gaming appeal
- Limited model size options compared to competitor ranges
- VRR support doesn’t match the Q77K’s gaming-level responsiveness
Head to Head: Key Differences
