The TCL Q77K is a 4K gaming TV built for players who want smooth motion and deep blacks without compromise. It pairs full-array local dimming with 242 zones on the 65″ model to crush contrast in dark scenes.
This set delivers ultra-low input lag between 10–13ms, making it a serious contender for competitive gaming. You also get HDMI 2.1, VRR support, and the muscle to hit 288Hz at 1080p or 144Hz at 4K for buttery-smooth gameplay.
The TCL handles HDR10 and Dolby Vision, so streaming content and next-gen games look vibrant and detailed. Build quality feels solid, and the dimming zones give you control that rivals much pricier panels.
Real-world use shows this TV excels at motion performance and gaming responsiveness. The main trade-off is minor motion blur at 60Hz and occasional blooming in extremely dark scenes—minor issues for the performance you get.
Pros – Ultra-low input lag (10–13ms) crushes response time for competitive gaming – 242 dimming zones deliver exceptional black levels and contrast – Smooth 144Hz @ 4K and 288Hz @ 1080p motion handling – Fantastic HDR format support with Dolby Vision
Cons – Motion blur appears at standard 60Hz refresh rates – Blooming and halo effects visible in very dark scenes – Fewer dimming zones on smaller screen sizes

Head to Head: Key Differences
The TCL Q77K and Samsung QLED take different approaches to picture quality. TCL focuses on contrast and black levels, while Samsung emphasizes brightness and color vibrancy.
Dimming zones make the biggest practical difference. The TCL Q77K uses 242 dimming zones on its 65 inch model, compared to Samsung’s 96 zones. This means TCL delivers deeper blacks and more precise light control in dark scenes.
Gaming performance heavily favors TCL. Input lag sits between 10–13ms on the TCL, giving competitive gamers a real advantage. Samsung offers solid gaming features, but doesn’t match this responsiveness.
Motion handling differs noticeably. The TCL excels at smooth motion and gaming fluidity, though some users notice motion blur at standard 60Hz refresh rates. Samsung handles motion well too, yet doesn’t reach the same level of smoothness.
Brightness and room environment matter. Samsung QLED shines in bright rooms where its high brightness cuts through glare and window reflections. TCL performs better in controlled lighting where its contrast advantage becomes apparent.
Reliability shows real differences. Samsung users report occasional dead pixels and edge heat generation during long viewing sessions. TCL owners generally experience fewer quality control issues overall.
HDR and color support run similarly. Both TVs handle HDR10 and Dolby Vision, delivering vibrant streaming content and next-gen game visuals. Quantum Dot technology on Samsung produces rich, saturated colors that stand out.
Dark scene performance reveals the gap. TCL’s superior dimming zones prevent blooming and halo effects in dark content. Samsung can show some clouding in these same scenes due to fewer dimming zones.
Choose TCL for gaming, contrast, and dark room viewing. Choose Samsung for bright environments and peak brightness output.
Which One Should You Buy
The TCL Q77K takes the win in this matchup. It delivers superior dimming performance with 242 zones compared to Samsung’s 96 zones.
This gives the TCL deeper black levels and better contrast overall. It also has lower input lag and fewer reported quality control issues.
For most buyers, the TCL Q77K is the smarter pick. It performs well across gaming, movies, and everyday viewing.
