This TV features full-array local dimming, meaning it controls brightness zone by zone for stunning contrast and deep blacks. That’s a massive step up from basic edge-lit panels, giving you true picture depth.
Input lag sits at just 10–13ms, so your button presses feel instant during fast-paced games. HDR10 and Dolby Vision support round out a feature set that punches well above its class for serious gamers and content lovers alike.
Build quality feels solid, though some users report occasional motion blur at standard 60Hz playback and glare issues in bright rooms.

- Full-array local dimming delivers superior contrast and black levels
- Strong HDR format support (HDR10, Dolby Vision) for vibrant highlights

The Samsung DU8000 is a straightforward 4K TV built for viewers who want basic picture quality without gaming frills. It suits anyone watching movies, sports, or everyday content in darker rooms where brightness demands stay low.
This TV uses a VA panel with edge LED backlighting and includes Samsung’s Crystal Processor 4K for upscaling standard content. The 178° viewing angles mean you can watch comfortably from the side, and Tizen OS keeps navigation smooth and simple.
Build quality feels standard—nothing premium, but solid enough for everyday use. Real-world performance shows the TV handles calm, non-gaming content well in dim lighting conditions.
However, brightness falls short in both SDR and HDR modes, leaving highlights looking flat and washed out. The lack of local dimming means contrast stays flat compared to zone-controlled competitors, and gaming features are essentially absent here.
Pros
- Wide 178° viewing angles for flexible seating positions
- Simple, intuitive Tizen operating system
- Basic 4K upscaling for standard content
- Reliable everyday performance in dark rooms
Cons
- Insufficient brightness in SDR and HDR content
- Edge LED backlighting delivers poor contrast and flat blacks
- No local dimming, gaming features, or HDMI 2.1 support
Head to Head: Key Differences
The TCL Q77K and Samsung DU8000 serve completely different audiences. The TCL targets gamers and performance enthusiasts, while the Samsung appeals to casual viewers seeking basic 4K content.
Contrast and brightness represent the biggest gap between these TVs. The TCL uses full-array local dimming, which means it controls hundreds of independent brightness zones across the screen.
The Samsung relies on edge LED backlighting, which offers no zone control and produces noticeably weaker contrast and dim highlights in HDR content.
Gaming capabilities heavily favor the TCL. It delivers 288Hz at 1080p and 144Hz at 4K with input lag between 10–13ms, making fast-paced games feel responsive and smooth.
The Samsung maxes out at 50/60Hz refresh rates with no gaming optimizations, so competitive play feels sluggish by comparison.
HDR performance differs significantly. The TCL supports HDR10 and Dolby Vision with brighter, more vibrant highlights thanks to superior backlighting.
The Samsung’s HDR content appears flat and washed out due to insufficient brightness in both SDR and HDR modes.
Viewing angles and everyday use slightly favor Samsung. Both TVs offer wide viewing angles, but the Samsung’s 178° rating works well for flexible seating in dark rooms.
The TCL occasionally shows motion blur at standard 60Hz playback and can display direct reflections under bright lighting.
The TCL Q77K excels at demanding tasks like gaming and HDR movies. The Samsung DU8000 works fine for basic 4K viewing in controlled lighting, but lacks the technology and features that make modern TV viewing truly impressive.
Which One Should You Buy
The TCL Q77K stands out as the overall winner in this comparison. It delivers superior contrast through full array local dimming, making dark scenes look rich and detailed.
Gamers benefit most from its HDMI 2.1 support, high refresh rates, and low input lag. These features make the Q77K a more capable and versatile television for everyday use.
The Samsung DU8000 still holds value, but it caters to a simpler viewing experience without advanced gaming perks.

TCL Q77K: Perfect for gamers and viewers who want strong contrast, smooth motion, and modern HDMI 2.1 connectivity.
