When I decided to upgrade my living room setup, two TVs stood out: TCL C8K and TCL C7K. After spending several weeks using both, I can confidently break down their real-world performance, not just specs. Here’s everything I discovered while testing both Mini-LED TVs side by side.
Quick Comparison Table 📊
| Feature | TCL C8K | TCL C7K |
|---|---|---|
| Panel Type | Mini-LED QLED | Mini-LED QLED |
| Peak Brightness | ~2,000 nits | ~1,500 nits |
| Local Dimming Zones | 2,300+ | 500+ |
| HDMI 2.1 Ports | 4 | 4 |
| Max Refresh Rate | 144Hz | 144Hz |
| Smart Platform | Google TV | Google TV |
| Audio System | 2.1.2 Dolby Atmos | 2.1 Dolby Atmos |
🔆 Brightness & HDR
- TCL C7K is bright enough for most rooms, but struggles a bit with specular HDR highlights.
- TCL C8K shines in HDR – literally. With over 2000 nits peak brightness and far more dimming zones, it delivers an OLED-like contrast with Mini-LED punch.
🎯 Watching „Avatar 2” on the C8K was eye-popping — underwater scenes were immersive and had zero blooming around subtitles.
🎮 Gaming Experience
Both TVs support 4K at 144Hz, VRR, ALLM, and FreeSync. However:
- TCL C8K has more aggressive HDR tone mapping in games like Cyberpunk 2077, with better shadow detail.
- TCL C7K is great for casual gamers, but HDR effects don’t pop as much.
🕹️ Input lag was virtually identical (~6ms).
🧠 Smart Features
Both run Google TV: smooth, modern, with excellent app support and Google Assistant built-in. Navigation was slightly faster on the C8K, likely due to a better processor.
✅ Supports Netflix, Prime Video, Disney+, YouTube.
🔊 Sound Quality
- TCL C7K is decent with clear dialogue, but lacks bass.
- TCL C8K includes 2.1.2 Dolby Atmos with virtual surround — more immersive in movies.
🖼️ Design & Build
- C7K: Simple and elegant, with a narrow bezel.
- C8K: Ultra-slim, more premium materials, looks stunning wall-mounted.
💰 Price & Value
- TCL C7K is one of the best value Mini-LED TVs this year.
- TCL C8K costs more, but the performance bump in HDR, contrast, and sound is substantial.
