Premium 85″ TCL C8K TV with Bang & Olufsen sound discounted by almost 50 thousand! It has 144 Hz and incredible brightness

When TCL launched its C8K series last May, the 85″ version was priced at 99,990 CZK. Over time, it dropped to 64,990 CZK, and now you can get it for 51,210 CZK with code ALZADNY15 – roughly half the original price. Compared to the cheaper C7K model, which we wrote about recently, the C8K is a significant step up in both picture and sound quality. And it’s precisely the combination of 2,880 dimming zones, 90W Bang & Olufsen sound, and native 144 Hz that makes this TV one of the most interesting offers in the large Mini LED model category.

Quick summary:
✅ Makes sense if you’re looking for a large premium screen with Mini LED backlighting, high brightness, and sound that doesn’t immediately require a soundbar.
⚠️ Consider if you have a smaller living room (recommended viewing distance is 3–4 meters)
💡 For 51,210 CZK, you get an 85″ TV with parameters for which you would pay significantly more from competitors – plus gifts worth over 5 thousand CZK.

Why the C8K is more interesting than cheaper TCL models

TCL offers more large TVs – but the C8K series differs from cheaper models in several key points. While, for example, the 75″ TCL T69C has only native 60 Hz and basic backlighting, the C8K offers a native 144Hz panel, 2,880 dimming zones, and All-domain Halo Control technology, which suppresses the halo effect around bright objects on a dark background. This is the main weakness of cheaper Mini LED TVs – and the C8K addresses it directly.

Furthermore, the CrystGlow WHVA panel offers a native contrast ratio of 7,000:1, which is a very solid value for LCD technology. The anti-reflective layer helps with glare, although one reviewer on Alza points out that the cover layer is plastic – not glass. This is a compromise TCL likely chose for lower weight.

Picture: 4K HDR Premium with support for everything

4K Ultra HD resolution (3840 × 2160) is complemented by support for virtually all HDR formats – HDR10, HDR10+, HLG, Dolby Vision, and Dolby Vision IQ. Additionally, IMAX Enhanced certification and Filmmaker Mode for purists who want the picture exactly as the director intended. Quantum Dot technology ensures a wide color gamut with over a billion shades.

The AiPQ Pro processor handles upscaling lower-resolution content, noise reduction, and color and contrast optimization. The designation 4K HDR Premium 5000 indicates peak brightness – the TV should achieve values significantly exceeding typical Mini LED models, which you’ll especially appreciate in glass-walled living rooms with direct daylight.

Gaming features: native 144 Hz and Game Master

For gamers, the C8K is very well equipped. Native 144Hz refresh rate in 4K resolution, support for HDMI 2.1 with VRR and ALLM, FreeSync Premium Pro, and Game Master mode with an improved game bar. TCL also adds a 288Hz Game Accelerator feature, which doubles the refresh rate using DLG (Dual Line Gate) technology – but this only works in Full HD resolution, not 4K. Four HDMI 2.1 ports mean you can connect a console, PC, soundbar, and set-top box simultaneously.

Sound: 90 W from Bang & Olufsen

And here, the C8K is significantly above average. Speakers with a total output of 90 W tuned by Bang & Olufsen with a built-in subwoofer, supporting Dolby Atmos and DTS:X. That’s 50 W more than the cheaper C7K model (which had 60 W and B&O tuning). For most TVs in this overview, we recommend buying a soundbar – with the C8K, it might not be necessary. The Multisound feature also allows simultaneous audio playback from the TV speakers and wireless headphones with individual volume settings.

Google TV and practical aspects

The Google TV system offers access to all important streaming services – Netflix, HBO Max, Disney+, Prime Video, Czech Oneplay, and SledováníTV. Voice control via Google Assistant, content sharing via Chromecast and Apple AirPlay 2, HbbTV 2.0.3 support for interactive digital broadcasting features. The stand is height-adjustable, VESA 600×500 for wall mounting. The design is bezel-less with a metallic finish.

When it doesn’t make sense

If you have a smaller living room where you sit closer than 3 meters from the screen, 85″ is unnecessarily large. In that case, it makes more sense to opt for a smaller diagonal with a better panel – for a similar price, you can get a 77″ OLED from LG. And if you primarily care about perfect blacks and infinite contrast (e.g., for watching movies in a darkened room), Mini LED still doesn’t reach the level of OLED – even with 2,880 zones. The TCL C8K, on the other hand, is an excellent choice for bright rooms, where OLED loses out due to lower SDR brightness.

Verdict: who it’s worth it for

The TCL 85C8K for 51,210 CZK is a TV for those who want a truly large screen with premium features but don’t want to pay for OLED or even more expensive Mini LED models from Samsung or LG. For a price that is almost half of its launch price, you get 2,880 dimming zones, native 144 Hz, four HDMI 2.1, 90 W sound from B&O, plus gifts worth over 5 thousand CZK (6 months of SledováníTV and an extended warranty). The compromises are clear – a plastic cover layer and occasional upscaling issues according to initial feedback. However, for regular movie watching, sports, and gaming, it’s a hard-to-beat offer at this price.
