QD Mini LED picture performance

The TCL 65C8K is a 65-inch 4K television using a quantum dot Mini LED panel. Its backlight has 1,680 independently controlled local dimming zones, allowing different parts of the screen to become brighter or darker. This is designed to improve contrast and reduce blooming around bright objects.

TCL rates the TV for 4,500 nits peak brightness and a 5,400:1 native contrast ratio. In the video, this combination produced deep blacks, strong shadow detail and bright HDR highlights. The high brightness is particularly useful in bright rooms and gives HDR effects such as flames and lasers considerable impact.

The quantum dot layer delivers wide, vibrant colours, while Dolby Vision IQ and TCL’s AIPQ engine adjust the picture to suit room lighting. Skin tones were described as natural, including on familiar programmes, with no obvious sunburnt or overly pale appearance. Overall, the picture was considered close to OLED-like in contrast, but brighter.

HDR format support

The 65C8K supports HDR10, HLG, HDR10+ and Dolby Vision IQ, so viewers are not limited to a single premium HDR format. The video noted that Dolby Vision content from Netflix and Apple TV Plus, along with HDR10+ content, played as expected.

Dolby Vision IQ uses a sensor to adapt the HDR image to the room. In brighter conditions it can increase shadow visibility, while in darker conditions it can reduce the intensity of highlights. This is intended to keep the picture consistent across different viewing environments.

Gaming features

The television has four HDMI 2.1 ports, allowing multiple consoles and a gaming PC to remain connected. It supports 4K at up to 144Hz and 2K at up to 288Hz with variable refresh rate. Console gaming at 4K and 120Hz was described as smooth and responsive, while VRR helped avoid screen tearing.

The C8K is FreeSync Premium Pro certified and includes a game bar overlay with information such as frames per second and VRR controls. Its brightness also benefits HDR gaming, making bright effects more prominent.

Smart TV, connectivity and audio

Google TV provides access to common streaming apps, recommendations and voice search. The TV also includes Wi-Fi 6, far-field Google Assistant support, Apple AirPlay and HomeKit. The software was generally responsive, although occasional lag spikes were noticed while navigating. Wired networking is available through a 1Gb Ethernet port, which was suggested for particularly large Plex files.

Audio is tuned in partnership with Bang & Olufsen and has a stated 90W output with dual subwoofers. The built-in system was found to offer clear dialogue, stronger action sound and reasonable music playback compared with typical TV speakers. It also supports virtual Dolby Atmos, Bluetooth 5.4 and Dolby Atmos pass-through over eARC.

Design and limitations

The TV has a near-bezel-less front, silver trim and a solid pedestal stand. Its side profile is still relatively chunky, although it was described as one of the slimmer Mini LED designs tested. Wall mounting improves its appearance.

The compact voice-enabled remote works with HDMI-CEC devices, but it does not have a backlight. This makes it harder to use in a dark room. The software could also be slightly faster in places.

TechManPat’s conclusion

In my view, the TCL 65C8K is one of the strongest value televisions I have seen in a long time. At the time of the video, it was on sale for just under $2,000 Australian dollars, and it combined near-OLED blacks, very high brightness, broad HDR support, serious gaming features and capable built-in audio. The unlit remote, chunky side profile and occasional software lag are genuine drawbacks, but I considered them minor compared with the overall performance. For anyone wanting flagship-level picture quality without paying OLED prices, I thought the C8K was a compelling option.
