TCL Q6C

The Q6C brings QD-Mini-LED, 144 Hz, and an Onkyo sound system into a price range where none of these features are typically standard. netzwelt gives it a rating of 2.1, while testberichte.de scores it at 1.5. The street price is around 450 euros for 55 inches.

Positioning and Target Audience

The Q6C is the all-rounder of the test field: bright enough for daylight, fast enough for consoles, loud enough without a soundbar. Those who only need one of these features can find better options elsewhere – for those who want all three, this offers the best value.

Picture and Panel

574 nits peak brightness is clearly sufficient for visible HDR, and the QD-Mini-LED backlight with local dimming produces an unusually good contrast for the price. The color deviation stands at a Delta-E of 2.0. The weak point is the transitions: in scenes with extreme light-dark contrasts, the dimming zones are visibly flickering. As with all VA panels, color fidelity drops off from the side.

Gaming and Connections

• 4K at 144 Hz
• HDMI 2.1, VRR, ALLM
• Input lag of 17 milliseconds
• Triple tuner, CI+

For PS5 and Xbox Series X, the features are complete, and the 144 Hz benefit PC gamers.

Sound and Operating System

Onkyo provides two additional bass speakers – the Q6C sounds stronger than most flat-screen TVs in this price range and manages well for TV and series without a soundbar. Google TV runs smoothly and brings Chromecast along with the full app selection, plus the free TCL Channels.

What’s Missing

The plastic frame appears basic, and for the largest diagonals from 85 inches, TCL switches to a matte screen – the 55-inch variant does not have this. Dolby Vision, HDR10+, and HLG are, however, all supported.

Conclusion and Price-Performance Ratio

Around 450 euros for 55 inches (as of August 2026), energy efficiency class F, available from 50 to 98 inches. The Q6C is the most balanced device under 500 euros: it does not have top marks, but also no real weaknesses. Those wanting more brightness pay around 100 euros extra for the Hisense U7Q Pro – those wanting more contrast should opt for the Sharp.
