Which is better for a bright living room?

The TCL QM6K. Its Mini LED backlight reaches higher brightness and holds contrast better with daylight or lamps on. The LG C5 wins in a dim room.

Which is better for gaming?

The LG C5 for consoles, thanks to four HDMI 2.1 ports, 4K 120Hz, VRR and a 0.1ms response time. The TCL QM6K has the higher 144Hz native panel and VRR up to 288, which suits fast PC play.

Is the LG C5 worth the extra money?

If you watch movies in a dark room or want the best console gaming picture, yes. If you mostly watch sports and streaming in a bright room, the TCL at $477.99 at ABC Warehouse as of November 3, 2026 is the better value.

Which has better sound out of the box?

The TCL QM6K has an ONKYO 2.1 system with a built-in subwoofer at 40W. The LG C5 has a 2.2 channel 40W system. Both benefit from a soundbar for movies.

The TCL has no organic panel, so no burn-in risk from static logos or news tickers. The LG C5's OLED panel can retain images with heavy static content, though normal mixed viewing is low risk.

Do both support Dolby Vision?

Yes. The LG C5 has Dolby Vision and Dolby Atmos. The TCL QM6K has Dolby Vision IQ, HDR10+ and DTS Virtual:X as well.
