Questions and answers

Which is better for a bright living room?
The TCL QM6K. Its High Brightness Pro backlight holds up better in daylight, while the C4 has no anti-glare coating and lower full-screen brightness.
Which is better for gaming?
The LG C4 for PC gaming, because it is G-Sync certified with FreeSync and four HDMI 2.1 ports. The TCL runs 144 Hz native with Game Accelerator 288, so it is close for console play.
Is the LG C4 worth about $550 more?
Yes if you watch in a dark room and want perfect blacks and wide viewing angles. If the room is bright or the budget is tight, the TCL QM6K is the better buy.
Which has better sound?
The TCL QM6K. It has an ONKYO 2.1 channel system with a built-in subwoofer and Dolby Atmos. The C4's speakers are weak at high volume.
Does the LG C4 risk burn-in?
Yes. OLED pixels can retain static images such as news tickers or game HUDs. One owner reported burn-in. The TCL's LED backlight does not have this risk.
Can I get a bigger screen on the TCL?
Yes. The QM6K comes in 50, 55, 65, 75 and 85 inches. The C4 listing here is the 55-inch model.
