LG C4 OLED TV vs TCL QM8K QD-Mini LED TV

The LG C4 is the better pick for dark-room movie watching and gaming, thanks to OLED's perfect blacks, wide viewing angles and four HDMI 2.1 ports.

As of November 6, 2026, the C4's best new price is $1,029.00 at Walmart and the QM8K's is $1,299.99 at Queen City Homestore, so the C4 is currently about $270 cheaper.

Questions and answers

Which is better for a bright living room?
The TCL QM8K. Its Mini LED backlight reaches much higher brightness and its anti-glare panel cuts reflections. The C4 has no anti-glare coating and lower peak brightness.
Which has better picture quality in a dark room?
The LG C4. OLED pixels switch off completely, so blacks are perfect and contrast is infinite. The QM8K's local dimming is strong but can still show slight blooming around bright objects.
Which is better for gaming?
Both are strong. The C4 has four HDMI 2.1 ports, G-Sync certification and a 0.1 ms response time. The QM8K runs 144Hz natively and adds Game Accelerator 288. Pick the C4 for console variety, the QM8K for the highest frame rates.
Is the TCL QM8K worth the extra money?
At $1,299.99 versus $1,029.00 for the C4, only if you need high brightness or an anti-glare screen. In a dim room the cheaper C4 gives better contrast.
Which lasts longer?
The QM8K has no burn-in risk, so it is the safer long-term choice for static content like news tickers or a PC desktop. OLED panels can develop burn-in over years of static images.
Can I use either as a PC monitor?
Yes. The C4 is popular as a monitor for its contrast and low input lag, but watch for static taskbars. The QM8K's anti-glare panel and 144Hz rate suit desk setups in brighter rooms.
