LG C4 OLED TV vs TCL QM7K 55" QD-Mini LED 4K TV

Buy the TCL QM7K if you want the most TV for the money: it is $430 cheaper at $599 at eBay versus $1,029 at Walmart for the LG C4 as of November 7, 2026, and its mini-LED backlight holds up better in bright rooms. Buy the LG C4 if you watch in a dark room or game seriously: per-pixel OLED contrast, four HDMI 2.1 ports with G-Sync and FreeSync, and 178° viewing angles are things the TCL cannot match. The C4 is the better picture for a dedicated theater; the QM7K is the better value for a living room.

Today the TCL QM7K 55" QD-Mini LED 4K TV costs $430.00 less at its best price.

Questions and answers

Which is better for a bright living room?
The TCL QM7K. Its anti-glare screen and mini-LED brightness handle daylight better, while the LG C4 has no anti-glare coating and can look washed out with windows behind you.
Which has better picture quality in a dark room?
The LG C4. OLED pixels turn off individually for perfect black and infinite contrast, which the TCL's backlight zones cannot fully match.
Is the LG C4 worth $430 more?
Only if you watch in a dark room or game on PC or console. At $1,029 at Walmart versus $599 at eBay as of November 7, 2026, the TCL covers most living-room needs for less.
Which is better for gaming?
The LG C4. It has four HDMI 2.1 ports, VRR up to 144 Hz, G-Sync and FreeSync, and a 0.1 ms response time. The TCL is limited to 120 Hz with no listed variable-refresh certification.
Which lasts longer?
The TCL has no burn-in risk, so it is the safer long-term pick for news tickers and static logos. The LG C4 is OLED and one owner reported burn-in.
Do both support Dolby Vision?
Yes. The LG C4 supports Dolby Vision, HDR10 and HLG. The TCL supports Dolby Vision IQ and HDR10+.
