These two land near the same price with very different priorities: a 65-inch OLED with perfect contrast or an 85-inch Mini-LED that is much brighter and 20 inches bigger. The one question that decides it: at your seating distance, is 65 inches big enough?

Pick the LG C6 65-inch if
- You sit within about 8 feet and a 65-inch set fills your view.
- The room is dark and movies with letterbox bars are your main content.
- You want the best motion and pixel response for gaming.
Pick the TCL QM8L 85-inch if
- You sit 10 feet or more from the screen and want a projector-like scale.
- The room has daylight or the lights stay on for sports.
- You want the brightest HDR highlights you can get without a projector.
Verdict
Buy the TCL QM8L if you sit far enough back that 65 inches looks small; size is the thing you notice every day and its dimming is close enough to OLED for most rooms. Buy the LG C6 for a dark, closer-seated room where black level is the point. The exception is a mixed-use family room, where the QM8L's brightness carries it even at closer distances.
Common questions
- Is 85 inches too big for a 10-foot seating distance?
- No. At 10 feet, 85 inches sits inside the range most guidelines recommend for 4K content. Use the size calculator to check your room.
- Does the QM8L bloom around subtitles?
- With up to 4,000 zones, reviewers describe blooming as near invisible in normal viewing. It is still not per-pixel like OLED.
- Is the 77-inch C6 a middle ground?
- Yes, but it costs considerably more than the 65-inch and the 85-inch QM8L, so it changes the budget question.
