Short answer
The 85QM8K measures 74 × 42.2 × 2.1 in without its stand (43.8 in high on it), weighs 85.8 lb and mounts with VESA 600x500 mm. It’s a 2025 Mini LED TV with a 144 Hz panel; sit 8 ft 6 in to 11 ft 6 in away.
The TCL QM8K QD-Mini LED in the 85-inch class (85QM8K) is a 2025 Mini LED TV. Every number below is from TCL’s US spec sheet, re-typed into our own table; the few we work out from it are marked.
Note from the spec sheet: Four HDMI inputs, two of them HDMI 2.1 (4K 144 Hz); the HDMI 2.1 count is from independent reviews. The 75-inch column of the sheet lists a 61.7-inch width, which is impossible for a 74.5-inch screen, so the 75QM8K is left out until we can confirm its numbers.

Will it fit?
On furniture. The sheet doesn’t give the stand’s width, so measure the feet before choosing furniture narrower than the TV. On its own stand the screen’s center sits 22.7 in above the furniture top, so a 17 in high stand puts it at a typical seated eye height of 40 in.
On the wall. The TV uses VESA 600x500 mm and weighs 85.8 lb without its stand. Allow about 76 × 44.2 in of clear wall (1 in each side). It will stand off the wall by its own 2.1 in plus the mount’s depth, which the mount’s own spec sheet gives. See how to choose a wall mount.
