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 16 in above the furniture top, so a 24 in high stand puts it at a typical seated eye height of 40 in.
On the wall. The TV uses VESA 300x300 mm and weighs 26.8 lb without its stand. Allow about 50.4 × 29.7 in of clear wall (1 in each side). It will stand off the wall by its own 2.2 in plus the mount’s depth, which the mount’s own spec sheet gives. See how to choose a wall mount.
