Common TV mounting mistakes include positioning the screen too high, causing neck strain, and not accounting for glare from windows or lighting. To fix height issues, remount the TV so the center aligns between forty two and forty eight inches from the floor, matching seated eye level. For glare, reposition the TV away from direct sunlight or use a mounting bracket with tilt and swivel capabilities to angle the screen. Adding blackout curtains or blinds controls natural light effectively. Always test the setup by sitting in different viewing spots before drilling holes. These adjustments improve comfort, reduce eye strain, and enhance picture clarity during all lighting conditions.
