Tips & Recommendations
Optimal Viewing Distance
For your 55" TV, sit approximately 7.3 feet away for the best viewing experience. This distance provides immersion without eye strain.
Room Lighting
Avoid placing your 55" TV opposite windows to reduce glare. Use bias lighting (LED strips behind the TV) to reduce eye strain during dark scenes.
Picture Calibration
Out-of-box settings are often too bright. Switch to "Cinema" or "Movie" mode for accurate colors. Disable motion smoothing (soap opera effect) for film content.
Wall Mounting
A 55" TV should be mounted with the center at eye level when seated (typically 42-48" from floor). Use a tilting mount for flexibility.
Gaming Setup
Enable Game Mode to reduce input lag. For 55" screens, ensure your console outputs at 4K for the sharpest image at typical viewing distances.
