Pro Tips

For 4K TVs, you can sit much closer without seeing individual pixels, allowing for larger screens in small rooms.
If the FOV is too high (>50°), you may experience eye strain as you have to move your eyes to scan the edges of the screen.
THX recommends a 40° viewing angle for 'immersive' cinematic experiences.
Viewing height is also critical; the center of the screen should ideally be at eye level.

Fun Facts

Formula: Optimal Distance = Screen Height × 1.5-2.5 (THX); Distance / 0.84 = Max TV Size
