The most common regret after buying a TV is that it turned out too small. The second most common is a neck that hurts because the screen hangs too high. Both are easy to avoid with a tape measure.
Start with the distance
Measure from your eyes on the sofa to the wall where the TV will stand. For a 4K screen, divide that distance by 1.5: the result is the diagonal that fills your field of view without showing pixels.
- 1.8 m (6 ft) from the screen: 50 inches
- 2.1 m (7 ft): 55 inches
- 2.5 m (8 ft): 65 inches
- 2.9 m (9.5 ft) and more: 75 inches
OLED or QLED
If you watch mostly in the evening with the lights down, OLED gives true blacks and the best contrast: see the Lumera Vista OLED. In a bright room with big windows a QLED panel is the safer choice, because it is brighter: the Lumera Aura QLED reaches 1000 nits.
Height matters more than you think
The center of the screen should be at eye level when you sit, usually 100-110 cm from the floor. Above a fireplace is almost always too high.
Do not forget the sound
Thin TVs have thin sound. A soundbar with a separate center channel, like the Sonark Beam 3.1, makes dialogue clear without raising the volume.
