To calculate the min and max viewing distance for 4K HDTVs:
The suggested optimal viewing distance is between 1 and 1.5 (x) times the screen’s diagonal measurement (SDM).
1 x SDM = Min viewing distance for 4K HD TVs
1.5 x SDM = Max viewing distance for 4K HD TVs
To calculate the min and max viewing distance for HD TVs:
The suggested optimal viewing distance is between 1.5 and 2.5 (x) times the screen’s diagonal measurement (SDM).
A mathematical formula would look like this:
1.5 x SDM = Min viewing distance for HD TVs
2.5 x SDM = Max viewing distance for HD TVs
If the picture quality is not optimal, the viewer can see the columns of pixels.
Then, the television is too close to the viewer.
