: Which HSV-noise values do not cause artifacts on an LCD screen? I have come to notice that certain HSV noise filter values applied to a uniform background colour look horrible when viewed on

I have come to notice that certain HSV noise filter values applied to a uniform background colour look horrible when viewed on an LCD screen under certain viewing angles. This is more noticeable on (cheap?) laptop/notebook screens.

Here are two contrasting specimen, made with the GIMP HSV noise filter for the RGB colour #F3F3E9 .

Below background becomes coarsely grained and patchy on LCD screens under certain viewing angles. It was created by applying the HSV noise filter with the following parameters:

- Holdness = 2
- Hue = 0
- Saturation = 0
- Value = 14




Below background is less offending. However, on an analogue CRT screen the grain becomes barely visible. GIMP HSV noise filter parameters are:

- Holdness = 4
- Hue = 3
- Saturation = 13
- Value = 13
