For a dim environment, try around 80 cd/m2.2015-11-20 at 17:18 #1633
There’s usually indor lightning on unless I’m watching a movie. I’ll try 100 cd/m2.2015-11-20 at 20:32 #1632
You were right, 80 cd/m2 is the way to go!2015-11-24 at 13:29 #1631
It’s mid-day overcast and I’m finding I’m prefering 100 cd/m2. It feels like I’m going toward setting 90 cd/m2. I assume this is not the correct theoretical mid-way point of 80 and 100 but close enough maybe?

Keep in mind that some LED backlit monitor uses PWM method to dim the blacklight and do have high frequency flickering when the brightness not set to 100% , whch may cause flicker illness such as headache on some people.

I realized 100 cd/m2 is around the middle of all display standards(from DCI-P3 to AdobeRGB) so I tried sticking to it and ended up I prefer it for viewing photos and movies. But When I try to edit I find the results are too dark when I go back and compare with other media on my display. I’m now considering:
1. Swithing between 90 cd/m2 for editing and 100 cd/m2 for viewing
2. Setting 90 cd/m2.
3. Setting 100 cd/m2 and trying to improve my editing skills
What do you think?2015-12-27 at 19:59 #1628
It’s always good if you can control the lighting.2015-12-27 at 20:15 #1629
I have to work with what I have fow now. Do you suggest I set the brightness according to ambient lightning? If so, what does the formula look like? How do you deal with varying ambient brightness?2016-03-09 at 0:13 #2267
You could try installing a bias light behind the monitor in an otherwise dark room. It greatly improves the contrast of IPS displays and gives you a reference tone of gray to help with your editing. Its brightness should be no more than 10% the peak white of the display (eg. less than 12 cd/m² for a display with white at 120 cd/m²). For a usual 2.2 gamma you could set up a 35% gray field on screen and use that as your maximum reference ambient light. Then the absolute brightness of the display won’t matter as much as the eye adapts.
Personally, I have installed an RGB LED strip on all four edges at the backside of the monitor so I could have complete control over the brightness and white point of the light. The bundled controller can even store 6 presets of colour/brightness for varying calibration presets. It’s absolutely necessary to have a gray or light colored wall for this to work. Yellow paints can be fixed more easily. But overly saturated paints won’t work unless you cover the wall with a neutral curtain/wallpaper/etc.
