The lagom site isn't bad, but it doesn't really address the issue of excessive brightness. The recommended brightness for an lcd monitor, as I understand it, is about 120 cd/m2, yet on my Gateway XHD3000, whites don't really look white to me if I set the brightness below about 85% (at least at native resolution, where only brightness is adjustable on the OSD; more controls are available at non-native resolutions on this monitor), and at 85% on this monitor, the brightness may be around 339 cd/m2, so I'm worried that it's bad for my eyes. I went ahead and ordered a LaCie Blue Eye Pro for myself so I can check the ambient light and let it adjust my video card settings if necessary for proper brightness, though being able to calibrate my family's other monitors as well mitigates the cost. If apie172 lives alone and only has one monitor, it may not seem worth it.
