Philips 346B1C

the panel in this monitor is true 8-bit (not 6bit+frc)
in my case:
1) using an true 8-bit panel(Philips 243v DVI) in combination with Intel HD630 + dithering.exe does not give banding on the sample http://www.lagom.nl/lcd-test/gradient.php if temporal dithering disabled,
but it starts to flicker a little in general if temporal dithering enable
2) using not true 8-bit panel (6bit+frc HP 27es HDMI) in combination with ATI/AMD HD4850 + reg tweak "HDMI_DisableDither"=dword:00000001 give banding on the sample
"HDMI_DisableDither"=dword:00000000 not give banding on the sample(after restart), but it seems to add fatigue to the eyes
My next dumb guess is this: perhaps eye fatigue appears from a combination of TWO independent phenomena:
A) dithering of the monitor panel itself (in the case of 6bit+frc)
B) dithering the output signal of the video card
