A new member @ravipra noted that a change to his GRUB configuration in linux helped his eyestrain and he believes is related to a dithering setting. Since "seeing" dithering on a Dasung is the only visually objective proof we have so far I would like to see if this setting change alters what you see on your panels...meaning is there dithering visible before the change and not after. The setting changes are below, as is his original link, and while I am not great at linux I can advise you how to make the changes if you aren't a linux user but are still willing to try with a live USB etc. Thanks.

In your etc/default/grub file make the following change (or whatever resolution is appropriate for your panel's native resolution)...the command "xrandr" can tell you if you don't know and @ravipro's posts explain in more detail.

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" would become
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash video=eDP1:1920x1080-16"

The theory as I understand it is that last value "-16" is stopping the panel from dithering since its not requesting more than a 6 bit panel (for laptops in his and my case) can do in 3 channels ( RGB ) so 3*6 = 18. If you have a true 8-bit panel you'd need to use 24 or less I believe..I am not sure if just using a minimal setting for everything would work or if it somehow needs to be matched up to the result. I may be getting the details wrong and hope he will return and create a more thorough thread just about this but would like to get some testing done ASAP to see if this is a path worth spending more time on.

I am interested in what variations of this final bit setting ("16" etc) does to the Dasung's viewable dithering and if the additional changes he later lists make a difference. @ravipra said using 16 on his lenovo laptop (6 bit native panel) was helpful but 24 was not leading him to believe it needed to be equal to or lower than the 3 channel * panel depth in bits total. He said he will compile a more thorough list of all his settings but even testing what he listed so far should show a change on the Dasung if that GRUB value is actually changing anything in reality since we know the Dasung's show visible dithering when it is present.
