This reminds me of an old ViewSonic LCD monitor I have. It occasionally corrupts its EDID memory for some reason, which causes the computer to not recognize the monitor anymore. The procedure to restore it sounds similarly weird. You plug and unplug video connectors, the monitor power and boot/shutdown the computer in a certain sequence. I didn't believe that worked when I first read about it. I've done it several times over the years however and it did in fact restore the EDID every single time. https://www.tablix.org/~avian/blog/archives/2010/06/the_curious_case_of_viewsonic_s_edid/ https://www.tablix.org/~avian/blog/archives/2010/06/the_curi...
