Subj : Graphics driver quest To : Ky Moffet From : Barry Martin Date : Thu Sep 11 2025 06:59:00 Hi Ky! > Found when rebooting XP VM the black background of the VirtualBox logo is > noisy but the rest is clear. > Same for when using Remmina: the remote machine will display noise with > its Terminal screen but everything else is clean. > So the fix is simple: run the new monitor at 60 Hz.

OK, sort of makes sense, and maybe a hare more if I add to the answer the possibility the 75 Hz portion of the driver understood the graphical areas but not the Terminal/Command Line sections because "old school". (Terminal window was noisy but graphical portion was clear - moved the noisy Terminal to the other monitor which maxed out at 60 Hz and the window was now fine; split between the two and half noisy and half good.)

When I scroll my messages I don't want smearing! Yes, using the 60 Hz refresh rate seems more than adequate. ¯ ® ¯ BarryMartin3@MyMetronet.NET ® ¯ ® ....
