long time no post (here) so please pardon my ignorance
I got me a uGreen KVM switch linked below so I can easily switch between two computers with a single monitor/keyboard/mouse setup.

big PC
Windows 7 Ultimate 64-bit
GeForce 8800 GT (PCI-e) DVI Out
mini PC
Windows 7 Ultimate 64-bit
Intel HD4000 (onboard video) VGA Out
monitor is a Samsung 920NW 1440X900 (16:10), 60Hz
all systems have their drivers updated (including the monitor)
the problem i'm encountering is rather simple but i can't seem to wrap my head around it. both computers share the same monitor/keyboard/mouse using the uGreen KVM switch. as should be the case, both systems are set to the proper settings for the monitor (manually selected in windows: 1440X900, 60Hz). on the big PC, it works fine but when i use the mini pc, i get an error message on the monitor saying "not optimum mode" and it's sort of telling me to set the system to 1440X900, 60Hz. if i plug the monitor directly and not go through the switch, everything works fine on the mini pc. i even tried using the hdmi output and used a hdmi to vga converter but it still gives the same error even if the hdmi output is set to 1440X900, 60Hz. i bought the switch specifically to easily switch between two pc's and it's a pain to unplug the monitor cables over and over just to make it work. when i set the mini pc to run at 800X600 (safe mode) or 1024X768, it works fine but running a 4:3 setting on a 16:10 monitor makes things look wonky and funky. i've tried switching the vga ports and even usb cables but to no avail. has anyone encountered a similar problem or has any experience with these? hoping for suggestions and help. thanks very much!
