Hello.
I recently bought used Samsung SyncMaster 2494HS and the display has 3 input ports (VGA, DVI, HDMI). When I'm using both DVI and HDMI inputs none of them displays anything it's just not working and when I switch sources it's black screen on every port until I unplug one of them. However it works perfectly fine when I'm using VGA and either DVI or HDMI and switching sources does switch screes of each PC I have plugged to them. Can it be that because DVI and HDMI are both digital signals and although switching source has 3 levels not just digital and analog but DVI, HDMI and VGA that's how it supposed to work, or maybe a display error?
