First I need to explain I have
Sapphire Radeon HD 4350 HDMI PCIe x16 with VGA, DVI, & HDMI support
Acer P191w monitor with VGA, and DVI support
The DVI connection has been working great for several months without issue till this morning. As a simple test to see why my monitor was showing a "No Signal" Message. I found my VGA cable and connected along side the DVI cable. I had a picture that was not displaying correctly. I also had this box moving across the screen with the message "Input not supported". During this time I had no control with the monitor buttons. The Monitor setup menu would not show.
Now for the next test what will happen when I disconnect the DVI cable? The monitor blanks out for a few seconds and the picture looks fine. The monitor setup menu now works again. Now I have narrowed it down to the DVI port on the card or the DVI support for the monitor that has gone out. I suppose it could also be the cable, but the chances of the cable going out over night are very slim but possible. Now there is really only one other option for testing this further. That would be to switch monitors with another computer that has DVI support.
I am inclined to think it is my monitor that has lost DVI support. If it wasn't for the monitor setup menu, I might would suspect the graphics card. However I am under the impression that the analog signal(VGA) is a second stage that is dependent on the digital signal(DVI) within the card. If this is true as long as I have a VGA signal the DVI signal should work. It could be the cable still yet, I simply don't have another one to try as of right now.
