|No DVI-D Signal on computer start up-|
I had a problem when out of the blue, my Viewsonic VG2230wm LCD monitor, started to show blank screen untill windows 7 loaded.
When windows loaded, it got stuck at 640*480 res.
However, when pluggin in with an analog display cable, all worked fine ( but still no native res
So, I booted up with this analog cable ( had no analog port on ATI HD 5800 series, so I used the DVI to Analog converting little dongle ).
When windows loaded, on analog display, I changed res. to some friendly 1024*768.
Then without turning anything off ( PC or Screen ), unplugged the analog cable.
Plugged in the DVI cables on monitor and Pc.
Waited a second..
Voila.. it automatically turned on as 1680*1050
Then turned off the system, just to check if all was ok permenantly... Did a shutdown. Restarted again, and all is still OK.
Can see BIOS, bootup and everything with the DVI cable .. again...
The occasion when all this happened was, our cleaning lady pulled the computer a bit too far and stretched the DVI cable too much.. bending and partially dismantleing them from jacks.
When I plugged them back, all was like hell.. Even thought my graphic cards port or monitor port got damaged.. but.. I guess not.
Hope this helps.
