Hit Enable edid emulation by accident, need help

(1/3) > >>

Milsancho:
Hi guys,
I had a Windows 7 system working fine with the latest drivers for an R7 240 card. I wanted to run Video mode maker to make some changes and accidentally hit Enable edid emulation button in the Video card tab and now the 15khz display shows a black screen (with some illegible words on the lower right corner, I think). Rebooted the system, nothing was reverted, I'm afraid.

I also have a VGA CRT monitor plugged with a DAC. Custom modes (and edid emulation) were installed for the 15khz TV only, the VGA monitor just used the standard ones. I'm quite sure the output selected in the menu before hitting the Enable... button was not the one for 15khz.

Any help on how to solve this situation would be really appreciated, as reinstalling Windows 7 would be a real PITA after all the changes and updates I manually made.



I'll add it's definitely out of sync, so, as a first move, I'm not sure if it's better to try Windows' safe mode or swap cables to get signal on the VGA monitor or anything else. I prefer to ask for advice here before any attempt even for that anyway. Thks!

Calamity:
Swap cables, disable edid emulation, swap again.

I connected the VGA output to the VGA monitor and this tells me that the signal is of 16khz, so black screen. Tried again with the 15khz monitor in case but it's still the same. Windows desktop is there, and I'm not sure it is out of sync or just a resolutiion you can't work with. The mouse cursor is visible and you can right click but menus arent displayed.

With disabling edid emulation you mean via Video mode maker and hitting the same button again?

You could try connect PC via hdmi if available. TV through hdmi should accept 15 khz modes. Also many monitors will accept 15 khz if monitor has HDMI.

Well, my monitors don't support HDMI, but as I mentioned, I used a DAC (HDMI to VGA) for the PC monitor. But it's no use because the output Windows has enabled is the VGA one, which somehow seems to be out of sync for both, the PC monitor (which detects it as a "16khz signal") and for the TV (which shows the desktop in a completely unusable and broken way).

I guess my only option now is booting Windows in safe mode? Does this mode disregard the custom video mode or the latest output in use and which output should I pick for that? Will I'll be able to disable edid emulation from there? Always better to ask before breaking anything else......
