Preventing XP from trying to detect monitor

<< < (2/3) > >>

mrazy1:
The firmware you are using should select the right driver but if you are using more then one monitor then it may not know which one is which if they are close. Maybe why you are getting window pop.. Plus not all countries use 60hz but 50hz but at this point I do not think I can help just know that you can set res in an autoexec.bat file to one you want if you have the right drivers installed.. by using a different configuration you can select which res you want if you are using different monitors for different reasons. without installing all the drivers at one time. Just an Idea

mazinger-z,

There is an undocumented option in ATI drivers for doing that:

- Find the registry key where your driver settings reside (you can get it from GroovyMAME logs)
- Create a new DWORD value named DALRULE_DONOTPERFORMDISPLAYDETECTION
- Set its value to 1 (0x00000001)
- Restart

Hope it helps.

mazinger-z:
Aaah, thanks a lot Calamity! I had a feeling that a "dalrule_something" would do the trick.  :notworthy:

Thanks to everyone else too.

caskad:
Hello,

can i apply this trick to prevent plug and play HDMI monitor detection?

my test result give me strange issue, (need to restore back because buggy screen)

thx

Calamity:
Hi caskad, this should prevent both outputs from being detected, but probably the VGA won't be used as primary anyway. However, you can try some experimentation.
