Preventing XP from trying to detect monitor
mazinger-z:
Hello, this issue is bothering me very much.
How do I stop that DAMN XP from trying to detect what kind of monitor is hooked up and changing resolution / refresh rate? When this happens, I get a balloon popup telling me the resolution / refresh rate are too low and I should change them. I need it to keep the resolution that I chose.
Please help me disable this infuriating feature. :angry: :timebomb:
I found this:

But the interface I'm building has a cable directly soldered onto it and this cable doesn't have those wires.
I'm using the modified Windows ATI drivers and my XP has service pack 3 installed.

Have you disables your plug and play controls???

Also I would do a custom configuration which will allow you to set monitor res.. You may have to write a config or an autoexebat.exe file with the res you want in it..

disable buble info?

I was actually mixing 2 different things. One is the balloon dialog, that can be easily disabled in the registry. The other one is XP's monitor detection feature, which disables higher refresh rates when booting with no monitor attached. I think this won't be a problem anymore once I finally attach my PC to the arcade monitor (a normal 15KHz type), but it's quite annoying now that I'm using different monitors and TV sets for testing.
The interesting thing is that QuickRes (or maybe, the modified driver itself, as this also happens in the standard XP resolution selection window) gets fooled by Windows into thinking that refresh rates higher than 60Hz are available: if I start the PC without a proper VGA DDC monitor, I can select those modes but I only ever get 60Hz instead. Maybe the author can make the driver aware of this and gray out those modes.
This behavior also shows up if the monitor is turned off at boot time.
At least this is my understanding of the "problem". I'll update this thread if I find out more.
