Presentation manager won't display on projector

[jonathanmedwards]

I had a presentation ruined because my T61P Vista wouldn't display on the projector. Presentation manager kept reporting the error:

Application popup: Error : The following settings you have selected cannot be applied properly. Change the setting and try again.
Display Configuration

Rebooting didn't help. But I went back the next day and it worked fine. Obviously a software problem, presumably Vista or ATI drivers. I can't tolerate this kind of unreliability. If there isn't a solution I will have to dump Vista, or Windows altogether.

Argh! I'm having the same problem. I've reinstalled presentation director and the ATI drivers to no avail. I've also just installed Vista SP1 and nothing changed.

Anyone have a solution to this?

thanks

After extensive googling, I found the following recommendation, which I have not tried myself yet.

I did have everything plugged in before powering up the first time w/the new monitor. In my case, I stumbled upon a setting in the Catalyst Control Center that fixed my problem.

In the Advanced View, under "Monitor Properies 0/Attributes", there was an option checked in the "Monitor Attributes" section labelled "Use Ectended Display Identification Data (EDID) or driver defaults". When this was checked, the drop-down lists for "Maximum Resolution" and "Maximum refresh rate" were greyed out, but I could see that the values were 1440x900 and 60 Hz, so I unchecked the option, and was then able to set those values manually. I set them to 1680x1050 and 75Hz, and then changed my desktop settings again in the Control Panel to match (actually, the monitor can only do 60 Hz at that resolution, so I set it to 1680x1050-60). Regardless, that did the trick, and my display looks much better now!
