Hi, Was wondering if .....
Prob: There is an interesting bug with some HTPC connected to an AVReceiver using HDMI where the graphics card resets to its default (eg 800 x 600 instead of 1080p) when the AVR is switched to another input and back again. The problem is the HTPC's graphics card detects that the Monitor is "lost".
Background: I got great support from this fourm making a script that would auto change refresh rates for Blu-ray / HD-DVD Playback when PowerDVD started (
http://www.autohotkey.com/forum/viewtop ... highlight= & see code block below) .
Soln: Instead of "#IfWinExist CyberLink PowerDVD" to kick of a action Is it possible to detect either when the monitor is reconnected, a particular resolution, or some other way to auto-reset the graphics properties back to a particular setting using AutoHotKey?
Thanks
Nathan
