[QUOTE="Spragleknas, post: 929383, member: 17435"] OK, seems like I finally managed to fix this on my setup :) From reading up on the issues, I assume the following - When TV and/or AVR is of - PC uses "dummy" monitor - When switched back on, Windows re-sizes to match correct resolution (given by AVR) - MP stays on "dummy resolution" - The registry-trick and VNC trick tries to do the same: set "dummy resolution" to 1920x1080 Several has reported getting something like 1600 wide picture. While fiddling with remote desktop (logmein w/o HDMI connected), I found that I couldn't set 1920x1080 resolution - only 1600x1200. Therefor I assume that the "dummy monitor" was limited to 1600x1200 (how stupid is that?), and unchecked the "Hide modes that this monitor cannot display" (see pic below) before setting 1920x1080 (although 30 Hz). [B]No problem so far :)[/B] I'm guessing that once this is disabled, the registry-trick might work as well (since you are no longer setting a resolution "banned" by Windows for this setting). My fear is that another "dummy driver" might appear - but if so, I know what to look for. [IMG]http://www.omnivex.com/media/KB/204/displayandmonitordialogmonitortabXP.png[/IMG] [/QUOTE]
