So this is pretty weird and obviously I'm missing something basic in understand how resolution is produced. What I really want to do is video capture a video game higher than my monitor's native 1440x900. I thought I can "fake" a monitor's resolution so I created a VNC between the Windows 7 PC and laptop. I then disconnected the VGA cable on the GPU, VNCed in with the laptop, increased the resolution to 2560x1600 and then tried to capture the application. On doing so, I got an error saying that directdraw couldn't be enabled (the same error through a VM as it turns out) even though I could expand the application did expand to the max resolution.
I then tried another way by disconnecting the VNC completely so that directdraw would no longer be an issue and I fired the application off via the command line. I got a different error this time as: "Problem setting '0x224x163789bpp (0hz)'
display mode" which I guess means something along the lines of.. couldn't start.
It seems like the GPU really does require a physical connection (at least in Win 7)? How does this work? Is it possible to create a dummy VGA plug which spoofs the gpu into thinking that the resolution is rendering successfully? If so then I guess this method would work. Any help appreciated.
I also tried the "desktop size and position" settings in the nvidia control panel. I thought you could create a higher resolution than your monitor supports, but allow the desktop to be scrolled. However there's no option in the control panel settings to increase the resolution beyond the native. I have no idea what that dialogue is meant to do. I tried everything in there and nothing allows for a higher than native resolution.. :/Edited by delatroy - 11/5/13 at 7:19am
