I would use a VNC app and do your mapping via wifi. Doesn't tell you whats wrong but it could help get around the issue.
I often do it this way using team viewer. Buts it somtimes is a little glitchy while mapping tiny structures.
Do you have any over or under scan settings?
I checked all the Nvidia driver settings and compared them to the notebook settings.
They're the same. Scale was set to "aspect ratio"
It must be a win or driver setting. After the show the PC was carried to a locked room and
got rewired and started by the club owner next day.
the projector resyncing to the input signal can cause this, I had this all the time with VGA connection.
if your projector supports it, try changing sync settings to manual.
Ok ill look @ this. I did the mapping (2560x800) routed to 2 epson 1775 through a 3Head Digital SE with HDMI cables.
The Desktop PC uses a 3Head Digital Edition and VGA cables. After finishing the mapping with the notebook i
disconnected the hdmi cables exported the sceen setup file and changed the projector source to vga.
I found that sending a full screen image to the projector and then forcing automatic resync resulted in reproducable results. The problem seemed to occur when the mapped output had a lot of black around the edges of the output,so the projector thought maybe it was not part of the image.
Ok every mask and slice in my mapping seems to be shifted like sb changed the projectors zoom.
It happens on both projectors all over the mapping. Ill do some tests in the club during the next week.
