I recently upgraded my graphics card and added a second 14" monitor.
When I run Blender with just my main monitor active it runs fine.
When I run in “Dual View” mode with the second monitor as a seperate display Blender is pretty sluggish.
If I use the horizontal spanning option Blender runs fine again but both monitors have to be running at the same resolution for this mode, so I’m limited to 1024x768 (max res of the smaller monitor).
I’ve been through the nview properties looking for things to tweak but nothing has helped so far. Is anyone else using Blender in dual view mode with displays at differing resolutions?
My graphics card is a 128mb Asus V9520 (Nvidia Geforce FX 5200). My main monitor normally runs at 1280x1024.
