I have used sketchup for sometime though skills are limited compared to what the rock stars do. I got a new dell inspiron laptop and when trying to use a monitor i get only a white screen. If I move the window back to the laptop all is well. The laptop is connected to a “plugable” unit that acts as a docking station providing monitor, network, sound etc. The monitor is a vga pluged into the docking station gadget. It was worked well in the past and I’m able to use all other programs on the monitor including autocad. I cannot plug the monitor directly to the laptop directly as the unit does not have a VGA plug in. I searched through the forums and didn’t come up with this sort of thing. Seems odd only sketchup would have an issue with the monitor if it’s a grafics card issue.
