Hello,

Our setup is a desktop PC (Win10) with 2 monitors and a projector. The secondary monitor serves to duplicate what is on the projector - i.e., if you drag a window onto the second monitor, it will show on the projector as well. This all runs through an IOGEAR 4-port splitter using VGA cables.

Ever since we upgraded our Win7 PC to a new Win10 PC, the left side of the second monitor has been cut off, while the projector shows the whole screen as it should. If there is a sentence across the screen, the projector will show the whole thing, but the first word or two will be cut off on the second monitor. All the resolutions seem to match. I've tried adjusting the display via the built-in monitor menu, but I am only able to move left or right, rather than shrink it. Thoughts?
