KVM

I purchased a new ultra wide monitor, so I had to go an purchase a new gaming computer to drive it, then of course I needed to add Flight Simulator, then toy's like Logitech Flight Panels, Yoke, Throttle Quadrant.  I can't make my house payment, but I have a cool Flight Simulator.  In this process I found I still need my programming computer, so I got the new version of Multiplicity and use the KVM mode.  This works great.  One question I have is that the two screens are offset about 5 to 9 pixels, which is easy to see at the top, or bottom of the screen with a back ground picture.  Also the two pictures seem to have different light, one is darker than the other.  Is there a way to align these two screens, and any way to change the color settings so they match.  Obviously this does not affect my programming capabilities, just curious and seeking perfection.
