I have a graphics card with on two ports, an HDMI and DVI.

For a third monitor I was going to use a DVI splitter (like this one http://aluratek.com/2-port-dvi-video-splitter) to extend the desktop. Will this work with two monitors with different resolutions? If anyone has tried this let me know. Thanks
 
Right it would be an extended monitor running at 3840 x 1080.

Since one of my monitors runs at 1920 x 1200 and the other at 1920 x 1080. I would be stuck with a black line at the top and of the 1920 X 1200 monitor correct?
