Multi Monitor setup

so DisplayFusion / Extend Monitor does not work wid Splitter connected monitors ?
(presently using dual monitors with different displays wid two taskbars wish to add one more monitor but hve no extra port Hence all these queries. )
Thank u so much for insights.

presently i am using display fusion with standard monitor setup. not tried with usb graphic card.most probably it will work all function.i am using 12'' lappy with 22'' monitor.
for your second question splitter will not work as extended monitor.if your graphic card is double headed then will work.

I plan to buy this video card http://www.amazon.com/Gigabyte-GV-N75TOC-2GL-Graphics-Cards/dp/B00MW8NXAW. I have sold my 2 old benq monitor 1 left samsung and plan to buy only 1 monitor its http://www.amazon.com/Samsung-34-Inch-LED-Lit-Monitor-S34E790C/dp/B00Q7VCSGU and you can use it as a 3 monitors
