Stitching monitors???

[mattflahertyracing]

So to start off I have a quad monitor setup (1 up top and 3 monitors across the bottom) that I use mainly for work purposes and would like to also use it for gaming. I am trying to find a program that is capable of stitching the 3 monitors together to make one super ultra wide monitor for use in games like ATS, Nascar Heat, MFS and others that support ultrawide setups. I know that I can stitch the bottom 3 monitors together with Nvidia but when I do this it disables the top monitor (see photos below). I don't know if it makes a difference or not but I am using a laptop provided to me from my company that only has 1 HDMI out and 1 mini displayport. The way I have my setup right now is the top monitor is using the HDMI port and the bottom 3 are running off of a startech minidisplay to triple HDMI splitter. The laptop is a Dell Precision 7530 with a Quadro P1000. Also it would be nice if the program has a feature where I can stitch and un-stitch the monitors together with a hotkey/macro.
