If you have an AMD card, and have found Flawless Widescreen was not working, Hayden has supplied a work-around--
According to Hayden, AMD-CCC is not "returning the correct details about screens when you query them" (on my system at least). ie- it reports 2 monitors when you have 3. This means you will have to set the screen details manually, which will fix the issue.
To do so in Flawless Widescreen--
Settings/Configuration/Display Detection/ Override Display Detection (Manual). Then you enter the Total Width and Height for the array. Also where the hud should be (which will be the same as the resolution of the single monitor in the center.)
Bam! It works again for team red.
Confirmed on Shadow of Mordor, Metal Gear Rising.
--Sorry if this was mentioned before, but I didn't see it on a quick search. Now I have to go, it's 4th of July and Fireworks are starting.
