Help! stuck with odd resolution

Running 4.2.1 and using greenpoison JB. I used a program to TVout and somehow got stuck with resolution that is causing spaced icons on homescreen and keyboard problems. I think it is giving me the Iphone double tap spacing between things and causing havoc (lines in bar at top of screen are all colors). I tried to use Itunes restore to correct the problem to no avail. What can I do now? Please let me know. Im anxiously biting my nails... noob JB here.

 

No I did not have that installed only BTkeyboard and BTmouse plus activator and TVout2 (which I think was the problem). I actually fixed the problem by installing sbsettings and respringing the whole thing. Works fine now. A bit of a scare though as i thought an Itunes restore would fix it and it did not. All is well now.
