Well it turns out i was able to fix the problem, i did this by reseting some ini files.
But i have another question regarding external displays, if i were to connect a desktop pc to a tv, would it work in the same way as connecting a pc to a tft monitor, ie would the windows desktop appear on the tv with the wallpaper and everything, showing all programs or is it jus certain programs that show up, ie dvd programs. Thank you for your help
