Hi, I have been sitting 4 hours straight trying to work things out. I came home today and all my games were suddenly running in a minimized window. I tried to fix this through different resolutions and stuff but nothing helped. Then i plugged in my Hdmi cable and suddenly my games ran in full window mode. When i took it out again they went back to minimized, even if i changed resolution ingame. I know this fix with games is something computers have been doing for me, butt suddenly will not help me with anymore.

Worst of all is that when trying to fix the resolutions and stuff on my Intel R gma driver (which is my graphic card) my computer suddenly was unable to detect the hdmi cable on itself as it usually does. So i had to go into control panel - attach a projector or external screen and fix it from there. But as it seems no matter what i do here i cant get full screen size on my tv.

So as you see ive got two problems and i thinked they might be linked in some way. Can you help me out? I know i havent been to specific, but plz let me know if there is any details you need
