Hdmi

Try finding it on your laptop. Right click your desktop, click on screen resolution. Then, select your TV from the display drop down menu and then adjust the resolution to the one native to the TV.
 
i went into graphics options and panel fit and then selected scale full screen, but nothing has changed. also the sound is not coming from my tv. it is coming form my speakers
 
i worked for almost 2 1/2 weeks trying to solve my issue with Ghost Recon Future Soldier no playing in full screen and it turns out i needed to adjust my TV to a different zoom to play it full screen... what a NIGHTmare THAT was to figure out.

USUALLY if there is no solution, or NOONE is having a similar problem (as w/ me and GR-FS) it is a setting or something specifically related to you, your computer settings, or TV settings.

hope this helps
