Playing games while having tv snapped

Re sizing it no but probably will in a later update you can make the snapped app to full screen.

Can you adjust the size of the snap screen?

When you say the cable is too short, may I ask exactly what you mean? If you arent going to use the kinect for video or motion control can you not have it near to the xbox simply to take your voice commands?

What Customgamer18 said. If you prefer to use voice commands, however, just say "Xbox, go to <app/game>". For example, if you're playing Call of Duty: Ghosts and decide to snap Netflix to the side, say "Xbox, go to Call of Duty: Ghosts" and it'll allow you
to control your game again rather than Netflix, your currently snapped app. If you want to go back, say "Xbox, go to Netflix".

Simpler method is to just say xbox switch to swap between snap windows , or if no kinect double tab xbox button on controller
