when using air display with your ipad do you lose your original display resolution. im using splashtop remote and im curious if air display functions the same way. i have to use 1024x768 stretched on my laptop instead of 1280x800 when the ipad is connected. also there seems to be no way for me to shut the lid of my laptop and just use the ipad display in splashtop. can you do that in air display?
