Any ideas why my new tosh 27wl56 keep changing picture aspect when playing xbox? for some reason it switches from 'wide' to 14.9 after about 2 mins for no apparent reason??? I can manually change it back but by this time i've crashed and the race is lost!! Also if you have one, what screen settings are you using? there seems too many adjustments and the manual is no help at all really. plus i think the 'preset' ones are awful. Thanks in advance.
