problem

in sony vaio laptop VGN-FW model , the resolution of display change automatically at startup , every time windows [vista] boot or login , resolution reset to high end (1600 x 900) even when it set to other supported resolution like (1360 x 768) in previous session. when i change the resolution to my setting and apply , every thing ok untill windows restarted or loged off , during next login , resolution turn back to default and ignore my setting



solution

disable "sony wallpaper setting tool" in task_scheduler
this task cause resolution reset at logon

control panel > administrative tools > task scheduler >  task scheduler library > sony > vaio wallpaper setting tool > click END (right corner side) > click disble
then set your desired resolution
