When I use my data projector, which is very infrequently, ie, once or twice a year, the display properties automatically change to suit the projector. That's fine. THen I reset the Display Properties to 1200 x whatevs...the correct setting. The laptop asks me to confirm changes, which I do. all is ok, but if the computer hasn't been used and shuts down, when I restart it goes back to data show settings. Honestly, It's so frustrating. If anyone can assist, that would be great. Thanks. M
