one thing you failed to mention do you have integrated video or a actual graphics card if integrated you need to f8 again and change it back to the way it was then hook your big monitor back up and play with the buttons on the front of monitor they do have a bright and a dark and contrast on them my computer monitors has 4 buttond one is menu arrow keys to select what feature you want to do and then a select button try that if that dont work then you have a faulty monitor and you could go under monitor propertys and change the refresh rate you have 50 hz 60 hertz 80 hertz keep playing with the hertz if that dont work if its integrated video check with the company and see if they is a driver update for it hope this helps if not let me know we will try something else
Hi. i have a problem!! for starters its with windows XP. Ok i have this large monitor thats crapping up n is really dark, i was trying to play a game but was too dark so i decided to put back on my old monitor which is lighter but less res n smaller. so i put it on but cause it couldn't handle the larger res the other monitor it had it wouldn't show windows when it loaded. so i did f8 on start up, went into safe mode, changed it there n re-booted. it still didn't come up with windows so i f8 on start up again and enabled vga mode. now the computer just keeps restarting just before it opens windows, no matter which monitor i have on!!! how do i get round this????
