external-display

when it rains, it pours! Im helping a friend with his Dell Inspiron 1520. The hdd crashed and and top of that, the screen is cracked. I've replaced the hdd (SATA-5400), but the lcd replacement is only comin in a months time. I've tried to:

hook the laptop up to an Acer 18.5" lcd monitor via VGA,
boot up into Windows 7 installer,
get to the Step-1 screen,
Switch to external display (Function-F8)

...and get the "Input not supported" message on the Acer lcd. I know that this is a resolution problem, but cant for the life of me figure out how to solve this. I've also tried, hooking it up to my TV via Composite cables (got a VGA-Composite adaptor).

Please could someone advise me what to do? -Thank u!

I hope this question doesn't get closed at once :) I have an old laptop, a Compaq NC4200, which is going its final laps around the track these days. Battery is dead, and everything kinda runs slow. It also has only 1GB of memory, and even though I don't know if it can take more, I probably wouldn't… >>> More
