Extended Monitor Problem
 

I was working thur nite while in the middle of a song the lcd monitor goes black..I checked the cables, the ac cord, ok..I spent quite a while on display settings...settings are right I think..during all this I left the songs playing in auto mode.. the extended monitor would come back on for maybe a minute then for no reason go black...this laptop is a Dell Inspiron 6400, about 2 years old, it has done three shows a week for the past 2 years its been a great laptop...specs are'nt great....1.66ghz...980mhz....504mb ram...
I had an old laptop in the van its one of the first sold by mtu, it still works except its wore out...I hooked it up and finished the nite..monitor and cables are fine....the dell is fine in every respect except for the.. extended monitor..
any ideas or help would be appricated...thanks Ken

which one went blank, your laptop screen or the monitor..are you sure you have the laptops power cord plugged all the way in? i did a private party a few years back using my old laptop, and its was doing fine when all of a sudden the screen went black, i kinda forgot to plugged in the power cord and it was running on battery...:g:g

extended monitor problem
 

I ran the old laptop with the monitor and cord configuration, cord and extended lcd work fine..the problem has got to be with the dell video card, or setup, or drivers, or?????????

Sounds like a video card problem to me. Contact Dell and see what you need to do to get it repaired.

go to dell support and they have a bunched of solutions to your problem you can choose from.

extended monitor
 

went to dell support downloaded drivers etc. no help.. talked to dell person he thinks its either video card or vga plug, in either case he says it would require a new motherboard, estimate to buy and install $450 or more ..... so I bought another laptop the same model..I thought my troubles was over but now I need to get the hoster software on to the new laptop, but apparently that can't be done without talking to mtu and they are not talking.....

Read your other post. That has been fixed.
