Help much appreciated with the problem:
l Lenovo Thinkpad T60, Type 2007-ED9 (WinXP, SP3; 1G RAM; ATI Mobility Radeon X1300)
l External monitor (Samsung Syncmaster 2494) - using D-sub cables that came with the monitor and plug into the side of the computer.
It worked well before, it automatically started up with the external monitor as the primary screen and the laptop's screen as the secondary - something I didn't like and tried to change, and the problem seemingly began there. I went to Display -> settings to make the thinkpad's lcd as the primary (I am pretty sure that's all I did), which it did, but the external monitor, though still connected, went blank. The computer still detects it, as the screen's model and native resolution shows up on the display settings. The screen itself is just blank, it doesn't show the message that it's looking for a signal, but it does occassional has alternating "Digital" and "Analog" boxes showing for a few seconds (as if it's trying to determine the source of input), and then it is blank, as it otherwise just does.
The monitor and its cable are working well, because extending the desktop onto it with another laptop worked fine.
WHAT HAD BEEN TRIED
I am at a loss as to what is the problem. I don't have a dock, and I only have the cables and ports that came with the basic monitor and laptop. If you could think of something, it'd be very much appreciated!
Thanks very much in advance.
