It's new, fails, so you call it in under warranty.
This discussion almost can't start. No make, model, what video settings. That is, no details.
I have a working dell LCD monitor that I am trying to use externally with a newly configured Lenovo X300.
Using the setup in both Lenovo and XP I can't get the monitor to display. I have installed updated device drivers from Dell and Lenovo. The only thing that happens is that a message is sporadically displayed indicating "Analog Input Cannot Display Video in Current Mode".
Any thoughts on how to resolve this. The monitor works fin on another laptop I have. I have tried another moniotr with the problem laptop and have the same issue.
