External Monitor - Need Help Please

by camiller000 / September 28, 2009 5:10 AM PDT

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.

What is "a newly configured"?
by R. Proffitt Forum moderator / September 28, 2009 5:34 AM PDT

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.

The lenovo X300 is 'newly configured' meaning I just put in a new HDD and reinstalled everything via the recovery discs. I have updated video drivers and monitor drivers.

The dell monitor is an 17" LCD. (not a widescreen). I believe the max resolution is 1280X1084. That is what it is set at and working with on another laptop I am able to use. It is about 4 years old, the make and model are not identifiable for some reason (this was a stock dell monitor they shipped with systems 4 years ago).

As I stated, the monitor works fine when used with another laptop (different model).

What else can I tell you? I thought these were pretty much plug and play? I guess not.

Change the video resolution ...
by Kees Bakker / September 28, 2009 6:28 AM PDT

of your video card (in Safe Mode) to one supported by the monitor.

There's no such thing as a "monitor driver". But some monitors have a "monitor.inf" file that tells Windows what they support. And Windows is smart enough then to only show those video modes in the desktop properties to let you choose those.

"Updated video and monitor drivers" leads to the "why" question.

Thanks for educating me on 'monitor drivers', If you go to monitor mfg site they allow you to DL drivers - I guess that it a misnomer.

You asked why I tried to update drivers - it was suggested that the drivers on the recovery CDs could be outdated, so that is why.

If I make the change you suggested, won't that also affect the onboard laptop monitor?

(NT) Easy to change it back if it does. Just try.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
