T400 Series - Docking Station Monitor Issues

Hi everyone,

 

I'm having issues with some T440/450's lately here at my job.

 

When docked with the ThinkPad Pro Dock (PN: 40A10090US), Dual monitors are not working correctly. We are using a DP and a VGA and the 2nd monitor is coming up as a non-PNP- monitor. The 1st one we can get to update with a driver, shows the model number, but when trying to update the driver on the 2nd, says Windows 7 (64bit) already have the best known driver for it and won't let us update it.

 

Computer Management shows Generic PNP monitor.

Ran all windows updates

Ran all Lenovo updates including BIOS updates.

 

This is becoming more and more frequent on users at my worksite.

 

I've been searching this site to get some answers, but nothing really solid.

 

What information can someone provide or info I can provide to address this?

Thanks

Re: T400 Series - Docking Station Monitor Issues

I did all the Windows update on the T450

Current monitors are Dell P2210 - but we've had issues with our Acer's as well..

 

Lenovo updates all completed.

 

I got the resolution to match a bit - however - the top and bottom of the monitor has a black boarder about 2"inches from top and bottom.


Reset the monitors display settings.

 

Please advise. PLEASE! Smiley Happy
