W520 external monitor only shows grayscale

2013-02-23, 8:06 AM

I bought a W520 in November 2011 and it has been rock solid up until last week. It has the nVidia Quadro 2000M graphics option and is running Win7 Pro x64. I use an HP ZR24w monitor connected via DisplayPort.

 

On or about the 13th of February 2013 I received some Windows updates and the external monitor stopped working entirely. Since this is my main work platform and I did not have time to troubleshoot, I continued using it with just the laptop display. A few days later another Windows update came along and updated the nVidia driver. The external display started working again, but it will only show grayscale. I've tried Googling the issue in as many ways as I can think of, but have turned up nothing.

 

Has anyone else experienced this problem? I saw a comment in another post ("W520 Video Driver Support", 2/18/2013) that "There is something wrong with the NVIDIA package being offered on Windows Update right now", but no specifics were offered. Is this just a case of waiting for another driver update, or can something be done?
 Thanks.

Since it seems to have coincided with various driver updates, I'd try grabbing the latest one off of NVIDIA's site instead of through Lenovo or Windows Update.

X61T: L7500, 4GB RAM, 500GB HDD, XGA screen, Ultrabase
W550s: 5600U, K620M at 1164/1281, 16GB RAM, 512GB SSD, 3K touchscreen

It's pretty clear to me the windows update package is bad and should not be installed.

Thanks ColonelOneill for the hint. That solved the problem.

 

Here are the details of what I did in case anybody else runs into the same issue:

 

I started by bringing up the Properties dialog for the nVidia card, went to the Drivers tab and tried to select "Roll back driver", but the button was grayed out for some reason. I then went to the nVidia site and had it automatically search for the latest driver for my system, but it brought up the same version that is presently installed. I then clicked on the "Beta and older drivers" link and downloaded the version immediately previous to this one, as it was dated a month before the "broken" one was released. After installation and a reboot the external monitor is now displaying color again.

 

I was a little nervous about installing a "generic" driver from nVidia vs. a specific one for this laptop from Lenovo, but it seems to be working fine.

I just saw this post after I had posted the exact same question. I will give this a try and hopefully it will resolve my problem as well.

Thanks.

Usually, Windows Update drivers are less risky because it would make sense for Microsoft to do testing before rolling them out over official channels.

There's usually no problem with using 'generic' NVIDIA drivers, although using Lenovo drivers means it goes through another level of testing
