U2412M, no longer recognized by Windows 10?
Hi,
I have a Dell XPS and two Dell monitors, a U2412M and a U2415. Yesterday I had to do a Windows 10 reset because of a software problem. However, now Windows 10 only recognizes the U2415. The U2412M it sees as a generic PnP monitor and sets a horrible resolution of 640x480, which is unusable. Previously both monitors worked fine on Windows 10. I spent much of yesterday with Microsoft support staff, with no success. I cannot find a Windows 10 driver for this monitor. I know I probably should have checked for a driver first, but I can't say I ever had a problem with a monitor when changing OS.
Any suggestions?

I have had exactly the same problem. I have been using Win 10 and U2412M for 9 months without a problem and then suddenly a couple of days ago resolution was reset and it was using generic PnP Monitor driver. More details can be found on a post I made in Windows Secrets Lounge at link below:
windowssecrets.com/.../177431-Driver-Problem-with-Dell-U2412M-Monitor
I eventually fixed it by swapping connection from monitor to CPU from VGA to DVI using the lower DVI connector on CPU. I rebooted and straight away it went back to correct resolution.

Many thanks for the quick reply. I downloaded that, unzipped it, and then ran the Dell Monitor Driver Installer. It gave me the following:
The following connected monitors have been detected:
Dell Plug and Play Monitor - DELA0BA
NVD Plug and Play Monitor - NVD0000
Drivers for the following monitors have been found:
Dell U2412M(Analog) - DELA079
Dell U2412M(Digital) - DELA07A
Dell U2412M(DisplayPort) - DELA07B
Drivers for the following connected monitor can be installed:
None
Please connect your monitor before running this program.
For some reason my U2412 is not being recognised. It is plugged in, it is showing an (awful) image. I have tried to force windows to update the driver and manually located the folder with the new driver, but it just says, "Windows has determined that the driver is up to date - Generic PnP monitor."
Any ideas?
Kind regards

So this is an operating system fault and not a monitor hardware fault. Ask the guys on the Windows 10 board about what Windows 10 chipset or other drivers have not been installed correctly since the Windows 10 reset.

This is not a Windows 10 issue. I have the same issue with one of two Dell U2412M monitors. Suddenly, one of them wasn't recognized any;ore. Mine shozs a generic monitor with a native resolution of 1024x768.
The issue is persistent across all my installed OS'es.
I'm wondering if the DVI port may be broken. I wil try to connect using DP... see if that fixes things.

Its a while ago, I think that I had a display port and a hdmi port on my video card, I played around by connecting different screens using different cables, and suddenly it worked. There was no setting that was changed and no software update etc, I abandoned trying to daisy chain the displays. I was just turning off and plugging in, turning on, then turning off, changing cables, turning on, ... then suddenly success. I am almost afraid to touch them now in case it goes again.

MrkR, for my notes, what is the 20 digit serial number and revision A0x of the U2412M?
