Specific monitor not recognized

Unlurky said:

Hello,

as of a few days I have an issue with one specific monitor of mine. I physically re-organized my office, but didn't change anything regarding software or hardware when it started. So I have no idea what the trigger of the issue was.

The monitor in question is a Dell U2713HM. I own three monitors and multiple PCs, so I was able to test a few things.
Unfortunately for connectivity reasons I need to get it to work with exactly this monitor.

- My PC recognizes any other monitor, and any other combination of monitors, except that one.
Also the exact ports of my PC are recognizing other monitors
- The monitor gets recognized by other PCs with no issues
- I tested different cables
- I tested different channels (DVI, HDMI, DP)
- I physically removed the GPU, booted, installed it again
- I updated drivers, uninstalled and reinstalled GPU
- I tried to install driver for that specific monitor model, but it doesnt work as the monitor doesnt get recognized.

Now I am a bit lost...
- The monitor cant be broken because its recognized by other PCs
- The cables are working with other monitors and other PCs
- The GPU is working fine with other monitors, just as all the ports of the GPU

If anyone has an idea what the issue could be I would be very thankful.

The PC that the monitor doesn't work on, regardless that it isn’t physically working, can you see it in the Display Settings where the monitors show, is it identified?

Look for that monitor in device manager (Enable show hidden) and delete it's entry then shut down, reconnect it and restart..

Maybe the "drivers"? Support for Dell U2713HM | Drivers & Downloads | Dell US

(They're not active drivers, but you want the .inf to be installed.)

The latest ones listed are for Windows 8.1 X64, but they'll probably work.

If the installer complains about the Windows version, I'd extract the archive using 7Zip and manually install the drivers.

I more often than not find that monitor drivers (old and new) show up in Windows Update>Advanced Options> Optional Updates




The reason I asked this, is because if it is identified in Display Settings, I was going to suggest messing with the settings for that monitor, like changing some of the settings for that specific monitor, resolution options maybe? (try 640 x 480 or something)
To see if it would give the monitor a kick.

Unfortunately nothing there.

Yes I also tried to change resolution but it didnt do anything.

• Open the Menu OSD
• Go down to Other Settings
• Go down to Factory Reset
• Check Enable

• Unplug the power and all monitor cables from the back and side of the monitor
• Hold in the monitor power button for 1 minute
• Plug everything back in
• Power on the monitor

I, by no means understand all this, but I think it relates to your problem somehow.

Extended Display Identification Data - Wikipedia

en.wikipedia.org

It's like your vid card is talking to your monitor, and your monitor is talking to your vid card.
But the one pairing where your issue lies... it seems like they aren't speaking the same language?

As I said...I don't understand all this stuff.
But your troubleshooting seems to have eliminated everything else.

I know you said it works on other PC’s

I have an Autodetect button on my monitor. I have had to use it before.
Not sure that yours does.
Monitors can behave differently depending on what they’re connected to

You could try the following, nothing to lose.

Do a monitor settings factory reset (whilst connected to the PC)

• Open the Menu OSD
• Go down to Other Settings
• Go down to Factory Reset
• Check Enable

Do a Monitor reset (Not connected to the PC)

• Unplug the power and all monitor cables from the back and side of the monitor
• Hold in the monitor power button for 1 minute
• Plug everything back in
• Power on the monitor

So that was a new glimmer of hope for a minute at least...

That’s interesting, I always thought the OSD displayed regardless.

Something on that PC hates that monitor with a passion. Trying to think of what else it may be.

Did you also try the Dell Display Manager Application on that drivers page?
(I don’t know what it does, I have a Dell monitor for one of my laptops but have never loaded that application)

In device manager, change your Display Adapter to the Microsoft Basic driver and reboot. Let’s eliminate your gpu driver having any sort of corruption.

Unlurky said:

Haha, it seems like it, yeah.
In these old Dell screens you can always access the channel select, but to go into the actual menu it needs to have a source.

I did, it doesn't do anything for my problem. But its a pretty nice tool you can use to divide your screen.


How do I do that? Select "uninstall device" of my GPU under display adaptors?
I did that, rebooted, reinstalled, didnt help. :-/
I have even formatted my PC in the meantime and the problem persists.

Did the basic driver allow the display to function?
