Simple monitor serial number retriever

archrival · May 4, 2005

Fairly simple, requires newest beta version. This will ask you to enter a machine name (it defaults to your own) and then it will retrieve the Model Name and serial number of the monitor. Comments welcome.

great idea to create this script. but it doesn't work for me though.

the above screenshot was from a Compaq monitor and it didn't work. but i tried on a Phillips 107S5 monitor and it worked fine!

gd job!

Yeah, not every monitor will return the serial number. My monitor at home has the serial number 000001, I imagine all KDS VS-190 monitors return that same serial number. I wrote this script because we have Dell flat panels and I need to make sure they stay with the particular PC. When I rolled out the PCs, I forgot to mark down the monitor serial number. I'm an efficient type of lazy, yes I figured out how to retrieve it from my desk, but I don't feel like going around to all the PCs and writing down the serial numbers. So this works for me, most of the code I post on here is stuff I need for my job and I just like to share.

That's exact what I'm looking for, but it doesn't work on my pc!!!

No model and serial is shown!

It's stored, because Everest and AIDA shows the information...

Do you have any idea why?

I'm using the latest beta 3.1.1.87

thanks

I'm not too sure, this code has to decode what is already stored in Windows. I'm also not sure if those programs use WMI, I doubt it. Just make sure WMI is running and you have read access to "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Enum\DISPLAY". You could check the registry entries under Display for Device Parameters, that is decoded to determine the Serial and Name. If it exists, then I'm not sure, I'm willing to bet it does not. Those programs could possibly read the DDC/EDID information directly, that may be possible now via DLL calls, but that's not something I'd be able to figure out anytime soon.

I changed around the code a little, it's basically the same, I just don't ask to enter a new PC name if the entered one fails.
