I have 2 versions of this EDID. One has a much longer block of code, the other, about 1/4 of that.
The long block EDID does not load in Nvidia. The shorter one does. I must have done something years ago to get to the shorter version, but I cannot recall what.
I use this EDID for a ROG Strix XG17AHPE monitor I have. It displays 3D when the EDID is loaded, but I have to tilt the monitor to a little less than 90 degrees to see it more clear, as horizontal, it is too dark.
I have been encountering many problems loading this EDID recently. I don't remember so many problems in the past. My native laptop screen is 120hz QHD 2560x1440 (TN) - AUO B173QTN01.4
The panel which I used to have, and pulled the EDID from is a 17.3" FHD 1920x1080
Sometimes, I encounter a black screen when the EDID is loaded. I reboot, and sometimes it is fixed. Sometimes not. I've spent 6 hour days trying to get it to work, and cannot seem to find out why it sometimes does, and sometimes does not. Re-installing Nvidia Quadro drivers, etc.
Can you post the files here? The black screen on boot is a bug in NVIDIA's driver when using multiple displays (your laptop display + the monitor). See this post for a workaround: https://www.monitortests.com/forum/Threa...wn-scripts
Thanks for the help and linking to the workaround! I'm also going to try out the EDID from the monitor you provided.
The ASUS VG248QG should work if you turn on ELMB and turn off FreeSync in monitor settings. It's been confirmed by some people I know that work with this monitor.
Here's the EDID from a laptop I've been using, in txt format.
***UPDATE***
Sweet mother, it worked!
That 'black screen' workaround is a work of art. It has solved all of my problems. I wish I had known of that before. I re-installed my video drivers so many times after booting into safe mode to delete them first. Formatted my computer once. To make things worse, I have to boot into not enforcing digital signatures to install my video card because their drivers need a workaround on my machine. Mercy.
What a fix!
The ASUS VG248QG works in stereo. I used the EDID that I posted here to make it work. The EDID you provided from the similar version, but 3D ready monitor did not work. Display was dark and inverted.
I don't know why that EDID I have from that old laptop works on two different monitors now. Seems like magic, I guess.
With the ASUS VG248QG, the recommendation is to turn on ELMB and turn off FreeSync. But that does not work for me with my EDID loaded, as it breaks the 3D vision.
Other users simply plug that monitor in, use those settings and it should work fine. I think most or all known users in that situation have a desktop setup. Mine (laptop) only works with my EDID loaded in Nvidia's settings.
Question: I manually load my EDID in Nvidia's system topology settings. Using the scripts and exe files from the 'black screen' workaround definitely works to stop the black screen effect, but it doesn't seem to load the EDID in the same way as manually loading it in Nvidia's settings.
It is the 3D capability that I am looking for, and not so much a custom resolution (but I assume that's a part of it, with the 119.x Hz). Loading it with Nvidia seems to give me the 3D. With just CRU and not manually loading it, that doesn't appear to happen.
If I manually load it in Nvidia, it stays there until I manually remove it. So problem mostly solved. It works.
Is this the correct procedure?
I created the exe file by loading the EDID manually in Nvidia's settings first. Then I found that monitor with CRU (which is now different from what it natively shows up as) and exported the EXE file. That's what I used in the startup script.
I tried booting without manually loading the EDID in Nvidia settings first, but it did not produce 3D.
The very best thing would be to have an option from CRU where the EDID does not have to be loaded from Nvidia's settings. Then I can run the EXE whenever I need to do 3D work.
This would save my computer from always thinking there is a monitor attached, when I don't need it.
Or, having some setting where you can set the laptop panel as the "main display" on system startup every time, even if an external display had that designation on shutdown.
For the program I use, whatever monitor is displaying 3D needs to be set as the main display, otherwise it will not activate 3D when you launch the program.
But, if you shut down, don't need the 3D monitor and re-start, Windows will treat the 'phantom' monitor as the main display until I manually change the setting.
Anyway... that's the whole story.
How can I contribute to your work? You have helped me a great deal. I would like to return the favor.
Sincerely,
Greg

You said you have two versions of the EDID. Is this the long one or short one? What is the other one? This one has a weird extension block that's basically empty and is interpreted as missing by CRU. NVIDIA will not load EDID overrides with missing extension blocks, so you need to delete the extension block to make it work with NVIDIA.
That was the short one. It is the only one that works for me (I have no idea why). The "long" one gives me an error when I try to load it with Nvidia.
Here is the "long" version, which I am pretty sure is what I originally pulled from my old laptop. It's been several years, so I can't be 100% sure.
