Generally you shouldn't need to change the features because if the display supported them, they would already be available, and I don't think those features are supported with PC drivers anyway.

The issue is DisplayPort dummy plugs are usually just single-link DVI dummy plugs with a different connector, like a passive DisplayPort to single-link DVI adapter, so they should be limited to 165 MHz pixel clock.

That leaves four possibilities:

4. The dummy plug is actually DisplayPort, and Intel is incorrectly limiting the pixel clock for some reason. With real DisplayPort, 6 bpc color is usually available as an option, while DVI can only be 8 bpc.

DisplayPort and DVI don't need anything special in the EDID, so you can just delete all the resolutions and extension blocks and just create the resolutions you want. 1920x1200 @ 60 Hz with "Automatic PC" timing should work in all cases since that does not exceed 165 MHz pixel clock.

Thank you for the above feedback. I can't be certain if the dummy plug is actually DisplayPort or as you said possibly just single-link DVI dummy plugs with a different connector.

I'm just looking to putback the 1920x1200 @ 60 Hz, that's all. I only use 1920x1080 and 1920x1200 both @ 60Hz. These dummy plugs allow me to connect to PC1 and PC2 using the VNC from my other PC with physical monitors that are mix of 1920x1080 and 1920x1200 @ 60Hz.

So, "if" Intel behaving "oddly" for "some reason", then how does your suggestion of deleting all the resolutions and extension blocks and just create the resolutions i want from CRU will (hopefully) solve my mystery? Maybe just a quick explanation on how this can work under the hood?

And as for the steps, do i perform following steps in this order?

a) Delete All the Extension blocks?
b) Delete All the Standard resolutions
c) Delete All the Detailed resolutions
d) Add to Standard resolutions (only add to here ???) the two resolutions @ 60 Hz? Or (also ???) add to the Detailed resolution using Automatic PC Timing?
e) Reboot (or restart64.exe ???)

I do see the 1920x1200 listed in the Standard resolutions so not sure how Intel is getting confused, somehow.

I explained that already. Normally standard resolutions are not reduced blanking, so 1920x1200 @ 60 Hz would exceed 165 MHz pixel clock. 1920x1200 @ 60 Hz with "Automatic PC" timing should work in all cases since that does not exceed 165 MHz pixel clock.

Don't think so hard. Just delete everything and add 1920x1200 and 1920x1080 @ 60 Hz as detailed resolutions with "Automatic PC" timing. That's it.

Yep, that was it. Thank you!

I just suspect a raw fw, this is an OLED monitor on an LG Oled Gen 3 display. I think it should support this.

Hello toasty i need help, i built a new computer and i cant get my crt to display a picture with the generic HDMI to VGA adapter i was previously using.

old pc: Gigabyte Z390UD , i3 9100 , 2x8GB ram 3000mhz , igpu.

Current build: Asus Maximus Rog XII Hero wifi, i9 10900K , same ram, iGPU.

the generic hdmi to vga adapter was able to comfortably render 1920x1200i 144hz , 1920x1440i 120hz , my new motherboard only has an HDMI output, what am i doing wrong? or maybe i cant use the generic adapter to use my samsung 997MB at all on this motherboard??? i have tried deleting everything on CRT to make sure that only 1920x1080p 60hz cvt standard resolution is left for the 997MB , but it wont show a pic at all, it just blackscreens.
