iiYama monitor recognized as HDMI-HDTV and not PC

My second monitor is connected via HDMI. RTX 3060 recognizes monitor as a HDMI-HDTV. Customised the output dynamic range to 'Full' but the screen is still not as crisp as when it was connected to intel HD graphics.

My current feel, after trying all sorts of excellent suggestions, is that nvidia does not see the monitor as 'PC' and the screen remains unsharp. Whilst my first monitor also displays resolutions for Ultra HD, SD etc, it also displays resolutions for PC, which i selected of course.
How can i update the Nvidia driver to address the monitor as a 'PC' ?
Thank you!

 

maybe start by downloading the proper driver file for your Iiyama monitor look up the type on their website

it should look like this in device manager

 

monitors don't have "drivers."
the inf can override the edid specified resolutions (nearly none of them do) and install typically poorly made icc profiles.

 

Yeah icc profiles are good enough but outdated

 

I already tried this (see picture), but it does not make any difference. The NCP does not recognize this monitor as a PC.

 

Is there anybody who could help me out, how to let nvidia NCP think the second monitor is not a HDTV?
A registry setting perhaps?

 

Have you tried a different HDMI cable? Isn't there a setting in Windows somewhere

 

Try editing your monitor's EDID using CRU: https://www.monitortests.com/forum/Thread-Custom-Resolution-Utility-CRU

 

^CRU will have a section for TV and TV resolutions. Delete every one which will remove the section. Persists through driver updates.

I bet your DLDSR\DSR values are screwed up too.

 

Thank you! The output of the CRU 2790 is the monitor that only has TV resolutions. The 2893 is the 4K monitor that is ok.
What do i need to delete?

 

Double-Click on the "CTA-861..." entry, it should open a Window with various things. One of them should be "TV Resolutions", double-click on that. You can also check under "HDMI Support" and see what's listed there.

 

This is the output of the two questions. Thank you again. What do you advice to change or delete?

 

I don't know about your particular monitor. It's odd that your HDMI Support section doesn't show any HDMI resolutions in the bottom. Perhaps you could try to add the monitor's native one there and see if it helps?
If you have standard and detailed resolutions listed on the first CRU page, then you could probably try to delete all the TV resolutions and see what happens. Keep in mind that you may have to to reset it in Windows safe mode (either use CRU's reset-all.exe or you can also use DDU with the removal of monitors ticked in Settings there - which may be a good idea to try anyway in case there are any conflicts from previous monitors) if you lose sync due to it, though.

 

What i have done is i removed the HDMI support in full and i have deleted all tv resolutions.
In NCP the connect is suddenly changed to DVI (and i can select resolutions in both PC and HD etc mode).
I suppose this is because i deleted the HDMI support line.
Btw: all of these actions have NO EFFECT :-(
What i also noticed is that in CRU i can change the timing for a particular resolution (for example to: automatic PC) but if i ok the change and reopen the resolution again, it is back to manual again.
Btw2: I tried to add the native resolution in the HDMI support section (that i now removed), but it requires a binary code for other resolutions than the two displayed. Neither is supported by my monitor. I suppose i need to know the binary code (0-255) for 1920x1080@60Hz?
Any next suggestions are welcome. It is just amazing i can change so many things and see no difference.
