Second "Check the extension blocks and the TV resolutions and HDMI data blocks." i dont know to do that, can you give me some instructions?

I told you, use CRU to delete 3840x2160. There should be an extension block. Edit that. Check the TV resolutions and HDMI data blocks for 3840x2160.

The default extension block is empty, cant see 3840x2160 anywhere, only in control panel in windows we see that resolution.

"Check the TV resolutions and HDMI data blocks for 3840x2160" in what file i can find that ?

Thank you

It didn't work, I have added it to all the monitor profiles listed in CRU but still it is overscanning and grainy.

If you don't need HDMI audio, delete the extension block.

Then delete the extension block. I don't know why it's not showing the extension block for you, but 3840x2160 is probably in there.

There isn't an extension block of any sort, should there be? on the old gpu it worked without them.

Great help, thank you, i deleted the tvresolutions in the block, and know it works, i can set the surround with 7680x1440.

Thank you very much for your help.

Since it seems like my question was not responded to, I'll ask a similar yet different question that should be less blunt and easier to answer:

Is there any way for CRU to create a curstom resolutions over 600MHz for HDMI 2.0 connections?

I understand that it's out-of-spec, but there are physical products being sold today like the LG CX that have out-of-the-box support for 4k 120Hz 4:2:0 8bit over HDMI 2.0 without any need for a custom resolution, and people are simply trying to find a way to feed it a slightly lower refresh rate (such as reduced blanking 100Hz) so as to free up enough bandwidth in hopes of enabling 10bit HDR.

4k 120 Hz 4:2:0 is still under 600 Mcsc. I don't have a way around the 600 Mcsc limit.

Then try changing the detailed resolution to "LCD reduced" timing.
