I have tried deleting the greyed out “Default Extension Block” and restarted using Restart64 but that didn’t change anything. I have tried adding another one manually but it isn’t populated with any new data.

Am i supposed to add a new detailed resolution under the DisplayID section of my newly created Extension Block?

Like it says, the second extension block is usually a DisplayID extension block, but CRU can't read it, so it appears as a default extension block, and because of an NVIDIA driver bug, you will have to delete the default extension block and add a DisplayID extension block manually (use DisplayID 1.3). Then you have to add 3440x1440 @ 144 Hz in the DisplayID extension block.

Your screenshot shows 11 bytes left. If after fixing the extension blocks the range still won't change, try adding a FreeSync data block in the CTA-861 extension block. That's only 9 bytes, so that should leave 2 bytes left.

Thank you so much for taking the time to clarify this for me! It’s working beautifully now. You made my day. Thank you!

Hi,

I have the same monitor, same problem, and same goal. I tried to follow this but always ending up in recovery mode when applying the setting. I'm not much an expert in using this utility. It will much appreciated if you can share screenshots of the following for my reference:
- Adding of 3440x1440@144Hz in the DisplayID block extension (there are so many options to choose from and I don't know what actual values to select/enter)
- Values entered in the added Freesync data.

Thank you very much in advance!
