I’m really sorry if I seem ignorant or uninformed but this is all very new to me and quite overwhelming. I’ve read the extension block information in the first post but I’m still not sure what to do.

Again, here is what I see with my monitor:



There is no 3440x1440@144Hz under detailed resolutions and I can’t find it under Extension Blocks either. There are no DisplayID extension records.

NVIDIA also does not support default extension blocks, so delete any default extension blocks and add one manually if needed. The second extension block is usually a DisplayID extension block with detailed resolutions greater than 655.35 MHz pixel clock such as 1920x1080 @ 360 Hz and 2560x1440 @ 165 Hz.

I don’t understand how I am supposed to access any potential second extension block containing additional detailed resolutions? 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?

• Extension block types:
  • CTA-861 extension blocks can contain additional detailed resolutions and data blocks such as TV resolutions and HDMI support. Note: NVIDIA requires at least 2 bytes left for data blocks or the driver will ignore all changes.

I’m not sure how to confirm if there are at least 2 bytes left for data blocks in order for my Nvidia card to not ignore the changes I make?

All in all, i have read all the information in the first post numerous times but I’m still not sure how to reach my objective:

To limit the adaptive sync range to 80-144Hz when using my monitor in 3440x1440@144hz.

I’m sorry if I’m thick but any help would be greatly appreciated.
