Afraid not

This would be an NVIDIA driver bug then. Last I heard NVIDIA's driver ignores EDID overrides with certain displays such as the S95C, so this might also affect the S95D. Previously CRU wasn't able to read the extension blocks at all for displays affected by this issue, but you're able to read the first extension block, so I don't know if NVIDIA fixed that part or if the S95D is different. Technically the display has two more extension blocks that CRU doesn't list, but with the "Extension override" data block deleted, the EDID override is complete as you have it, so it's supposed to work. That needs to be reported to NVIDIA.

Understood, appreciate the feedback. I'll get a bug raised into Nvidia (not that I expect them to do anything). At least I know I'm not missing something obvious now

Any harm in leaving the 'Extension Override' gone, or am I best running a CRU 'Re-set-all' (assume that'll pop it back?).

Hello there. In CRU, under Extension blocks > Data blocks, there's a "Vendor-specific data" entry that cannot be edited. Is this safe to delete?

Hi Toasty, i've use this program on the same pc before, and its working fine, but when i reset the pc, somehow the cru program dont work anymore, in default i got 165hz monitor, but my pc only show 120hz, so i use cru to reduce the res and higher the refresh rate, its working well. But now, i try to do the same after reset pc, it wont work , maybe if u know there is some settings that i need to do to make it work? thanks

Details please. What monitor? What GPU? HDMI? DisplayPort? What does CRU show? What do you mean it doesn't work? Is it not listed in the Windows display settings?

Anything is safe to delete, but I don't know if anything uses the data. What is the vendor ID?

It doesn't matter since it's not taking effect anyway. Running reset-all.exe will bring it back, but since CRU can't read the additional extension blocks currently, it should be deleted when making an override. When CRU is updated to read the additional extension blocks, then it won't need to be deleted, but it shouldn't matter if it is deleted. Currently NVIDIA's driver seems to ignore EDID overrides from monitors with the extension override data block, so I haven't updated anything yet. I haven't decided how the UI should handle this because it's a confusing concept to have a data block override the main extension block count, but this is something the latest HDMI standard came up with for some reason.

This is what it looks like. Is this the ID you're asking for?

That's NVIDIA's ID. I'm not sure if it's used for anything. Maybe something to do with G-SYNC.
