what should be my next step?

You edited the 60 Hz detailed resolution. Edit the 75 Hz detailed resolution.

I don't have a 2560x1080 75Hz detailed resolution. After a reset-all there is just a 2560x1080 59.999Hz and a 1920x1080 60Hz, exactly as you see them in the screenshot

So here an issue that i have had for a while, (2019) my laptop display on an Hp had lost its HDR display VESA Certification after some sort of graphics Issue
i think is a SDCA029 Amoled (400 true black hdr) as it's internal monitor)
Spectre x360 df100 CTO 15
intel i7-9750, and nvidia gtx-1650
internal DisplayPort 1.4
(Intel command center says it can't natively stream dhcp content unless hdr was enabled
through Intel graphics uhd 630 adapter

and now wont stream (but other displays do) in while it does the windows HDR, it only displays 8bit color depth as apposed to its "original out of box" 10 bit depth HDR

Is there any way i could use the the Custom Resolution Utiility restore the to its original state.

any help would be much (possibly anyone with the same display provide exported monitor data of, or basic setup to restore functional Display Hdr

Updated, exported the monitor setup data to view in an edid editor hdr ranges are there, (checked against the displayhdr specs, it's displaying 10 bit hdr but it's not being interpreted by the machine as 8bir sdr

Any help would be appreciated

Hello.

I have a Samsung Q70T tv, which is a 4k 120hz native TV via HDMI 2.1 with VRR, which supports Gsync compatible via NVCP.

While I do have a good HDMI 2.1 cable, my GPU is a RTX 2080, which sadly doesn't have HDMI 2.1 output, only HDMI 2.0

I'm trying to setup the TV as a UltraWide resolution, and while I can get native 3440x1440 @ 60hz, 3440x1440 @ 70hz with custom NVCP resolution and even 3840x1607 (which is nice as I then can disable scaling) @ 70Hz via NVCP, I can't figured out how to get 100mhz, which from my research should be supported by HDMI 2.0 at 3840 or 3440 resolutions

I did a few tries with CRU via Detailed Resolutions testing different modes for timing, none worked with 100hz, not even 75hz I can get to work.

If anyone has any experience with something similar and could share some ideas / configs I need to try, I would appreciate.

Thanks!

You can use the DP 1.4 -> HDMI 2.1 adapter, which works great with CRU.

Not sure if links are allowed but just in case you can just search "Club 3D DisplayPort1.4 to HDMI 4K 120Hz HDR Active Adapter M/F CAC-1085" they have it on amazon and other stores.

I have 2080ti's and works great there, though running at 100mhz for 4:4:4/RGB @ 8bit, I think I need to get a shorter cable despite using a 10k cert cuz its 2 meters, since if I run 120hz I drop to 8bit ( still 444 or RGB though )

Though curious if there's any q90t owners on the thread that have managed to customize a res to fit within the 1075pixel clock I tried the LG ones but they just blank out the screen to no signal.

Thanks but sadly that adapter is not available in my country and it would cost an absurd amount of money to import it.

The problem seems to be solvable adjusting the configuration of CRU as AMD can't do that correctly. But I don't know how to improve it.

Try reducing the blanking/totals.

I have tried all the posibilities and settings, with new drivers, with lenovo drivers (they are older version without Adrenalin interface). If I reduce more the blanking/totals I get a slow behaviour like slow motion.

The setting that "works" is "Exact reduced" and pushing restart driver when screen start to flickering again.

Definitively I give up.

Thanks a lot for your time and helpfull.

Did something change in the 'recent' NVIDIA drivers that affects this tool?

I've been using it for years, always adding detailed resolutions for my monitors (currently 34GK950F), but now none of the changes I make in the tool are taking effect.. when they used to before I updated my drivers to the most recent ones at time of writing. Was using a driver about ~5 months old before this.

If I follow along with deleting the default extension block, it completely screws up the resolution list, throwing a bunch of resolutions into a separate section in the NVCP and only showing 60/75/100Hz for the other resolutions (including native), when there should be 120/144Hz as well.

And it's also showing a duplicate non-present monitor in the list, which re-adds itself after being deleted (either via device manager or CRU) and restarting the driver.

I don't know what the hell is going on, but adding a custom resolution in NVCP works as expected, almost like CRU used to (shows as a "custom" resolution instead of a native one).

For whatever reason after following the guide on how to make 120hz setting, I lost the ability to set 4:4:4, I tried reset-all to no avail, Even DDU'd and reinstalled GPU drivers but I no longer have the option in NCP, Just 420 422 and RGB, reason I'm asking about 444 is because for w/e reason on RGB Text looks slightly thinner/jagged, vs 444, despite being on RGB Full.

Any suggestions on how to get 444 back would be greatly appreciated, using a 2080ti.

I don't see how. Nothing should persist after using DDU.
