I have an Ryzen 4700U. Is this normal?

No, that's not normal.

Any thoughts on how to fix it?

Steps I took in CRU:
1. Imported HDMI2.dat
2. Click Edit CTA-861
3. Add FreeSync range: 40-60Hz
4. Reset64.exe

My monitor is an LG 27UK650-W which supports that freesync range.

Thanks!

You shouldn't have to change anything if the monitor supports FreeSync.

I don't know what you mean. What device are you using for audio? Normally you shouldn't have to add Dolby Digital if the device supports it.

Using an RX6800 GPU with HDMI 2.1 Output to an LG C9 with ARC (no eARC, thats why i need the compressed format) to an AVR

Thanks so much for this useful utility! I had a question about modifying HDR static metadata.

What exactly does Max luminance, Max frame-avg, and Min luminance adjust? Max and min luminance seem to affect maxCLL/minCLL but do they also change maxTML/minTML? Max frame-avg is maxFALL? Is there any way to adjust maxFFTML?

Thanks again.

Like JasonMT ... as well as me and some others from the ComputerBase Forum and the AVS Forum are currently interested in these values that can be set in the CRU.
Since our monitors / TVs are not recognized by Windows with regard to the nits, Windows uses default values ... with the OLED instead of 800 nits Peak , Windows then takes 1499 nits Peak as a value ..
but that's wrong. Fortunately, we can use your tool to adjust the values manually. So .. now we are faced with the problem that we do not know 100% what exactly is which value.

Max Luminance
Max Frame AVG
Min Luminance

But now the "Max Luminance" value has an influence on the "Max Effectice Value" as well as on "Max Peak Luminace"
And "Max Frame AVG" influences "Max Fullframe Value" and "Max Frame Average Luminance"

You can check this quite well with the "VESA DisplayHDR Test" tool. I'll upload a picture where I showed it.

The question that interests me the most at first is whether
"Max Frame AVG" is the nits value that the device creates with a 100% white picture or whether it is the nits value that refers to the "Max brightness of all pictures on average" ?

This is the relevant standard for HDR static metadata: https://shop.cta.tech/products/hdr-stati...extensions

I don't have any other information beyond that.

hmm ok ... ok then let's take a look at this.
Maybe that will help us a little further.

Thank you for your quick reply.

Just noticed the following CRU related bug in Win11, for the Nvidia control panel:

After making changes in CRU and rebooting, the whole "display" section is missing from the nvidia control panel.
Deleting any changed profile from CRU and rebooting restores the "display" section

I am currently on win11, with nvidia driver ver 496.49

Is there any reason to add missing Colorimetry if the EDID doesn't have them checked (for example, on my set, only BT.2020 cYCC and BT.2020 YCC are checked)?
