The native resolution affects how non-native resolutions are scaled, but that wouldn't be an issue for the AVR since there is no display, and you can change the native resolution with CRU anyway. Just make sure the AVR is set to a resolution with enough blanking to transmit the audio.

The audio data block in the CEA-861 extension block lists the supported audio formats.

I assumed that would be an issue for DSR, but, weirdly, even without changing the native resolution, DSR still factored its multiples with 4K as the base.

Anyway, there were two identical "default" resolutions of 720 x 480 @ 59.940 Hz listed, with the Denon AVR as the active "display" (GPU connected to it).

I removed one of them and, using the same back porch (60 x 30) and blanking (138 x 45) as the default ones, added two others: 3840 x 2160 @ 60 Hz (first slot on the list) and 2560 x 1440 @ 120 Hz (second slot on the list). One of the original 720p resolutions is now the third slot on the list. Questions:

1. Did I do that correctly?
2. Is changing the native resolution done by simply moving the detailed resolutions up and down on CRU?

Edit: For some reason, whenever I power on my PC or restart it, the color settings default to RGB 8-bits, and I have to change them every time to 422 12-bits. So:

3. Any idea why?

Also, I tried to add a fourth detailed resolution (to the only remaining slot), but that caused issues with audio. It only resumed playing once I cleared the fourth slot, no matter what resolution it included.

4. Even if there are four slots, I have to leave one "open"?

Right!

5. Do I just copy the info presented there when the Denon AVR is the active "display" and add it to the same extension block after the LG TV becomes the active display?

I really appreciate your help.

I would just use "LCD standard" for TV resolutions like 3840x2160. For 2560x1440, use whatever timing parameters the TV defined. 2560x1440 is not a TV resolution, so the standard timing parameters might not provide enough blanking for all audio formats.

The first detailed resolution is the native resolution.

That would have to be an NVIDIA driver bug.

What's in the fourth slot? Is it the monitor name? I remember NVIDIA's driver had a bug that broke the audio if the monitor name wasn't included. That's not a problem with AMD.

Yes, you can do that.

When I first added 3840x2160 as a detailed resolution, in order to make it the Denon AVR's native resolution, I ended up with two similar resolutions on NVCP: "4k x 2k, 3840 x 2160" under "Ultra HD, HD, SD"; and "3840 x 2160" under "PC".

Now that I edited the timing of that detailed resolution, changing it from "Manual" to "LCD standard", as you instructed, the "3840 x 2160" resolution under "PC" disappeared. Is that the intended behavior?

Also, how do I find out the timing parameters that the TV defines for non-TV resolutions, like 3200x1800 (60Hz) and 2560x1440 (120Hz) - the two extra resolutions that I want to add?

Got it!

Weirdly, it only started after including the extra detailed resolutions via CRU. I'll update my drivers tomorrow, and will let you know if it keeps happening.

It is, indeed, the monitor name - or, rather, the AVR's ("Name: DENON-AVRHD"). That explains it, then. Can't have more than three detailed resolutions on Nvidia, even if there are, technically, four slots.

Great!

Thank you, as always, for the help, @ToastyX.

That has nothing to do with CRU. CRU does not implement FreeSync.

I fixed issue in games by disabling response time of monitor. In firefox videos still goes to blank if hardware acceleration is enabled, if i disable it it works as usual. Which HDMI 2.0 features to enable?

Actually I didn't fix it, monitor goes black when I play games with Freesync on.

Then return the monitor. FreeSync should work out of the box on FreeSync monitors. CRU can't fix a monitor that doesn't handle FreeSync correctly.

The distinction is specific to NVIDIA's driver. The CEA-861 standard defines the timing parameters for digital TV resolutions, so NVIDIA's driver probably lists any resolutions matching the standard in the "Ultra HD, HD, SD" section. 3840x2160 @ 60 Hz with "LCD standard" matches the CEA-861 standard. There might also be TV resolutions defined in the extension block that are included in the list.

CRU should show you what the TV defines in the EDID. 3200x1800 is probably a scaled resolution automatically added by NVIDIA's driver, but 2560x1440 @ 120 Hz should definitely be one of the detailed resolutions. There are more detailed resolutions in the extension block.

My PC is connected to the my new 4k TV using the HDMI 2.0. When I go into the resolution settings in Nvidia graphics panel it says native resolution is 1080p but allows me to choose 3840x2160.

I have 4k tv why does it say 1080p as native? I have reinstalled driver using DDU but still problem persist. Any idea how to fix it? Before i had this graphics card connected to my old 1080p tv. @ToastyX or anyone else would be able to help me out.

The first detailed resolution is considered the native resolution. You can change that with CRU.

Thanks, Any idea why 1080p is in the detailed resolution of a 4k tv.
4k resolution was in the extension block so i copied the value to the detail resolution.
