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.

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?

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.

I see. That makes sense, thanks for the explanation.

I performed a clean installation of the most recent drivers (436.15), using DDU, and went through the entire process with CRU again, first collecting the TV's EDID with the GPU connected directly to that display.

The TV itself only has two "main" detailed resolutions: 3840x2160 @ 60Hz and 1360x768 @ 60.15Hz. There are a bunch of standard resolutions (all 1080p and below) and one extra resolution in the extension block, of 2560x1440 @ 119.997Hz.

Marked down the timings of the two resolutions that I wanted and added them as an override to the Denon AVR, with the GPU connected through that device. This is what they looked like:

3840x2160 @ 60Hz
2560x1440 @ 119.997Hz

This is what the DENON-AVRHD "display" now looks like in CRU. There are no detailed resolutions and also no space left in its extension block, so I couldn't change anything there.

I have some final questions:

1. Do my settings look right to you?

2. I still haven't added the 3200x1800 @ 60Hz resolution, because I don't know what to include as its timings, would you mind helping me with that?

3. The issue that I mentioned before, where the Nvidia color settings keep reverting to RGB/8 bpc, is still happening, even after a clean installation of new drivers. It started only after using CRU, is there a setting that I can change to fix that?

That looks fine. 2560x1440 @ 119.997 Hz looks the same as what "LCD standard" would fill in. I figured maybe it would need larger horizontal blanking for some audio formats to work, but maybe not.

You shouldn't need to add it if it's one of the scaled resolutions that the driver adds automatically. If you do need to add it, start with "LCD standard" and increase the horizontal blanking if some audio formats are missing.

That has to be a driver bug. The driver is supposed to remember the color depth. CRU can only define what color depths are available (in the HDMI and HDMI 2.0 data blocks).

Hello!

Got a new monitor today (Samsung LU32J590UQUXEN 32-Inch 4K Ultra HD 3840 x 2160 LED Monitor) and native resolution doesn't allow me to use 3840 x 2160. Have tried using your tool, however, it's still not showing the detailed resolution within my windows list - any ideas?

I've got my laptop plugged in via a Dell DisplayLink, which is 4K itself - so not sure that would be the issue.

Thank you!

You need HDMI 2.0 or DisplayPort 1.2 to get 3840x2160 @ 60 Hz. DisplayLink does not support EDID overrides and will not work with CRU.
