Custom Resolution Utility (CRU)

[Osahashi]

Hello,

can someone please help me with the HDMI support? I have a 27MU67-B and a PS4 Pro, without any HDMI at CEA-861 the console runs not at 4K, I already change the cable.

The monitor use HDMI 1.2, the Nvidia driver is patched (if it makes any different).

I can add 3840x2160 at HDMI resolutions, but only 24 hz, 25 hz and 30 hz, not 60 hz? I think because my PC connects via DP and not HDMI, I can add a custom one, but only with a code that I didn't know.

What is ACP/ISRC? 30-bit deep color (10 bcp) is 10-bit color code right? Where is RGB, there is only YCbCr?

Default TMDS is 340 MHz, is that ok?

Is there any FAQ for the CRU tool or Wiki?

Edit: I know now what's the problem is, it's the HDCP! If I turn it off at the PS4 Pro the HDMI signal works with 4k and deep color, turn it on no signal. The monitor has in the service menu the setting "load HDCP", default is NO, maybe it works if I turn it on...
Can't turn it on, if I set it to YES it goes back to NO.
