Custom Resolution Utility (CRU)

Yes, but sending a 12 bpc signal makes the images look so much more vibrant and colorful.

10 bpc looks a bit dull compared to 12 bpc.

This is the whole reason for wanting 444 @ 12 bpc. Otherwise i would not bother if there no clear difference between 10 bpc and 12 bpc.

and i have tested this thoroughly , i thought my eyes were fooling me. But there is a clear difference.

Then something else is changing because the bit depth doesn't affect color vibrancy. Maybe the TV is disabling some processing when it receives a 12 bpc signal.

In the extension block, in the HDMI 2.0 data block, what is the max TMDS character rate? It needs to be at least 1190 for 3840x2160 @ 100 Hz, but I don't know if HDMI 2.1 uses that information. It's normally 600 with HDMI 2.0.

Max TMDS rate is 300 Mhz.

But doesn't HDMI 2.1 higher bandwidth use FRL signalling?

In the HDMI 2.0 data block, not the HDMI data block.

Hey guys,

So I just got a new Xiaomi Curved 34" monitor + Nvidia 3060 ti.
When I open CRU I only get 3440x1440 @120 Hz resolution instead of @144 Hz. In Nvidia Control panel or windows display settings I can select 144 Hz though.
Is this considered to be normal? Shouldn't it be @144 Hz in CRU too?




I only edited the freesync range in CRU as I was trying to get rid of flickering. No other changes made.

Are you connected with DisplayPort? Your EDID may be missing the DisplayID extension block.

I also have similar issue, my panel(LG CX OLED) has 120hz native refresh rate, but i see only 60 hz in CRU detailed resolution.

Yes I'm connected with DP. How do I fix the missing block?
