RE: Custom Resolution Utility (CRU)
I bought a displayport 1.4 to hdmi 2.1 cable to just see if i can solve my problem with my lg tv 4k 120hz and Radeon 5700xt. Has anyone here managed to get VVR or Freesync to work using the same combination?
I now have 10 bpc, full rgb 4:4:4 at 120hz and HDR but no VVR or Freesync. Whatever i try with CRU doesn't work. I can't get a custom 4k resolution to work whatever i tried even though according to amd software the connection is 8.1 Gps x 4. I'm still not allowed to go over 650 mhz pixel clock in the main screen detail resolutions. First extension block is detected now as hdmi 2.1 and if i add a DisplayId to add a custom resolution it works but it's not detected by windows drivers. Has anyone managed to get this to work? |

You need an adapter that is specifically designed to convert DisplayPort adaptive sync to HDMI 2.1 VRR. |

Still, it's strange that any custom resolution at 4k don't work. I can get custom resolutions at 2k but nothing at 4k with hdmi cable or with the adapter cable. |

What is the pixel clock of the resolutions you're trying to add? HDMI 2.0 has a pixel clock limit of 600 MHz. Is the driver still applying that limit with HDMI 2.1? That shouldn't even apply with a DisplayPort adapter anyway, so that would be a driver bug. |
