YCbCr 4:2:0 resolutions are defined in the CTA-861 extension block in a 4:2:0 resolutions data block, which you can add by adding a TV resolutions data block and enabling the "4:2:0 resolutions" option. Windows will only list the resolution if the GPU driver supports it. |

It did https://i.imgur.com/tDl6Q9L.jpg https://i.imgur.com/Zpq8LUC.jpg But because there is a color depth bug when modifying from Radeon Software so I looked up CRU And that's what I saw CRU can't have multiple settings like in the picture After setting, it can't override the default settings of the system (60.0-60.5→60), or specifically separate out (59.5-60.0→59), no options at all, it's just ignored. I also tried Run as administrator and it did not work Perhaps the original design of CRU does not take into account the above situation So I would like to ask if this feature is possible in the future Or is this actually a bug? |

Radeon Software custom resolutions lets you specify which integer refresh rate to list as, even if the actual refresh rate doesn't match. CRU is an EDID override tool. There's no way to do that with EDID overrides. Refresh rates in the [59.5-60.5) Hz range are considered the same by Windows. |

I will try, unfortunately the intel the hd500 like all intel graphics chips up to the new uhd700 series only supports 30hz on hdmi in 4k, I wanted to try to understand if by lowering the bandwidth it was possible to solve this problem since the graphics chip actually supports 4k 60hz on display port (which i don't have on my mb) |

Some reported issues since 471.11, but that was a system freeze, not just a black screen. As for the TV, there's no way to add FreeSync to a display with NVIDIA. NVIDIA does not support HDMI FreeSync, only HDMI 2.1 VRR. Thank you for your reply Yes, changing literally anything causes a black screen, and if I remember correctly, a system freeze, forcing a manual restart. I've tried 3 different drivers from January and February, same result. Oh well, guess I'll try Scanline Sync or just use VSYNC on the HDMI TV then. |

RE: Custom Resolution Utility (CRU)
Hello everyone. I recently setup everything to stream from my gaming rig to my LG 4k TV which supports HDR. I got a Lindy 32014 edid Emulator ( https://www.lindy.de/HDMI-10-2G-EDID-Emu...pi=32104). The manufacturer says it supports emulating an HDR signal, but in fact you need another device to emulate HDR.
I tried messing around with CRU, adding a block with HDR information, trying various settings. But it had no effect. Is it possible to to what I am trying and if yes, how can I achieve that? Kind regards |

I saw several programs for editing Edid data, but I never heard that this standard exists before, so I have absolutely no clue what's possible with that, if there is a pure software solution, or if further hardware to rewrite the edids eeprom is needed. |

There must be some sort of information in the video signal. |
