Repeat - A6 - is working fine with same setting sand same cable and same connector HDMI-DVI-D. I don't have cable USB-C to DP, of course sure it'll be works fine, but need time for delivery it from Aliexpress and extra money for it. But as I said - the old A6 works fine with this connection.Normally AMD doesn't allow HDMI-DVI beyond 165 MHz without patching the driver, so if the A6 worked without patching the driver, then that's actually a driver bug. I can't guarantee that patching the driver will work on all models because sometimes certain limits only apply to certain hardware. The other way around the HDMI-DVI limit is to add an HDMI data block. If that doesn't seem to work, try unplugging and plugging the monitor in after restarting. If you get a USB-C to DP cable, you won't have to deal with these limits. |

Try including the range limits using the "Edit..." button at the top. CRU doesn't normally include that, and it shouldn't be needed for HDMI FreeSync, but maybe that's another driver bug. |

I cloned the EDID via the "copy" button for my LG C9 tv, and used the "paste" button to override the dummy plug EDID, but it doesn't appear to have any effect at all, even after restarting the driver and the computer. When I relaunch CRU, I see that the dummy plug shows up as having all the same EDID settings as the LG TV, but windows and nvidia control panel seem to treat it the exact same, with resolutions like 4k being locked to the dummy plug's original 17Hz, and even 1080p being locked to 30Hz. Is there some reason these features can't be overridden related to the nature of dummy plugs? I would assume you can set the windows registry to get the GPU to behave however I'd want since there should be no physical constraints to drive an actual monitor.The dummy plug is probably using a single lane with a low link rate just to emulate a barebones monitor, so there isn't enough bandwidth to do what you want. You would have better luck with an HDMI dummy plug, but the LG C9 uses HDMI 2.1, and I don't know if there are any HDMI 2.1 dummy plugs out there. There might be HDMI 2.0 dummy plugs, which would get you 4K @ 60 Hz at least. What are you trying to use the dummy plug for? |

The EDID is for the monitor, not the GPUs. The behavior you're talking about sounds like it's intentional by design. The laptop uses switchable graphics. |

I don't see that was the bag - A6 is from HP and driver was from it and was one more different: that driver showed the link speed in «Current link settings» of Display Specs — new drivers: «Current Link Settings — Not Available» |

After installing recent 21.6.1 package, it somehow fix itself. Thanks anyway. Although, freesync + frtc is still buggy with any version newer than 21.2.3, i.e. starting from the one, where devs got FRTC back to gui app. |

RE: Custom Resolution Utility (CRU)
Hello
I'm new to CRU and im trying to set an exact 120hz refresh rate my monitor when set to 120hz in nvidia control panel is 119.84 according to https://www.testufo.com/refreshrate I tried adding a detailed setting in CRU, using the "exact" option with: 2560x1440 and 120hz tried restart.exe and also a reboot of PC but no deal I must be missing something as I'm stuck on 119.84 |

This is what CRU shows me (and I could sworn in the top block it used to say 75hz too before the recent windows/amd updates). Adding it in attachments. Also images showing how the 75hz disappears once GPU scaling is selected. What CRU shows me after the GPU scaling change seems identical to before, under the extension blocks edit too (since I'm on HDMI). |
