Try this: lg-cx-48gbps-vrr.dat (Size: 985 bytes / Downloads: 679) |

If it's stable after changing the range with CRU, then it might be a driver bug. The buggy firmware on the monitor could be causing an unstable or incorrect DisplayPort signal that the driver is not handling correctly. I don't think audio has anything to do with the problem. Since the monitor also has HDMI, it might be worth checking to see if the problem also happens with HDMI. |

Apologies for being brand new to this. I just tried your original file and when I import that, a “Range limits” field appears in the “Detailed resolutions” section. When I try to import the new file, I don’t see any changes taking effect. I might just be missing something, anybody know what it could be? |

CRU can't edit this value yet, so it's not visible. The next version of CRU will include HDMI 2.1 parameters such as the maximum FRL rate, variable refresh rate, and display stream compression. |

Ah, makes perfect sense, thanks for the explanation. |
