I know HDMI and DVI require at least 25 MHz. Strangely I just tested DisplayPort and HDMI with a GTX 1070 and the driver allows less than 25 MHz for both. I don't know about AMD, but I remember there being a 25 MHz limit. oh btw, i forgot to ask, does this mean nvidia lets you create 256x240 120hz resolution on CVT Timings using HDMI on your 1070??? even if it doesnt appear on the nvidia panel or windows node list, retroarch will let you switch to it if its truly compatible. |

What about if you add both 3840x1600 @ 60 Hz and 120 Hz? What about if you also add 3840x1600 with SRE: https://www.monitortests.com/forum/Threa...Editor-SRE Hello In the last few weeks I contacted NVIDIA. According to them, the problem is with the driver itself and has been fixed in the latest versions Well, I tested the last driver and again it is not working at the resolution of 3840x1600 at 120 Hz to be the native resolution, in order to use DLDSR If I don't use CRU and leave 3840x1600 as not the native resolution, not being able to correctly scale DLDSR, well, it works at 120 Hz normally Funny that the last driver to work perfectly is 556.12. I explained this to NVIDIA support but they don't seem to understand it well Now, am I going to continue with 556.12 forever? I tried everything without success Does anyone have any ideas? |

RE: Custom Resolution Utility (CRU)
Heya :)
Huge thanks to toasty for this tool, it's been super useful for CRT usage and has worked flawlessly in the past. Sadly, I'm having issues now with getting custom resolutions to work at all. Windows 11 24H2 Radeon RX 7900 XTX on latest drivers IBM C220p No matter what, I can't get any custom resolutions to appear in windows display settings. I can't set custom resolutions on AMD utilities either, so maybe it's not a CRU specific issue. I've verified that it's not a hardware issue, as I can force resolutions with xrandr on linux and it works perfectly. I tried the pixel clock patcher but that didn't help. I looked through previous suggestions of running edid-test, and here's the output: DISPLAY\DEFAULT_MONITOR\7&176FD83E&0&UID260 (active): 00 FF FF FF FF FF FF 00 41 D0 FF 09 00 00 00 00 00 00 01 03 08 00 00 78 EA EE 95 A3 54 4C 99 26 0F 50 54 00 00 00 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 A6 59 40 30 62 B0 32 40 40 C0 13 00 90 2C 11 00 00 1E F7 61 40 50 62 00 42 50 80 A8 37 00 90 40 11 00 00 1C 6D 8E 80 E0 72 00 4F 60 A0 D0 37 00 E0 80 11 00 00 1C 7F 84 00 00 83 00 46 60 A0 E0 34 00 00 80 21 00 00 1C 00 C1 Override: 00 FF FF FF FF FF FF 00 41 D0 FF 09 00 00 00 00 00 00 01 03 08 00 00 78 EA EE 95 A3 54 4C 99 26 0F 50 54 00 00 00 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 A6 59 40 30 62 B0 32 40 40 C0 13 00 90 2C 11 00 00 1E F7 61 40 50 62 00 42 50 80 A8 37 00 90 40 11 00 00 1C 6D 8E 80 E0 72 00 4F 60 A0 D0 37 00 E0 80 11 00 00 1C 7F 84 00 00 83 00 46 60 A0 E0 34 00 00 80 21 00 00 1C 00 C1 Another thing of note is the display is marked with (restart required) in CRU, even after I restart. Guidance on how to troubleshoot this would be greatly appreciated! |

Thanks for reaching out :)) VGA cable with a VGA-to-DP adapter (StarTech DP2VGA3) Is there some way to spoof a valid EDID? |

Likely the monitor's EDID is corrupted, or it's not sending an EDID, or the cable is missing the DDC pins, or the adapter is not passing through the EDID properly. Problem is without a direct VGA connection, it's hard to check if it's the monitor. Are you able to read the EDID with this? https://www.monitortests.com/forum/Threa...yID-Writer |

I don't want to take up too much of your time, but one more thing of note: when I use a DVI cable instead, with a DVI-to-DP adapter, I think a valid EDID does go through, as I can see the monitor name and correct presets in CRU (the only issue there is no analog output to the monitor with that cable/adapter). Does this narrow this down to a cable/adapter issue, and if so, would a hardware EDID emulator solve the issue? |
