The cheap laptop I used to try and get EDID from projector and LG TV is some built GPU in, no idea - what difference does GPU in laptop make? I can't haul gigantic heavy gaming PC from upstairs office to downstairs living room to plug directly into projector. |

RE: Custom Resolution Utility (CRU)
So I have the new PG27AQDP
I tried editing the HDR override so that the min luminance is null. I've kept DSC on so I can get the full 480hz. But it seems that it doesn't save, even after restarting. Is this expected behavior? Is it a limitation of the monitor itself or something Nvidia has done? |

The GPU matters because CRU gets the extension blocks from the graphics driver, and it can only read extension blocks with AMD and NVIDIA GPUs because Intel wouldn't provide access to their SDK, so if the laptop has an Intel GPU, CRU can't read the extension blocks, which is where the 4K and HDR information would be. Further complicating this is newer HDMI displays have another way of defining extension blocks that CRU doesn't support yet, so there might be another extension block that CRU can't read, and NVIDIA's driver will ignore EDID overrides for displays with DSC if the pixel rate is beyond a certain point. I have a new way of reading extension blocks that should work with Intel GPUs, but I can't easily integrate it into the current version of CRU because it's stuck on an old compiler because of the UI library, so I'm in the middle of rewriting CRU from scratch with better designed code so I can deliver all the updates and features that I've been wanting to add. Run this and post the edid-dump.txt here: https://www.monitortests.com/edid-dump.zip |

Has this always been the case (perhaps there’s an older driver that doesn’t ignore EDID override)? Just seeing what my options are. It’s really frustrating as the min luminance should be 0, but the monitor’s EDID is showing 3. And RTX HDR reads the EDID. |

Oh right... I didn't realize that the host PC hardware was important to actually read EDID correctly. I presume it's in documentation somewhere - I didn't read any docs. Probably would be a good idea for the program itself to say this to user and give them warnings/errors messages about not being able to read and requiring a NVidia GPU etc. Laptop (ACER Aspire 1) has the inbuilt Celeron N4000 CPU graphics only it seems (Intel UHD graphics it just says). I plugged into both LG 55" CX OLED and the Sony VPL-VW360ES projector and ran EDIDDump: Sony VPL-VW360ES (SNY6004) DISPLAY\BOE06BD\4&2F7DD359&0&UID265988: 00 FF FF FF FF FF FF 00 09 E5 BD 06 00 00 00 00 01 1A 01 04 95 1F 11 78 02 24 10 97 59 54 8E 27 1E 50 54 00 00 00 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 3E 1C 56 A0 50 00 16 30 30 20 36 00 35 AD 10 00 00 1A 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 FE 00 42 4F 45 20 43 51 0A 20 20 20 20 20 20 00 00 00 FE 00 4E 54 31 34 30 57 48 4D 2D 4E 34 31 0A 00 22 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 DISPLAY\SNY6004\4&2F7DD359&0&UID198147: 00 FF FF FF FF FF FF 00 4D D9 04 60 01 01 01 01 00 17 01 03 80 E0 77 78 0A 99 55 AE 51 49 B2 24 0D 50 54 21 08 00 90 40 81 80 81 40 01 01 01 01 01 01 01 01 01 01 02 3A 80 18 71 38 2D 40 58 2C 45 00 00 00 00 00 00 1E 0E 1F 00 80 51 00 1E 30 40 80 37 00 00 00 00 00 00 1C 00 00 00 FD 00 17 3F 0F 44 2D 00 0A 20 20 20 20 20 20 00 00 00 FC 00 53 4F 4E 59 20 50 4A 20 20 2A 30 34 0A 01 DD 02 03 47 B0 50 62 64 63 5D 5F 5E 10 1F 20 05 14 04 13 03 12 01 78 03 0C 00 10 00 B8 3C E0 31 FF 31 FF C8 86 01 02 03 04 01 40 19 C0 90 A0 67 D8 5D C4 01 5A 80 03 E3 05 E3 01 E2 00 FB E5 0E 66 65 61 60 E3 06 0D 01 02 3A 80 D0 72 38 2D 40 10 2C 45 80 00 00 00 00 00 1E 8C 0A D0 8A 20 E0 2D 10 10 3E 96 00 00 00 00 00 00 18 8C 0A D0 90 20 40 31 20 0C 40 55 00 00 00 00 00 00 18 00 00 C7 LG 55 CX OLED (GSMC0C8) DISPLAY\BOE06BD\4&2F7DD359&0&UID265988: 00 FF FF FF FF FF FF 00 09 E5 BD 06 00 00 00 00 01 1A 01 04 95 1F 11 78 02 24 10 97 59 54 8E 27 1E 50 54 00 00 00 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 3E 1C 56 A0 50 00 16 30 30 20 36 00 35 AD 10 00 00 1A 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 FE 00 42 4F 45 20 43 51 0A 20 20 20 20 20 20 00 00 00 FE 00 4E 54 31 34 30 57 48 4D 2D 4E 34 31 0A 00 22 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 DISPLAY\GSMC0C8\4&2F7DD359&0&UID198147: 00 FF FF FF FF FF FF 00 1E 6D C8 C0 01 01 01 01 01 1E 01 03 80 A0 5A 78 0A EE 91 A3 54 4C 99 26 0F 50 54 A1 08 00 31 40 45 40 61 40 71 40 81 80 D1 C0 01 01 01 01 08 E8 00 30 F2 70 5A 80 B0 58 8A 00 40 84 63 00 00 1E 6F C2 00 A0 A0 A0 55 50 30 20 35 00 40 84 63 00 00 1E 00 00 00 FD 00 18 78 1E FF 77 00 0A 20 20 20 20 20 20 00 00 00 FC 00 4C 47 20 54 56 20 53 53 43 52 32 0A 20 01 66 02 03 64 F1 5E 61 60 76 75 66 65 DB DA 10 1F 04 13 05 14 03 02 12 20 21 22 15 01 5D 5E 5F 62 63 64 3F 40 2C 09 57 07 15 07 50 57 07 01 67 04 03 6E 03 0C 00 20 00 B8 3C 24 00 80 01 02 03 04 6A D8 5D C4 01 78 80 53 02 28 78 E2 00 CF E3 05 C0 00 E3 06 0D 01 E2 0F FF EB 01 46 D0 00 48 03 76 8A 66 72 7C 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 2E I presume BOE06BD in both is the laptop |

RE: Custom Resolution Utility (CRU)
I have been trying to use CRU to add resolutions to a 3440x1440 monitor to no avail (I cannot see the custom resolution in the Windows resolution settings). I am trying to add the resolution 2734x1824.
I have tried adding this resolution multiple times using different methods. I've added it to every single entry (Display1.3, Display2.0...) and it doesn't work. I've also added it to detailed resolutions and it doesn't work. And yes, I have tried both restarting my GPU using the given exe, and in fact I even tried restarting my computer, all to no avail. Does anyone know what the issue in my case might be? Also, I use an Intel UHD 620 for graphics. I have tried the export method already. |

I presume it's in documentation somewhere - I didn't read any docs.There are too many driver-specific issues and hardware limitations that I can't easily check for. CRU lists "Default extension block" if an extension block can't be read. This won't be an issue after the rewrite anyway. You can copy the EDID you want into a text file and import the file using CRU. The projector is DISPLAY\SNY6004\4&2F7DD359&0&UID198147. Keep in mind every dummy plug I've seen so far only really supports HDMI 2.0 TMDS even if they claim to be 4K/8K (they use YCbCr 4:2:0 for 4K 120 Hz and 30 Hz for 8K). Luckily the projector also seems to be HDMI 2.0 TMDS, so this shouldn't be an issue. I noticed there are two bytes left in the extension block for data blocks. If you plan to make any changes in the extension block, make sure there are at least two bytes left because NVIDIA's driver has a bug that will cause it to ignore the override if there are less than two bytes left. Also NVIDIA's driver currently has another bug with EDID overrides that can cause it to crash on boot sometimes if you have multiple displays connected, but it doesn't always happen so I'm not sure what the trigger is. I don't know if the dummy plug you have is writable, but if it is, you can write the EDID you want using this: https://www.monitortests.com/forum/Threa...yID-Writer |
