Hi ToastyX, I don't think this is a cru problem but maybe here can help me out, this is my problem..

I can create a 4k exact resolution using CRU, with let's say we 300 lines of back porch.. when gaming using RTSS, when the sync value is 0 the tearline might or not show up on screen (this is ok), at 1 it shows at the 1/10th of the screen (more or less which is ok), the problem starts here, if you start moving the tearline down you can see the sync value changing but the tearline wont move until you get to 210 (300-90), after 210 you will see the line moving down, the last visible line for the tearline is always 90 lines before the total vertical and the tearline will stay up at the top of the screen while the sync value is lower than the vertical blanking. resuming, no matter the vertical blanking I use (tried with up to 2500VT using CRU) I only have 90 lines below the active image.

Hi, I was wondering if CRU could change Miracast connected wireless display resolution or not? I've already tried but had no luck, as miracast driver settings does not show my custom added 1600x2560 resolution via CRU.

To be more specific: I'm extending my laptops display with Samsung Galaxy Tab S6 tablet, which has 1600x2560 native resolution, but somehow I cant use it, as display setting max is 1440x2560, thus I have huge black lines on top and bottom of my tablet while using it as wireless display.

This is what doesn't make sense. This is impossible because it can only be using what you loaded.

That's because you still have the resolutions in the EDID.

Both of your edits still have 1080i and 720p defined as TV resolutions. Windows might not list 480i and 576i, but they should be available for programs to use if the driver supports interlaced resolutions.

Yes, but CRU doesn't have a way to do that. Here is a basic analog EDID with 480i and 576i:

You should be able to load that into the NVIDIA control panel as is. You can also import it with CRU to edit the resolutions.

I see, thank you very much, I'll try your EDID right away. I hope windows will list it, I'd like to be able to normally use the PC on the SD-CRT Tv but perhaps they removed this possibility.

I copy/pasted your values into a TXT file (390 bytes) and loaded it on Nvidia CP. It loaded succesfully on the DVI-I port.

Windows set it as inactive by default (I get "show only on 1" option), I cannot extend the monitors. Tomorrow I'll connect the UMSA and try "show only on 2" option. I'll make you know if it'll work.

Try changing the vertical front porch instead. You will have to use a DisplayID extension block.

If Miracast mirrors the laptop display, then you'll have to add the resolution to the laptop display, but laptop screens normally don't support non-native resolutions, and if the laptop has an Intel GPU, the driver might not allow custom resolutions at all on the laptop screen.

Looks like The monitor which I have been purchased recent day has HDR10+ facility, is this the world's first monitor to support that facility?
anyway my question is how do I edit that edid with cru tool, as you can see it completely greyed out! is there any other way where I can view what information inside on it with 6 bytes data?

Optional request:
Do you have newer version of advantiv-edidgold? looks like they takendown their download link for harsh matter Undecided

It's not the first display I've seen with that data block, which is why CRU recognizes what it is. Gray just means CRU can't edit it, but it's not disabled. The HDR10+ data block is a vendor-specific data block, so I don't have any information on how to decode it. There doesn't seem to be anything useful to edit anyway. The first 5 bytes are basically the header which indicates it's an HDR10+ data block, so that only leaves 1 byte of actual data, which is probably just a version number.

Thanks for reply. I am extending my laptops desktop not mirroring, Intel GPU right. But maximum resolution I can get from display settings is 1440x2560. May CRU somehow help in this case?

Many thanks for clarification about it, now it is littlebit clear . but should there be another block call "HDR dynamic Metadata" ?

I will have no problem with that version, I just need that tool.

I've already tried that and it's a complete weird situation, my drivers will detect the vertical total but RTSS will say VT the sum of back poch+sync+active, the front porch is not taken into count.

I have even reinstalled windows and is the same.
