How do i set the hdmi output of my j3455 to 3840x2160 60hz 4:2:0 ??

super mega thanks to those who unblock me from this situation because I tried for 2 hours with zero results:

You shouldn't need to change anything if both the monitor and GPU support 3840x2160 @ 60 Hz with YCbCr 4:2:0. YCbCr 4:2:0 resolutions are defined in the CTA-861 extension block in a 4:2:0 resolutions data block, which you can add by adding a TV resolutions data block and enabling the "4:2:0 resolutions" option. Windows will only list the resolution if the GPU driver supports it.

I will try, unfortunately the intel the hd500 like all intel graphics chips up to the new uhd700 series only supports 30hz on hdmi in 4k, I wanted to try to understand if by lowering the bandwidth it was possible to solve this problem since the graphics chip actually supports 4k 60hz on display port (which i don't have on my mb)

Some reported issues since 471.11, but that was a system freeze, not just a black screen. As for the TV, there's no way to add FreeSync to a display with NVIDIA. NVIDIA does not support HDMI FreeSync, only HDMI 2.1 VRR.

Thank you for your reply

Yes, changing literally anything causes a black screen, and if I remember correctly, a system freeze, forcing a manual restart.

I've tried 3 different drivers from January and February, same result.

Oh well, guess I'll try Scanline Sync or just use VSYNC on the HDMI TV then.

Hello everyone. I recently setup everything to stream from my gaming rig to my LG 4k TV which supports HDR. I got a Lindy 32014 edid Emulator ( https://www.lindy.de/HDMI-10-2G-EDID-Emu...pi=32104). The manufacturer says it supports emulating an HDR signal, but in fact you need another device to emulate HDR.

I tried messing around with CRU, adding a block with HDR information, trying various settings. But it had no effect.

Is it possible to to what I am trying and if yes, how can I achieve that?

Kind regards

Not that I know. Adding HDR data blocks with CRU doesn't seem to have any effect.

Thanks for your reply.

Do you know any other solution? I saw several programs for editing Edid data, but I never heard that this standard exists before, so I have absolutely no clue what's possible with that, if there is a pure software solution, or if further hardware to rewrite the edids eeprom is needed.

Modifying the EDID is not enough for Windows to allow HDR. There must be some sort of information in the video signal.

What do you mean by nothing seems to work? Describe what happens.

When i change the resolution to custom one, and press restart64 there is no custom resolution. i followed all the steps in the video i showed. also under extension blocks it says 2560x1440 @120hz instead of 2560x1440@165hz and detailed res is also 2560x1440 @144hz... when i have a 165hz monitor. all i want is to change the res to 2360x1440 @165hz. but it isn't working.

Is there a default extension block? Did you read the part about extension blocks in the first post?
