    5k Resolution with original iMac Panel and Nvidia Card

    Hey @joevt Thanks for your support and your patience, but I have decided to give up. Like I wrote in my last reply, the Display is way to dark compared to my MacBook Pro. Maybe the display is damaged or the Driver board. I don't know. Apart from that I think its to much effort and consumed to...

    5k Resolution with original iMac Panel and Nvidia Card

    Do you mean this? After a restart 45Hz is not valid. I can't apply it. But I was able to get 5K & 37Hz with the AMD Card and the HDMI cable. Sorry, I really didn't get this part. I never had anhing to do with the Terminal, this is completely new for me. I created a EDID file with SwitchResX...

    5k Resolution with original iMac Panel and Nvidia Card

    Thank you for helping me :) I think the custom resolutions with invalid settings (32768 pixels) come from SwitchResX. The Display definitely worked with one DP-Cable in nativ 5K on Windows. It never worked with two. I don't think the Controller Board supports MST. All the other Displays which...

    It´s the same panel Apples uses for their iMacs. It´s a LG LM270QQ1 Panel. I have a Thread here. https://www.tonymacx86.com/threads/5k-resolution-with-original-imac-panel-and-nvidia-card.282387/ I tried switchResX. nothing happened. Here is the EDID. I don't know what I should check in the EDID.

    5K Resolution (5120x2880) via NVIDIA Drivers on Dell UltraSharp 27" Monitor

    I do not have the Dell. My 5K Screen supports DP 1.4. That's why I´m looking for the Patch. It works perfekt on Windows but in macOS I have just 4K.

    I ordered a LG LM270QQ1 5K display panel, which is the replacement Display for 5K iMacs.
