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...
I tested the others too. But im only able to have two valid custom Resolutions in the free Version. The other resolutions between 30 & 60 Hz. are all not valid and I can't apply them.
Yes. 31 -36 also works.
I can create them, but there not valid and I can't apply them.
I found another...
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...
I was at the store after work and bought a Asus Radeon 570 with 4GB.
But I can't get 5k 60Hz with that card too :problem:
The limit is still 30Hz. If I choose anything higher, a don't have a Picture. Thanks for the advice with screen Sharing!
Yes I tried HDMI 2.0 too. only 30Hz. With both...
Good Idea, I will do that.
And I will try all Hz settings between 30 ans 60Hz. might take a while.
I´m at work now, Will do it today evening.
I asked myself that too.
If I try something else then 1.4, nothing changed. But 1.3 doesn't work. I don't have a Picture.
It selects the one that...
I tried several Custom Resolution settings. 31hz, 46hz. It doesn't work. When I apply the new create setting after a restart my screen turns black. It took me some time to get the Picture back.
I attached a zip, which contains a Video to show you the Panel Settings.
I changed the...
Now I have 5K with 30hz :D
But now, I don't know why, I don't have a boot screen anymore. I don't see the Gigabyte logo, I don't see clover.
Only when macOS is booted I have a picture.
Before I added the 5k 30hz custom resolution I was able to see The Gigabyte logo an clover with...
After 3 hours I did everything you wrote (I Think).
I am very very thankful that you are trying to help me. I hope you can understand me, I´m not a native speaker.
And I hope everything I did today was right and was a little step in the right direction.
Yesterday I installed High...
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.
I tried switchResX. nothing happened. Here is the EDID. I don't know what I should check in the EDID.
I ordered a LG LM270QQ1 5K display panel, which is the replacement Display for 5K iMacs.
With this driver Board I can use it as a normal Monitor. https://de.aliexpress.com/item/33014928363.html?spm=a2g0s.9042322.214.171.124ae74c4dciTjsY
So I can build a 5K display in a real iMac Case. In windows, its...
I found a guy who did exactly what I wanted to do.
With this driver board you can use an iMac 5k Display with any PC.
So i ordered an iMac Case, a Replacement 5K Display and the driver board.
Now I have to...
I already have a Cinema Display, but I don't use it anymore because of the resolution.
Any idea where I can find a controller/Adapter for the 5K iMac or the Display specifications to find out which one I need?
Is there any way to use a broken 5K iMac as a Display? I know Apple removed the function to use target display Mode, but I thought maybe there is a way to open the iMac, remove all the PC parts and use an adapter to connect the Display with a computer.
When people fit a Hackintosh in the old...
@domkikong in the framed Area are small metal pieces. I´m not sure how to call them in english. You have to remove them. I used a screwdriver. Unfortunately I have no picture or video. I can't explain it very good in English. sorry
@bixmix Thank you :)
I didn't´use the original apple...
