I just tried an Asus 2080 TI in my Mac Pro 5,1 with Windows 10, it's a no go with the Apple Studio Display and the Thunderbolt 3 cable that came with the ASD to the USB-C port of the card. Expected.

I then additionally installed the original 5770 card and a DVI cable to an old monitor and I got picture to the old display, still black picture of the ASD. I switched to an unspeced USB-C to USB-C cable (from a USB 3.1 charger) and Windows identified the ASD as a USB-hub. Weird. It asked me to reboot so I did.

Upon rebooting the screen was still black on the ASD but in the display properties it showed up (as monitor 2) but with max res of 2560-ish. Still couldn't get picture. Sound worked fine though.

I wonder if it would work properly with a 40gbps USB-C to USB-C cable or if I must get a Belkin VR cable.

A lot of Thunderbolt 3 cables, particular Apple cables, don’t pass DP Alt Mode video. Most USB-C power cables don’t pass any data except the USB 2.0 data lines. If you have a USB-C port on your GPU, you should be good with just a good quality USB-C cable that is specified to pass video. I usually go with Cable Matters but lots of vendors. The Belkin cable is probably not necessary in your case.

Yeah I thought so as well, I'll try a good USB-C cable first, I'll check Amazon, appreciate it.

This is the exact GPU I have:


3 x DP, 1 x HDMI, 1 x USB-C.
 
After many many unsuccessful trials with all kind of cables I am looking to the option to buy the Belkin Sync & Charge cable. Unfortunately I cannot justify the $80-100 price for use with an old W10 laptop on the way to retire.

But if I could use it with other devices it could be worth the price.

Could a Belkin cable owner test an Apple TV with the Studio Display? Particularly if the sound is working.
Thanks

That won't work.

Yeah, I think the cable is your problem. That USB-C port should be exactly right for driving this monitor. That said, might want to check out this entry in the Asus FAQ if it doesn’t.

What do you guys think of this cable?


Think it would work with my 2080 TI which has USB-C? The port on the GPU is working fine, I've connected USB-C to DP to an old monitor and it's fine.
According to that URL, it won't work for what you're trying to do. Halfway down the page it says it doesn't support Displayport. If you're going with a Thunderbolt cable, you need something like this one that is Thunderbolt 4 and specifies that it supports DisplayPort Alt Mode.

It really is a jungle isn't it? So this should work then?


Sorry, it's in Swedish.

Alternatively this. I don't need a long cable. Want to retain speaker functionality though.

First one should work, second one claims it will work since it mentions DP Alt Mode.

Thunderbolt 3 cables won't work for USB-C non Thunderbolt ports. You need expensive Thunderbolt 4 cable or less expensive USB-C 10 Gbps cable.

Thanks for the help everyone, I ordered the Cable Matters cable in my post above, I'll update here on the compatibility when I receive it.

The Mac Pro 5,1 is just a secondary computer for Windows compatibility and for the occational game or application, I'm aware the 2080 TI is not working in Mac OS.

I normally use a Mac Mini M1 with the ASD, works great.
 
I DID IT

I INSTALLED A REAL BRIGHTNESS CONTROLLER!

I can also switch reference presets

Guide:
  1. Download brigader.exe from: https://github.com/timsutton/brigadier/releases/tag/0.2.4
  2. install python 2.7 from https://www.python.org/downloads/release/python-2718/
  3. open CMD in admin
  4. making sure to replace [pathto] to your downloaded file, type c:\python27\python [pathto]\brigadier.exe --model MacPro7,1
  5. This will download the bootcamp drivers to your user folder C:\Users\[nameofwindowsuser]\bootcamp(something something version)
  6. Delete the extra drivers you don't want to install, namely all non-apple related drivers.
    in $WinPEDriver$ only have:
    1650027164230.png

  7. and then in \BootCamp-002-34411\BootCamp\Drivers
    keep only Apple and Promise folders
  8. run in cmd (admin) msiexec /i C:\Users\[nameofwindowsuser]\BootCamp- whatever version \BootCamp\Drivers\Apple\BootCamp.msi
  9. install, then restart
  10. be noted this will rename your C drive to bootcamp, i'm pretty sure you have to keep it that way otherwise the bootcamp control panel will not open

@kreasu_ @Amethyst1 @joevt Here are some testing results on Windows 11 with my new Apple Studio Display (iOS 15.4) that you might be interested in.

Things that work using a 2m Cable Matters TB4 cable:
  • My Framework laptop at 5K resolution, Iris Xe graphics
  • Speakers on the Studio Display
  • D-Link 2.5Gbps Ethernet adapter plugged into the Studio Display - at the full 2.5Gbps
  • Microsoft Surface Go 2, at 3840x2160
  • Logi 4K Pro Magnetic webcam (usually for the XDR) connected with a J5Create JUCX01 USB-C cable (need to ensure you're using a USB-C cable with enough bandwidth here)
Doesn't work:
  • Using the included Apple cable. The Framework just spazzes out like it's trying to connect/recognize, but never does.
  • Brightness? Seems like it keeps/locks the same brightness you set via a Mac? I checked in the Intel UHD Control Panel app, and didn't see any means to adjust the brightness. Guidance is appreciated.
  • (This works on my Pro Display XDR :confused: ) TB3 output via my ASRock X570 Phantom Gaming-ITX/TB3 motherboard using its Ryzen 3 5300G. This PC previously works at 4K my Pro Display XDR, as well as 4K on my 4K LG monitor, using a USB-C connection via its TB3 port. When connected to the Studio Display, the screen flashes in a major seizure way, but I was able to squint and the PC recognized 3840x2160. Lowering the resolution on the PC didn't help with the flicker, and I tried with all sorts of cables.
I do have Nvidia and AMD GPUs that support DSC, and the Belkin Huawei VR cable, but I won't use/build a PC with all that kit for a few more months. I'm bummed that my AMD PC won't work, but at least the Framework and Surface seem to be fine.

Great work!

Am I correct in assuming that without your steps above, the ASD just 'remembers' the last brightness setting you applied in macOS, and just keeps it there when connected to Windows?

it does! if you're on the latest firmware, if you're on 15.3 it will go to max brightness every windows boot up.

OK that is awesome. Because the Brightness setting I've set in macOS seems to translate very well into Windows.
 
I have read the entire thread, but I am not sure what my next step should be, or if I should even expect to be able to get 5K@60Hz on the Studio Display from an HP EliteBook x360 1030 G4.

It has an i5-8365U with UHD 620 graphics and two Thunderbolt 3 ports:


It looks like max resolution of the UHD 620 is 4096x2304@60Hz:


I can run the Studio Display and an HP Z27 at the same time at 3840x2160@60Hz using two of these:


(Audio, microphone and webcam all work, although the camera quality is atrocious.)

I briefly got Windows to show 5K in the resolution list, I believe using one of my TB3 cables that came either with a TB3 HD enclosure, the Caldigit TS3+ or the Plugable TB3 dock, but choosing it would only revert back to the previous resolution, and now I can't get the display to show anything at all with any of the other cables.

Is it possible to drive (only) the Studio Display at 5K from the EliteBook x360? If so, any suggestions what I should try next?

Regrettably I do not have admin rights, so I am a bit limited in what I can do.

As long as you're not planning to game on it you can use a displaylink adapter to get 5k output. https://www.synaptics.com/products/displaylink-graphics/displaylink-products-list

And then to get usb c alt back, you use a Moshi Cable to the ASD

You should install the BootCamp driver #114 but maybe you can't do that without admin rights... In that case, install Windows to a different hard drive or partition to get admin rights.

Find out how many displays you can connect to the Thunderbolt port using a Thunderbolt hub or dock or Dual DisplayPort adapter. (not MST hub). In order for it to be able to do 5K60, the Thunderbolt port needs to be able to connect two displays without using an MST hub.

Ignore ark. I think the max resolution of the UHD 620 can be 5120x2880 if you can create a custom timing with lower refresh rate. For example my CPU (Core-i7 6700K with HD Graphics 530) can do 5120x2880 43Hz. #53
https://ark.intel.com/content/www/u...76700k-processor-8m-cache-up-to-4-20-ghz.html
For this connection type, I would try a USB-C cable instead of Thunderbolt cable to force a single DisplayPort connection. It might connect as Thunderbolt 20Gbps (with support for USB 10 Gbps). Or use a Belkin Charge and Sync Cable to force a DisplayPort only connection with USB 2.0.

Collect the list of EDIDs you can get with the different connection methods (reset-all.exe between each test).

The Studio Display only accepts HBR2 link rate with or without DSC. DSC or dual HBR2 is required for 5K60.

To support 5K, the DisplayLink adapter could take a 5K USB input and output two 2560x2880 HBR2 signals. I don't think any DisplayLink adapters support HBR3 or DSC output. I don't think there are any MST hubs that can do compression (to convert HBR3 to HBR2+DSC).

Synaptics has MST hubs that have a feature called ViewXpand that can make the MST hub with two displays connected behave as an SST display but I don't know how to force enabling it or if it can support two 2560x2880 displays (which is what the LG UltraFine 5K or Studio Display actually are when not using DSC). There's no documentation regarding the feature. As far as I can tell, it's only usable when connected to a computer that doesn't support MST? Which means DisplayPort 1.1 HBR link rate.

But in any case, you need a Thunderbolt 3/4 Add-In card to convert the two DisplayPort signals to Thunderbolt because 5K60 requires both DisplayPort connections.
 
You should install the BootCamp driver #114 but maybe you can't do that without admin rights... In that case, install Windows to a different hard drive or partition to get admin rights.

I am fairly confident that this laptop is locked down hard enough that I cannot install drivers or boot from a different drive.

If I connect the CalDigit TS3+ to one of the Thunderbolt ports on the EliteBook and the Studio Display to the other Thunderbolt port of the dock and the Z27 to the DP port of the dock I can still run both at 4K@60Hz.

Then you should be able to connect duel link SST 5K displays like the Apple Studio Display and LG UltraFine 5K and Dell UP2715K and HP Z27q to the Thunderbolt port. If it doesn't work immediately, then Intel needs to adjust their drivers, or Apple is doing something weird.

Maybe post questions at https://community.intel.com
They'll probably tell you to talk to Apple.
Then you'll tell them to check their driver to make sure it can work with the Apple Studio Display EDIDs where:
1) the left tile has: base block, CTA extension block with tile timing, Display ID extension block with tile info, Display ID extension block with single tile mode requiring DSC (unless 6bpc is a possibility which for some reason is not for Intel drivers??? Why??).
2) the right tile has: base block with no timings, CTA extension block with tile timing, Display ID extension block with tile info.
And ask how you can verify that the Intel driver is reading the EDIDs correctly.
