MP 1,1-5,1 testing TB3 AIC with MP 5,1

[Montyboy]

Which UltraFine display is it - the 4K (USB-C) or the 5K (Thunderbolt 3)?

I have the 27 Ultra Fine 5k Thunderbolt 3 Display.
When i double click on current resolution in SwitchResX...... Nothing happens.




The LG 43UD79-B appears to be a 4K display with HDMI, DisplayPort 1.2, and USB-C display inputs. The 5K resolution refers to the frame buffer size (5K). The frame buffer size is scaled down to the screen resolution size (4K). You need to double click the current resolution in SwitchResX to see the screen resolution (active pixels, pixel clock, horizontal and vertical scan rates).

USB input is done through the USB-C input? You did not test the USB ports? The manual says the USB ports are SuperSpeed (USB 3.0). They don't mention that only HighSpeed (USB 2.0) is possible using USB-C with DisplayPort 1.2 alt mode at 4K 60Hz. Maybe USB 2.0 is used when the display input is set to USB-C, and USB 3.0 is used when the display input is set to DisplayPort? To use USB 2.0, you'll need to connect USB ports to the USB 2.0 9-pin connector on the GC-TITAN RIDGE. USB 3.x should work without USB 2.0 connection.

Audio works with this display because it uses DisplayPort audio instead of USB audio. USB audio would require a working USB controller and connection.

The LG 43UD79-B is not a Thunderbolt display, so it won't show any extra PCI devices. But you see the info for the Titan Ridge USB controller (pci8086,15ec) and NHI (pci8086,15eb) when you use the jumper wire or when you boot with a USB device connected.


You will need Windows to see or use the PCIe devices in the LG UltraFine 5K display (the USB controller inside the LG UltraFine 5K controls audio, camera, USB ports, brightness control).[/QUOTE]

SwitchResX 7.2 seems to have some bugs in Mojave. Go to the SwitchResX download page and click the download picture to get 4.8.0. After you install it, in the list of "Current Resolutions" you should be able to see which resolution is selected as the current resolution. Double-click the current resolution to see its timing information.

Using 8K resolution or 4K HiDPI mode on a 4K screen is redundant, unless you're testing 8K performance.
[doublepost=1541241317][/doublepost]Your screen shot shows both the LG UltraFine 5K and the LG 43UD79-B working together. But to get 5K resolution, only the 5K can be connected to the GC-TITAN RIDGE. Are you connecting the LG 43UD79-B directly to the graphics card instead of the GC-TITAN RIDGE?

If you are connecting both to the GC-TITAN RIDGE, then the LG UltraFine 5K is probably outputting only 4K. SwitchResX will tell you the output timing. Maybe if you connect the LG 43UD79-B first, then the LG UltraFine 5K will only get 4K when you connect it second? If you connect the LG UltraFine 5K first, then maybe the LG 43UD79-B won't work when you connect it second?

You young whipper snappers and your fancy 5k displays, back in my day we had 320x240 6" monochrome displays. If you looked are the too long, your eyes would bleed.

That's the way it was and we liked it.

Thanks for your help and advice...
As i was testing both displays were connected to the thunderbolt ports of the GC-TITAN RIDGE. LG UltraFine with Thunderbolt cable and LG 43UD79_B with USB-C/USB-C cable.
I cannot find SwitchResX 4.8.0 anywhere

Thanks for the zip file....
I have taken a few screen shots, I don't know if this is what you meant...
The first 3 shots are from LG 43UD79-B 4k resolution.
The last 3 shots are from LG UltraFine 5k resolution.
Only one display was connected during the test.
I think I will have to install Windows...... Once again thanks for your help.

Double-click the current resolution (the one with the hilited radio button) in the "Current Resolutions" list. You'll see that most or all of the resolutions that are marked as "Scaled" will use the timing the matches the "Scaled Resolution Base" which is 3840x2160 for the LG LG 43UD79-B display. Post one or two examples of a scaled resolution for each display (such as the 5K and 8K scaled resolutions for the 4K display.

Screen Shots from LG UltraFine Display @5k resolution.
Hope i got it right this time..
I will install Windows when i have more time....Thanks

Those screenshots appear as expected for a 5K 60 Hz display. There is no indication that the display uses two DisplayPorts - I guess that detail is hidden by graphics drivers.

Those screen shots have the same information. Did you mean to include a different screenshot? Maybe include a screen shot of a scaled resolution to show how it uses the 5K timing to display the frame buffer (the frame buffer, which may be smaller or larger than 5K, is scaled to 5K for output to the display).

Windows is only needed to enable the camera and audio and USB ports and brightness control of the display because they use Thunderbolt for communication between the computer and the display's USB controller.

@Montyboy, are you able to get the 5k Ultrafine to display an image on cold boot without power cycling it?

I have to power cycle to make it work.
I will do more tests later and post results..

Did some more testing today but ran into problems.
Each time i changed resolution with SwitchResX I got just black screen, I would then have to restart my mac and also pull the plug from the Display. When the display appeared it would be in the resolution that I had changed it to, then I would change resolution again only to get a black screen. I did this a few times but then lost connection with bluetooth keyboard ( I don't know if it had anything to do with changing resolutions ) I am now using my LG 43UD79-B managed to get my keyboard working again... Here are a few screen shots from the UltraFine display I have named each screen shot to the resolution i was using at the time of the shot....... Hope it helps. The last screenshot I had to use a magnifying glass ;-))

Having to power cycle is a strange but apparently common problem with the LG UltraFine 5K. Are these tests with Thunderbolt PCIe communication enabled (you ran Windows first?) or without Thunderbolt PCIe communication (no camera, audio, USB ports)?

You misspelled HiDPI. The 1280x720 screenshot should be labeled 1280x720_HiDPI.png. The rest appear as expected.

I do not have Windows yet.
Without Thunderbolt PCIe communication.
Is it normal for the display to go black when changing resolutions and forcing a reboot?

I'm not sure. I think it's possible that if the display doesn't have a PCIe connection then it thinks it should go to sleep.

Okay so I got around to testing with both Displayport pass throughs connected and still no dice in either windows or Mojave.

It also wouldn't connect to a 2016 MBP in target disk mode.

Factionrider, were you able to get the Apple Thunderbolt Display to work? I have one that I would like to use with my 2010 Mac Pro. I received the Titan Ridge card yesterday.

 

[Factionrider]

Nope. No dice so far. I’m sure it can be made to work if the right person comes along and forces the system to load the titan ridge kext from the 2018 MBPs.

 

[misanthrophy]

I've mostly read the posts on this thread, but now I have some questions:

Is this card "fully supported" on 10.13.6?
What exactly do I need to get it working?
Has anyone already tried, if you can connect the new iPad Pro directly with the card and does it charge/be visible for Duet Display?
Does it make any difference (regarding speed/compatibility) which of the 4 slots I am using? (BootROM 140.0.0.0.0 is running)

Thx in advance!

Not at all supported in 10.13.

I would expect an iPad Pro to show up properly, every other usb c device I’ve tried has. Charging theoretically should work if you have the power cables available inside the case. It takes 2 6 pins for 100w on one port and 60w(?) on the other.

Slot chosen shouldn’t matter, but again, none of this works at all in high Sierra.

So Mojave is needed?

I don't think Mojave is needed.

I just ordered the necessary parts to do the Pixlas Mod on my mac pro so i can power this card. So far I haven't been able to detect all of my USB devices. So far, using a usb-c to usb B cable i was able to connect a external HDD through a usb 3.0 hub but nothing else.

this is the cable I use:
https://www.amazon.com/gp/product/B00UUCJRFW/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
this is the hub I use:
https://www.amazon.com/Anker-9-Port...274&sr=1-5&keywords=anker+10+port+usb+3.0+hub

Weird thing is only port number one on the hub works, and not all devices. for example my apple wired keyboard does not work. The external HDD is working at full usb 3.0 speeds, no header connected.

Update: Seems like all ports of the usb hub work. but only with External USB 3.0 Devices.

USB 2.0 requires connecting the USB2.0 9 pin header of the GC-TITAN RIDGE. You need a USB 2.0 port for each Thunderbolt port. You can use a couple of 5 pin connectors (make sure you have them connected the right way). Maybe consider an internal USB 2.0 hub like the NZXT or hubby7. I haven't tried them. I think you will want a 5 pin to connect to a USB port of your computer, then you'll want a single hub to be able to power the two ports of the 9 pin of the GC-TITAN RIDGE. Without a hub you will need two free ports on your computer.

 

[joevt]

Those results all look as expected, except there might be a bug in the pcitree.sh script in the part that tries to interpret the max and current link width and speed, because I don't see stuff like x16 for the graphics card, etc. Maybe you can track down the problem, or send me the temporary files created by the script in a private message.

Actually, a bug was introduced into setpci which caused it to be unable to find capabilities. I was using an older version that doesn't have the problem. You can fix the broken function and execute "sudo make install" to rebuild it.

 

[devel0per]

I don't think Mojave is needed.

You're right, joevt. The card also works in High Sierra.

I have a 2010 Mac Pro with the GC-Titan Ridge AIC, Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 adapter, and an Apple Thunderbolt Ethernet adapter working on High Sierra (10.13.6). I needed to jumper pins 3 & 5 on THB_C header cable, boot into Windows 10 with the AIC driver installed, and then reboot into macOS High Sierra for it to work.

Thank you for the update, Factionrider. I wonder if we need to connect the USB 2.0 header cable on the AIC to make the Apple Thunderbolt Display work.
