Yes you can power your 5K display directly with one of the DP1.4 ports of the Vega, if your monitor’s DisplayPort supports DP1.4, which I doubt.

However, you will be never able to drive a 5K monitor with the DP1.2 port of the Alpine Ridge as you originally stated above.

Dell User Manual said:
To display 5120 x 2880 at 60 Hz and 30 Hz, both DP1 and DP2 must be connected. DP source’s graphics card must be DP1.2 certified and Tile display feature, capable of supporting resolution up to 5120 x 2880 at 60Hz and its driver supports DisplayID v1.3.
Ill see the results Sunday and if it works ill have to drive 2000miles to get the second 5k monitor.

Also my Nitro+ RX Radeon Vega 64 8GB shows some coil whine, when squeezed during graphic intensive tasks, although so far only under Windows.
Hi @alineliodor, it is the same for me, I hear it every time when I use the interface of Final Cut Pro X or Blender in Mac OS X. I have the feeling it was not the case from the very beginning.

Cheers

I just bought TB3 to dual Display Port, shall have it on Sunday and will test if i can power the 5k Dell with 1DP via Alpine Ridge.
I have mine set to Disabled as well, as it breaks sleep.
I have such adapter, it works provided you connect both DP input on the thunderbolt card to two DP port out the GPU.
The Dell (like the LG ultrafine or HP z27q) can only work with two DP 1.2 SST. Thunderbolt 3 can carry two SST streams at once, hence why it works using a single TB3 port. But you can only have one of such screen per TB chipset.

So the end result is the same. May as well directly connect the two DP to the screen, than connect those two DP to the thunderbolt card, which then go to a TB3-> Dual DP adapter and then into your screen.

If you connect a single DP only, the screen will offer you two different resolutions : 2560x1440 or 4K (3840x2160)

BTW.. seems that the 2x LG 34WK95U-W 5K in TB daisy chain, LG was showing at respective events, were apparently running indeed with 4K only.
the 5K2K is now available on Amazon France for 1815€ ouch

Well here in Germany one would currently get it on Amazon MarketPlace for 1450€. But MarketPlace means, no full Amazon service and warranty. I had a chat with Amazon Germany yesterday, and they think that they would be able to directly offer the 5K2K here in Germany on Amazon within the next two weeks.

However, I was brainstorming your recent valuable statements and I am left with some big doubt if I really should go for the actual LG 5K2K at the moment.

Fact is, that there is not yet any 5K2K display on the market that features Titan Ridge technology.

The advantage of the LG 34WK95-U is that at least it features 5K2K and it also supports DP1.4. Important in my case, as I do have to connect both my X299 (TB3) and X99 (DP1.4) rigs to a single monitor. The big disadvantage is that it does not feature Titan Ridge technology. Thus it neither will be 100% compatible with the GC-Titan Ridge Add-In PCIe adapter nor support TB or TB 5K2K daisy chain. Nothing I would risk 1500€ for.

The only Titan Ridge Display on the market, seems to be the Lenovo ThinkVision P32u-10. But else it is just a simple 4K monitor with DP1.2 support. In my opinion, a simple waste of Titan Ridge technology.

I am unable to find any information on the upcoming Titan Ridge models of ASUS and Samsung presented at several events. But from the linked movie both do not seem to feature 5K2K either and there is no information on the DP ports implemented.

Thus probably it would be worth staying with my LG 38UC99-W for a couple of months more?

Changing from a 7980xe to a 7900x only requires to modify the provided TSCAdjustReset.kext in EFI/CLOVER/kext/Others ; right click on the file and select show content, then modify the Info.plist with the value 19 (10x2-1), it's all on the first page below the "C.) Important General Note/Advice and Error Prevention"
7.) d)

As for your slowness, I would blame your 980Ti ; if you want speed and video and 3d design on macOS, the 980Ti isn't the best choice due to the low quality of the nvidia drivers.
AMD is today the only GPU Apple supports natively
Thanks for the info.. I could not get the TSCAdjustReset.kext build at "C.) Important General Note/Advice and Error Prevention" to work. I ended up searching for a pre existing TSCAdjustReset.kext for a similar build. It works great! Now my question is what am i missing out on if i did not configure the TSCAdjustReset.kext myself.

Also there is no audio... any thoughts?
