LG UltraFine 5K Build

Hmm
Have you tried if your setup works at 5K resolution on Windows? Just to rule out any hw issues

It does work on 5k I think it's just a web driver issue, I returned the 1080 and I am going to shoot it out between the RX580 and the Vega and hope they update the Vega driver soon to support hardware acceleration outside of Metal. For now the RX 580 is working great.

So it seems at least 1 person got the LG 5k + nvidia to work:

I asked him for more details via Twitter..

He didn't post timing information from SwitchResX. He could be running 4K. If we don't see 900+ MHz, then the evidence is not conclusive.

I'll order one to try again. Vega in its current state isn't really stable anyway.

What issues are you having with Vega?
Isn’t it natively supported on High Sierra or is that just the RX series?

 

[Menno87]

Most Vega chips are supported. It doesn't matter if it's Frontier or RX. Same PCB, same chip and all the ids are in the AMD10000 controller (not sure for the Pro WX 9100) . The new drivers in 10.13.2 beta 1 are much better. (Closer to point release iMac Pro)

Have you tried running Electron based apps on 10.13.2 beta 1 to see if they still crash? Or running Chrome without disabling the GPU? If you run Slack or anything like that you can generally get it to crash the whole machine in a couple of clicks.

Yes that's the first thing I tried. Slack and some other electron apps. Even some OpenGL games that crashed. They don't crash anymore and utilization is 100% on my Liquid cooled frontier edition. So that's a good sign. This weekend I can do some more testing.
