@le_quang_duc, what model MacBook and Ultra 4K are you talking about?

The Huawei vr 2 cable works only in one direction - from computer to display. Power comes from the computer via USB 2.0 port (only a few watts) and goes to the display.

 

Mac mini (2018), Mac Pro (Early 2008), MacBook Pro (Retina, 15-inch, Mid 2015), GA-Z170X-Gaming 7, Sapphire Pulse Radeon RX 580 8GB GDDR5, Sonnet Echo Express III-D, Trebleet Thunderbolt 3 to NVMe M.2 case

Any in-stock alternatives to the Huawei VR 2 cable?

Don't have an eGPU but stumbled upon this thread when looking for a solution to connect an original 21.5" 4K UltraFine to a PC. The cable isn't available anymore and costs upwards of $100 on eBay. If there's no alternative, I'd consider the eBay option but is there confirmation that it drives the full 4096x2304 at 60 Hz?

4096x2304 at 60 Hz is DisplayPort 1.2 so any of the listed options should work.

@joevt, Thanks! I purchased a bidirectional ALOGIC USB-C to DisplayPort cable and was able to connect the LG UltraFine 4K (older 21.5" model) to an RTX 480 on a gaming PC and it worked! 60Hz at 4096x2304. No USB or audio but this will do for now.

@instrumedley, interesting as most other posts suggest that this display needs USB power as well.

Thanks for keeping us posted!
