Reddit mentions of StarTech.com Thunderbolt 3 to Dual DisplayPort Adapter - 4K 60Hz - Windows Only Compatible - Monitor Adapter - DP Adapter (TB32DP2)

You have a couple of options to drive dual 4K monitors.

1. A Thunderbolt 3 Dock like the Dell TB16
   
2. One of these dongles: Plugable or Startech
   
   I've used all three on my 9550 and they all produce dual 4K at 60Hz. As others have said, the HDMI is version 1.4, meaning that it can produce 4K but only at 30Hz.

Yes, it works.

I have also used this successfully with my X1c 5th gen: https://www.amazon.com/gp/product/B01ANR4CYE/

I'm considering the same setup and I've done some research into adapters. Thunderbolt 3 docks are really expensive, especially the ones with 2 display ports + others. My plan so far is to buy a dual display adapter for the thunderbolt 3 port and a 4 port usb hub for the usb A port for keyboard mouse, + external storage.

Best deal I can find on external dual display adapter:

Your laptop supports HDMI 2.0 but I don't know if 2.0 can push enough bandwidth for 1440p @ 144Hz.

However, your laptop's USB-C port is actually a Thunderbolt 3 port! So you can definitely make some headway there, although you'll need a Thunderbolt 3/DisplayPort adapter like this one.

For the cost of $16.99 (USB C to DisplayPort Cable) I am willing to try it... Certainly cheaper than TB3 to 2 x HDMI adapter, which is +$100: https://www.amazon.ca/StarTech-com-Thunderbolt-Dual-DisplayPort-Adapter/dp/B01ANR4CYE

These adapters are supposed to be able to support dual 4k:

https://www.amazon.com/Plugable-Thunderbolt-DisplayPort-Supports-4096x2160/dp/B01F81EIBC/
Also, StarTech has a dock coming out in a couple of months but otherwise have not seen any docks that support dual 4k.
https://www.amazon.com/dp/B01AAAU4WS

Defenitely! Use one of those options:

• 1. A Thunderbolt 3 Dock like the Dell TB16
     
• 2. One of these dongles: Plugable or Startech

Hello,

Yes it's for a development environment. I think that startechs adaptors might do the trick, I found this one on Amazon that has a few User Q&A's claiming plug and play support on Ubuntu.

Thanks dude!

Did some more research... this article notes that the recent MacBook Pros support MST https://support.apple.com/en-ca/HT206587
So with that info, it leads me to believe that this adapter would work: StarTech.com Thunderbolt 3 to Dual Monitor DisplayPort Adapter - Thunderbolt to 2x DP Converter - 4K 60Hz - Windows only Compatible https://www.amazon.com/dp/B01ANR4CYE/ref=cm_sw_r_cp_api_9.OxybJ7FBNSD
I am pretty sure where it says incompatible with Mac, means incompatible with the older macs that only support SST. Anybody know for sure?

https://www.amazon.com/StarTech-com-Thunderbolt-Monitor-DisplayPort-Adapter/dp/B01ANR4CYE

Now that I look at it, its USB-C to Dual DisplayPort, and it looks like it might cap out at 60hz? Would need this verified, though.

first of all, very important, not sure this will work, never tried to get 2 5k monitors out of 1pc

this should get 5k out of the monitors, for only 4k there are simple ways!

you will also have to buy 2 of these, plug 1 to each monitor and the DisplayPort cables from the GPUs to them

if the red footage is 8k consider double the ram

this pc should meet the minimum requirements for this to work. nevertheless, ask for other people opinion/advice because like i said earlier, i'm not sure this will work

EDIT: changed words

I had the same issue on my xps 13 when using this thunderbolt adapter:

https://www.amazon.ca/StarTech-com-Thunderbolt-Dual-DisplayPort-Adapter/dp/B01ANR4CYE/ref=sr_1_1?ie=UTF8&qid=1495739645&sr=8-1&keywords=startech+thunderbolt+3+display+port

but not when using this one for some reason:

https://www.amazon.ca/StarTech-com-USB-Multiport-Adapter-Ethernet/dp/B01EKARUUS/ref=sr_1_11?ie=UTF8&qid=1495739704&sr=8-11&keywords=startech+usb+c+hdmi

Though, since I wanted to use a double screen I investigated. Thought I had fixed it by doing a thunderbolt firmware update. Which I did the week I moved to a new apartment. Everything was fine for a month, but I had to move back to my previous apartment. The problem started to reappear. So it was environmental, not a software issue. I figure it must be something with the power or interference. It was apparently the later.
Here is my fix:

Yup.... ugly, but it works!

You can buy a usbc to displayport/minidisplayport adapter, then connect a mst hub to connect 2 or 3 monitors all at once either directly to two port adapter, or buy an additional mst hub.
e.g. https://www.amazon.com/gp/aw/d/B0746NKVBN/ref=mp_s_a_1_4?ie=UTF8&qid=1523723617&sr=8-4&pi=AC_SX236_SY340_FMwebp_QL65&keywords=usb+c+alternate+mode&dpPl=1&dpID=310B5ayd2oL&ref=plSrch

or
https://www.amazon.com/StarTech-com-TB32DP2-Thunderbolt-DisplayPort-Adapter/dp/B01ANR4CYE


or get these displaylink solution
e.g. https://www.amazon.com/Plugable-DisplayPort-3840x2160-Thunderbolt-Compatible/dp/B074743NHP

or two hdmi version

Do you think something like this would work? Thanks

LOL they dont even know how to set to default a synapse profile for my keyboard, i dont know how they could answer my questions about PCIe lanes and specific thunderbolt 3 questions.

I could give it a try, but no big hopes.

i understand that the blade uses the latest tb3 version, but if you take a look at these 2 links here, and you scroll down a bit, it mentions that razer blade stealth only supports single display output via tb3

Found that one on Amazon, but I'm not sure if it would work.
