Laptop + eGPU + external monitor (not picking up eGPU card)

Configuration: Akitio Node Titan + RTX 2060 S + Lenovo Extreme X1 Gen 1 + Dell u2518d monitor

Hey everybody,

I bought the node titan to use with my lenovo laptop some months ago and it's been working great. I recently got a monitor from my work, but now my issue is that the external monitor will not pick up the RTX 2060 S, but rather uses my laptops integrated GPU (GTX 1050 Ti Max-Q).

I currently have the laptop connect to the eGPU via thunderbolt 3 cable and then connecting my laptop to the monitor by a HDMI + USB B --> USB A. I am unable to connect the eGPU directly to the monitor as I dont have thunderbolt 3 connections on the monitor, but I do have a DP connection free. The eGPU has also a HDMI port (but I have no HDMI ports free on the monitor, it's being used to connect to the laptop). The eGPU does have a DP port, so perhaps connect the eGPU to monitor via DP??

The big question though is why is the monitor not picking up the RTX 2060 S card... I have specified certain programs to run on this card. Even more annoyingly, now my monitor 1 (laptop) is using the basic integrated GPU (not GTX 1050) and monitor 2 (Dell u2518d) is using the GTX 1050... There's no option to select the RTX 2060 S card either....

What do you recommend? I have attached photos of my connections.

Thanks I appreciate any help I can get here!

Edit: I'm not sure if it's possible to add pictures here, so I have put them into a google drive folder and provided the link: https://photos.app.goo.gl/2ui7VaLwPjhTyHdZA

Hi @seanhedman,

I can possibly give you some pointers with my limited knowledge (I am assuming you are using Windows 10). I'm sure there are others who know a lot better than I do.

A few things to check:

  • Have you installed the latest Thunderbolt driver?
  • Is your eGPU enclosure been recognised by the Device Manager?
  • Have you approved the Thunderbolt device (via the Thunderbolt Software - bottom right in the task panel)

As your set up, I would discourage the connection from your laptop to the monitor, and use the DP ports between the eGPU and your monitor, the reason is that (AFAIK) there will be even more performance degradation having the signal going back to your laptop. Also, if you have a high refresh rate monitor, DP port tends to give you the maximum refresh rate (depends on your monitor)

In brief, I would suggest the following:

  • Laptop to eGPU using the TB3 cable
  • eGPU to Monitor using DP to DP cable

These 2 recommendations may not help with your connection problems, however, check those points I have made (about the drivers, etc) and see if it helps.

 

Hope that helps a little.

Hey there,

Thanks for the help Smile

To answer your questions:

1. No I havent checked that I have the latest thunderbolt driver. I will do that.
2. The device is recognised in the Thunderbolt Devices Software

I will pick up a DP to DP cable from my local electronic store tomorrow. I'll let you know how it all goes. 

In short, I have found a workaround. Basically I use a software called Houdini to make VFX (for work purposes) and I have the computer set up to use the RTX card when running this software. So that's all good, but would be nice to have it just run by default on this monitor. 

Thanks again, and I'll keep you posted. Have a nice weekend!

Sean

Hello again,

I finally got a DP to DP delivered and connected it, disconnected the HDMI from laptop to monitor and now it all works great. Monitor using the eGPU card Smile

Thanks ever so much for your help and have a nice day!

Cheers,
