Is the U3415W USB upstream cable connected from the U3415W to a USB port on the laptop?

U3415W User's Guide

HDMI cable from my monitor is going to the HDMI in my laptop. And also I m very sorry but I don't know what is upstream cable ? 

I just ordered Type C USB to HDMI converter, hoping that would solve the problem in case you don't manage to find the issue :(...

Also when I did a DDM test, I remember some of the messages were related to :

"Error: communicating via DDC/CI" and also something that my monitor is not supported or similar...

Thanks a lot man and please help me out on this..

To add to my previous post, here is my DDM diagnostic report:

The fault is not the monitor. You should post the issue on the Laptop Video board and ask the Laptop users what they think about the issue.

Hi sir,

Yes, I have tried this last night and no luck. Monitor does work on my desktop machine but it makes no difference to me since I need this screen for my laptop. 

Laptop does recognize the screen under device manager only on HDMI (HDMI2) but when I try any other option such is DP, it doesn't even recognize it nor show it anywhere.

My laptop also recognizes the screen in my display menu and I can set the resolution to it etc but screen is simply in sleep mode all the time, nothing shows up.

Do you think that C type adapter to HDMI will solve this issue when it arrives ? What else can we do to fix this ? 

Open the link I provided in my previous post. Go to page 32. Read, "Connecting the USB 3.0 cable". Go to page 6 and see "USB 3.0 Upstream cable". Go to page 10 and you will see that the cable plugs into port 8-1. The other end of the cable plugs into the laptop USB port.

Page 13 of the manual =

I do not know. Ask the users on the laptop board.

Is HDMI 2.0 required for this monitor to work ? Also, will it be possible to ouput the signal using C type thunderbolt (thunderbolt 3) to HDMI ? Thanks in advance

I'm afraid that is an Intel HD Graphics 530 display driver error - it can only be fixed by Intel.

Sadly I had to spend 122$ extra and order: www.startech.com/.../thunderbolt-3-to-dual-displayport~TB32DP2

I have Thunderbolt 3 port on my laptop so hoping this will solve the problem, honestly, still have no clue, I bought this on risk so we'll see. It makes me really sad knowing that my laptop is one of the top series with 10/10 performance score and yet this thing didn't work instantly. I can see that some companies just can't get along and build unified and good solution in both terms, hardware and software.
