Surface Dock 2 Display Problem

Dear Swiss Julian,

Could you tell me if the adapter you bought is model HFP-00003 ?

Also, do you have the right screen frequency (max compared to your screen) with this adapter ?

Thank you in advance for your feedback.

Best regards

Hello everyone !

I also have the same problem with a 34 '' Samsung S34J55X screen and the new surface dock 2.

I updated the dock2 drivers but it doesn't change anything.

My screen works well when I plug it directly into my ebook2 surface (with HDMI / USB-C adapter).

I hesitate to buy the microsoft HDMI / USB-C adapter because the price is high and I'm afraid it won't change anything.

I'm very disappointed with this purchase. I'm thinking of going back to dock1 and trying to get a refund..

I recently purchased and installed a surface dock 2 device and i too am getting very strange screen turn on behaviour. I have two external monitor screens configured a Dell 2717H (the screen thats giving me the most problems) and a Samsung U28H75x 4k screen. The problem i get is that the Dell screen only comes on at startup once or twice a week correctly. Otherwise i have to unplug the usb-c cable into the SDock2 rear slots, remove and refit the cable into my Surface 3 laptop at least 4 or five times to get it to come up. The screen is showing in Display settings fine but is just not recognised.

I have updated the dock2 firmware a few weeks ago and that worked (used the SEMM file) but things have not improved. If i leave the screens powered up overnight (on standby modes) and surface dock powered up even with my laptop off - then they come up normally every time. Same happens is i dont actually power the dock2 device down overnight but turn off the screens and laptop.

Feels like the dock2 is losing what it knows previously or failing to initialise from a cold boot properly.

The cables I am using are UNI MS Surface laptop and Dock2 compatible ones. I am getting to the point of trying a different cable as its possible that is the issue but need to know which one I have to source, else I waste my money.

Or do i just have an unreliable Friday build Dock2 unit? Its very frustrating and wastes a lot of my time in the mornings getting my setup running.

Please advise
