Not able to use 2 external monitors

[andréas]

Hello,

I'm not able to use 2 external monitors with my lap top and I dont know why. My laptop specs tell it is supposed to work: '# of Displays Supported' here : https://ark.intel.com/content/www/fr/fr/ark/products/95443/intel-core-i57200u-processor-3m-cache-up-...

Here are the specs of the devices I'm using :

-> Laptop: HP Spectre x360

Processor: Intel Core i5-7200U 

Graphics: Intel HD Graphics 620

-> HP USB Travel Dock

2 USB 3.0, 1 VGA, 1 HDMI

-> 2 monitors : LG 22EN33T & LG 22M37D

Resolution: 1920x1080

Diagonal: 21.5"

Both VGA (1 plugged on VGA and 1 plugged on HDMI with an adaptator)

The monitor plugged on HDMI is always the one working even when I switch them.

Thanks a lot for your help !

Andréas

Thank you for your answer!

As I said, it is told on my laptop specs that it can support 3 monitors : '# of Displays Supported' (here: https://ark.intel.com/content/www/fr/fr/ark/products/95443/intel-core-i57200u-processor-3m-cache-up-...)

So why cannot it work ?

It is NOT compatible.

Regards.

[andréas]

Thank you but your answer is not very clear. What is not compatible with what ? 

My laptop is compatible with 2 monitors as spectified in the HP link sent. So is it my Dock which is not compatible ?

[banhien]

@andréas 

I did post a compatible list of the dock

Regards.

[andréas]

I'm sorry but I think I still dont understand.

You mean the dock is not compatible with my laptop ? I've been using them together for 5 years

@andréas 

5 years ? On same machine, same setup ???

I say again, I supplied a compatible list already.

Hope this makes sense.

[andréas]

5 years for the dock with my laptop and 1 monitor. But not the setup with 2 monitors which is new and not working.

I'm sorry but you didnt explain what is the list for: is it the list of laptops compatible with the dock?

If so, it is wrong since my dock is usually working with my laptop.

Now with TWO monitors. Can you see the difference between 2 and 1 ? Sorry, I won't go back to this post again

And there are millions or even trillions of notebooks around, they are NOT the same.

Regards.
