Surface Pro 7 extending display to two monitors via USB-C port

I have been trying to connect my Surface Pro 7 to two external monitors via the USB-C hub (via HDMI cables). Sadly, with no sucess. Now microsoft central boldly claims that the Surface Pro 7 can support 2 4k monitors: https://www.windowscentral.com/can-surface-pro-7-power-dual-4k-external-displays. Is this actually true!?

However, all the troubleshooting and comments that I can find online points to the SP7 only being able to extend to 2 monitors independently via the surface connect port via a surface dock.

FYI the two screens I am trying to connect are:

Dell S2319HN (1920 x 1080, 59Hz)

Iiyama PL2492H (1920 x 1080, 59Hz)

Can the SP7 support extending to 2 monitors independently via the USB-C port? or does the advert for the SP7 supposedly supporting 2 4k monitors: only apply to mirrored displays?!

    Sorry, this doesn't answer my question at all!

    Daisy chaining won't help my situation, as my Dell screen doesn't support it.

    Also can't you only mirror displays when daisy chaining? My main issue is that although when using the USB-C hub (which I have tested with a seperate PC with USB-C input - where the same two monitors can be identified as seperate screens and can project different images - i.e. extended displays, lets call this image A and B on screen 1 and 2.) with the SP7 the SP7 can extend its display but I have the SAME image on both screens and it is unable to identify screen 1 and 2.

    How does the HDMI 2.0 cable help? I'm not particulary concerned about the refresh rate or image quality at the moment (or the inclusion of sound)  I just want the SP7 to recognise the 2 external screens seperately.

    I have already looked at Troubleshoot connecting Surface to a second screen in detail, and it doesn't solve my problem as the SP7 finds a second screen fine via the USB-C hub (with 2 HDMI inputs) but refuses to identify or recognise the 3rd screen.

    Good Morning,

    This is what I found but I am running into the same issue. It appears that the USB-C Travel Hub was intended only to display one monitor. As is mentioned on the product page under Tech Specs.

    Hello Way Way Moinet,

    Thanks for reaching out Microsoft Community and posting your concern here. 

    Technically, Surface Pro 7 supports daisy chain using the USB-C port. It also projects with a maximum 60Hz refresh rate and 3840x2160 resolution when two external displays connected. Also, for the USB-C to HDMI adapter, we recommend using the HDMI adapter with a HDMI 2.0 cable or higher. HDMI connections can also transmit audio signals. We also recommend you use Microsoft’s USB-C adapters on the devices equipped with the USB-C port. See Troubleshoot connecting Surface to a second screen for more details and troubleshooting guide.

    If this answers your question, please let our Community know by marking this post as an answer. Otherwise, don't hesitate to respond to this thread if there’s anything else that needs to be addressed.

    Kind regards,

    StevenK
