Surface Laptop 3 Displayport output

Hello,

I haven an inquiry about the USB-C utilized on the surface pro 7 and X, Surface Laptop  3 and surface book 2. 

Does these USB-c connections utilize Displayport ALT-mode and if so what version of Displayport Alt-mode (1.2 or 1.4).

Additional what is the maximum resolution output on one and two external monitors?  I would like to know Resolution, Chroma and bit rate.

Looking forward to your response 

Kind regards,

Jim

Hello Jimmi3,

Thank you for reaching out Microsoft Community. On all the IceLake devices, they will Support USB-C alt-mode at 1.4A (though they don't support 8K). AMD device can support higher.
