Detailed description:

Asus customer support just told me that my brand-new Vivobook Pro 15 (K3500PC) does not support multi stream transport (MST) which is required to connect 2 external displays via thunderbolt port.

The laptop has a thunderbolt 4 port (according to Asus product spec), but the thunderbolt specification requires a minimum of 2 displays with 4K to connect to 1 single thunderbolt pc-port to meet the thunderbolt 4 spec certification.

Is Asus cheating its customer?

Can multi channel transport be enabled by configuration?

What's the reason why the TB4 port does not match the expectations? Shortage on chips/controller?
