[Solved] The USB C to HDMI adapter does not work

Hi,
Windows detects the usb c to 2 hdmi adapter as a composite device, so the 2 monitors connected to it do not work at all because the computer cannot see them.
How can this be solved?

Hello. What did you connect this USB C 3.1 adapter to which laptop? Or to the phone?

Do laptopa Acer Aspire R5-571TG-7229

This is the adapter that should work for you. https://www.x-kom.pl/p/322855-przejsciowka-qoltec-adapter-usb-31-typ-c-do-hdmi-usb-usb-c.html

Only this adapter is for 2 monitors and I would need one. I have exactly this one:

Have you read the description of this adapter? Because he writes like this "Make sure you have checked the compatibility of your device, whether it meets all requirements for the operation of a specific i-tec product, especially video output (Display Port Alt mode) and / or Power Delivery. If your device will not be fully compatible , Your new i-tec product may not work properly. Specifications of the device (eg USB port) can be found in the user manual that came with your notebook / tablet / smartphone or through the customer service of your device manufacturer. However, if you still have doubts, contact with our service. "

It turned out that the adapter is not compatible with the laptop, as they provided in the store. Of course it was returned.
