I have USB-3.0 ports on my computer and I need to get an extra HDMI 2.0 port to connect another 4K screen.

I have option to buy USB-3.0 to HDMI connector and it will cost me around $100.


I can by a connector USB-3.0 to USB-3.1 (type-c) for $5 plus another connector USB-3.1 (type-c) to HDMI for another $10.

If it will work I'll save around $85.

But will it work? Why?


I'll be happy with a HDMI, DisplayPort or DVI and (2560 × 1600) is fine, if there would be solution. But (1920 × 1080) - is not enough.

    There are $20 USB3 to HDMI adapters on Amazon. However, your not going to get 4K resolution out of HDMI 2 over USB. – Ramhound May 17 '19 at 4:13
  • Yes, they only offer (1920 × 1080) it is not enough for modern monitors. – Yevgeniy Afanasyev May 17 '19 at 4:17
  • Even USB-C may be "not display enable". – Yevgeniy Afanasyev May 17 '19 at 4:25

    Seems like you have answered your own question. USB Type-C will still be limited by the fact it’s USB 3. You gain no performance from the Type-C connector. The $100 adapter will absolutely not get you 4k – Ramhound May 17 '19 at 4:26

    The only 4K Type-C adapters are actually Thunderbolt 3 adapters. – Ramhound May 17 '19 at 4:30

Please note that not all USB-C ports are able to carry a video signal. You will need to connect to a port that is labeled with one of the icons below.
