New USB C Hub adapter (SKU A8334) HDMI question


I’ve just purchased this adapter mainly for the HDMI input along with the USB A connector with a HP Spectre x360 on Windows 10 Home.

When plugging in the HDMI, I can only extend to an external screen up to 640 x 480 and there is no other option. Also the resolution is not great with a very grainy picture.

Has anyone experienced the same problem and fixed the issue?
