Thus this USB-C to HDMI cable/adapter cannot be used with a microscope camera/soundbar/oculus quest 2.

We are sorry to tell you that this USB-C to HDMI cable is used for mirroring your video source on your display, thus it will not charge your phone when being used.

Please kindly note that the shell of this cable/adapter is made of alu-alloy for better heat-dissipation and chip protection comparing with the plastic shell. So it is normal for it to become warm when being used.

If you think that the product becomes too hot, please don't worry and contact us with the result. We will provide help as soon as possible.

Please allow the monitor to be completely powered off (*Unplug the power plug) for a few minutes and then turn it back on for connection. Since the monitor is not usually powered off, the HDMI interface of the monitor will generate static electricity accumulation, resulting in the problem of flickering screen.
