I have a device whose video-out is HDMI. My laptop has an HDMI port. My laptop is running Linux.

Can I view the device's video-out on my laptop? How?

Yes you can. However you will need to buy a device known as a frame grabber. One of its input connectors needs to be HDMI (The HDMI connector on your laptop is only used for output).

To repeat: Yes you can with extra hardware.

No. HDMI ports on a laptop are designed to only be used as output.
