I'd be willing to say it doesn't have hdmi input. Most people want to output from the laptop, not use it as a screen so 99% of them are output only (I've never seen one with input).

You'd need another 3rd party accessory to input the hdmi to your laptop and then software to render it on the screen.

By the time you do all this, it is far far cheaper to buy a small screen to use.
