Can I use a spare laptop as secondary screen with an Elgato/HDMI USB capture card? (self.pcmasterrace)

I know laptops don't have HDMI In ports but I was thinking I can buy an Elgato USB adapter or some HDMI capture card to act as a monitor with OBS.

I've seen videos of ppl recording gameplay using the capture card but is it possible to extend my laptop display as well with the adapter?

Right now I'm using the Windows wireless display feature and it works well but there's still a bit too much latency and it times out whenever I alt+tab windows so I'd prefer a wired solution.

Oh didn't realize it would be that much latency. In that case I'll just stick with my current "projecting to this PC" method where it's a couple milliseconds of latency.

I thought it'd be less latency with the adapter since it's wired but I guess it needs to process the video which adds the latency.
