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.

I bought the Elgato Cam Link 4k for $80 and it's been working ok so far. While getting an external monitor is more cost effective, I care more about portability since I travel often and so it's well worth it in my case. Also the delay is only a couple of ms so it's perfectly acceptable for office work or just having Discord up or something.
