Dell 3475 as passive monitor

Hello,

At my primary residence, I use external monitors with my XPS 15 9510 laptop. There is never a problem, especially given the DP 2a + Thunderbolt 4 capabilities of the XPS. My question: I visit a relative in another state several times per year, and I’ve set up my old 3475 there and, given the portability of the XPS, would I be able to use my 3475 AIO as a passive external monitor for my XPS when I am at that location? I’ve noticed that there is only 1 HDMI port on the 3475. I’m guessing it’s output only, but I’d like to see if it’s a possibility to take advantage of the 3475 as an external monitor for the XPS 15. Thank you!
