Has anyone used portable monitors with PS5 for travel or compact setups?

With more compact gaming setups becoming popular and portable monitors getting surprisingly good specs lately (144Hz, HDR, USB-C power, etc.), it feels like pairing one with a console could be a solid alternative to lugging around a full TV.

I’ve been seeing a lot of portable monitors marketed toward laptop users, but not much real-world feedback from people using them with a PS5 specifically. On paper, it seems straightforward since the PS5 just needs HDMI, but I’m wondering how well it actually works in practice — especially for travel or temporary setups.

I’ve got a PlayStation 5 and I travel fairly often between places (sometimes staying a few weeks at a time). Bringing a TV isn’t realistic, and relying on whatever random hotel TV is there can be hit or miss (input lag, no accessible HDMI ports, weird scaling, etc.). I’m considering grabbing a 15–17” portable monitor to throw in my bag along with the console.

A few things I’m unsure about and would love advice on:

Do portable monitors handle the PS5’s output well (1080p vs 1440p scaling, HDR support, etc.)?

Is powering both the monitor and PS5 in a travel scenario a hassle?

Any noticeable input lag compared to a decent gaming monitor or TV?

Are built-in speakers usable at all, or should I just assume headphones are mandatory?

Any specific models you’ve had good (or bad) experiences with?

I mostly play single-player games but occasionally hop into multiplayer, so decent response time matters. I don’t need 4K necessarily — stability and simplicity are more important.

Would really appreciate hearing real experiences before I pull the trigger on one. Is this a practical setup, or does it sound better in theory than in reality?
