need help - what do you guys know?

No problem.
She told me she is using a Viewsonic Portable Monitor
The one she is currently using is the VG1655. It is good enough for her day to day work and she is only thinking of upgrading to VP16-OLED because she wants to have one that is Pantone calibrated for her Illustrator/Photoshop stuff.

She briefly tried one of those extender that have a support you need to attach to your laptop but she doesn't recommend it. The support broke and she hadn't used it one month. With the Viewsonic, it's like a tablet so you can position it however you want and use the built-in stand to support it.

I asked her if it was running on battery or something and she said she has an AC adapter which makes it run both ways? She told me she can power it from her laptop or plug it with the adapter and use it to power her pen tablet.

She did say it's very portable but is not really meant to be used outside as the brightness might be a little too low if you're using it in a bright daylight setting.

That's about it. Hope it helps. If you have any other question, I can ask her. :)

I am not completely clear on what you need to do.

1. Do you want to continue to power "Loot TV etc" from your current laptop but just want more screen space so that you can continue to use the laptop screen for work without having to share that main screen?
2. Or are you hoping for a second completely independent device that will handle the "Loot TV" chore?
3. I am really confused and it is something else completely! :)

lets try this

Option 1) you want to use your existing laptop, but want to observe additional stuff in separate screen
1-A you may go for 'laptop screen extender' a.k.a 'portable monitor' [](https://www.pcmag.com/picks/the-best-portable-monitors
1-B you may go old school and buy an additional monitor or TV which will require another power outlet. (I am old so thats my way)
Note that option 1 will consume your laptop, so no one can say if work and hobby etc can go together.

Option 2) keep your existing laptop only for work, and want to check your hobby in another device
2-A since you will not need a gaming laptop, lots of notebooks are now with integrated gpu which costs less , also can come in small sizes. Example asus vivobook
2-B I dont know how android tablet will work for your needs, logic is if your cellphone handles what you want to do, android tablet can also do. So look for android 11 tablets or something else
