Yeah that's why I was asking lol. But for that use its perfect to have it directly hooked up to the PC. And yes, sometimes it can be nice to have a big screen for some random apps.
I didn't know my current one could be mounted so I always thought I have to buy a new one before I can even think about an arm. But now trying the arm first with what I have sounds more reasonable.
But idk which arm to buy now lol. I think two separate arms with gas springs are more flexible but it might look weird if I end up using only one. Using a vertical tube allows attaching arms as you need but I think it restricts the vertical alignment more than two separate arms. Anyway, I have to figure that out somehow. Thanks a lot!
You could also think about Lunati modding because it uses Lua for this, an easy-to-use programming language. https://docs.luanti.org/for-creators/creating-mods/
