I once tried to do a multi-monitor setup, my tablet was actin funny cause it acts as a mouse, and would just stretch my lines out and it got pretty annoying. although i do have my old pc hooked up to the same monitor for when i work on games n stuff
I used to use a dual-monitor setup at school. It was pretty handy when doing intensive things like video editing (being able to follow a tutorial in real time while seeing what you're doing on the other screen? Feels so good). The rest of the time, though, I just used the second screen as a way to show off another wallpaper I really like.
At home, I have a laptop, but it's 1920x1080 resolution so I can basically fit two windows on it anyway.
Dual monitor is very helpful. For reference, streaming, watching videos and all around general multitasking. Hell you could even put a game on the 2nd monitor and doodle during its idle times if the game has any.
It REALLY helps with juggling multiple things at once. If you're the kind of person who bounces around multiple windows a lot, it makes things hell of a lot easier. Take, for instance, just using a reference while you work in PS or whatever because you're too poor to afford one of those beaitiful cintiq things. I also enjoy them for non work purposes too. For example, I got really into the Discord chat program, and I always keep it fullscreened in my spare monitor so I can keep an eye on it while I do other things. I also DM a Pathfinder game in Tabletop Simulator, and having a second window to reference sheets in is WAY better than alt tabbing near constantly to keep up with what's happening.
Depends on your definition of productive. For an artist, I can see how it could increase productivity by having reference photos/whathaveyou on one screen and your paint program on the other. I'm not an artist [yet(?)] And I still think having dual monitors increases my "productivity" alot. They are incredibly useful, and if you're an artist i'd highly reccomend picking one up
All depends on the size you need things open at, the number of things you need open, and how much it really matters if you're good at alt-tabbing quickly. I mean if all else failed and you were just using it for references which you'd have open long enough to worry about screen burn you could be asking yourself is if it would make you more productive to print the references and pin them up next to your monitor. Or if you purchased a streaming box of some sort and put your monitor next to a TV. Not saying either are the best idea in comparison mind you, just pointing out one could say they are.
Short version, if you need communication clients open, and a lot of them open at once I mean, probably good to have a monitor or two just for them. Reference use is hit or miss based off your needs to consult it, as someone who codes can be a bit more useful for me at least to have some things open on both screens at once when I can afford the space.
When I first got my second monitor, I'd actually say it distracted me. I hadn't really figured out how to use it properly.
Now I pretty much only use the second monitor for things that I want to look at occasionally. It's definitely useful. One of my favorite uses is having a Youtube video to listen to while I work, or just do something that's not particularly engaging. I like being able to watch the video if it becomes relevant.
I use a multi computer setup, so I'm a bit weird. It's nice having two separate computers doing two separate tasks, and if I have a crash it only effects a fraction of my current work load. It does make me more productive.
Yes. It makes it easier to check up stuff on the other monitor without slowing down stuff in the one I'm working on. Only exception would be doing streams, since both computers share the same connection, though I'm not sure how much of a slow down it produces. lol
