I use them for monitors and have a cheap surround screen system! They're fantastic. I also protect my eyes with timed filters using f.lux (Windows) and "night lights" for Linux. Call me old-fashioned, but they are way handier, especially if you are a maker and fiddle with electronics and repairing things, eg. rpis. More inputs, simpler, more intuitive. That, and Linux use made me really hate how newer tech often tries to decide what I want rather than letting me choose. The more I make my own systems, the more I wonder how harmful that loss of agency is. I love making old tablets and things useful again.
