I love having a lot of screen space on my computer desk. I have the Macbook screen but I’m used to having more with the old iMac and a 1920 x 1080 monitor connected to it. So when I got the MacBook I went for the LG 4K monitor and it’s working really well.
I have a couple of apps to choose from to adjust the screen resolution. Mostly I use the default largest available and occasionally swap to a lower resolution so I can see things bigger. It depends on if I can change the size of the text in the app I’m using.
