If you're still juggling everything on a single monitor, this is arguably the best workflow upgrade you can make — literally just plug another DisplayPort or HDMI cable in and your productivity skyrockets! You could run two 24s side-by-side, stack them vertically if horizontal space is tight (which works great for coding with one pane rotated), or even go vertical on a single screen via display settings. If you're a laptop user the hack is brilliant: instead of docking it away, keep the lid open and place it right underneath your main monitor so its keyboard and webcam stay accessible while giving you two usable surfaces. Just account for resolution differences by keeping secondary apps like Slack or Spotify on the smaller screen — and if your machine supports USB-C power delivery you can wire it all cleanly through one dock with a single cable.
Not everyone needs dual displays, though; sometimes a massive single panel is actually cleaner because it eliminates bezel clutter and the need for window management software altogether. The author went back to a 32" 1440p curved display and loved not having apps jump between screens every time they move — but if you go bigger than 27", you should definitely step up to 4K instead of 1440p so the pixel density stays crisp. One thing everyone can improve their setup with regardless of how many monitors is a monitor arm, which gives you height and tilt flexibility that stock stands just don't offer. The immersive factor for gaming on a large curved panel alone makes it worth considering if your desk space allows.
