I’ve used a number of screens for 20 years. This is what really issues
In fact, all of it begins with the screens themselves. Right here’s the way you decide the perfect screens for a multi-monitor setup within the web’s favourite format, a numbered record.

Step One: Display screen Dimension
This one ought to be straightforward. Decide two screens of the identical dimension, and so they’ll look good subsequent to 1 one other. Decide two screens of the identical dimension and determination, and so they’ll match completely. For instance, in case you’re beginning with a 27-inch, 1920×1080 display screen, simply purchase one other 27-inch, 1920×1080 display screen, and your bodily desk area will match. However the expertise is greater than bodily — your desktop wallpaper, home windows, textual content, and different person interface components will match, too.
The simplest factor to do is simply purchase two of the identical mannequin monitor. Or in case you’re already beginning with one, purchase the identical mannequin once more. That’s not at all times attainable, although. Perhaps you’re in search of a extra inexpensive choice for a secondary display screen — say, a main gaming monitor with a greater or quicker panel, and a second one only for info. (Extra on that later!) Perhaps your unique monitor isn’t made anymore. Go for a similar dimension and determination if you’d like them to match, no less than nominally.
Brateck
There’s one very last thing to contemplate right here: side ratio. That is the ratio of your monitor’s size to its width. Most screens use the usual 16:9 today — that’s the identical form LCD televisions have been utilizing for over twenty years. However there are exceptions. Some work-focused screens use 16:10. Ultrawide screens stretch out to 21:9, or generally even 32:9 (that’s, two commonplace screens aspect by aspect) for the large screens. That is the place issues can get difficult, so transfer on to step two.
Step two: Display screen density
DPI or PPI stands for Dots Per Inch or Pixels Per Inch. It’s a small element, generally not even listed on a monitor’s specs web page. However it’s important to understanding how an excellent multi-monitor setup works.
Let’s take a look at two Dell screens for an instance. The display screen on the left beneath, the Dell 27 Plus S2725HSM, is 27 inches and 1920×1080 — just about the usual for any finances show in 2026. The one on the proper is the Dell 27 Plus S2725DSM. They appear equivalent, apparently having precisely the identical physique, stands, even colours. However the S2725DSM on the proper has a boosted QHD decision, 2560×1440. So its pixel per inch score, 108.8, is greater than 25 p.c greater than the 1080p monitor, simply 81.6.
