Monitors do more than provide good graphics performance. They also can reduce eye strain and make it much more comfortable to spend a lot of time at your computer.
AOC, Samsung and other manufacturers offer great options. Stands and accessories allow you to customize your setup so that it’s as ergonomic as possible, allowing for comfort and better health over the long term. If you tend to have a lot of windows open at the same time, consider going bigger on size to make them more manageable.
