If you want to work with 2 screens next to each other, it's best to do this on medium duo setup monitors (23 - 25 inches). Most monitors in this segment have a screen size of 24 inches, or 61 centimeters in diameter. This is ideal for a dual monitor setup. With a dual setup, you work in multiple windows at the same time, which increases efficiency. Make sure to choose monitors with a thin screen edge, if you want the screen to flow as seamlessly as possible and choose 2 of the same screens to avoid color deviations.
