Resolution & Screen Size – The Consideration That Many Forget
If your goal is to have more space on your monitors to display more stuff then stepping up in resolution is only useful if you increase the size of the screen.
Why is this? If you have two 24” screens and one has four times the amount of pixels of the other, the pixels on the higher resolution screen need to be a quarter of the size of the ones on the original screen.
This means everything displayed on the monitor is a quarter of its original size, often making things very difficult to read or interact with.
Windows deals with this small pixel problem by scaling up everything displayed on the screen, this works great but reduces the amount of usable space.
Why is this? If you need to make text the same size as on the original 24” screen to be able to read it clearly then Windows has to increase the size of everything back to the size that is was on the original 24” screen.
It does this by increasing the number of pixels used to display things on the screen, a chart which was 400 pixels wide now becomes 800 pixels wide. This scaling uses all those extra pixels you had, resulting in this higher resolution screen only being able to display the same amount of information as the lower resolution one.
The only way to utilise this extra space is if you don’t scale the Windows interface, and the only way to do that (without resorting to using a magnifying glass) is to make the pixels bigger by increasing the size of the screen.
