Do you need an external monitor? The conclusion
Whether you need an external monitor depends on how you use it.
Want to increase work efficiency → Necessary
Work for long hours → Necessary
Mainly browsing or watching videos → Not necessary
Reasons why an external monitor is necessary
① Your workspace expands
Because you can open multiple windows at the same time, it becomes easier to work while researching or working while looking at reference materials.
As a result, you switch tabs less often, and your work efficiency increases.
When you actually use one, the reduction in screen switching alone significantly reduces stress.
It is understandable why many people cannot go back once they have used one.
② Your posture improves
With just a laptop, your gaze tends to drop, which puts a strain on your neck and shoulders.
Using an external monitor raises your line of sight, so
you will be less likely to get tired even during long work sessions.
3. It becomes easier to focus
By expanding your workspace,
it becomes easier to organize your screen, reducing unnecessary actions.
People who do not need an external monitor
It is not necessarily needed by everyone.
Characteristics of people who do not need one
Mainly use it for browsing and watching videos
Short work hours
No desk space
Prioritize portability
In these cases, there is no problem if you do not go out of your way to introduce one.
