3. Is screen resolution important?

Resolution is an important factor because it greatly affects the image quality and detail of the displayed content. High video resolution displays more pixels in the same space. This contributes to making the image sharper and more realistic. From there, you will have a better experience when watching movies, playing games, or working with graphics.

The importance of image and video resolution

However, screen resolution is not always important. For small mobile devices like smartphones, you may not be able to see as much of a difference in image quality as you would on a larger screen. The phone screen only needs to display a sufficient resolution to ensure sharp quality and not cause eye strain. If the resolution is too high, this can result in wasting memory or battery and not provide a significant difference in user experience.
