Why are all monitors widescreen now?
The short answer is that 16:9 widescreen aspect ratio is the most common option for computer monitors and TVs today. That's because it fits best with most modern movie and video content, and also because it makes the typical modern work day easier.
Why widescreen is better?
This means the width-to-height ratio took on a longer, more rectangular format versus the usual, boxy display. The elongated widescreen monitor delivers an immersive effect with enhanced picture quality. Most widescreen monitors use the newly established 16:9 aspect ratio to display its content.
Is 16:9 better than 16 10?
If you're used to using a 16:9 screen and you try a 16:10 or 3:2 display of the same size, you probably won't want to go back. You just have a lot more room, and it's a much more efficient use of screen space. But this CES showed that 16:10 and 3:2 displays are inching closer to the mainstream.
