Have you ever wondered why the wide screens have invaded our living rooms and computer desks so rapidly? It’s a matter of cost. A wide screen, 16:10 display costs less to produce than a 4:3 screen since. The cost lies in the cutting stage of manufacturing where big panels, which usually measures around 2m x 1.9m, gets sliced up into smaller panels that actually go into displays.
Using wide formats a manufacturer can produce more 16:10 displays than 4:3 displays. The same logic applies to 16:9 in fact this aspect ratio yields even better results. You can get even more displays when cutting the panels in the 16:9 form factor.
The end user then should have a couple of advantages. First, the displays should be the cheaper in purchase cost for the consumer. Second, 16:9 are better to watch movies with since it’s the native format of many TV series and of many movies. Third, high definition like 720p and 1080p resolutions are produced to fit nicely in a 16:9 format, i.e. 1920x1080 pixels and not 1900 x 1200 (16:10) such as in most computer displays. With a 16:9 display, you can watch Full HD movies without the need to scale them.
However, the trend is changing again, as most movies coming out now are produced in even wider format than 16:9. So even now 16:9 displays are becoming an issue for most users who are into serious home theater setups.
The disadvantages however are similar to those that we experienced by switching from 4:3 to 16:9 screens. Smaller vertical space, smaller overall working area compared with screens with the same diagonal size. If a user was using say, a 21-inch 4:3 screen but wanted to upgrade to a 16:9 display, they would have to purchase a 23-inch or 24-inch screen to give a similar working area.
The new sizes that we will see in desktop and notebook displays more and more often will be 14", 15.6", 18.5", 21.6", 23.6". The native resolution ranging from HD (1366x768) to Full HD (1920x1080).
