The 16:9 aspect ratio is no longer that unusual, both for computer monitors and for TVs. While there are still a select few computer users that loyally stick with 16:10 screens, the majority of displays on the market are 1.78:1 or 16:9. There's more, however. At the IFA fair in September 2012 LG announced a monitor with a 21:9 aspect ratio. This imposing 29in screen reached our doorstep recently, and we put it though the usual series of tests. So what's the point of such a wide screen?
There is a reason why 16:9 is so popular; it basically corresponds to the 1.78:1 aspect ratio used for HDTV broadcasts and many movies. In the world of computers 16:10 was briefly the standard, but that has since been replaced by 16:9 panels. These support the Full HD resolution, and from a manufacturing standpoint you can get many more 16:9 panels from a glass wafer than you can 16:10 panels.
For televisions, 16:9 has been the dominant aspect ratio. There are a few outside Europe, but we're ignoring those for this article. The one notable exception is the Philips 56in 21:9 TV. Hardware.Info tested a number of these, and concluded at the time that the new format is great for super-widescreen movies with 2.4:1 aspect ratio, but not very efficient for conventional broadcasts.
LG now has a monitor with the 21:9 aspect ratio. The EA93, or 29EA93-P as the entire product designation reads, has a screen of 29in and a resolution of 2,560 x 1,080 pixels. The mathematically inclined of you will notice that this is two times 1,280 x 1,080, a resolution that comes close to the 1,280 x 1,024 5:4 aspect ration of the early 17in and 19in TFT monitors. You basically get two of those almost-square screens next to each other, without a bezel between them.
This can be useful for a number of applications. Take very large Excel spreadsheets, for example, but also video editing with multiple windows, photo editing, and of course gaming. You can read the rest of LG E93 monitor preview on Hardware.info.
