Despite continuing advances in displays and computers, it’s still hassle to connect your small screen to a bigger one on the fly for a group of students to see. With power and video cables to deal with, I often cross my fingers in hope that it works on the first or second try. With AOC’s E1759FWU display all you need is one cable to share a screen.
The display uses the latest version of DisplayLink software and a USB cable to both power the screen and supply it with imaging data, making it about the easiest display to teach with.
At 9.8- by 16.1- by 0.6-inches, it’s small for a 17-inch display and only slightly larger than Lenovo’s ThinkVision LT1421, which has a 14-inch screen. It delivers 15.1- by 8.7-inches of viewable space, but its 1,600 by 900 resolution, 262,000 color gamut and 10-millisecond video response time are far from impressive. It, however, outdoes the LT1421, which tops out at 1,366 by 768 resolution. Like other USB displays, it lacks touch control.
Setting up the AOC screen is the easy part. You’ll need to load the DisplayLink software that comes on a CD once and then restart the host computer. There’re software versions for Macs and PCs from Windows XP to 8.1, but lacks the ability to connect with an Android or iPad tablet as well as work with any of the major wireless video specs, like WiDi, Miracast or Air Play.
After plugging the included micro-USB 3.0 cable into the back of the screen, you need to plug the two USB plugs on the other end into the host system. It requires a USB 3.0 and a USB 2.0 port. In other words, it will take up most, if not all, of the USB ports on the typical notebook and is impossible to use with a tablet unless you have a USB hub handy.
As the display starts up, the E1759FWU blanks the host’s screen and then in a second or two, the image is displayed on the AOC screen. It automatically sets the right resolution and can be used to mirror or extend the base screen, but the E1759FWU’s adjustments are minimal to say the least. You can change the brightness and contrast, but there isn’t even a power switch. The screen lacks speakers.
The USB screen’s black plastic case weighs just 2.8-pounds and comes with a padded cover, making it perfect for grab and go lessons or even teaching outside on a warm day. On the other hand, the E1759FWU has one of the best stands in the business. Its pull-out easel leg makes for a sturdy base extends up to 10.5-inches in the back. You can tilt the screen from a nearly vertical angle to 30-degrees
It can be set up horizontally or vertically. The magic happens when you change its orientation from landscape to portrait mode (or vice versa) because the screen’s image automatically rotates to accommodate the new view of the world. If you want to, the display can be attached to a wall- or table bracket with its 100-millimeter VESA mounting screw holes.
All told, the image appears a little dull and the display puts out 163 candelas per square meter of brightness, or about one-third off of its specification. Its colors look accurate but some appear to be washed out and grayscale images have a blue cast to them.
It’s a power-miser that consumes less than 10-watts. That means that it can be used with its host computer running on battery power. This and the fact that the screen comes with a 3-year warranty make it a powerful screen for schools.
