Editors' note: The Mimo UM-740 is an accessory and therefore was not put through CNET's usual rigorous monitor testing. Its performance rating should not be compared with other CNET-reviewed monitors.
It's not a monitor for everyone. It's definitely not for hardcore gamers. If you use Microsoft Word a lot or are a frequent Photoshop user, however, you'll find that this 7-inch UM-740 LCD is useful. It basically works as an annex to your main screen and provides some extra space for toolboxes, chat clients, or even a media player such as iTunes. It's for any application that you want up all the time, but you don't want to have to choose between it and another as your main app. So if you'd like to have iTunes up and playing at the same time as when you're writing a document or fixing a photo in another program, this is the monitor for you.
The strongest selling point of the UM-740 is that it's compact, light, and highly portable. You'll have to pay for that, however, since it costs about the same as some 20-inch LCD monitors. But then again, you can't carry a regular size LCD around.
The Mimo UM-740 comes in a package that includes the monitor, a USB 2.0 cable, a software CD, and a well-illustrated color manual. The software and drivers that came with the device states that it supports only the UM-430, UM-710, UM-730, and UM-750. After a quick call to the vendor, we found out that the software for the UM-750 is compatible with the UM-740 as well.
Other than that confusing ordeal, the setup was a snap. The monitor connects to a PC via USB cable, which provides both power and connectivity and comes with an extra USB plug to use in an additional USB port, just in case the first one doesn't provide enough juice. Luckily, we never had to use the second plug. The USB port on the monitor itself is in a rather obscure place, making it more difficult than we would like to plug the cable in.
The UM-740 is flexible when it comes to adjusting its position. You can tilt it, rotate it, adjust its height and even quickly disconnect the LCD from the collapsible stand if you want to stick it in your laptop bag.
Once plugged in and set up, the UM-740 worked as we expected. It can be set as an extension of your main LCD, either to the left, right, above, or below. In each case, in order to use an application on the display we only needed to drag its window from the main display to the UM-740's screen.
