Nanovision Mimo 7" USB Powered LCD Monitors
Image Quality & Performance
Even though the Mimo monitors are not in the same league as larger, more-expensive displays, we still ran a few of the more important tests from Everest Ultimate Edition's Monitor Diagnostic Tools. Both displays actually did surprisingly well on most of the test screens. Both lost some detail at the far end of the black and white spectrums, respectively, but all in-between gray tones were easily identifiable. Both displays also suffered from some slight moiré patterns on screens with lots of fine horizontal or vertical lines; but it was not as noticeable as it typically is with larger-sized LCD monitors. Even text was easily readable on the displays.
Where the Mimo monitors faltered somewhat, however, was in their color accuracy. Both displays suffered from a slight blue color shift--which was more noticeable with the UM-740 than it was with the UM-710. We also found the UM-740 to sometimes appear grainy when displaying images with static, solid colors. The UM-740's matte display also seemed a bit muted at times, especially when compared to the UM-710's glossy display. While both displays are rated at 350cd/m2, the UM-710 seemed like it emitted a crisper and brighter image.
We also tried playing back some videos on the displays and were pleasantly surprised to see very little lag or ghosting. Due to the small size of the displays, however, we would not recommend using them much for watching videos. In terms of more mundane, everyday usage, we found that the Mimo monitors did very well at providing an off-the-main-screen home for some of our secondary apps, windows, and tools.
The UM-710 and UM-740 both require drivers to be installed on Windows and Mac systems. The UM-740 also requires an additional driver for its touch-screen capabilities; the Windows touch-screen driver is included with the device, but the Mac touch-screen driver is a $30 option.

The touch-screen worked relatively well, but we occasionally found that the display momentarily lost input, as though we had taken our finger off the display. We also found that the touch-screen input felt somewhat jagged to us--by this we mean that when we performed an action such as dragging a window, the window would actually bounce a bit while we moved it. The screenshot below shows a good example of how the UM-740's touch-screen interpreted what we thought were relatively straight lines.

The UM-740's 1.3-megapixel webcam provided an acceptable image, but we found it to be slightly grainier and darker than other Webcams we've used. Also, the webcam can really only be used when the display is in the horizontal position. When the display is in the vertical position, images captured by the webcam appear sideways--the webcam's orientation does not change when the display's ortientation does. Both the integrated microphone and headphone-out produced decent-sounding audio.
