Quality Impressions

The adapter produces a crisp and flicker-free image, and its color quality is comparable to that of the primary output for both 16 bit and 32 bit color depths. This is in line with what we expected, since the maximum resolution is only 1024x768.

Display Speed In Windows

As soon as there is a lot of movement on the screen, however, the differences between the primary display and the USB-attached one become easy to identify. Depending on the intensity of the movement, pronounced discrepancies in the speed with which the screen refreshes can be perceived. This effect can be exacerbated by attaching additional USB devices.
