I've been talking about the Samsung LD190 since(and by "talking about" I mean I've mentioned it once and really haven't since then).
Samsung is pushing the LD190N as a companion monitor for use with a laptop. Meaning, they expect you to use it in extend mode when in need of extra screen space.
The monitor includes a 18.5-inch, 1360x768 resolution screen, VGA, and upstream USB. The USB includes DisplayLink technology, which allows you to circumvent the VGA connection altogether.
Check out the pics below of the $150 companion piece and look for a full review of Samsung's LD190 soon.
