My laptop runs AutoCAD and various Autodesk drafting/modeling programs. I'd like to buy a second monitor to help me work with multiple files/drawings at the same time.
What second monitor can I buy that...
- is designed specifically for use as a second monitor,
- has a diagonal of about 16" (maximum of 20"!),
- is relatively portable (this will likely be used with a laptop), and
- is under $150?
