The thing that honks me off about these products is that the almost always lack support for high-res monitors! What if you have 2560x1600? It won't drive that at full resolution. The DisplayLink chipset supports that size, but you need to install one more RAM chip, driving the cost up by maybe $2. Especially with 4K displays becoming affordable, this situation is almost inexcusable. The people most likely to buy a product like this are also the ones most likely to invest in a larger monitor.
