The TD40 series mixes ergonomics and performance to enhance the Windows 8 touch-screen experience.
The ViewSonic VSD220 offers tablet-like features with Android software while still working as a regular monitor. Sadly its poor performance, unimpressive display and lack of inputs means it's not great as either a tablet or a monitor.
The ViewSonic FuHzion VX2268wm is a pricey monitor that's low on features, but it has an impressive trick up its sleeve. Although its 2D performance is nothing special, its 3D capability transforms it into a highly impressive gaming display when used in conjunction with Nvidia's GeForce 3D Vision Kit
The ViewDock benefits from above-average image quality, but it's far from perfect: its 'piano-black' finish is highly prone to picking up grimy fingerprints, its audio quality is atrocious and it requires two power cables. Apart from this, it's well-worth consideration
This high-end LCD gets an A for design, features, and adjustability, but its image quality falls a smidge short for the price.
