This monitor runs Android OS on its own, but can also hook up to a computer and act purely as a touchscreen monitor.
Pro Can be used as a stand-alone Android computer
This monitor has all the internals needed to run Android 4.3.1 Jelly Bean (Tegra 4 processor, 2GB of RAM, 8GB of storage). This gives you the flexibility to run Android apps and games, or use it as a display for your computer or laptop. If you have limited desk space, or want a touchscreen on a budget (without the need to buy a computer), the ability to use it without a computer is a very intriguing option.
Pro Integrated peripherals make this a complete-package monitor
Built-in are two 2 watt stereo speakers, a 2MP webcam, as well as a microphone. These allow you to use it as a stand-alone Android device for Skype, Google Hangouts or other video chats, or they can be used in place of dedicated hardware when plugged into a computer (although dedicated hardware would provide better quality).
Pro Very stable and flexible base and stand
The monitor is help up by a traditional looking stand with a square base. The stand can be raised or lowered slightly (which the other touchscreen monitors in this category can't do), and the display can be tilted 90 degrees so that it can be perfectly vertical, or perfectly horizontal (or anywhere in-between) depending on your set-up preferences.
Pro Good display quality
The contrast ratio is important for having a wide depth of colors available, and the ViewSonic Smart Display doesn't disappoint with a very good 1000:1 contrast ratio. Response time is similarly good, and will display images 5ms after receiving them. This response time is good enough for even high-end gamers, but will also appear to make the entire system a bit more responsive and faster.
Con Uninspiring design
This monitor looks like any old monitor. Other monitors in this category have much more interesting designs, and add form to the function of adding a touchscreen monitor to your setup. The un-original base and plastic bar beneath the screen are both aspects you'd expect to find on older, cheaper monitors but are still present here.
Con Android version is dated
Android Jelly Bean 4.3.1 was released in July of 2013, and is a dated operating system. While core features like web browsing will still work fine, some apps require new APIs (application programming interface) which are only available in newer versions of Android. If there are Android apps you want to run, make sure to check their compatibility on the Play Store
