At $3,000, Vizio’s P702ui-b3 ultra HD TV/monitor is too expensive for every classroom but it can fit perfectly in a lecture hall, graphics classroom or student lounge. That’s because it measures 70-inches from corner to corner and is among the most detailed screens available with 3,840 by 2,160 resolution. Its 72 active zones can be automatically dimmed or brightened to suit the material and there's a high-performance spatial scaling engine for when displaying less-than Ultra HD material. The best part is that the screen has WiFi built in as well as apps for directly playing YouTube videos, NetFlix and other online services. Vizio makes a 60-inch version that can be had for about $1,700.
Regardless of whether you have a cheap 17-inch screen or a professional 27-inch monitor, they all do one thing that isn’t good for you and your eyes. They all give off a lot of ultraviolet rays that can cause macular degeneration and other ocular damage over time. AOC’s Anti-Blue Light technology will be used on the company’s upcoming 76V family of monitors, which blocks 90 percent of the most damaging light without affecting image quality or the screen’s color balance. Look for the monitors later this year.
The latest ActivBoard Touch interactive whiteboards from Promethean have been made for classroom collaboration with support up to six individual touch inputs. This makes it great for group work or having several students doing a problem independently on the board. Available in 78- and 88-inch models, the boards work with Windows, Mac and Linux computers and work with a stylus or fingers. You can use it to teach with PrometheanPlanet’s library of 80,000 educational resources, there’s an optional sound bar and you can order the screen with the company’s marker-friendly Dry-erase surface option.
What does an interactive projector one better? A large screen touch monitor, like the new MimioDisplays. They all can show high definition material, come in 55-, 65-, 70- or 84-inch sizes and have low glare glass coatings so everyone gets a good view of the action. The monitors allow several students to collaborate on screen with finger motions, digital pens and taps.
When HD monitors just aren’t sharp enough, it’s time to consider moving up to 4K ultra-high definition displays. The Asus PB287Q not only fills the 28-inch screen with 3,840 by 2,160 resolution and has the ability to show more than 1 billion individual colors, but the screen has a superfast 1 millisecond response time. It can be connected via a DisplayPort or HDMI and the screen can be moved up and down, twisted side-to-side or pivoted. The display costs $650.
