The display is also extremely high-quality. It fully supports 4K resolution feeds sent to it via either of its three HDMI inputs or the USB-C interface. The USB-C input supports DP Alt Mode as well as 5V/3A power and acts as an upstream to peripherals that can connect into the USB-A that sits beside it, and it can do that with an eight-millisecond response time and a 60-hertz refresh rate. In our testing, there were never any artifacts or blurry lines even when displaying full-screen, Ultra HD-quality feeds. Using it for less-intensive applications, like displaying photos and text, was similarly flawless.
For even more display options, there is a dedicated media player that can run via one of the USB-A connections or the 32-gigabyte internal storage to schedule, loop and play content as the user sees fit.
Even the overall construction of the PN-ME432 has clearly been designed for public use. The entire frame of the display is made of a lightweight but sturdy metal alloy. That provides the stability needed to attach it to a wall or mount it. It’s also designed to be used in either a horizontal or vertical configuration, so you can place it wherever it’s most needed, even if space is limited. You could also orient the display to maximize the readability of whatever type of information it will normally be showing; for example, long lists might look better in a vertical configuration.
In addition to being a high-quality, rugged display, Sharp also provides a lot of useful management capabilities for getting the most out of the PN-ME432. The NaViSet Administrator 2 software is easy to use and allows for complete manipulation of the monitor to change power settings as well as the information being displayed. The software is even designed to be used as a central command center for an entire fleet of PN-ME432 displays. It can also support a network of NEC- and Sharp-branded displays and projectors.
A commercial display like the ME432 is designed to last for many years, especially if you use the included management software to dim or power off the display when not in use. However, even if the hardware will last a long time, the software that drives it could change.
With an extremely accurate and high-quality display and excellent management and control capabilities, the Sharp PN-ME432 is a very powerful tool for use as either a single digital sign or as part of a campuswide signage network. But perhaps the most impressive feature is the price. Many commercial displays, especially large ones above 40 inches, cost thousands of dollars. But the PN-ME432 is available from CDW at a price that can help campuses build entire digital signage networks without breaking the bank.
