Sort of. To enable touch on a PC that doesn't support USB-C DP Alt Mode (ie the vast majority of desktops), you have to connect a USB 3.0 Type B cable (not included) alongside either DisplayPort or HDMI to the target machine. Alternatively, you can connect the included USB-C cable to a laptop that supports USB-C DP Alt Mode and have 65W power delivery, touch, camera, mics, display output and touch/pen support all rolled into a single cable.

Please note that the touchscreen part of the display is only compatible with Windows and not MacOS.

The Viewsonic ID2456 is a 4K touch monitor with MPP 2.0. For a classroom environment, 4K will make text feel more crisp and detailed, especially if your pen inputs are going up to a large TV or monitor as you write on the display. The 16:9 aspect ratio also plays nicely with any projector or TV you're presenting to. The Pana only supports MPP 1.0; the principle difference is that MPP 2 support pen tilt detection, helping penmanship and brush strokes feel more natural but might be unnecessary for your purpose. The Pana's strong suit is the 21:9 wide ratio that makes multi-tasking very useful without cramping each window. For your particular use case I would suggest the Viewsonic.

I've confirmed by purchasing this monitor that it works properly with that support Microsoft Pen Protocol! This includes the newest Surface Pens and the Wacom Bamboo Ink 2nd Gen which I tested on the monitor.

The Jupiter Systems Pana 34 21:9 Ultra-Wide 34" Multi-Touch Commercial Display (BH # JUPANA34) supports Windows / Mac OS / Android / Linux. Updating may require downloads of drivers for optimal operation.
