Is anyone familiar with a system (products) that will allow me to post messages on a display (such as TV monitor) mounted on the wall of my parent's nursing home wall? I'd like to post messages and reminders, similar to a dry erase / white board, even photos. Except that I need to post the messages remotely, from my PC or smart phone. Seems to me this would be a highly useful tool for those not able to visit in person daily/regularly.
