Available in 55- and 65-inch models, Samsung’s Flip 2 not only shows UHD resolution, but the screen’s height can be adjusted and up to four teachers or students can write on it at once. Just walk up to the screen, grab the pen and start writing, open an image or work through a PowerPoint lesson. With a feel that’s close to pen on paper, the Flip 2 has outputs to transfer the image to a projector for a larger audience. The 55-inch model goes for $1,200 while the 64-inch one costs $2,600.
