For that reason, I think the eLearning canvas should be set up to use a 16:9 aspect ratio as opposed to 4:3. The aspect ratio of an eLearning canvas designed to be viewed on its side, or in landscape mode, is the ratio of its longer side to its shorter side. If you go with a 4:3 aspect ratio (4 pixels across for every 3 pixels in height), you're working with a shape that is tending toward a square. Both 1024x576 and 1280x720 are 16:9 ratios.
