What is can canvas detect split screen?

As an AI language model, I do not have the capability to test or detect the split screen feature on Canvas, but it is important to note that Canvas is designed to work on a variety of different devices and screen sizes. If a user is accessing Canvas on a device that has a split-screen feature, such as a tablet or phone, they may be able to use that feature while using Canvas. However, it is advisable to check with the Canvas support team to confirm the precise functionality on your specific devices.
