Displaying an image on screen is performed by submitting a special command to the device's queue. We can't display images using any queues we want or, in other words, we can't submit this operation to any queue. This is because it may not be supported. Image presentation, along with the graphics, compute, transfer, and sparse operations, is another property of a queue family. And similar to all types of operations, not all queues may support it and, more importantly, not even all devices may support it. That's why we need to check what queue family from which physical device allows us to present an image on screen.
