A method and apparatus for generating display status information for a computer in a remote computing environment. The method comprises receiving, from a remote computer, a first data set associated with a display image, where the first data set comprises an encoding of a source image to be rendered at the remote computer; decoding, at a client computer, the first data set to generate a first portion of the display image; and determining, from the first data set, a perceptual quality level for the display image. The apparatus comprises: a client resource for receiving display data and decoding the display data; a session monitor for determining a state of the display data decoded by the client resource; and a user interface for presenting the display status information, the display status information comprising the state of the display data.
