1. A method for updating a remote display, comprising:

  • receiving a plurality of display frames of a source display;

    storing, using a computer processor, at least some of the display frames in a queue;

    selecting a first image compression algorithm from an algorithm database comprising a plurality of image compression algorithms, the plurality of image compression algorithms comprising a lowest quality (LQ) image compression algorithm and a highest quality (HQ) image compression algorithm;

    performing, using the first image compression algorithm, a first transfer of a first display frame in the queue to the remote display over a network connection based on a first bandwidth of the network connection, a size of the first display frame, and sizes and times of display frames currently present in the queue,determining that the first image compression algorithm is the LQ image compression algorithm;

    determining that each display frame in the queue has been transferred to the remote display via an image compression algorithm of the plurality of image compression algorithms;

    selecting the HQ image compression algorithm from the algorithm database; and

    performing, using the HQ image compression algorithm, a second transfer of the first display frame to the remote display over the network connection based on a second bandwidth of the network connection, the size of the first display frame, and sizes and times of display frames currently present in the queue.
