Citrix's ICA protocol, with its added HDX extensions, supports a high-quality graphics experience for users, which operates well within a range of
network conditions. When bandwidth between server and client gets too low, however, graphics responsiveness might no longer remain acceptable. It's
possible to improve responsiveness in such low-bandwidth conditions by enabling and configuring the Extra Color Compression and Extra Color Compression
Threshold policies within the HDX Policies node of Citrix Desktop Studio. Be aware that enabling this compression results in lower-quality graphics.
