Client graphics settings

This option enables the quality of graphics displayed by the remote application or desktop.

From the color-depth drop down menu, select the preferred range. The available options are 16-bit color and 32-bit color. NOTE: Low color depth is more effective when using low bandwidth.

Enable 'Disk based caching' to allow the graphics to be temporarily saved to the local disc cache.

Enable Lossy compression to degrade the quality of graphics for maximum compression and responsiveness.

Enable HDX 3D Browser acceleration to allow Microsoft IE to be handled by HDX 3D virtual acceleration channel.

Enable HDX 3D browser acceleration lossy compression to allow Microsoft IE to degrade the quality of graphics for maximum compression and responsiveness.
