HP Remote Graphics Software 5.4.8 User Guide

Remote Computer monitor blanking overview
New in RGS 5.0, this feature blanks the Remote Computer monitor (if one is connected) when the local
user establishes an RGS connection to the Remote Computer and logs in—in other words, becomes the
primary user. This feature is provided for security, to ensure that the primary user’s desktop session on
the Remote Computer is not visible on a monitor connected to the Remote Computer. For details on
monitor blanking, see
Remote Computer monitor blanking operation on page 107.
Video overlay surfaces
When the Windows Sender is installed on a computer, video overlay surfaces (also known as overlay
planes) are disabled on the computer. Some media players that use video overlay surfaces will not
display correctly. This can often be resolved by disabling the use of video overlay surfaces in the media
player.
Most OpenGL applications will detect the disabling of overlay surfaces, and will work correctly.
However, if your OpenGL application attempts to use the disabled overlay surfaces, it may display
incorrectly. If this is the case, check to see if your OpenGL application provides a mechanism for the
user to manually disable the use of overlay surfaces.
