Generally iRAPP simply mirrors the Mac OS X Graphics system. "iRAPP Server" can provide any screen resolution and iRAPP Client can display a workspace with any resolution. However, iRAPP can set only screen resolutions supported by Mac OS X and the current hardware and software. Also Mac OS X has some graphics restrictions for hidden user sessions. Hidden user sessions depend on the current resolution of the user session that is currently visible on the Mac monitor. All of the above reasons force iRAPP to provide restricted resolutions list to the PC-side.

For example:

The current visible resolution is 1680 x 1050. In a case where iRAPP connects to the user session that is not visible on the remote screen, then Mac OS X allows only a restricted resolutions list:

• 800 x 600
• 1024 x 768
• 1680 x 1050

In a case where iRAPP connects to the current visible session then Mac OS X allows a full non-restricted resolutions list:

• 800 x 600
• 840 x 524
• 1024 x 640
• 1024 x 768
• 1280 x 800
• 1344 x 840
• 1680 x 1050

Unfortunately, we have yet to find a solution to break the Mac OS X restrictions for hidden sessions.
