   heuristics determine that it would likely outperform lossless compression.
 
+`compress-level`
+: Controls the level of compression requested of the VNC server when either
+  tight or zlib encoding is in use, on a scale of 0 to 9, with 0 being no

 #### VNC Repeater
 
 There exist VNC repeaters, such as UltraVNC Repeater, which act as
