Menu path: Setup > Sessions > NoMachine NX Client > [Session Name] > Unix Display

Here, you can define the properties for image transmission from the NoMachine NX server to the NoMachine NX client.

The image transmission properties can also be defined on the server side. If a server-side setting competes with a client-side setting, the server-side setting will be effective.

This area is active if the parameter Setup > Sessions > NoMachine NX Client > [Session Name] > Server > Session is set to "Unix".

Display: Size of the display area that is used for the session.
Possible values:

  • "640x480"
  • "800x600"
  • "1024x768"
  • "Available area": The entire display area is used for the session. The taskbar is not visible.
  • "Fullscreen": The session will be shown in full-screen mode, i. e. stretched across the entire screen.
  • "Custom": The Width and Height can be freely defined.
  • "Multimonitor fullscreen": The session will be shown in full-screen mode on all available monitors, i.e. stretched across the entire screen of each monitor.

Width: Width of the display area for the session. (Default: 800)

Height: Height of the display area for the session. (Default: 600)

Use custom settings

☑ The image transmission properties can be changed on the client side.

☐ The image transmission properties are specified on the server side only. (Default)

Use both JPEG and RGB compression: JPEG compression (results in losses) as well as RGB compression (loss-free) will be used. The level of JPEG compression will be adjusted dynamically depending on the compressibility.

Use JPEG and RGB compression, and use custom JPEG quality: JPEG compression (results in losses) as well as RGB compression (loss-free) will be used. The level of JPEG compression is specified by the parameter JPEG quality.

Only use JPEG compression: Only JPEG compression (results in losses) will be used. The level of JPEG compression will be adjusted dynamically depending on the compressibility.

Use JPEG compression and custom JPEG quality: Only JPEG compression (results in losses) will be used. The level of JPEG compression is specified by the parameter JPEG quality.

Only use RGB compression: Only RGB compression (loss-free) will be used.

Use plain X bitmaps: The images will be transmitted as bitmaps without compression.

JPEG quality: If Use JPEG and RGB compression, and use custom JPEG quality or Use JPEG compression and cusom JPEG quality is enabled, the quality of images in JPEG format can be defined. (Default: 6)
