Dell ThinOS 2402 Administrator’s Guide

Configure the display settings

1. From the desktop menu, click System Setup > Display.
   The Display Setup dialog box is displayed.
2. In the Display Setup dialog box, configure any of following options:

   

   • Select the Mirror check box to enable all connected displays to use the same display settings configured on the primary display.

     If you clear the Mirror check box, the Span mode is enabled.

     Blocks that are displayed on the screen represent the number of displays connected to the thin client. Each block represents a single display screen.

     

     Every display contains a unique display order number and display configuration. You can move the blocks horizontally or vertically and construct the multidisplay layout in mixed directions. To construct a new display layout, move the blocks to your preferred position, and click Apply. A new display layout is created. However, when the block is moved to an incorrect position, the system sets the block to its default position.

     NOTE:The Wyse 5070 Extended thin client supports up to six monitors. The Wyse 5470 Thin Client supports up to three simultaneous displays.
   • Select the Make this my main display check box to set the display as primary display or the main screen. After you set the display as the main screen, the display block is displayed in yellow, and the Make this my main display option is disabled for that display block. The Make this my main display option is now available for other display blocks.
     NOTE:The Make this my main display option is effective only in Span Mode and always disabled in Mirror Mode.
   • Select the Disable current monitor check box if you want to disable a display.

     If you want to enable the disabled display, from the Monitor drop-down list, select the disabled monitor, and clear the Disable current monitor check box. Click the Test button and then click OK.

   • From the Orientation drop-down list, select an option to rotate the display screen in different directions.
   • From the Resolution drop-down list, select a supported display resolution.
     NOTE:The default screen resolution on the Wyse 5470 Thin Client is 1366 x 768 or 1920 x 1080 depending on the configuration. The default screen resolution on the Wyse 5470 All-in-One Thin Client is 1920 x 1080.
     • In Mirror Mode, the resolution list is derived from the intersection of resolutions in all connected displays.
     • In Span Mode, select a display block and change its resolution.
   • From the Monitor drop-down list, select your preferred display.
3. Click Test.
   The new display settings are applied, and you can preview the modified display.
4. Click OK to confirm the new settings.
   Use the Identify option to know the display order number of the connected displays.
   Important Notes:

   • When connecting a monitor through Display Data Channel (DDC) with 800 x 600 and 640 x 480 resolution to the client, then 800 x 600 and 640 x 480 is listed on the resolution list of the display setup window.
   • If you change the USB-C Prioritization setting on the monitor, a black screen is displayed. You must reconnect the monitor to the device to restore the display.
   • ThinOS does not support the monitor HDR feature.
   • There is limitation for Wyse ThinOS 3040 GPU driver. The issue sometimes causes ThinOS to lose higher resolutions after waking up from sleep mode. As a result, lower resolutions cause user to view the wallpaper as zoomed in. To avoid this, change the time for entering sleep mode to 2-3 hours.
   • If you set a resolution that the monitor itself does not support, the monitor may display a black screen, or the display may not be correct. In this case, you must set a resolution that the monitor supports and reboot the device to recover.
   • If you connect monitors through the HDMI port, the monitors may not display anything after reboot. Turn on Fast Wakeup option on the monitors to avoid this issue.
   • The minimum resolution support for ThinOS 9 is 1024x768.
   • ThinOS 3040 does not support 3840x2160 resolution and above. If connected to a monitor that supports 3840x2160 or above, the client downgrades the resolution to 2560x1440 . The downgrade varies depending on the monitor.
