Using the On-Screen Display (OSD)
This section is applicable to Wyse 5470 All-in-One thin client.
Use the On-Screen Display (OSD) buttons on the right of the device to adjust the luminance of the backlight. Minimum is 1 and
maximum is 100.
● Press and hold the first button from the top to increase brightness.
● Press and hold the second button from the top to decrease brightness.
● Press the third button from the top to turn off or turn on the screen.
Port preferences on the Wyse 5470 Thin Client
● HDMI, DisplayPort over USB Type-C, and USB Type-C ports are prioritized over the VGA port.
● When a USB Type-C display is present, there is no display on the VGA port.
● If a VGA display is present, a third display that is connected is prioritized and the VGA display is turned off.
● If a VGA display is not present, a third display that is connected is ignored, or a blank screen is displayed on the third screen.
Display limitation on Dell WD19 docking station
On Wyse 5470 Thin Client, ThinOS supports the following monitor connections using a Dell WD19 docking station:
● One Quad HD display at 30 Hz
● Two Full HD displays at 60 Hz
If two displays with resolutions greater than 1920 x 1080 are connected simultaneously, there can be the following behaviors:
● Random resolutions—You must change the resolutions to 1920 x 1080 or lower to make both displays work. Also, disconnect
and reconnect the docking station to correct the resolution, if required.
● Second monitor is disabled—You must first enable the monitor in Display Setup, and then change the resolutions to 1920
x 1080 or lower to make both displays work. Also, disconnect and reconnect the docking station to correct the resolution, if
required.
Vertical Synchronization
Vertical Synchronization or V-Sync enables the ThinOS client to synchronize the frame rate of a video with the monitor refresh
rate to avoid screen tearing. Screen tearing occurs when the graphic processor delivers display frames more than your monitor
can process. As a result, the image appears to be cut in half. Enabling VSync synchronizes the output video of the graphics card
to the refresh rate of the monitor. V-Sync is enabled by default on ThinOS. V-Sync cannot be disabled in ThinOS 9.x.
Configure the external touch screen settings
Dell Technologies recommends that you use the default resolution while using touch screen. If you use a custom resolution, the
touch screen does not calibrate accurately. By default, the touch monitor Dell P2418HT is supported. To use other touch screen
monitors, you must configure the Bind Touch and Monitor settings either using Admin Policy Tool or Wyse Management Suite.
Steps
1. Connect the touch monitor to the ThinOS client.
2. Go to System Information > Event Log and locate the information for the touch monitor. For example, screen1 [0xac10,
0x4114], Touchscreen [0x1fd2, 0x6103].
3. Open the Admin Policy Tool on the ThinOS client or go to the ThinOS 9.x policy settings on Wyse Management Suite.
4. On the Advanced tab, expand Peripheral Management and click Touch.
5. In the Bind Touch and Monitor section, click Add Row.
6. Specify the screen device ID. For example, ac104114.
7. Specify the touch device ID. For example, 1fd26103.
8. Click Save & Publish.
NOTE:
Dell Technologies recommends that you use a direct DisplayPort, an HDMI, or a VGA cable for connecting
the touch monitor and the thin client. If you are using a convertor, the touch function may not work by default.
