¹Dell recommends that you configure first two 4K displays on the main board (DP1~DP3), and the third 4K display on AMD GPU card.

²Dell recommends that you configure a maximum of four displays with 4K resolution and the remaining displays with non-4K resolution on DisplayPort 3 and DisplayPort 6 for optimized stability and performance. However, based on the maximum technical capability of Wyse 5070 Extended thin client, ThinOS supports a maximum of six 4K displays.

  • NOTE: Best practice—To achieve maximum 4K display output, Dell recommends setting up 1080p on the DisplayPort 3, with rest of the monitors in 4K resolution to optimize performance.

Monitor priority—The following order defines the monitor priority set on ThinOS for Wyse 5070 Extended thin client:
  • DP1 > DP2 > DP3 > mDP4 > mDP5 > DP6
  • DP1 > USB Type-C > DP3 > mDP4 > mDP5 > DP6
  • DP1 > DP2 > VGA > mDP4 > mDP5 > DP6
  • DP1 > USB Type-C > VGA > mDP4 > mDP5 > DP6
  • NOTE:Monitor cable hot plug —Screen layout settings are changed based on supported monitor resolution and the port to which the monitor is plugged in.
  • NOTE: Earlier in ThinOS zero theme, the Display Setup window was aligned with left-hand setting panel. In current scenario, the Display Setup window is positioned to center of the screen regardless of Classic/Zero mode. This enhancement is made to easily configure the display setup along with the confirmation window.

INI parameters—The INI parameters for display in Wyse 5070 thin client are from ThinOS 8.5 legacy INI. The INI parameter supports only two monitors, that is, the INI settings can only impact the first two screens. If you add the third screen, it follows the display settings defined for the second screen. There are few settings that are not applicable for Wyse 5070 thin client with ThinOS. For more information, see INI parameters. Further solution on INI settings for Wyse 5070 thin client with ThinOS is provided post RTS.
