Issues with two monitor setup
You may need to optimize the display settings on the XT Series endpoints.
Solution
• Check that the XT Series HD1 and HD2 output are connected to the video source plug on the
monitor. If the monitor model has more than one selectable HD video source, use the same
one on both.
• Use HD cables of the same model and length and verify that the connectors are not
damaged.
• Access the general monitor settings. From the XT Series web interface, select Administrator
settings > I/O connections > Monitor > General. From the endpoint's main menu, select
Configure > Advanced > I/O connections > Monitor > General. Ensure that the default
values are set:
- Numbers of Monitors: Auto
- Resolution HD1: Auto
- Resolution HD2: Auto
• In the General screen, check that the detected resolutions of both monitors are identical and
corresponding to the expected ones.
• Access the monitor settings. From the XT Series web interface, select Administrator
settings > I/O connections > Monitor > Graphic Adjustments. From the endpoint's main
menu, select Configure > Advanced > I/O connections > Monitor > Graphic
Adjustments. Ensure that the Adjustment Mode is set to Menu, Presentation and all other
fields are either set to 0 or are set to identical values.
This is not applicable if using a 4K monitor. It is supported only for HD1 on the Avaya XT7000
Series.
• Check the settings on the third party monitor. These settings vary depending on the monitor
vendor and model. These are the most relevant things to check:
- The monitor vendor and model should be identical.
- The graphic settings, such as backlighting, contrast, sharpness, and color should be
identical and ideally they should be the default values.
- The movie or cinema mode should be used and not the gaming mode.
- Cropping or resizing of the content on the monitors should be disabled.
- Any dynamic gain or smart management of the image should be disabled.
