The NCS matrix cannot show on monitor fully.
NCS Matrix supports 4:3 and 16:9 resolution ratios. If the Matrix layout resolution ratio is different from monitor, this issue will occur.
1. Replace the suitable resolution ratio monitor as NCS Matrix layout.
2. If you don’t have another monitor, please uncheck the selection “fix the Matrix grid ratio” of NCS client Matrix configuration then NCS Matrix will fill in the monitor no matter what is the resolution ratio of it.
