When we turned on the display after installation, parts of the screen are in the wrong position ?

This will indicate that the display cabinets have NOT been installed in the order as shipped from
Aurora. Check the Aurora documentation to ascertain the correct layout and position. This can be resolved by loading up novastar software and re sending the display configuration to the screen.
FIRST, be sure to save the existing config files as a matter of redundancy. (refer to Aurora Quick Guide or contact Westan support if you arequire assistance)
Ensure you selected “send to HW” first and check that the display is now correct prior to saving screen configuration permanently in receiver card memory.
