PowerFlarm displays and polaroid sunglasses

Hi Gang
This posting is only relevant to people flying with polaroid sunglasses as I have done for over 20 years.
Firstly the display of the portable unit comes with a polarizer that requires the display being used in the landscape mode. Rotate the unit/display by 90 degrees and the display becomes invisible. If you don't use polarized sunglasses this rotational artifact is not visible.
Now in contrast the Butterfly display which many people will use with the brick is polarized to be used in the portrait mode with polarized sunglasses. Why the difference? Someone was not paying attention when they ordered the LCD displays.
The solution for me since I did not have the space in the instrument panel to rotate the Butterfly display 90 degrees was to mount the Butterfly displays (2 seater) using articulated arms so that I could manually rotate the display to what suited me. These arms are sold by Cumulus Soaring.
Bottom line to this posting is if you don't use polarized sunglasses you can mount the displays either in landscape or portrait orientations. If you fly with polarized sunglasses and are installing a PowerFlarm unit be aware orientation may be a concern as it was for me.
