Hi,

asking for your help. Having the M511 projector, with latest updates. I have 2 issues:

  1. When entering to the menu I cannot select/midify all the options (eg. Brightness, contrast, colors, adjustments, etc), about 1/3 of the options are inactive. How to get them back to do my custom setup?
  2. My bigger problem is that I do not know how to adjust my screen on the wall to have a regular rectangle instead of a distorsioned one. Under menu I have the Auto keystone option, which is failing, screen is 40 cms higher on the right than on the left. If I seitch to manual I have only 1 keystone option to play with but that is rotating around the wrong axis, no other keystone (eg. Horizontal and vertical). How to set up this accordingly?

Thank you for the great advices!

Regards
