Question regarding Epson Projector Lumens calculation

Community members, @Jacques Booysen has asked for help in calculating lumens. We'd appreciate your help! "Hi All, In South Africa we work with average 500 lux indoors, I have a 200" screen and would like to find the appropriate projector lumens for it. I'm looking at an Epson EB-PU2216B of 16000 lumens and contrast ratio of over 2500000:1 the calculations doesn't make sense to me although I converted to metric. I'm getting an answer of 10 000000 to the power of 10. please help." @Donato II Oliman , @Huan Phung Thien , @Luis Valenzuela , @Steve James ...others...can you offer assistance here? Thanks!

Raspberry Audio

I have Raspberry Pi4 for thin client testing and very happy with it. I didn't check the audio and maybe I will go ahead and do that.  Raspberry is pretty helpful as rule (though I work with higher ups).  I might check with them on best support options they recommend as well as taking a look myself. I would simplify things first and see if you can make it work in a more basic configuration.
