I have the JimTab M18 Pro 1080 Projector.

It has one Speaker and I go into the Audio Setting and it gives me a list to pick from.

120 Hz 45
200 Hz 50
1.2 kHz 50
3 kHz 45

I know if I pick 3 kHz this is the FREQ. Range it will try to out put.

What is the 45 for?

 

3 kHz 45 means the equalizer’s 3 kHz band is set to level 45/100, shaping how much of that range comes out of the speaker.
It does not mean the speaker only outputs 3 kHz.The projector still plays the full audio, just with some emphasis or de-emphasis at those ranges.

 

Thank you for getting back to me.

I do have one other Setting I do not understand.

On the Top of the JimTab M18 Projector is a Keystone Wheel.

If I turn the Wheel just the Bottom of the Image gets skinny or not.

Without a Wheel to make the Top of the Image skinny or not how do you use it to make a square Image?

You should be able use that wheel to get a square image whether the projector is above or below the central axis of the screen.
Does it not do that, or are you just asking a theoretical question?
