I agree with Jerry. As the Guide says, you have to compromise. Get the sub/center channel splice as smooth as possible and then check the L&R, making adjustments to each until they are acceptable....

Of course it isn't the same as all channel stereo. But it's a useful analogy. With all channel stereo, two channels are copied identically to various other speaker sets. With Auro, the 'base'...

Lens shift just moves the entire image sideways, or up and down. It won't change the aspect ratio.

Are you sure your screen is the exact right 16:9 proportions there?

Why not just leave it on all the time?

One potential problem with turning it on with amps is 'switch on thump' through your speakers, which can, apparently, be loud with miniDSP units.

The problem is that you are working in three planes all at the same time, and adjusting any one affects the other. The one thing you definitely should avoid is using keystone because that...

Absolutely. Buying AV gear isn't an "investment". It's about enjoying what is available, when it is available, IMO. I could have waited for DTS:X before I bought my Atmos unit. And then I would have...

It serves the purpose of creating separation between the listener level speakers and the overhead speakers.

Remarkable achievement. I have never measured the temperature mine reaches but if you put your hand on the heatsinks, you'll burn yourself.
