LondonCalling, what the hell is going on over there? Is all your stuff blown up or does it sound pristine like the Sirens who seduced Odysseus and his ragged men?

Thanks for the suggestions. I did the factory reset and re-ran the AutuEQ and found that its not that accurate on distances< the left and right should have been equal distant but they werent. The sub was twice the distance away. So tomorrow I will manually set up. the distances with a tape measure and the levels with a decibel meter.
I have tried what Mojo suggested about listening to familiar music and found that the higher frequencies like a violin are not as bright as they should be. I think the screen is muffling them a bit. I will also play with the eq in the above 160 range to try and remove the muffling. If I can figure out the post a picture feature I will show the Onkyos Eq.

The sub set at twice the physical distance may be OK. There may be delay through the sub.
I don't have experience with speakers behind screens so I can't help with that other than to suggest you diddle with treble or EQ.

Manual is better, but hard to set sub distance without measuring gear. Where you put the measurement mic and the seating fabric will skew the result in auto EQ. Use a tripod and keep the mic away from the seating back. Ensure the mic has line of sight to each speaker. If the seating is leather or pleather, place a towel or blanket over it near the mic so the treble isnt reduced as much by the auto EQ. The screen shouldnt roll off that much treble. Maybe 2db above 8khz. Slightly boost it but try the other steps first. Boosting treble in a lively room is usually a bad outcome. When you get it right you will join the 1% club. Congrats on the AT screen setup.

Sorry for the delay in posting. Last night my youngest daughter needed the room to host a class on zoom and then after that the middle daughter needed to practice her masters thesis defence before presenting today. Heard back today that she passed and her thesis is being presented to the dean for top science thesis for the year at the university. Thus no progress. Tonight when I got home and I have a neck strain and tinnitus in my right ear. Can't trust my ears tonight. Luckily today I heard that my Saturday job has been cancelled and I have all day to tweak. In the mean time I have set the distances manually and used my RS sound level meter to equal the levels. The LR are set to +1.5, Centre 0, surrounds at 0 but the sub is at +6 everything is producing 71 dBA

Well...OK. We like to see a little more initiative around here when it comes to audio but given your circumstances, we'll let this one slide. Glad you know your priorities between work and audio.

Hmmm ... master thesis vs. proper receiver calibration ... close priority call, but okay we'll give you that one. Seriously, congratulations to your daughter (and you by extension) for the masters! Nominated for top science thesis of the year is very impressive. What's her degree in? I didn't know schools had you present for a masters; I just had to write a paper.

I had to present for my Bachelor's back in '88. My son had to present for his Bachelor's last year. He has to present for his Master's also. Maybe it's different in Canada vs. the US.

My daughter is in Earth Sciences- Water (Hydrogeology I think) . We think she made a smart choice with all this talk of impending fresh water shortages.
I reset the levels and distances manually but was still having problems with booming base ( the sub channel was set to -15) and it was still too loud and pounding. I retried the auto set up using Trevor's suggestion of a towel over the leather couch. What a difference! The treble is there and the booming base is gone. The distances came in accurately. The dialogue is now coming out of the screen smoothly and clear, sucess!
