Flat screen between speakers, again.

I’ve recently researched this subject. It seems a lot of people with elaborate solutions eventually end up leaving it off permanently.

I just replaced my TV and had the wall bare for a few days. I did notice a slight improvement in soundstage stage depth. I’ve decided to try treating the rest of my room first and only then revisiting the TV situation. I did get a mic and run some baseline sweeps for frequency response and reverberation time.

Diffusion is usually heavier, especially a skyline type that is deep enough to have a wide effective frequency range. You might need a counterweight system or risk damaging your screen. Full coverage of the screen may not be necessary either. I may experiment with some 2’x4’ panels and listen. It should be easy to hang them even with 6” spacers so they clear the TV. Depending on your room layout a set of heavy movie theater type curtains might be an option.

I’m not yet convinced it’s necessary in all situations. Only you’ll know if the juice is worth the squeeze.

And I forgot the obvious one. All things considered it might be best to treat the room first, and then get a motorized TV lift cabinet. 

More of a visual thing.  Close your eyes when listening.  Hearing is improved without visual interference.

@tony1954  Try a test with a sheet of Owens Corning 703 fiberglass board and see what you think.

Perhaps a 5 sided box with absorption on one side and diffusion on the other side that could slip over the tv might work? Just be mindful of the cabling.
