Flatscreen between speakers


Has anyone found a solution to cancel or at least improve the acoustic glare caused by a flatscreen tv on the wall behind the speakers? I don’t have a dedicated room and have to share the room with my home theater setup. I have thought of using an appropriate curtain and treat the tv as if it was a window. I am also considering light 3D printed panels that I can temporarily hung when listening to music and take down when watching TV with the wife. 
I tried hanging a couple of thick towels on it to see if there would be any improvement and the answer is yes. The center image is more solid and a little deeper. Nothing drastic but if I could squeeze anything positive, why not. Please let me know if you have confronted this issue in the past and whether you were able to solve it. Thanks.

A 100% wooven wool rug is the best you can do. I got one exactly the side of my screen handmade from a indigenous lady on a beach in Belize. I stapled the top of it on a 1/2" × 1" wooden stick and it self holds perfectly over the screen with the stick in the back top of the TV. Easy to put on and take off. You can see it in my house of stereo system.

I've been experimenting as well.  One approach I'm looking at is to mount the TV on the wall, build a frame or box around the screen and then, using barn door sliding brackets to open and close doors covered either with acoustic absorbation or diffusion panels.  I think it will not only look better, but would be better acoustically than heavy curtin material.
