Please help me with setup tips

Please comment on my setup

I completed my setup and did my best while managing the budget and quality as a first time HT setup creator. I find my sound OK but I am not sure if i am extracting the best possible from my setup. Some key settings that I use on my Denon are

dynamic volume on, LFE level to 0 (it goes only 0 and below which is sth I don’t really understand), dynamic compression OFF, and multi eq to reference and cinema EQ to ON.

I also use the DTX neural upmix for music.

Another aspect which I am iffy about is my projector (epson 3800) despite several attempts to sharpen focus I still find the projector blurry esp. for text. Appreciate any suggestions on how I could improve my setup.
