Acer XZ270X (curved) depth of field obscure

Beci_xz270x

Hi there community! 
I bought a new monitor. The 2-year-"old" 27 inch IPS flat screen, instead of a curved one, with VA panel...(i think this is the most accurate information i changed to what) So...I'm very disappointed. Except at 240Hz, I can't say anything positive about the monitor.. I just can't find a setting that can only approach the color depth and sharpness of the old monitor. I tried to set it in the monitor menu. I tried the Acer monitor driver settings, and then the AMD software as well. Nope. The image is always a bit blurry. E.g. games simply lack image depth of field, blur the center of the image, or distant things, and blur.
-I tried without drivers. I deleted everything, reinstalled it, step by step, it hasn't changed.
-I tried with the factory hdmi cable and then with a new hdmi 2.0 cable, 1.2 display/HDMI port and 1.4 display port/display port cables.
- My VGA is a Nitro+RX5700XT (latest amd driver...)
-approx. I look from 70 cm in the middle. The monitor is level.

The store (Acer Shop) said this is the difference between VA panel and IPS, this blur is the price of 240 Hz ?? !!!

So let me sell or look for another type, maybe a brand .. (I have 4 acer monitors in use in home)

OR there’s any simple solution to it (obviously not take it back to the store or calibrate it because they ask for a lot of money and it’s also far from where I live)

Thank You.
