Blurry Fuzzy Text on external monitor with MacBook Air 2020

Texts become fuzzy on external monitor connected with MacBook Air 2020 M1 chip (MacOS Big Sur).

Font smoothing disabled by terminal command didn't help.

Changing adapter and HDMI cables didn't work. Alternating options in settings are in vain.

But any window notebook !! give me a smooth text with same monitor and same cable. (Even a 300$ window notebook is working)

I found many people have same problems, like me. And no solution until now.

The only hope is that Apple engineers could find a definite answer soon or we wish Apple hire more expert ones.

please help me if you found any solution.
