Blurry texts on an external monitor connected to the latest (2020) MacBook pro

Hello,

I got this LG monitor (LG 32 in. QHD Gaming Monitor with FreeSync) to have a bigger screen for reading, not for gaming. The fonts on an external monitor are not as clear or crispy as through my MacBook Pro. I changed the resolution scale to 2560x1440 and refresh rate to 75 Hertz. However, it is still not up to my satisfaction. Both are connected through HDMI.

I tried on one of Windows laptops and changed the settings like above. The display was very clear and crispy, which I liked.

I don't know why Mac cannot have the same result. Any other idea?
