I own MacBook Air (13-inch, Early 2015), I bought a Samsung C24F396FHU 24 inch monitor to use a bigger screen and prevent headache. But now that I connected the laptop to the monitor using a Thunderbolt to HDMI cable , the font is not smooth at all and the text is not as readable as it used to be on the original display.
The cable:
Is the issue due to using non-Apple product (Samsung monitor)?
The monitor is FHD 1920x1080 and there's not much settings to adjust the resolution (picture below).
