You need to tell us how you're connecting the monitor to the MacBook Pro. Which port are you using from your MacBook Pro and input port on the monitor. And which type cable and or adapter?

People for some reason do seem to forget one big thing about this. APPLE has removed AAA sub-pixel font smoothing from Mojave and Up. The blur you see is because of that. So blame Apple for removing when Windows / Linux has it and it works fine.

Do you mind explaining this? So I know what not to purchase in the future. Does external screens need to have the same resolution as the computer? Or are all external screens bad nowadays?

Any 4K monitor will work fine. MacOS will treat these as retina displays just like the built-in display.

Is it a VA panel? I had bad experiences with every VA monitor

And there is no possible way to fix this?

Newer 4k displays from all sorts of vendors work well (and even QHD 2650 x 1440 ones too...).

Two things to try:

Test with an Apple USB-C Digital AV multiport adapter connected via HDMI and see if the results are any better than USB-C cable that came with your display.

Only other thing that may be helpful is changing the weight of the fonts... (see the bottom part of this article that describes adjusting font smoothing settings).

it could be tied to the color configuration as was the case with me. This is what I did for a Dell monitor. Once I fixed this, my text was crisp and smooth.

Maybe search the web for ‘Samsung monitor RGB Mac’ Or something like that.

Include a screenshot of the displays preference pane showing the resolution etc the screen is running at

also maybe include a cell phone picture of the problem

otherwise we are all just guessing...
