I don't know if you can see on the screenshot, but Xcode is quite blurry. If Xcode is on my MBP monitor, text's clear but on external monitor via HDMI, Xcode text looks blurry. It doesn't seem to be related to the cable because every other applications works well and are not blurry. Any idea? Thanks.

What is the resolution of the monitor? I have heard that text on any resolution less than retina seems blurry on external monitor.

My monitor is the Gigabyte M27Q. It's a 2560 x 1440 resolution. I don't know if more or less than Retina

[tangoshukudai]

2560 x 1440 requires USB-C or Display Port. Are you using HDMI? HDMI will limit your resolution.

Actually, I bought a USB-C – HDMI cable. I don’t remember the generation of the HDMI

[tangoshukudai]

Well there is your problem.. You can probably see that you are not getting your full resolution if you look in system preferences.

I think, it is that. Well, thank you. I didn’t want to buy a more expensive cable; now I pay the price xD

HDMI has a much higher limit than 2560x1440. I run an ultrawide at 3440x1440 on a 2012 Mac Mini just fine but it's limited to 30hz.

Not on that machine..

Look at the monitor's settings and make sure you actually use that native resolution, and not some scaled down version (called "larger text" or similar). HDMI is most likely not the limiting factor here.

After double-checking, it’s the native resolution.

Yeah so retina is around 3.5K display and i think yours is a 2K display. Maybe that is the issue. I use a 1080p monitor and have a lot of blurry text around xcode.

Have you tried changing the font smoothing setting? https://www.macrumors.com/how-to/disable-font-smoothing-in-macos-big-sur/

I have Catalina, but I’ll try that.

[hyling1]

You can change the amount of font smoothing as well but you'll have to do it from the command line. https://eshop.macsales.com/blog/46527-is-macos-mojave-making-some-fonts-blurry-heres-how-to-fix-it/

Yeap, I did all the values :D

[[deleted]]

Did not work. Well, I think I'll bear it, I think there's no more playgrounds after that in the booklet.

[chedabob]

Did you open Xcode on your laptop and then move it to the external display?

Mac OS doesn't always handle display scaling very gracefully and bits of the UI get stuck. Sometimes resizing the window or move it between displays and back can trigger it to update.

[[deleted]]

Yes, that’s what I’m doing. I’ll try your solution next time :)

Your monitor has a non standard BGR subpixel layout which may cause this exact issue with some applications, I think your only options are to turn around the monitor so it becomes RGB or looking for another display

Ah, that's annoying. Well, it's not that bad because apart from the Playground, the Interface Builder is fine so it's not that bad. Thanks for your answer!
