If you’ve just purchased an Apple Mac Mini M1, you may have found the display on your screen to be abysmal. Indeed, if your screen is not Retina, the display rendering is runny / blurry.
It sucks to pay such an expensive computer to screw up your eyes because Apple does not allow activation of HiDPI when connecting an external display to the Mac Mini.
How do you know if it’s allowed or not with your screen?
Well if the quality is good and you see these options in the display settings, it’s OK.
If the quality is poor and these options don’t appear, that’s no good.
So what to do?
There is a tool called Better Dummy which, once installed on your Mac Mini, allows you to simulate a screen in the resolution of your choice. As you can see in the capture below, we can simulate 4K, 5K, 6K screens and that’s what interests us.
This application is really useful for all those who are not satisfied with the default HiDPI resolutions offered by macOS or for those who have a rotten screen and who are not satisfied with the screen captures they take.
Basically, thanks to this free software, you will have your normal screen + this virtual “Dummy” screen that you cannot see yet, because it is virtual.
Then, it is by making this virtual screen your main screen (Main) and by activating the mirroring of this virtual screen on your main screen that you will be able to take advantage of it.
There you go, problem solved. Mac OS will think you have a Retina display and it will offer you the right options and a quality display!
Your eyes can thank me 🙂
