HD320U - 4K display problem.

[songpiapia]

My display is a 4K display which not have HiDPI resolution.
After I created a 16:10 new dummy ，I have HiDPI option, but it looks like in low resolution without HiDPI.
How to solve this problem? (M1 Mac mini)

Hi @songpiapia

can you please make a screenshot of what you see under About This Mac > System Report > Graphics/Displays with and without running BetterDummy?

Thanks!

So the 1920x1080 here is low res?

What if you create a 16:9 dummy, what settings do you see when press OPTION+Scaled under the dummy?

[songpiapia]

Yes, 1920*1080 here is low resolution

If I create a 16:9 ,it still looks in low resolution.

Well, to be honest I don't have any idea what is wrong actually. What I see is that your screnshot is HiDPI so on BetterDummy side things look well. It is not clear to me why does it translate to a low-res screen somehow on the display. I'd need a display like this to experiment probably to understand the problem better. :( I am sorry.

I am unfamiliar with the display model but I added it to the title - maybe somebody with a similar display can share some insight.

Thank you all the same!
