Can apple pls, pls, pls, tell me when can you fix the problem of m1 chip not support hidpi on external monitors? Or do you even aware of this problem?

I've been using mac for a long time, and i was able to connect to a external monitor with high resolution and good size fonts using 3rd party softwares, like one-key-hidpi or rdm.

However, now with your latest m1 chip, none of them work anymore. Now i can either use a high resolution with ant size fonts, or i can choose big font size with blurry displays resolution, which is very annoying.

so, are we going to fix this issue? or is there any workaround for this?

Had the same problem with scaling. Got the 4K portable monitor UPERFECT https://www.amazon.com/Touchscreen-UPERFECT-Automatic-3840x2160-Integrated/dp/B083ZFG1PF?ref_=ast_sto_dp

Connect it to old MacBook Pro 2015 via HDMI and everything is ok, I got a scaling options.

Connect to M1 MacBook Air via USB-C and everything goes bad. The "Default for display" resolution is incorrect (on old macbook everything is ok), and i can't set scale for display. If i choose 1080p, then the resolution goes 1080p and text go very blurry and uncomfortable to working with. I updated macOS to latest available version 11.4 and the problem still remain. Does anybody tries on beta Monterey?

Also i tried connect the display to M1 macbook through HDMI via hub, but everything the same.

I found a solution for QuadHD monitor and M1 Mac and posted on Macrumors forum.

Search "Solution. QuadHD monitor with HiDPI and Mac Mini M1" in Google.

Briefly, you need to buy 4K HDMI EDID emulator (8 USD), USB-C to DisplayPort or HDMI converter (8-12 USD) and enable Mirror Displays option in macOS. Now you'll see scaled HiDPI resolutions.

I'm quite upset about this actually. Just bought a M1 mini and planned on using my UPerfect (strange brand name, great screen) 4k portable monitor with it. I was excited since the HiDPi worked fine with the 2013 MBP I'm replacing. Then I connected it to the mini and... no options as others have reported. Surely someone from Apple has heard about this and if they are reading this, I regret buying the M1 mini, I should have bought an intel version... How can you say the M1 is superior when it cannot even be used to write an email? Apple used to be the reference in how UI is easy on the eye. This is the exact opposite. I guess I have to waste money on a 1080p monitor now... forget about 4k. Thanks for the half-baked product Apple...

This problem still exists! Finally got my M1 Mac last week, two 1080p monitors that worked with my old Lenovo Thinkpad, trying to connect to them via dock gives a weird blurry second monitor and turns off the first one. Completely devastating, to have such an expensive computer fail at such a simple task, a task the old 2015 Macbook Pro could still do.

And after three months of an open case on Apple Support, I called them just to hear that I should buy another monitor. To fix something that is clearly a software issue.

It's hard to work with Apple devices that way...

Same issue here. I'm very disappointed with apple. I was happy with my QHD display and any other machine other than m1. are there any developers to solve this kind of showstopper issue right now? at least apple shoud answer and let us know the plan! what a shame. it's been a year. don't waste your time to add minor cookie functions. FIX THIS ISSUE FIRST!!!

I got the same problem as you guys and I arrived at the following conclusion: if Apple won't fix this with macOS Monterey I will sell my M1 Mac and switch back to PC. Not liking Windows but I just had enough!

** +1** LG 27UL850 4K Monitor. There are no problems when connecting USB-C. When connected via the hub and HDMI or DP - there is no resolution of 2560x1440 (HIDPI). I'm sad with the new Air M1.

I experience the same problems since November 2020. MacOS sucks at HiDPI integration and scaling for external displays. In windows 10 or Linux my 24” QHD displays are razor sharp! This is 8 year old hardware and the new QHD monitors look amazing.. on Mac Mini M1 it just sucks.. blurry/fuzzy. I get headaches from it..

I sincerely hope apple will fix this mess with external displays. There is no reason not to enable. HiDPI on QHD monitors, it is not 2005 anymore and the GPU’s are more than capable without any performance hit.

I also tried the 4K Edid emulator solution as discussed on macrumors; this unfortunately is not. A full solution
