Pls fix m1 chip issues with external monitor hidpi

It's 28 May 2022 and the problem is still not fixed :(

i think this problem is not software problem. Because if it was, apple would did fixed. i think this is hardware or chip problem. Yes i know some 3. Party application fix this. But with 60 hz. i will buy new display. :(

Please fix the issue. Also for higher refresh rate (> 60Hz) monitor. I'm using a 240Hz for work, little bit extreme, but have some empathy yo.

This fix has to be the main highlight of the WWDC 2022. 😂

2022 - is a year, when FreeType on Linux renders fonts by and order of magnitude better than Mac. Back to basics guys ! =)

So guys who tested the new Ventura?

What worked for me on my Mac Studio (Should be similar for other M1/M2 devices):

Boot your computer on Safe Mode. Now go to Displays under System Settings (Mac OS version below 13.0, it's System Preferences). Enable Scaled under Resolution and select Show all resolutions. You should now see many more HiDPI options. Choose the one you like. Afterwards, just restart your computer. That's it!

How to enable HiDPI on M1 based Macs on any resolution

I have some interesting news: I found a solution to enable HiDPI on M1 based Macs on any resolution, even on 1080p screens, without the need to use mirroring or other workarounds.

Here is an example of HiDPI running on a Dell U2415 monitor that only supports a maximum resolution of 1920x1200:

What you need to do is to edit the com.apple.windowserver.displays.plist file located in

/Library/Preferences/com.apple.windowserver.displays.plist

and change the key <key>Scale</key> to have a value of 2.

This is an example of how the section in the displays plist file should look like after the change:

					<key>CurrentInfo</key>
					<dict>
						<key>Depth</key>
						<integer>8</integer>
						<key>High</key>
						<real>1200</real>
						<key>Hz</key>
						<real>60</real>
						<key>IsLink</key>
						<false/>
						<key>OriginX</key>
						<real>0.0</real>
						<key>OriginY</key>
						<real>0.0</real>
						<key>Rotation</key>
						<integer>0</integer>
						<key>Scale</key>
						<real>2</real>
						<key>Wide</key>
						<real>1920</real>
					</dict>

Make sure that you change only the Scale key for the monitor that you need, and nothing else.

You can follow the step-by-step video tutorial on how to make the changes in the displays plist file here:

After that, restart your Mac and you should get HiDPI and noticeably more crisp and anti-aliased text, and the high resolution macOS icons.

An easy way to confirm that the HiDPI changes work is by looking at the Safari icon on the dock. If the HiDPI version of the icon is enabled, it will have a lot more sections in the compass than the low resolution icon. It should look something like this:

Please note that while this might make the image look better even on 1080p screens, they will still be running at 1080p resolution, so the change might not be as drastic as running on a higher resolution screen.

If you have any questions about the procedure, please feel free to contact me or comment below.

This is absolutely absurd – Apple, we need basic external monitor support! When do you plan on supporting your customers?

Bought M1 Pro was super thrilled about it and it's a great device. Connected it to my daily driver 1440p MSI monitor and after a whole weekend of trying to make it work returned the MBP. Super sad that this OS can't get basic stuff like this right. And here we are bashing Windows that its bloated and so on ... well at least you can run it with almost any setup. Same goes for linux

It's working since a few weeks, that you can read above 1 month ago, posted by @imagnity:

Do I understand it correctly? If I want crisp text on 34 ultrawide monitor with 3440 x 1440 resolution the only way is to return my new Macbook Pro 16 M1 Pro and go with Windows instead? Or ditch my monitor and buy their Studio Display with non detachable cable or that plastic LG Ultrafine 5k equivalent with that ugly big top bezel ? Oh my....

It seems that Apple solved this problem in macOS 13 Ventura. I checked Beta 6 today and it offers several HiDPI resolutions for my external display Dell 24" QuadHD (2560x1440) connected to Mac mini M1. No need to use BetterDummy utility or dummy 4K HDMI emulator.

Just wondering if there's been an update to this, we have 2 4k monitors, I'm wanting to use 2560x1400 but not in low resolution. We are connecting via Targus dual 4k support hub to USB C on the M1 Max Macbook Pro

I have an older 2019 Macbook Pro that I had plugged into my LG UltraWide 49" with a resolution of 5120x1444 and was running Ventura beta 6, I upgraded to beta 7 yesterday and now my display doesn't work anymore! both displays are completely garbled with no chance of recognizing anything!

It's same issue at M1 Pro with Samsung S32B80P

DP cable is work (3840 x 2160)

Usb-c PD is wrong resolution (800x600)

in other hand, using Intel chip MacBook Pro with Samsung S32B80P usb-c PD is fine.
