This is my little solution for LG 29WK600 Wish I have had this under my vision before trying for days to fix SwitchResX. I had another adapter (hdmi/vga to displayport), connected my monitor to it, and the very same custom resolutions just worked! I tried changing settings (custom resolutions) at SwitchResX, and always got back a 'Not activated - invalid?' message back.Īfter days, I read some comment, regarding trying to connect directly to thunderbolt/displayport. In my case, my LG 29UM68-P worked connected to a j5 create hub, but one day it just stopped working.

Use suggestion upon starting point: in fact, use the parameters, as suggested, and just duplicate the custom resolution and change the vertical Hz valueĪnd, the most important thing is: have another video adapter available to test.

Have a backup of your previously working settings, or at least remember where you took them from.

This is very important! in case anyone is stuck upon having a working version of your widescreen, and suddenly it stopped working:

Close SwitchResX and save when prompted.Īfter following these steps, you should be able to adjust the resolution of your external monitor through the 'Display' window in System Preferences.Adjust the settings to match the appropriate PNG provided in this gist.Add a new custom resolution be clicking the + symbol at the bottom of the window.After launching SwitchResX, select the external monitor from the list on the left.Once in recovery mode, open a terminal window.Boot into the recovery partition by pressing CMD + R when starting up your Mac.If you are running OSX 10.11 or higher, SIP must be disabled. #Disabling System Integrity Protection (SIP)

(last bug I noticed: if the monitor reports that it also supports 1280x1024 60Hz, as standard or established timing in the EDID, even if it is a 4K native monitor, then HiDPI will not enable.#SwitchResX Settings for LG 21:9 UltraWide.

This has given some clever developers to develop software solutions to add virtual 4K monitors to mirror your screen onto

This again proves the limitation is intentional, since the video driver is then completely capable of handing HiDPI resolutions. on any other monitor, whenever it mirrors an other monitor where HiDPI is available (example: a 2K screen mirroring the internal Apple Silicon MacBook screen).Some 4K Dongle are 4K capable, but not 4K native The basically means the monitor must show 4K as its native resolution. Note that from Apple words: 'the mere presence of a 4k timing does not mean it’s a 4k display and because of this we don’t expose HiDPI modes.'. on 4K monitors showing a 4K as the native resolution.on internal MacBook screens, because the pixel density is higher than 160.This proved to be intentional, not a hardware limitation, and certainly not a bug that you should wait to be solved.įrom the best of my knowledge, HiDPI resolutions were previously only enabled on Apple Silicon: Reporting this as a bug or as feedback to Apple resulted in them answering it's acting as intended (see radar FB8715490 for those who can access this).

Beta 7 removed this possibility from Monitors that aren't 4K, and then beta 9 removed it from monitors that aren't 4K Native.

It was intentional, as it worked on the DTK (the Mac that was used as prototype for Apple Silicon Macs) up to BigSur Beta version (ß6) in September 2020. This matches the behaviour of the 4K displays now.įor history: before macOS 12.4 Monterey, HiDPI was explicitly reserved to specific monitors.Īpple intentionally disabled all HiDPI capabilities for all monitors that aren't 4K native, or don't have a pixel density of at least 160dpi (on the horizontal size as reported by the monitor). You cannot get a 2840x2160 HiDPI resolution in this case (which would be useless anyway). If your Mac uses a 2560x1440 monitor, you'll be able to get a 2560x1440 HiDPI resolution (by creating a 5120x2880 resolution), or anything lower. HiDPI resolutions get again enabled, up to the native resolution (ie. It seems to now be in par on 4K monitors or in non-4K monitors. Beginning with macOS 12.4, the behaviour changed on Apple Silicon Macs.
