Does this mean custom scaled resolutions were created by SwitchResX? The webpage for creating scaled resolutions may use different hex data than SwitchResX. Scaled resolution includes the width and height and may optionally include flags:
Post the override file created by SwitchResX.Code:
kScaleInstallAlways = 0x00000001, // skips all the various checks and always installs kScaleInstallNoStretch = 0x00000002, // disables the install of a stretched version if the aspect is different kScaleInstallNoResTransform = 0x00000004, // install resolution untransformed kScaleInstallMirrorDeps = 0x00000008 // install resolution on mirror dependents of this display
The HiDPI modes are listed in SwitchResX but when you select them, they give a black screen? Post a screenshot of the current resolutions list.
macOS has a minimum height and width for scaled resolutions (I think minimum height used to be 600 but now it's 500? check various non HiDPI resolutions) so it won't accept HiDPI modes that have a height less than 1000.
Seems like it might be a bug with Apple's drivers. What version of macOS are you running?
Your display has a blank custom display name. You should enter something or unselect the "Use custom display name".
You only show the 100 Hz version of the scaled modes. There should be corresponding HiDPI modes for 50 Hz and 60 Hz (for example, 2580 x 1080 HiDPI 50Hz, 60Hz, 100Hz).
Did the 1720 x 720 HiDPI mode also not work?
For the 2580 x 1080 HiDPI mode, what if you create a different ratio by adding 8 pixels to the vertical only, will the HiDPI mode work? Keep repeatedly adding 8 pixels to the vertical until it does work. Then repeat the test starting at 2160 and subtracting 8 pixels until it works. I want to know how different from 21.5:9 the aspect ratio needs to be before it can work.
Attached switchresx plist (originally had no file ext on the end, had to add .txt to allow the upload) and also my plist generated with https://comsysto.github.io/Display-...or-with-HiDPI-Support-For-Scaled-Resolutions/
I do remember switchresx adding things to my generated plist, however I deleted this file from the appropriate displayproductID folder inside the override folder, as I could see switchresx created its own plist for the monitor under 'DisplayYearManufacture....'
If you could make me a custom switchresx plist that has 5 or 6 resolutions around the scaled 4816x2018 range I would appreciate that.
Attached screenshot of current resolutions and 2 scaled resolutions which I added with +2 in vertical pixels. (4816x2018, 4472x1874). When I select the HiDPI res's at 21:9 that are meant to work (no +2 in vertical) nothing happens, no black screen or anything, resolution stays the same as what it is currently set to.
