Do you hate the way MacOS handles your 2k (2560x1440) display resolution? Me too. Here's how to fix it. || [Free Tool for custom HiDPI Resolutions]

After a year of absolutely despising a 2K monitor which I discovered only too late does NOT play nice with MacOS, I have finally discovered some beautiful relief. I imagine there are at least a few other Hackintoshers out there who find themselves with the same problems - Like all native elements are really f---ing small, but scaling to 1080 is fuzzy thanks to no HiDPI support; messing with browser font sizes which inevitably messes up rendering for most websites applies changes across other monitors too (so if I want something readable on my 2k monitor, the same browser on my other 4k monitor is now readable by a legally blind man across the room).

Well, some charitable Russian saint on Github just gave us an enormous quality-of-life improvement. It could not be easier to use either. It's a simple App, lives in your menu bar, doesn't require SIP to be disabled. It's just everything I've ever dreamed of and I'm so happy I could just about cry.

I am using the HiDPI for creating a 2048x1152 scale on a 27" LG 2K monitor (the 27GL850 to be exact). This resolution keeps my picture quality crisp while perfectly matching element sizing to my 27" 4k monitor (which has always been natively supported with HiDPI).

You'll want to play around with the different available HiDPI resolutions depending on your display's native resolution and screen size.

Here's the link to the Github Repo - See "Releases" on righthand side, 2.3.3

NOTE: I am still on Catalina. I have no idea whether or not this app supports Big Sur. Guessing it does but check first if this applies to you.

Here's a (almost certainly unnecessary) Medium guide - The app is about as self explanatory as it gets but just in case anyone finds that useful.

NOTE #2: You may need to disable SIP for setting custom resolutions depending on which OS you're running. I did not need to even mess with any of that because the latest version (2.3.3) had all of the relevant HiDPI resolutions already bundled in for 2560x1440 (2k).

NOW GO SWEET CHILD, GO ENJOY YOUR 2K MONITOR AS YOU'VE ALWAYS DREAMED!
