M1 Macs don't use display overrides so we can't do workarounds for some problems. Now Im unable to get HiDPI resolutions on the native resolution of 2560x1440 and on 1920x1080. The CAC-1510 requires four lanes of HBR to support 2560x1600 mode. Maybe try connecting the adapter to a Thunderbolt 3 dock.
The HP Thunderbolt Dock G2 has a USB-C port that is part of a MST Hub which might be useful because it can convert two lanes HBR2 or HBR3 to four lanes of HBR (in case some lanes aren't working). It sets HiDPI 1024圆40 (via SwitchResX), and various other ones, but all of the 4:3 HiDPI modes are simply failing to set. If you want to enable the HiDPI Mode on your macOS X Lion Screens, follow the steps below. I you want to try adding a custom resolution, the timings for the supported modes 49.306kHz 71.00MHz h(48 32 80 +) v(3 6 14 98.529kHz 268.00MHz h(48 32 80 +) v(3 6 37 -)but M1 Macs don't use display overrides so it probably won't help to create a custom timing. After installation, you then click System Preferences > Other > SwitchResX > select your Mac. I think I could get work done on it at this 1024圆40 setting while its missing a good 256 lines of retina display but Id rather have it work the way it really should :( Any ideas P.S. #GET HIDPI SWITCHRESX INSTALL#įirst of all, download and install XCode.
It is a free tool available on the Mac Store. Picture C Do NOT try to choose 2560 x 1440, though. After that, open ‘Quartz Debug.’ Further, it is located in Developer>Applications>Performance Tools Now pull down the ‘Window’ menu and click on ‘UI Resolution.
#Switchresx free how to
Some other tutorial shows how to add custom resolutions with Switchres and Quartz Debug.
