AI-generated summary
The document provides instructions for installing a HiDPI display configuration on macOS using a script. If the command fails due to a connection issue, it suggests downloading the installation package from GitHub or CSDN. After downloading and extracting the package, users are instructed to run the `hidpi.command` file and follow prompts to complete the installation, including entering a password and selecting the appropriate display resolution. It also addresses a potential issue where the monitor is not detected after installation, which can be resolved by unplugging and replugging the HDMI cable. The author suspects that the HDMI cable may be faulty, as it was purchased online and seemed to have a loose connection. The document concludes with a note that the issue did not recur after multiple attempts to replicate it.

  1. Open the terminal in macOS

    After entering this command, press the Enter key.

    bash -c "$(curl -fsSL https://raw.githubusercontent.com/xzhih/one-key-hidpi/master/hidpi.sh]]"

    If you see curl: (28) Failed to connect..., we cannot install via command, so we can install by downloading the installation package.

  2. Download the installation package

  3. After downloading, unzip and install,

    • Double-click hidpi.command

      • Here, choose the refresh rate of your monitor. Since I am using a 2K monitor, I chose the fourth option. If you see [Process Completed], it means the installation was successful.

  4. Restart the Mac.

  5. Compare before and after installation, open settings → Resolution. The left side shows the settings before installation, and the right side shows the settings after installation. Choose a suitable one on the right; I am using 1680x945 (HIDPI), which looks more comfortable overall.

    Problem: Unable to find the monitor, automatically exits?#

Here I record the reason:

The problematic options were as follows (unfortunately, I did not take a screenshot when the issue occurred):

Resolution had only two options: 1920 x 1080, 1280 x 720

Color profile: display

Refresh rate: 60 Hz, 50 Hz

Below is a screenshot after fixing the issue:

I connected the Mac mini M4 to the display using an HDMI cable, and the monitor accidentally lost power. When I restarted the monitor, this issue appeared.

I suspected it was a problem with the HiDPI installation package and struggled for a long time without resolving it.

Finally, I unplugged the HDMI cable from the monitor and plugged it back in, and miraculously, it returned to normal.

I seriously suspect that there might be an issue with the HDMI cable. The HDMI cable was purchased online and claimed to support 8k, but the connector feels loose and seems to have poor contact.

I tried to reproduce this issue again by repeatedly unplugging and plugging the HDMI cable, but the issue did not occur again.
