macOS Monterey 12.3 would cause problems for displays and external controllers

Source: Pocketnow

A week ago we reported that macOS Monterey 12.3 crashed some MacBook Pro laptops that had logic boards previously replaced, and it looks like there might be even more issues with the latest version of macOS. Users are reporting issues with external monitors and game controllers after updating to macOS Monterey 12.3.

Display issues

Several users have reported (via MacRumors) on the Apple forums, claiming that their Mac can no longer display video over USB-C. So far, the issue only seems to affect third-party monitors from BenQ and LG, and it doesn’t seem to be relevant to the Apple Studio Display launch.

POCKETNOW VIDEO OF THE DAY

Some users claimed that they were unable to connect their Mac mini on macOS 12.3 via USB-C, while others claimed that the HDMI connection was also not recognized. According to a user on the MacRumors Forums, the problem is that macOS does not recognize the DisplayPort protocol version, which can be fixed by changing the version to an older version, resulting in lower image quality.

“I solved this problem (on 2022-03-15). On my monitor (LG LCD 27 27UN880-B IPS), I went to settings and lowered the DisplayPortVersion from the default v1.4 to v1.2. As soon as I lowered the DisplayPortVersion of the monitor, my Mac with OS X 12.3 started recognizing the second screen correctly. It looks like the new OS X update has issues with a DisplayPortVersion 1.4 protocol (has faster data rate, faster refresh and stream compression). I hope this helps you.”

Some users have suggested that unplugging the external display for a short time, plugging it into the Mac, and then plugging the display back into the power outlet might work and fix the problem.

Controller issues

Some users are reporting that they cannot use their PlayStation, Xbox, and other third-party controllers via Bluetooth. The issue arose after updating to macOS 12.3, and many users reported issues on Apple developer forums and Reddit.

The vast majority of affected people claim that they cannot connect their controllers to play Apple Arcade games and other non-App Store games on their machines. The problem seems to affect most games, although it’s currently a mystery as to what caused the problem, as it seems to work in some games, for a few people.

“Same issues here. My controller works in some games, but not everywhere:

  • macOS: 12.3 (21E230)
  • Xbox Wireless Controller:
  • Manufacturing ID: 0x045E
  • Product ID: 0x02FD
  • Firmware: 9.0.3
  • Additional Type: Gamepad

Working in apps:

  • Steam
  • Pac man party
  • The pathless

DOES NOT WORK in applications:

  • Sonic Race
  • Asphalt 8+
  • Agent Intercept”

Users are currently encouraged to try removing and reconnecting controllers using Bluetooth settings, but this is currently not known to be a workaround to fix the issue. Apple has yet to acknowledge the issue, but we expect to see an update soon to address the issues newly introduced in macOS Monterey 12.3.
