Mac Book pro - M3 Pro chip - Doesn't recognize the monitor after waking up from sleep.

When my MacBook Pro goes to sleep if it doesn't have any activity for a while, once it wakes up from the sleep, my monitor won't recognize the connection any more and the monitor goes sleep saying 'No Input signal'. I made sure this is not an issue with the monitor because, when I tried with another windows PC, this is not the case.

My device details:

Mac Book pro 14 inch with M3 Pro chip

OS: Mac OS Sonoma 14.2.1 (23C71)

This could be a compatibility issue or a glitch with your MacBook's settings. Try resetting the PRAM/NVRAM and SMC on your MacBook Pro. To reset PRAM/NVRAM, restart your Mac and hold Option + Command + P + R keys simultaneously until you hear the startup sound twice. For SMC reset, shut down your MacBook, then hold the power button for 10 seconds. After resetting both, see if the issue persists. Also, updating to the latest macOS version might resolve compatibility issues. If the problem continues, contacting Apple Support for further assistance might be helpful.
