M1 Mini screen flashing and repeating noise from speakers

I'm running a M1 Mac Mini connected to a Samsung LS32A70 monitor using a new HDMI cable. From time to time the screen will flash very much like the flashing alert setting on an iPhone. Sometimes it will momentarly stop as I move the mouse around. Another equally annoying thins also happens without warning is the screen will wobble from side to side.


ADDITIONALLY:

A rapidly repeating alert sound also occurs for no apparent reason. The sound changes if a change the Alert sound in System Settings. Clicking the apple icon halts the sound until something else is selected.


I have had this system up and running for 9 months and cannot find the cause of either issue. The HDMI cable is not a cheapo and I have checked all connections.


A system restart returns things to normal ... until next time.


Any ideas???

There is a firmware update for this monitor on Samsungs support page. In the User Manual it describes putting the firmware update BIN file on a USB flash drive and plugging in the drive to the monitor and using the monitor menu buttons to navigate to software update and it will update the firmware on the monitor. The firmware update is version 1012.2 dated Feb 20th 2023. You should be able to see the current firmware version in the monitor controls and menus.

Update software using an update file on a USB device.

    1. 1  Save the update file (in .bin format) that you downloaded from the Samsung website (http://www.samsung.com/sec) to a USB device.
    2. 2  Connect the USB device to the port on the monitor.
    3. Select → Support → Software Update.
    4. 3  Follow the instructions on the screen to proceed with update.
    5. 4  Your product will turn itself off and on again automatically after completing update, and then turn off your product.
    6. 5  Remove the power cord from the power outlet and then reconnect the cord after turning off.


    • ―  To perform software update by using a USB device, first format the USB device to FAT32.
    • ―  When updating by a USB device, be sure to use the device whose version of USB 3.0 or lower.
    • ―  When performing update, make sure that only one BIN file (.bin) is saved in the root directory.
    • ―  If the No USB devices detected. Please check and try again. message is displayed, this is probably due to the following reasons.
    • ―  A USB device is not connected to the port.
    • ―  The files in the connected USB device are not compatible formats.
    • ―  There are no valid update files found in the connected USB device. (There are no update files saved in the memory or the file names are incorrect.)
    • ―  The update will not start if the downloaded software does not match the software installed on the monitor. To check the software for consistency,
    • select → Support → Information.
    • ―  Do not turn off the product until the update is complete. And prevent the updating from any interruption as far as possible. In general, the product
    • returns to the previous version if an update is interrupted.
    • ―  It may change the screen color or blink during USB update, but it is not a monitor problem. Since S/W update is performed normally, please wait until
    • the update is finished.

I followed all steps to the letter and it didn't work! The error message said it could not find a bin file. I formated two different USB thumb drives each to FAT-32 and copied the downloaded file M-A8000SGZA-1012.12[351.A].bin to the drive. Pluged it into my Samsung LS32A700NWXTZA monitor. From what I can find that .bin firmware upgrade is for a S32A704NWS monitor. I have also look for a firmware update file for my monitor but no luck. Perhaps I'm just holding my head wrong.


Any ideas?
