AW2723DF, problem installing firmware M3B104
Bought in 2021. So far everything has been good. But in the last 10 days I have noticed changes.
I never turn off my computer.
I have my monitor set to not go into sleep mode.
I just turn off the monitor and turn it back on the next day. Now for the last 10 days there is a sound when turning it on and off. Same as if I plugged a USB stick into the computer. Same sound when I turn off the monitor.
The light is blue when I turn on the monitor. When I turn it off, the light is off. When I turn it back on, it changes 4 colors in two seconds. Green, orange, red, blue. It's only been happening for the last 10 days. I checked to see if it's updated to the latest firmware. It's currently M3B101.
I am attaching three pictures.
it gets to 3 percent then error
Now I don't know what could be wrong with the monitor.

The firmware is not that important in my case. As long as everything works it's ok. This sound started to bother me and I automatically thought that the problem was the firmware. Because otherwise the monitor would have worked fine for 4 years. But now the sound appears when turning it on and off.

I never turn my U3415W off. Instead, I have screen saver set to Blank after 5 minutes. This way none of the peripheral devices plugged into the U3415W have to be reinitialized by the Area-51 R2.
* What is the warranty status? Click HERE. Enter the private Service Tag number. Do not post the private Service Tag number out here
* List every cable and device currently plugged into the AW2723DF
* If the AW2723DF is on and you restart the computer, does the sound appear?
* Have entered the AW2723DF Menu- Others and run the Factory Reset?

The monitor is fine. That is the OS notification sound for "hardware found". 10 days ago you had to have done some OS update to cause the issue. You are going to have to check the OS to see what changes were made. Or find that OS sound notification for "hardware found" and turn it off.
