Acer G257HL Monitor lost its firmware or stuck in some kind of self test

I have this great looking monitor that won't display an image from the computer. As soon as power is connected, it starts cycling through an RGB test of the screen, showing solid screens of one color, and then it turns the power off for a moment and turns back on, restarting the process. Pressing any of the buttons results in a small popup above the buttons showing information like: "FW Ver: 092 20141016, SN: (yada yada), Auto Color: Undo, Panel: RB5LM250WF5-SAA1, Key 0 Pressed". This varies with the keys in that it shows "Key 1 Pressed", etc. Anyone have knowledge whether this can be gotten out of and returned to functionality?

yeah, same problem here, I've had it since 2018 but never really had anything to maybe solve this issue.

Try this: turn off the monitor, then while pressing the 'e' key press the power key to turn it on. The only thing you should be able to change there is the language, but it might have a demo or test mode set.
