U2413, input source select without buttons?

I need help with my U2413 monitor. Is there a way to change the input source without the buttons? The menu buttons are locked and I've tried doing all the solutions on this forum and they are not unlocking. The menu lock section did not work, I've also tried your recommendations and nothing. The monitor is stuck in DVI-D source and I can't change it to anything else. I've plugged HDMI and display port cables but the monitor won't detect the source change. Is there a way to reset the monitor? What else do you suggest?
