Now, the monitor seems to be stuck in a loop. I click the "auto/select" button to make the "OSD LOCKOUT" message in the middle of the screen go away, then it brings up my monitor menu (with like, brightness and those options). When I click ANY button to move the cursor in the monitor menu, it goes into the brightness option, and then if i click ANY other button, it goes to the exit on the main monitor menu. It won't allow me to select any other options on the menu.
I tried holding in the MENU button on the side for 10 seconds to disengage the OSD LOCKOUT, but it didn't work. It continues to pop up with the monitor menu, or get stuck with the OSD LOCKOUT message in the middle of the screen. I have also unplugged the monitor from my computer and its power supply, rebooted my computer, and tried to re-download and install the drivers, and I'm still having the problem.
