SOURCE: OSD LOCK
You are having a problem with the OSD lock on your ViewSonic Monitor. Is that correct?
If so, please follow these instructions to unlock or lock your monitor.
On some display devices, there is an OSD Lock that locks all current control settings and prevents access to the control menus until this mode is unlocked.
The method for unlocking the OSD is different for different monitors, but will be one of the 2 below. If the first method doesn't work, try the second.
Method 1: Press and hold both the  button on the front of the monitor and the down arrow button for 10 seconds.
Method 2: Press and hold both the  button on the front of the monitor and the up arrow button for 10 seconds.
Note: These same buttons, when pressed for another 10 seconds, will lock the OSD
Please let us know if you require any further help with this matter.

i think the main board is flaky in that monitor. Hook up another known good monitor to that computer and see if it behaves in the same way.
If it does behave in the same way then you know its either the video card or the motherboard if you have an integrated video connector to the motherboard.
If it goes away then you know the phillips monitor is bad.
If its the phillips monitor that is bad for sure. You can try taking off the front cover and try cleaning the contacts on the main board in the front of the monitor. Could be that a few of them have dust or dirt and is activating those buttons by accidents inadvertently.

OSD (On Screen Display) lockout. To resolve the issue you can hold the power button of the monitor until you get another message something similar to "OSD unlocked"
try holding menu button also if it doesnt workout
