Is not documented that I can find BUT it works !!!!
Hold down Menu Button + Power for 7 seconds. Then let off for a few seconds and hold down the Menu Button until you see the special / hidden blue menu on the far left of the monitor.
Anyone know what ALL the settings mean ????
One can set them manually but not sure if there is a Factory Reset if one messes up !?!?!?
Any Documentation would be MOST HELPFUL.
Thanks for sharing,
