I have a DVR box with 4 cameras, the vga lead is going into a sony bravia tv. I was able to adjust everything through the tv with a mouse on the camera menu. Yesterday I inadvertently hit a higher resolution on the menu now I am getting this message on the tv. I know the resolution needs readjusted but I don't know how to do it. Do i need a screen with a higher resolution? Do I get a vga to usb to connect this into a newer screen ? please help
