Question about NEC LCD4000 40 in. HD-Ready Television
I have a TV that is setup in the operating room and we can change to different areas and view Xrays, heart caths and ECHOS from other areas. The problem is when the cath lab is pulled up live it gives me a red sign that says Attention The frequency signal is out of range. Please change the signal timing. Just below the words there is H: 77kHz V: 72Hz How do I change that timing?
Try this. The signal timing of the monitor is picky in the fact that it must have 60hz. Try changing the source of whatever is feeding that monitor to output 60hz signal. That should fix your problem.
