Black box in the middle of the screen

We have this monitor set up in all our operatories for patient viewing. All work great - except one. This one when you turn it on, all is ok for a few seconds, and then a black square appears in the middle of the screen and takes up about 3/4 of the entire screen. This only started happening about 1-2 weeks ago - and we've been utilizing it for over 2 yrs. Any thoughts? and thank you in advance.

Very easy fix, The problem is you have the TEXT close caption ON. Just go into the TV menu and turn the close caption OFF.

What about the TV settings? Does it have PIP or some other mode that would overlay an image on the program already playing on another input? Or is the black box only there when you monitor the input from the HT?

Dialogue box in the middle of the screen

Out of range usually means that the computer is trying to use a resolution that is unsupported by the monitor. Try loading the PC in safe mode (for windows, press F8 before windows loads) and change the desktop resolution to 800x600, which is supported by pretty much any monitor. Restart the computer normally and you should get your video. Once inside windows you can experiment with different resolutions, and when it goes out of range, just wait 15 seconds for it to go back to 800x600.
