I have a small shop and a following problem. I have recently put up 2 tvs, haning from ceiling, between the tills (cash registers). The are arranged in the following manner: till1, tv, till2, till3, tv,till4. The tvs hang above the passage ways between the tills and play commercials from a usb memory stick.
What i want to do: Have a small over lay on each side of the tv with the till number. So the screen looks like this:
Once the till is operational the the side bar changes to green otherwise stays red.
Is it possible to do this? Where do i start?
Will appreciate any help from all yee gurus =)
