Hello everyone! I appreciate your willingness to help unknown people like me!
I am trying to help with a problem. House of worship. I am doing some research to see if I can get any input.
It seems that whenever a laptop is touched, the TV's at the front of the house are having to resync themselves, and make a big flickering distraction. As if it's static.
We have a sound desk at the back, with a laptop, and a mixer, etc. The laptop has a video connection to two large LCD tv's at the front of the hall, about 30 feet or so away.
From the HDMI port on the laptop, the signal is converted via a box into the digital coax type of video transmission cable. (I forget the name, and I am rushing a bit.) That cable goes to the front, and a splitter divides the signal to the tvo tv's, each having a converter back to HDMI. (Possibly converts to HDMI before splitting, I am getting the second hand.) We have mic stands on the stage, as usual, wired XLR balanced, yadda..
I think that is everything... and I hope this is the place for it... if not, could someone help me find the right place?
I don't have direct control over the system anymore, although I installed the sound part years ago. I have been asked to see if I can find, for the lack of a better term, some ideas with influence... ?
Does anyone have any good ideas re: what could be causing this, and, even better, something that could SOLVE it?
I thought maybe a better ground on the laptop, or a static pad for it to sit on.. if it even IS static..
Thanks everyone for your input!
