I'm new to these tech stuff, I'd appreciate an advice. I'm planning to set up LED screens in a location far away from my operating place. The screens I'm planning to set up are these: LED Screens. I want to be able to control them from far away. What I mean by control is that I want to be able to change the images viewed, control the brightness, resolution etc. What kind of device should I use to meet this requirements. Please don't suggest high-tech stuff, I hope it's a single thing and it lets me control the screens via an app or etc. Thanks.

 

I would suggest you talk to manufacturer with those details.

 

The cheap trick for remote control is to use LCD TV sets as the display device, rather than computer monitors. They normally come equipped with a remote control.
BUT avoid any product that does not also have controls on the actual device. They become useless when the remote fails for any reason.

 

How you are able to control them will depend entirely on what equipment you choose to generate the visuals for the displays. I agree with sghioto; talk to manufacturer about those details.
