Ever been on a tradeshow floor during a set up?
Image This: You are setting up a video wall 4 screens (2x2), media players and video controllers. Just one problem - the set up was tested with the monitors only 5 feet from the media players. On the floor in the structure that they are mounted on has no place to put the media players. (This was a very last minute add on by the client.) It is 20 feet away.
But wait - you have planed for this - you have the cable. It is all good to go.
Wait! There is no way to run the cable from the monitors to the media player.
No problem - you have a job box - you have the means - you drill holes and then you cover the holes with grommets. It all looks good.
So maybe it shouldn't be Never Give Up! It Should be Plan, and Plan Again!
