We have an issue at work, we have installed an LCD 50" TV on the wall as a monitor to be used during meetings and training. I have run a 10m HDMI cord from the TV up through the ceiling and down the wall to a wall plug in the opposite corner. We use another 2m HDMI cord from a laptop to the wall plug. We use it as an extended display. It has been working fine for a couple of months.
The only thing that has changed is we took the TV off the wall to have the room painted, since putting it back, the TV will not display the correct resolution, it will only display 640x400. If we plug the short HDMI cable into the TV from the laptop, it displays fine and at the proper resolution. Has anyone come across this before?
