This is weird an annoying, I run my laptop through a monitor when I'm at home, and the monitor goes totally blank for a couple of seconds every five minutes or so. It's acting like a loose connection, although I have checked both ends of the cord and that isn't the case.
It also does this with two different laptops, so I'm guessing it's something in the monitor. Or could it be something internal to the cable?
Any troubleshooting tips? It's a cheap-ass bottom of the barrel LG monitor, but it's all I need and I would prefer not to replace.
