Hi, Anyone have some thoughts on the following...I use a PC monitor that has two HDMI inputs to share on a PC scope and a catv box. All was good until a few days ago and the scope apparently had a spike and the monitor lost the picture. After rebooting the PC and catv box the monitor works fine on the PC but the cable box can not access the monitor. It keeps looking, but doesn't ever find how to make the connection work. I tried all the various settings on each of them but nothing worked. It is not a resolution / scan issue as I tried all of them. It almost seems as if the monitor lost the ability to talk back to the catv box. It is a bi-directional one on COX. A Cisco 4742HDC. The monitor is a LG 24GN50W. The PC apparently is not bi-directional and really doesn't care what is hooked up. All this stuff worked fine for a long time.
Good Listening
Bruce
