Trying to do a little research for my daughter who lives in another state. She had been connecting her laptop to her TV using a HDMI cable. Supposedly, it was working just fine. However, I suspect she might have been "experimenting" and changed some settings (she doesn't seem to remember), but now when she plugs them together, her computer screen goes black and there's nothing on the TV. Any ideas?? Edit: Another small clue has surfaced. Apparently she right-clicked on her desktop and then clicked "Outbound." Not sure if Outbound was right there in that little menu -- or if she first opened "Graphic Options" and found it in there. Either way, she clicked it and that's when the problem started. I'm not sure what "Outbound" is, but she said she went back to un-check it, but it was no longer there.
Hello TomAZ: Can you please say if your daughter's system has a recent and frequent full system back-up strategy, or a recent group of daily System Restore Points (SRP)? Thank you.
Have her use the NVIDIA or AMD control panels and reset all options back to defaults and do the same for display properties.
Im assuming shes on Windows 7. Should be similar for an OS though. Start menu > Control Panel and then either the AMD Catalyst or NVIDIA control panel will be in there.
