Hi Holly, >>> I’m trying to attach an external display to my G4. It was working and I disconnected it to rearrange my desk and now I can’t get my G4 to detect it. I’m wondering if it’s a problem with the connection to the TiBook. The video plug seems loose and if I try and use the attached screws to tighten it to the back (of the TiBook) they don’t connect (so I can’t tighten the cable on to the back). <<< Sounds like you should try to get the cable to fit better. I sometimes have trouble getting the screws to screw, too. I have to hold the plug tight to to back of the TiG4 and gently attach it. Mine doesn't take much. I just get one side just started & go right to the other. The key is getting the plug all the way in to the back of the TiG4 and sorta feeling the screws catch. It really does fit! Let us know if you get it working properly. Good luck, Frank Wiewandt
