Connection Monitor to PC ???
I discovered something that surprised me - maybe someone can tell me
why? I connected my monitor to two PCs, one DVI, the other VGA. I planned to used my two PCs together, but never at same time. Guess what? My PC connected with VGA worked alone. buy stopped working once I connected the DVI cable. The DVI PC worked fine. I even unplugged power to the DVI PC!! Now I am plugged to only the VGA PC and all is fine. What don't I understand? This is all because my MINIVIEW SYMPATH 4-VGA-PC monitor-mouse-keyboard-connector quit working after several years use. Just quit. Further, my cables no longer want to want on the Sympathy. Seems strange. I am discouraged to say the least. Johnny |

If this was my kit to debug, I'd have the ohmmeter out and have all three devices disconnected from power. See whether the VGA pins on the DVI-I connector on the monitor, are in common with the VGA pins on the VGA connector on the monitor. The two monitor connectors could also share a common SDA/SCK (serial bus for EDID monitor resolution info). Using the make and model number of LCD monitor, I would be looking for Newegg customer reviews for this particular monitor. Someone else will have seen this happen. Paul Then maybe what I canf irst try is a second monitor I have? J |

Paul Of course none of this would have happened if my 5 year old my MINIVIEW SYMPATH 4-VGA-PC monitor-mouse-keyboard-connector no longer seems to handle the VGA cables I have been using. Strange. The cable ends now won't fit on the connector. All 4 of 'em. Looks like someone sat on them but I know noone did. All was okay until I dismantled and moved all my computer stuff to another room Then I cud not re-assemble things. I don't understand why things are the way they are. And then the fact that I cud not connect 2 monitors really threw me. Life can be strange. J |

What gets me is that my MINIVIEW SYMPATH 4-VGA-PC monitor-mouse-keyboard-connector worked for 4/5 years, and gave me trouble only when I dismantled everything to move. When I went to re-assemble everything I quickly found that I could no longer connect the VGA cables to the 'box'. The cables are/were nice beause they contain connections for mouse and keyboard which means in my case one keyboard, one mouse, one monitor for up to 4 PCs selected by choice. Now I can't connect the same cables. I am flabbergasted! Go figure. I'm gonna hafta try them again! I am missing something. J |

J I am on my second machine now - hence the different signature, Anyway I have tried using the connector again and forced the VGA cnnectors and I have one PC working (this one). but , try as I may, I just cannot connect the second macihine. So. I am stuck. J |
