"No Signal" with DVI to VGA adapter.

DVI to VGA adapter - Analog signal strength?

  • I got a VGA monitor cable connected to a DVI to VGA adapter and they're connected to a VGA monitor and a video card with a VGA & DVI port (DVI port is the one that I want to put to use). I already know that the signal is going to be in analog. My question is the "analog signal" going to be stronger, weaker or just the same signal?

  • Answer:

    Stronger or weaker than what? You will get the best signal with a high quality DVI-A to VGA cable. Any time you add an extra connection the signals need to get exposed from their co-ax cables in the wire, you will have some impedance and bandwidth limits on the connections, so you will have a 'weaker' signal than a straight connection. How much weaker? Probably not much. Would you be able to tell the difference between a DVI-A to VGA cable and the monitor VGA cable + a DVI-A to VGA adapter? Probably not. If there was a difference it would probably be very subtle.

Wondered the same when I hooked up mine. Theres no difference mal. Save the dvi connection for a dvi device thats very high quality or you'll be disapointed instead of enthused.
