ATI Radeon Moblity HD 4650

Hello. I have a ATI Radeon Mobility HD 4650 installed in my Dell Studio 17.

I need to know if this card is capable of running two external independent displays in addition to the laptop display. I have a HDMI output and a VGA output. What would I need in order to run two external monitors. I have tried one monitor on HDMI (w/ HDMI to DVI cable) and another on VGA but I have had no luck.

Thanks.

  1. Are you trying to run them like an Eyefinity setup or all displaying the same thing?
    Here are the Specifications of the 4650 straight from Ati's website...

  2. Thanks for the reply purple stank. I am fairly computer-tech-illiterate. I read the specs before posting the question. I saw where it says "Drive two displays simultaneously with independent resolutions, refresh rates, color controls and video overlays for each display".

    I do not know if that means it can drive two external displays + the laptop display or if 2 display would include the laptop.

    I am not sure what an Eyefinity setup is, but to be clear I need two external moniitors and the laptop monitor to all be an extended desktop and not just a mirror of each other.
  3. I do not think it is possible for your card to do what your asking of it...if you read here it will tell you everything oyur card can do/can't...

  4. OR maybe it would work if you had a splitter,but this is just a guess...you see you need more than 1 connection for a dvi/vga to make it work and this card only has 1 of each.Have you tryed going with a VGA to DVI connector?
