Dell Studio 15 - 2 external monitors

Posted on 2010-01-02

I have a Dell Studio 15 laptop that has a built in ATI Radeon HD 4570 video card.  It also has an external VGA port and an HDMI port.  Would I be assuming correctly that I could drive two external LCD monitors simultaneously with on hooked up to the VGA port, and the other hooked up to the HDMI port?

    You would think that but worryingly reviews and the Dell website say
    "An external display can be added by either VGA or HDMI"

    Interesting.  Can anyone confirm?

    I can confirm that has been the standard configuration in laptops for years now.

    Actually, according to the chipset supports one integrated LVDS display output & two integrated DVI display outputs. I'm not sure if the memory space for one of the DVI is shared with the LVDS, I'll so a bit more research.

    I called a friend who has a Studio 17 with an Intel video chipset and had him try. It looks like when you attatch a monitor to both outputs, one of them is mirrored on the LCD image, do you don't get three video memory pages. Sorry.

    Yup, that would be the standard configuration for laptops since the '90's.
    The intent is to mirror the internal display + have a TV-out.
    Older laptops used S-video or RCA component jacks for the TV-out, now they are using HDMI instead.
    It's really the same layout but now supporting HD TV resolutions.
