dual monitor software

Posted on 2010-01-04

I have two monitors coming out of one vga output on my pc. The output is identical as I want it to be, but one of the monitors can only handle 1024X768 so I have to keep them both at that. Is there any software so I can let them each have a different resolution?

    There is not software that will do that... You'd need dual outputs on your video card (or two video cards) to accomplish this.

    Unless your video card software has a scaling option for a second monitor, probably not.  I had a video card with that ability a while ago - 1024x768 on the main screen and it was downsizing for a TV-out.  Might want to try updating the drivers for your video card and see if the newer ones have it.

    It's not a popular or much-requested feature, so it's probably going to be hit or miss as to whether your card supports it.

    This will depend on your graphics card - if it is integrated then the odds are you are stuck.  Separate cards are more likely to support this.
    What card are you using?

    Several Video card's drivers have that option embedded.  I'm very sure you can do that in nVidia cards without no 3rd party software. I cannot assure the same with ATI or other brands.  If nVidia is your card's brand, update it to the latest driver, then go to properties with both monitors connected and you will be able to see both screens and configure each one's resolution individually

    Accepted Solution

    The issue you have here is that you are splitting the signal out to the monitors from a single source. Because of this you will be relegated to the lowest denominator, in this case that is the 1024x768 display.

    There is absolutely no software application or driver option which will be able to manipulate the resolution of separate displays which share one feed.

    If you would like to run each display at a different resolution you will have to provide each display with it's own signal source. As mentioned by others in this thread, this may be achieved by either using a video adapter with two outputs or by simply using two cards.

    The easiest solution will be to use one card with two VGA outputs. This will keep you from sorting out driver issues and primary VGA issues which you are sure to run into.

    > 1. Determine what type of add on cards your system will except (AGP,PCIe,PCI)
    > 2. Purchase a card which will match your performance requirements and system expansion capabilities.
    > 3. Download the latest drivers for your new card from the manufacturers website and store on your local drive (desktop works fine).
    > 4. Turn off the machine and uninstall the old card (if onboard, disable in system BIOS)
    > 5. Install new video adapter and boot system.
    > 6. Click cancel on the windows 'Found New Hardware' window.
    > 7. Install new video drivers.
    > 8. Reboot
    > 9. Go to driver settings, highlight the second display and choose usage option you desire (extend or clone).
    > 10. Set desired display settings (resolution, etc.)
    > 11. Enjoy :-)

    >one vga output

    Your video card determines the resolution; that means there's only one video signal going out - you can't change it downstream without inserting a scaler between the monitor and card.  It would be cheaper to get another card.
