    What will happen if I disable my only display adapter


    An engineer at Adobe is helping me diagnose a problem with Photoshop. He suggested that I disable my AMD card from device manager and run Photoshop on the integrated graphics to see if the issue persists.

    When I check Device Manager, I see only one display adapter listed:

    Shouldn't the integrated graphics also be listed? If AMD is my only display adapter, I am reluctant to disable it.

    does this pc have a separate graphics card? If so then it also might have onboard graphics too. if it does then most likely you would have to remove the graphics card and use the onboard graphics. usually when a graphics card is installed it disables the onboard graphics in the bios.

    If you have an i7-4790 CPU, it should have integrated graphics---Intel 4600.

    My integrated graphics does show under Display Adapters in Device Manager. Not sure why yours doesn't---perhaps because it is not enabled in the BIOS.

    If you're referring to the XPS 8700 desktop in "My Computer", you'd need to physically plug the monitor cable into a port in the I/O panel. Look like the choices would be HDMI and Display Port. If you're using a DVI cable, you'll need a DisplayPort to DVI adapter. (If you need Dual Link DVI, that begins to get expensive.)

    A quick look at the BIOS settings (https://downloads.dell.com/manuals/a...nual_en-us.pdf) (page 76) doesn't show a setting for what graphics adapter is used. You may have to physically remove the Radeon graphics card to enable the onboard graphics. I believe that is disabled if a discrete graphics card is detected.

    I hope that Adobe "engineer" really is one, and not just making you jump through a lot of hoops. Call me cynical, but I've run into some rather odd advice from outsourced support people in the past.

    I've not yet seen a BIOS have a setting to disable the onboard/built-in video adapter. But it is quite possible to connect a monitor to an Add-in AGP or PCIe X16 slot and just not use the onboard connection, should be no interference. Logical thinking suggests disabling the onboard in the BIOS then removing the Add-in card or it failing would prevent accessing the BIOS to make any change necessary.

    I know on my 2008 dell xps9000 when adding a graphic card it disables the onboard graphics. I know in my bios their is no setting for onboard graphics. it just disables the onboard by itself until you remove the card then onboard will work.

    These are the Intel specifications:
    Intel(R) Core™ i7-4790 Processor (8M Cache, up to 4.00 GHz) Product Specifications
    Intel® HD Graphics 4600

    Removing the AMD dGPU should allow you to use the Intel iGPU.
    It may need a driver update from the Dell website.
    As a backup you can run:
    Intel(R) Driver & Support Assistant
