    Dell Optiplex graphics driver failure


    by rebeccat2850 ·

    I turned on my Dell Optiplex 3020 desktop PC today to find that the screen resolution is very low with 4:3 resolution stretched. Windows 11 settings show only 1024×768 resolution. The menu on the monitor shows a native resolution of 1600×900 but no way to select that. Device Manager shows that the Intel 4600 graphics driver has a fault, with the message: The driver for this device has been blocked from starting because it is known to have problems with Windows. Contact the hardware vendor for a new driver. (Code 48)

    After looking on the Dell community forum for assistance, I have:
    – uninstalled the graphics driver and restarted
    – installed an earlier version of the driver from the Intel site
    – used the Custom Resolution Utility to manually change the resolution
    – used the Intel Graphics Command Center which does not show any option to change resolution, probably because of that fault
    – used the QRes utility to force a resolution change which produced an error message stating 1600×900 is not supported

    Does anyone have other suggestions? Eventually I will have to get another PC if I can’t fix this.

      I see the machine some 7 or 8 years old. If, except from this issue, you’re still happy with it, consider to only add a video card to replace the built in graphics.
      If you prefer to buy a new and faster PC, that’s very well possible of course.

      Old PCs with Intel Graphics have this issue. To fix it we pop in a cheap video card. If some 20 buck video card isn’t worth it, then maybe they should try Linux?

      Your Dell Optiplex 3020 desktop PC is experiencing graphics driver issues, resulting in a low-resolution display. Despite trying various solutions, including driver reinstalls and resolution adjustments, the problem persists. To further troubleshoot, ensure your Windows 11 is up to date through Windows Update, and visit Dell’s official support website to download the latest graphics driver specific to your model. Additionally, consider updating your BIOS, using a driver uninstaller tool, or rolling back to a previous driver version. If the issue remains unresolved, contact Dell’s customer support for specialized assistance. Always back up important data before making significant system changes.
