Follow these steps if you cannot increase your display resolution in Windows.
Detecting and fixing video driver problems
If you can’t increase your screen resolution in Windows, your system may have corrupt or missing video drivers. Follow the steps below to help resolve this issue.
If you cannot get into normal Windows or you cannot see anything in Windows, boot the computer into Safe Mode.
Open the Device Manager and verify that no conflicts or issues are displayed on your video card or any other devices. Also, verify that there is no Other Devices category. If issues exist, resolve these issues before continuing.
How to Identify problems in the Windows Device Manager.
If Device Manager shows conflicts on your video card or your video card is a Standard display adapter, remove all video cards under the Display adapter category. To remove them, highlight each device and press the delete key until the Display adapter category is gone.
After following the above steps, reboot your computer.
Windows should re-detect and install the video card and any other devices you may have removed or fixed in step two. If Windows asks for files you do not have, you may need to obtain the drivers as mentioned in the next step.
If the above steps do not resolve your issue, obtain the latest video drivers from the computer, video card, or chipset manufacturer. You can find a link to video card manufacturers and chipset manufactures on our video card drivers page.
What video card does my computer have?
Change video settings through video card software
Many video cards may have software to help manage and control your video card settings. If you’re unable to adjust the resolution in Windows, try adjusting the resolution through the video card software. Often these programs are running in the background and if available are shown in the Windows Notification Area.
Not enough video memory
If you’re attempting to increase the resolution beyond 640 x 480 - 256 colors, first verify your computer has enough video memory. If your computer was manufactured in the last three years, you have enough video memory to support a higher resolution.
If your computer has previously been able to support your desired screen resolution, then video memory is not causing the issue.
If you cannot determine how much video memory your computer has, contact your video card manufacturer or computer manufacturer for additional information about your hardware.
