You've noticed on your Windows workstation that sometimes your mouse cursor appears strange on the screen. In addition, images in Web pages you are viewing appear to be corrupt. How can you fix this problem? Increase the color depth displayed by the video adapter. Upgrade to the latest version of your Web browser. Decrease your video adapter's hardware acceleration. Increase the video adapter's display resolution. Increase the video adapter's refresh rate. Explanation You most likely need to decrease your video adapter's hardware acceleration. This will disable cursor and bitmap accelerations which should resolve the issue. At some point, the video adapter itself should be upgraded. Changing the resolution setting changes the size of text and windows in relation to the screen. Changing the color depth affects the number of colors that can be displayed at one time. Upgrading to the latest version of you browser will not correct how the mouse itself appears in contrast to the rest of the display. Increasing the refresh rate changes how often the screen is updated.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
