Displaying or Updating an Image is Slow

This article applies to:

• Kurzweil 1000

• Kurzweil 3000 for Windows

Symptoms

Displaying the image of a page is slow. When the image scrolls from side to side or up and down, it can take a few seconds for the image to be painted on the screen.

This problem can appear in the Kurzweil 1000's Show Image window or in the Kurzweil 3000 when displaying an image.

Cause

Some video cards have an acceleration feature that, oddly enough, slows down the display of images in Kurzweil products.

Solution

The solution is to lower or turn off video acceleration. The performance of other applications, or your overall system, will usually not be noticably affected, with the notable exception of video-intensive games.

Changing video acceleration is slightly different depending on the operating system.

On Windows 95:

From the Start button's menu, choose Control Panel. Open the control panel for Display. A tabbed dialog will appear. Select the Settings tab. On the Settings page, click the Advanced Properties button. Another tabbed dialog will appear. Select the Performance tab. On the Performance page, there is a slider that adjusts the video acceleration. Slide it all the way to the left. Click OK on the two tabbed dialogs.

On Windows 98 and Windows ME:

From the Start button's menu, choose Control Panel. Open the control panel for Display. A tabbed dialog will appear. Select the Settings tab. On the Settings page, click the Advanced button. Another tabbed dialog will appear. Select the Performance tab. On the Performance page, there is a slider that adjusts the video acceleration. Slide it all the way to the left. Click OK on the two tabbed dialogs.

On Windows 2000 and Windows XP:

From the Start button's menu, choose Control Panel. Open the control panel for Display. A tabbed dialog will appear. Select the Settings tab. On the Settings page, click the Advanced button. Another tabbed dialog will appear. Select the Troubleshoot tab. On the Troubleshoot page, there is a slider that adjusts the video acceleration. Slide it all the way to the left. Click OK on the two tabbed dialogs.
