IZ2Stim Plot Display Requirements

Tech Note: TN0944
Product: OpenEx, SpikePac, OpenController
Version: All
Date Added: 2014-07-30

Issue

The IZ2Stim control included with SpikePac uses OpenGL 2.0 plotting. The version of OpenGL on the end user's computer must be version 2.0 or greater.

If a compatible version of the graphics driver isn't found when the IZ2StimGen control is run, the waveform diagram will appear empty and an error message is displayed in the plot area: Hardware acceleration not available. Please check the graphics card.

Solution

OpenGL is typically installed with windows as part of the graphics adapter driver and/or the graphics card driver. If the computer is using an outdated graphics driver, updating it should resolve the problem.

To update your video driver:

  1. Open your Device Manager from the Windows Control Panel.

  2. Right-click the graphics card or display adapter and click Update Driver Software on the short-cut menu.

  3. Follow the onscreen instructions.

If updating the graphics driver does not resolve the problem, contact Support for assistance.
