Hardware acceleration is enabled by default with Intel® HD Graphics drivers; however, it is necessary to uninstall the driver in order to disable hardware acceleration.
I did disable the Intel driver, returned to a standard Windows driver, and was able to disable hardware acceleration.... the application then worked....but... at a severely reduced video quality.
The generic Windows drivers do not support dual monitor, high-res video required to run the other applications that my users require. The Intel driver(s) that I have tried support the required video modes (hi-res, dual monitor, etc.) but they do not allow me to disable hardware acceleration, which renders the video application that I need to run useless.
I need a driver that supports the display adapter's video modes/capabilities and allows me to disable hardware acceleration.
Since hardware acceleration is enabled by default once you install the graphics driver, this will take control of the graphics acceleration and cannot be disabled.
