NVIDIA Graphics-to-SDI

About the Software

The NVIDIA SDI software lets you specify the 

• SDI  signal  format

• Color formats

• Synchronization method

• Gamma correction

Graphics-to-SDI functionality can be set up and controlled in two basic ways—using the 
NVIDIA control panel or using the NVIDIA SDI API. 

Using the SDI APIs

The SDI application programming interface allows OpenGL applications to have full and 
exclusive control of the SDI output. This is also known as extended mode.

When the SDI output is under application control (extended mode), you can view the SDI 
hardware status using the NVIDIA Graphics to SDI property page.

• See the chapter 

 for a description of the graphics-to-video-out 

API calls.

• Also, refer to the document 

 for instructions on using the APIs.

Using the Control Panel

When the SDI output is not being controlled by an application, the SDI software works on 
top of existing applications, and the active workstation desktop or full screen application 
display is automatically forwarded to the SDI video outputs. This is also known as 
transparent mode. 

In transparent mode, you can use the NVIDIA Graphics to SDI property page to 

• Specify the SDI signal format, output format, and then enable the SDI output.

• Configure the external synchronization signal if needed.
