checking VRAM in DirectX

A Windows operating system uses an API (application programming interface) called DirectX to allow programs installed on your PC to work with the video and audio of your computer. You can bring up the diagnostics tool for DirectX by going to Run and entering: dxdiag

The DirectX Diagnostic Tool will have tabs for each set of monitors and speakers connected to your computer. A tab named 'Render' will display information for the dedicated graphics card on your PC. It will show the VRAM for your PC - the amount of computer memory dedicated to graphics:

The very first tip of the night on April 12, 2015 warned to never try to use Trial Director or other presentation software for a courtroom electronic presentation without confirming that your laptop has sufficient VRAM. Trust me, I know from bitter experience that video clips for deposition designations with multiple segments will not play back correctly on a laptop without sufficient VRAM. The current version of Trial Director requires a graphics card with 4 GB of dedicated graphics memory. See the specs posted here.

Use the DirectX Diagnostic Tool to check how much VRAM the monitors and projectors you are connected to will require.
