Losing video during game play
If you are losing video when running a computer game or program that uses DirectX, it is a good possibility that DirectX may not be correctly switching the resolution.
Most games use at least 1280 by 720 pixels with 256 colors. Try changing your display resolution to 1280 x 720 (or your monitor's recommended resolution).
Unsure what resolution you monitor should be set to? Drag the slider as far left as it goes. Also, make sure the color palette says 256 color; if not, click the down arrow next to the current color and select 256 Colors. Finally, click Apply (restart the computer if needed) and attempt to run the program again.
If the above suggestions don't help, ensure your hardware is compatible with DirectX and that you are utilizing the latest version of DirectX.
