This CGA/EGA/YUV to VGA Arcade Converter PCB allows all types of RGB, EGA, VGA or YUV component signals to be up-converter and display on a 31KHz PC VGA monitor, TFT monitor, LCD display, or HD-TV with VGA connection. No need to set dip switches in order to figure out the specific input frequency as all inputs are detected automatically! A great alternative to purchasing a expensive, heavy CGA monitor. Use this converter with an existing computer monitor or install a light-weight LCD display or even use to build your own supergun!
