    I have a Sega Teradrive PC connected to a Gobes GBS-8200 V4.0 converter via its DB15 VGA input, the converter VGA output then goes to a Dell PC screen (I've tried my LCD with the same results). Basically, the Sega MD side 15 Khz VGA signal displays fine through the converter (RGBS), but the IBM PC side 31 Khz VGA ouput refuses to display properly through the same input and cable, all I get is a distorted and frozen screen (RGBHV). I've tried different setting with little success, I was into thinking the GBS-8200 could handle EGA/CGA and VGA 15/24 and 31Khz input signals. Am I overlooking something?

    Any help is much appreciated, or if someone can point me in the right direction that helps too. Thanks in advance.


    Teradrive MD side>VGA output>15khz> GBS8200 input>GBS8200 VGA output

    Hold in the "auto" button on the gbs with it all turned on....

    I forget how long you have to hold it in for, so just do 5 seconds and see what happens...

    The "down" button is the auto button, but the gbs is pretty horrible anyway...
