    To all: Thank you for your help and sorry for my english...

    To Meek: naturally I've tried to disable the pin n°16 and the RGB out of the video board is disabled too. Without this pin, if you try in the DVD MAX menu to select between SCART, RGB and COMPOSITE the result is EXACTLY TH SAME.

    To Tony and Sirio_KD: If you've some schematics that can help me, you can send those to: pdl.roberto@tiscalinet.it or pdl@users.peoples.it

    The pin n°16 (RGB EN.) works but it seems that my TV merges the RGB signal from my Matrox with the TV signal from the antenna.
    I need for a schematics to connect my Matrox via the croma and luma signals (do you know if I've told a &$!%!! ???).
    Thanx again.

      Hi

      I would just like to point out that there are a number of different types of RGB. Normal VGA equals RGBHV (progressive scan video with separate horizontal and vertical sync). Then there is a type of RGB usually used on older and/or cheaper front view CRT TV'sets wich expects interlaced video (480i) with a scaning freq. of max ~15.75 kHz.
      When connecting VGA to a TV, the RGB input has to be named as "progressive scan compatible" or something similar and it must also support a scaning freq. of at least 31.5 kHz (wich is what is required for displaying progressive/non-interlaced 640x480@60 Hz, known as 480p).
      One very nice feature of the G400 is it's capability of doing custom video timings, resolutions and refresh rates, (use PowerStrip,PowerDesk and do a LOT of reading over at http://www.avsfoum.com before trying...).
      When the horizontal resolution is increased, (to 720x480 (native DVD, non-squared pixels), or 848/856/864x480 (squared pixels,true 16:9,makes Windows desptop look good/unstreched), the horizontal sync signal gets shorter and the picture usually gets narrower. But thanks to the G400 you can lengthen the sync signal to get higher horizontal resolution @ video timing identical to 640x480. It's usually the CTR-tube that limits the maximum usable horizontal resolution.
      Also, to prevent damage, don't go any higher on vertical resolution and refresh rate than 480 pixels and 60 Hz if your TV set don't sync on more than 31.5 kHz.

      Unfortunately i have not used "SCART-RGB" on my G400/TV-set combo, so i don't really know what type of RGB it outputs. I'm sure someone else at this forum will be able to tell.

      I understand that you would like to use a 13 year old TV, is that correct? If so, it is unfortunately unlikely that it will handle 480p.
