And also not to forget the gamecube can't output progressive as no games support and it neither does the boot menunot even on a NTSC cube.
I have a ton of games that when they boot they ask if I want to display in progressive mode on my Wii. Its software side, so the GC has to support progressive scan through the NTSC component cable.
Oops I mean the PAL gamecube doesn't suport progressive output with pal resolutions so no 576p only 480p and since all PAL games are 576i they will never work in progressive mode. So that's why if this screen works with rgb 15khz we would not need the component cable and we could use PAL gamecubes in full rgb 576i/480i which is a good as it gets if you don't plan on forking out $100 for a component cable.
Also @XCVG RGB output needs a C sync to work properly. NTSC consoles don't even have RGB output not even with the component cable. The component cables takes the raw YCbCr signal and converts it into either RGBHV 30khz or YPbPr. VGA does not work with 15khz in this case. Also this screen doesn't support component (the chip does but again it is not programmed to accept it)
The NTSC av chip outputs composite and S-Video as standard through the av port which are both 480i signals. The PAL av chip outputs compsite and RGB and are both 576i signals.

I have also been in contact with the supliers and they have also told me that this screen doesn't support 15khz rgb. Only 30khz vga and composite.
