According to the picture above and this write-up ( Google translation) up to 3 (maybe even 6!) PS2s & monitors can be connected via system link and strung together to produce a striking panoramic display for single-player racing—call it, "multiple monitor mode". Of course, you'll need to get your hands on 3 PS2s, TVs & copies of GT4, plus LAN hardware…
[Thanks, Lok… got a PS2 we could borrow?]
