Hello all. How can I tell if my telly (an el cheapo Grundig 28" widescreen I bought for the spare room for my nephews to play videogames on when they come down on the weekends) is really displaying RGB? Although the picture does improve when I switch from using the a composite cable to using an Ixos (PS2) RGB cable the telly doesn't autoswitch to AV1 RGB - it stays on AV1 and also the 'sharpness' option remains available in the tv menu - same using different RGB cables on different consoles. Of course when I do the same thing on my 100HZ Tosh the sharpness option is disabled and it auto switches (as it does on my standard 50hz sony) The thing is when I manually switch from AV1 to AV1 RGB there is no difference in the display The manual is crap - doesn't even mention RGB AT ALL,but at least its only a couple of months old so its within warranty if there is a fault. If anyone has any ideas let me know,the chap in my local Dixons,although very nice, didn't even seem to know what RGB was exactly(and told me I'd get a better picture with s-video - even though the grundig doesn't have s-video input anyway!),but after checking he came back and told me that yes - one of the scart terminals was RGB so I dont know what to think..... Any ideas?
