Component input=blue picture
I have just finished building a new Home Theatre PC using a slimline Hiper chassis. I want to connect it to my Toshiba 32" CRT Picture Frame3 TV using the component input sockets. But when I do this the picture ends up very very blue. Its not the cables as when the PC is booting the WinXP logos are in full colour and look fine.
I've looked in the nVidia display setting options for the TVout adjustments but I can't find anything that helps. There only seems to be a choice of composite or S-Video. The S-video o/p works OK but I wanted to see if there was an improvement to be made in picture quality using the component input. Theory 1 - The MOBO is sending S-Video siginals down the component inputs and somehow needs to be set to component (I think this is possible). Theory 2 - The MOBO is sending out HD component which isn't compatible with my CRT. Any other theories? Andy |

when you say very blue, is that as in you are getting a picture/signal but the display is shading blue, or the screen is blank and blue in colour?

Well, I've connected the component ouputs from the back of the PC to the component inputs on the back of the TV. Nothing else. So there's something coming out of the PC into the TV! Strangely though, as I metioned earlier all looks fine until the WinXP desktop loads and the picture goes blue!

Generally I've never had any luck with TV outputs on PC's, usually (rather like you) they work while booting up in (or in DOS) but as soon as Windows loads you lose it. |

Would the resolution make a difference on a CRT? Plus the S-video input works fine at 1024x768 & 800x600.

With my NVIDIA card, however, it seems to think you've got a HDTV connected if you use component. Presumably your TV doesn't accept HD so make sure in the driver you have 576i selected not something like 720p. I'm not sure whether it would always try to output a widescreen resolution though even with 576i, which your TV wouldn't be able to handle. The bootup screen works because at that point it's working in a "safe" mode. But if you're getting a stable picture OK, it's just that it's blue, then I don't really know... |

That does make sense though, I do remember a page with loads and loads of selections for different countries listing PAL standards galore and resolution settings. Maybe the resolution is the problem after all (but for slightly different reasons.)Thanks for that, I will have another play later on. Probably another late night coming on! Andy |
