OT - 1080i and nVidia
OK, I can't figure this out... I've got an nVidia GeForce 7300 GS, and a Sceptre Komodo X32 HDTV which is capable of 1080i, and I've got a DVI to HDMI converter cable... so WHY is it when I hook everything up, the picture looks horrible and grainy and stretches off the screen?!? Is the 7300 GS just incapable of such a high resolution? I doubt that's it, though, as if I set it to 720p, it STILL looks horrible, even though the TV can handle that same resolution through the VGA port! Anyone know WTF is going on here or am I a complete idiot? I've searched all over the web and everyone seems to be having this problem but no one knows how to solve it...

Re: OT - 1080i and nVidia
Perhaps it's a matter of refresh rate?

Re: OT - 1080i and nVidia
LCDs don't have a variable "refresh rate" to worry about.
Ekolis:
Are you certain that the converter cable is not a piece of junk? Do you have a different PC to check the TV's input with, to rule out as much as you can?
The 7300 go in my laptop can output 1900x1200 (as well as 1080p) without trouble over VGA, so it isn't the card (barring any freak silicon accidents).

Re: OT - 1080i and nVidia
I don't have any other PC's with DVI output to test this with... I asked over at the nVidia forum and someone there said that this is caused by the 7300 not supporting HDCP or something, and that I'd need to get an 8000-series card for it to work, but then I've heard of people having trouble with those as well...

Re: OT - 1080i and nVidia
Today I tried it under Ubuntu, and it wouldn't give me any higher resolution than 720p... I guess my video card just doesn't support that resolution... a 7300go might actually be better than a 7300GS

Re: OT - 1080i and nVidia
HDCP is only an issue if you are trying to play AACS protected content (an unprotected path downgrades the resolution to 480p IIRC); lack of support for it will by no means prevent you from using a particular resolution normally.
