I'm currently using my MythTV with a VGA output to my Toshiba 42" widescreen plasma (using the VGA connection). The manual for th TV says that video modes supported are UP to 1024 x 768 on the VGA input. This seems to be confirmed by the Myth box as it "detects" the monitor up to that resolution.

Two questions:

1) When i watch on VGA ouput (even at 16:9 mode) it still only takes up maybe 1/2 of the screen. Do I/Should I mess with the modes or something at this point to get it "right"?

or

2) Do I just get myself a DVI to HDMI convert, plug in the DVI output on the Nvidia card and HDMI to the tv? (There's a big old warning in the TV manual to NOT connect a pc to anything OTHER than the VGA input, but not sure if that's because it'll toast something or because it just won't work--I honestly fail to see why it wouldn't work and NOT harm anything). Anyway, if I plug it into the DVI connection at this point will it "auto-detect" the propery screen size and resolution or must I modify these settings myself?

I have a similar setup but am using a VGA to component adapter (so that I can define my modelines). I also use a DVI to HDMI connection on another one of my frontend machines and it works better that the VGA connection. And yes it should be plug and go...

Just in case you decide to go with DVI to HDMI and it isn't "plug and go" (mine wasn't) I've written up a little info on how I got it all working here:

Well it's sort of plug and go.

Good news is that now I get "full" wide screen at 720p on my Toshiba whereas with VGA it was "stuck" at a 4:3 mode (you could wide screen it, but it wouldn't go the full width of the TV).

The bad news is that when I boot up the system, it gives me a partial screen (where it loads the text Linux stuff). I cannot see the entire screen, so here's what I CAN decipher:

passed an undefined modenumber
Press Return to see video modes

somethinghere (can't read it): cols x rows
some number (can't read it): 80x25
some number 80x50

and so on.

So I'm unable to even use a terminal prompt (I see nothing).

Also, for some strange reason now, when I FF or Rewind at anything other than 3x (like if I pick 5x) the picture gets all pixelated, breaks up, and literally stops FF or RW after about 5 seconds. This is on playback of a previously recorded show.

Makes it difficult to FF through a commercial when you can only do 5 seconds a time (I can try the "skip" but that does it in 1 minute increments and then I have to Rewind 5 seconds a time).

Does NOT do this on VGA mode, for some reason.
