fun with xorg TV Out

downbound010 · 04-04-2006, 12:42 PM

Ok, I'm going to give in and ask. .

I've got a Asus V9400-X/TD/64m (basically a Nvidia GeForce 4 MX 4000) it's got Composite TV Out.
I've got a pansy lil 800x600 max resolution generic monitor (yea, I can get this to work)
I've got a big ole 42" RCA Rear Projection TV with Composite IN (P52750WK)
OS CentOS 4.2
Default Nvidia Drivers:
nvidia-graphics8178

I would LIKE to set up a clone view with both of these so they show the same output. Though, I'm pretty sure that requires they run the same resolution so I'm willing to skip that. What I'd really like is to output to that big ole TV. I just can't seem to get it to work. I'm in the US so the format SHOULD be NTSC-M. I've tried a bunch of things. Anyone want to lend a hand, maybe someone's done a xorg.conf file for a big projection TV before.

I'm closer now. . I got twinview to work on BOTH. . . With a lil help from the search function. (sorry, didn't see it the first time. Now, who wants to help me work on some cloning?)

Yes they do need to be set same resolution or you will miss some part of the picture.

One problem I found is that setting composite out doesn't work with nvidia drivers - it seems to switch off twinview altogether. At least that is the case with my MX420. In the end I had to buy an svideo-scart adaptor and use that to get any sort of picture at all. Perhaps you have something like a vcr that accepts svideo that you could run the signal thru first?

Here's my xorg.conf parts:

(I don't recall if you actually need separate monior/screen sections, but I left those in after experimenting with xinerama I think)

I figured it out. Can't do cloning. Just played with the config a bit and got it going. I'm still not able to get better than 800x600 on the big TV though. I don't know, maybe that's a composite limit??
