[mythtv-users] Twinview CRT + TV and Domain panning

Thanks a lot guys. As I told Tom that's the kind of "been there done that (or couldn't do that) I was looking for.
 
I'll just go for side-by-side (right-of instead of clone) displays, hopefully getting different screen resolutions working properly; or via setting up two screens in X like Tom pointed out.
 
Chris: About that P4 3.0Ghz, I'm intrigued because this is the machine I'm using for Myth (front + backend). With a Nvidia 6600GT (AGP) and a Gig of Ram. At the moment I only have SD, but planning to go for HD this fall (with proper capture card that is). Question is: is the machine going to keep up ? (Because you said you ditched the setup. Do you still have the P4 as a backend of something ?).
 
Best regards,
 
Francis

1) Have my CRT and the TV working at the same timeand2) Have two different resolutions: CRT at 1280x1024 and TV at 1024x768 (I know I put 1024x768 and 800x600 in the first post, I only choose those to test things out.) I know I might have to set up 2 screens in xorg.conf, but it looks like twinview can achieve this, from what I could read. But actually never saw a confirmed case.
OK.  I actually spent quite some tiem trying to get this same thing working a year or so ago without any luck.  I had a single frontend that was connected to an 19" CRT monitor in my office and a TV in my living room.  I wanted to be able to watch TV in either location at anytime, but I wanted them to simply mirror each other because I onmly had the one frontend at the time and the rooms were contiguous. Where it got tricky was when I ran into your problem - I wanted to be able to watch my HD content at native resolution on my monitor while having it simultaneously downscaled and mirrored on the TV.  I was never able to accomplish my goal of having the HD picture mirrored on the TV - the closest I came was setting my VGA monitor to 1280x1024, while the NTSC monitor was a 1280x1024 virtual desktop on a 1024x768 device with picture centered so with HD content you would get the full vertical picture with the sides cropped.   If I remember correctly, at least one of the reasons I ditched that setup was lack of CPU when playing back 1080i content  - this was a 3.0ghz hyperthreaded P4  and an nvidia 5200 graphics card.Anyhow, best of luck to you, and please report back if you are successful!  -- TV/IT EngineerWCJB-TV Gainesville, FL(352) 377 2020 x248cribe at wcjb.com
