TV-Out in ATI fglrx drivers

Cerebral · 2005-09-17 04:37:38

( Hope this is in the right forum subsection... )

I'm trying to get fglrx set up to do TV-out. What I'd like is clone mode (same picture on monitor and tv), with my monitor at 1280x1024 and my TV at 800x600 or 640x480, so that I can play videos on the TV.

My problem: In the two "Clone" modes fglrxconfig supports, it doesn't quite work.
In Mirror mode, both the TV and my monitor are forced to the same refresh rate/resolution -- obviously one of the two (usually my monitor) looks like crap. However, videos play fine on the TV.
In "Clone" mode, my monitor looks fine at its native res, and the TV seems to be at 800x600 or 640x480, but instead of resizing the content, it sets up a virtual desktop of sorts on the tv screen -- as the mouse pans around, the desktop moves under it. As an added annoyance, videos don't show up on the TV in this mode (all black.)

Dual-head mode works as expected, except that there's the problem that it obviously doesn't exactly clone my primary display -- they're two entirely seperate desktops.

I'd rather avoid dual-head if possible, as clone mode would be ideal. I searched the Wiki to no avail; does anyone know how I can set this up?

Thanks!

Did you find an answer? I have the same problem as for the tv-screen is virtually larger than the physical screen. It really pisses me off. I have written xorg.conf a dozen time tonight. Nothing.

I couldnt find much specific info on seacrh engine neither.

Actually, I gave up on having an exact clone, and thinking about it, I'm not really sure what I expected - how does one have the exact same desktop at two different resolutions and expect them to act the same?

Anyway, what I have set up now is a 'wide' desktop - one half on my normal monitor, the other half being my TV. I just drag movies from one half to the other then fullscreen them - works pretty well. I'd give you my Xorg.conf, but my motherboard died two days ago and I'm waiting on a replacement.

You got a point there. Exactly the same couldnt work for having an additional display that is a tv. Perhaps it's the driver's fault. I find it awkward that not more people have this problem (which is good)

And thanks for the offer. Too bad about your motherboard.

Can I get your xorg? I'm having the same problem

Yeah, here's my current Xorg.conf. I switched recently to a dual-head setup, as changes to my setup have made it a more preferable way of doing tv-out.
