Default switch between monitor/tv quick

Hello. i have been struggeling alot with the tv-out in linux.
And now i'm i have kinda given up.

I am doing this.

Section "Device"
Identifier "Card0"
Driver "nvidia"
VendorName "NVidia"
BoardName "Geforce 4 MX"
Option "NvAGP" "1"
Option "TwinView"
Option "SecondMonitorHorizSync" "30-50"
Option "SecondMonitorVertRefresh" "60"
Option "MetaModes" "1280x1204, NULL; NULL, 800x600"
Option "TVStandard" "PAL-G"
Option "TVOutFormat" "SVIDEO"
Option "NoLogo" "true"
Option "TwinViewOrientation" "Clone"

and
Modes "1280x1024" "800x600"

When pressing ctrl_alt_+ it switches off the monitor and the picture comes availible on the TV
But the problem is that the Resolution on the tv does not get 800x600, its somekind of "Zoomed" 1280x1024...
Why?
What i'm i doing wrong?

I cant watch movies in twinview mode because the movie becomes "choppy" on the tv.
Not so fun to Change XF86Config evertime i gonna use tvout either.
Why cant nvidia do a little program for this

Please help me.

I think it is better not to use the twinview, it will disable some features (like video overlay) as well.

Follow the directions for "two X displays" in the README and you can setup the second screen (TV) with the resolution you like.

the problem you are having is that you need the randr extension to work, because your X-server still uses 1280x1024 but only the 800x600 will be displayed, you need to tell the X-server that he needs to resize the desktop for it to work perfectly.

good luck
you can always use nvtv instead to make a portion of your screen to appear on TV. xine also makes use of that.

There are two options:

1. when you start a program you can specify the second display. e.g. when you start from the command prompt:

DISPLAY=:0.1 mplayer filename

This will start mplayer on the second display.

2. you can make the mouse move over to the second display by using the correct configuration section for the Serverlayout, e.g.:

Section "ServerLayout"
Identifier "Layout[all]"
InputDevice "Keyboard[0]" "CoreKeyboard"
InputDevice "Mouse[1]" "CorePointer"
Option "Clone" "off"
Option "Xinerama" "off"
Screen "Screen[0]"
Screen "Screen[1]" RightOf "Screen[0]"
EndSection

With this config, the mouse will move from VGA to TV when you move it past the right edge of the screen.
(assuming your VGA definition is called Screen[0] and your TV definition is Screen[1], names can be chosen differently)

What happens in this config depends on the X window manager that you run. Many windowmanagers will detect that you have two screens and will start two copies, and you will have a taskbar, menu's etc on both screens.
But this is not mandatory, when you use the command line (or a script file) you can start a program on the TV without a windowmanager running there. The advantage is that you have less clutter and no trouble with windowboarders that you need to move out of the way every time.
