Under Linux you have two methods to get G400 TV out working:
</p><div class="important" title="重要" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">重要</h3><p>
for Matrox G450/G550 TV-out instructions, please see the next section!

    Using the driver and the HAL module, available from the <a class="ulink" href="http://www.matrox.com" target="_top">Matrox site</a>. This will give you X
    on the TV.
    </p><p>
    <span class="bold"><strong>This method doesn't give you accelerated playback</strong></span>
    as under Windows! The second head has only YUV framebuffer, the
    <span class="emphasis"><em>BES</em></span> (Back End Scaler, the YUV scaler on
    G200/G400/G450/G550 cards) doesn't work on it! The windows driver somehow
    workarounds this, probably by using the 3D engine to zoom, and the YUV
    framebuffer to display the zoomed image. If you really want to use X, use
    the <tt class="option">-vo x11 -fs -zoom</tt> options, but it will be
    <span class="bold"><strong>SLOW</strong></span>, and has
    <span class="bold"><strong>Macrovision</strong></span> copy protection enabled

    Using the <span class="bold"><strong>matroxfb modules</strong></span> in the 2.4
    kernels. 2.2 kernels don't have the TV-out feature in them, thus unusable
    for this. You have to enable ALL matroxfb-specific features during
    compilation (except MultiHead), and compile them into
    <span class="bold"><strong>modules</strong></span>!
    You'll also need to enable I2C and put the tools
    <span class="application">matroxset</span>, <span class="application">fbset</span>
    and <span class="application">con2fb</span> in your path.
    </p><div class="procedure"><ol class="procedure" type="1"><li class="step" title="步骤 1"><p>
      Then load the <code class="systemitem">matroxfb_Ti3026, matroxfb_maven, i2c-matroxfb,
      matroxfb_crtc2</code> modules into your kernel. Your text-mode
      console will enter into framebuffer mode (no way back!).
    </p></li><li class="step" title="步骤 2"><p>
      Next, set up your monitor and TV to your liking using the above tools.
    </p></li><li class="step" title="步骤 3"><p>
      Yoh. Next task is to make the cursor on tty1 (or whatever) to
      disappear, and turn off screen blanking. Execute the following
      commands:

      </p><pre class="screen">
echo -e '\033[?25l'
setterm -blank 0</pre><p>
      or
      </p><pre class="screen">
setterm -cursor off
setterm -blank 0</pre><p>

      You possibly want to put the above into a script, and also clear the
      screen. To turn the cursor back:
      </p><pre class="screen">echo -e '\033[?25h'</pre><p> or
      </p><pre class="screen">setterm -cursor on</pre><p>

      Change <code class="literal">640</code> and <code class="literal">512</code> if you set

TV output support for these cards has only been recently introduced, and is
not yet in the mainstream kernel.
Currently the <span class="bold"><strong>mga_vid</strong></span> module can't be used
AFAIK, because the G450/G550 driver works only in one configuration: the first
CRTC chip (with much more features) on the first display (on monitor),
and the second CRTC (no <span class="bold"><strong>BES</strong></span> - for
explanation on BES, please see the G400 section above) on TV. So you can only
use <span class="application">MPlayer</span>'s <span class="emphasis"><em>fbdev</em></span> output
driver at the present.
</p><p>
The first CRTC can't be routed to the second head currently. The author of the
kernel matroxfb driver - Petr Vandrovec - will maybe make support for this, by
displaying the first CRTC's output onto both of the heads at once, as currently
recommended for G400, see the section above.
</p><p>

On other cards, just use the <a class="link" href="vesa.html" title="6.13. VESA - output to VESA BIOS">VESA</a> driver,
without VIDIX. Powerful CPU is needed, though.

First, you MUST download the closed-source drivers from
<a class="ulink" href="http://nvidia.com" target="_top">http://nvidia.com</a>.
I will not describe the installation and configuration process because it does
not cover the scope of this documentation.
</p><p>
After XFree86, XVideo, and 3D acceleration is properly working, edit your
card's Device section in the <tt class="filename">XF86Config</tt> file, according
to the following example (adapt for your card/TV):

</p><pre class="programlisting">
Section "Device"
        Identifier      "GeForce"
        VendorName      "ASUS"
        BoardName       "nVidia GeForce2/MX 400"
        Driver          "nvidia"
        #Option         "NvAGP" "1"
        Option          "NoLogo"

The NeoMagic chip is found in a variety of laptops, some of them are equipped
with a simple analog TV encoder, some have a more advanced one.
</p><div class="itemizedlist"><ul class="itemizedlist" type="disc"><li class="listitem"><p>
  <span class="bold"><strong>Analog encoder chip</strong></span>:
  It has been reported that reliable TV out can be obtained by using
  <tt class="option">-vo fbdev</tt> or <tt class="option">-vo fbdev2</tt>.
  You need to have vesafb compiled in your kernel and pass
  the following parameters on the kernel command line:
  <tt class="option">append="video=vesafb:ywrap,mtrr" vga=791</tt>.
  You should start <span class="application">X</span>, then switch to console mode
  with e.g.
  <span class="keycap"><b>Ctrl</b></span>+<span class="keycap"><b>Alt</b></span>+<span class="keycap"><b>F1</b></span>.
  If you fail to start <span class="application">X</span> before running
  <span class="application">MPlayer</span> from the console, the video
  becomes slow and choppy (explanations are welcome).
  Login to your console, then initiate the following command:

  </p><pre class="screen">clear; mplayer -vo fbdev -zoom -cache 8192 dvd://</pre><p>

  Now you should see the movie running in console mode filling up about
  half your laptop's LCD screen. To switch to TV hit
  <span class="keycap"><b>Fn</b></span>+<span class="keycap"><b>F5</b></span> three times.
  Tested on a Tecra 8000, 2.6.15 kernel with vesafb, ALSA v1.0.10.

  <span class="bold"><strong>Chrontel 70xx encoder chip</strong></span>:
  Found in IBM Thinkpad 390E and possibly other Thinkpads or notebooks.
  </p><p>
  You must use <tt class="option">-vo vesa:neotv_pal</tt> for PAL or
  <tt class="option">-vo vesa:neotv_ntsc</tt> for NTSC.
  It will provide TV output function in the following 16 bpp and 8 bpp modes:

  to a different resolution to activate TV out. If you can see an image on the
  screen in 640x480 or in 800x600 but not in 320x240 or other smaller
  resolution you need to replace two tables in <tt class="filename">vbelib.c</tt>.
  See the vbeSetTV function for details. Please contact the author in this case.
  </p><p>
  Known issues: VESA-only, no other controls such as brightness, contrast,
  blacklevel, flickfilter are implemented.
