Ecco la risposta che ho ricevuto dal customer care europeo sui problemi
della tv out della mia radeon 9700, sopratutto per i bordi attorno
all'immagine tv, non sono ancora riuscito a capire come risolvere, il testo
è lungo,eccolo:
Dear Customer,
Thank you for contacting ATI Technical Support.
Based on our experience, TV output issues are usually due to system
configuration errors and we believe that following the steps could solve
your problem.
1. Television output control is "greyed out" and cannot be selected:
http://www.ati.com/support/infobase/3056.html
2. To output the computer display to the TV or VCR
For recording purposes, you will want to play your video file Full Screen
and enable TV out. If you would also like to output sound from the computer
to the TV, then please visit
http://support.ati.com/http://www.ati.com/support/connectors/common/connectt
voutaudio.html for details on how to attach the cables correctly, maximum
resolution
    Ensure that you set the maximum resolution to a value of 800 X 600, as
that is the maximum resolution a television will support. If your desktop is
set to a higher resolution, you may experience a "virtual desktop" - screen
size is larger than the actual screen size and the mouse is needed to scroll
around to see everything. To eliminate this, either disable TV out,
disconnect the TV, or lower the resolution to a maximum of 800 X 600.
3. Black borders around picture on TV screen.
This symptom may occur with TV SETS that have picture SIZE controls that are
adjusted to extremes. Adjusting the TV controls should resolve the problem.
If the problem persists you can determine if the problem lies with the TV
SET, as follows;
  ·       Connect a VCR to the TV using the composite or SVIDEO cable.
  ·       Play a movie on the VCR.
If the movie also displays a border, then the TV SET must be adjusted - if
possible - so that the movie actually fills the screen.
4. Black and white picture using tv ouput with a TV set.
This symptom may occur if:
1. The TV output is set to an incorrect country standard.
To ensure that the correct Country Standard is selected please do the
following:
Go to Start, Settings, Control Panel.
Click on the Display icon.
Select the icon DISPLAYS.
Please ensure that your television is connected, activate the TV OUT button
and click on Apply.
Please Double click on the TV Button to enter into the Setup.
Click on FORMAT.
Under " Select By Country", please ensure that your country has been
selected.
Click on Apply.
You can check the Format ie. the TV country standard by re-entering into the
setup as before.
2. You are using an S-vhs cable plugged into a Scart adapter:
if you are using such a cable, please connect it directly into the TV set.
If you do not have an option to directly connect your SVHS cable into the
back of the TV, then you will have to use a Composite cable with the scart
adapter. If your card only has an S-VIDEO connector, you will need the
S-VIDEO to Composite converter cable 7900:

5. No TV display connecting TV out through a VCR.
Whenever possible, eliminate the VCR from the circuit by connecting the TV
directly to the graphics card - not all TV's have the required connectors.
This will establish whether TV out is functioning appropriately. If it is,
re-connect the VCR and proceed.
  ·       Check the VCR for an "input select" function or switch.
  ·       The VCR MUST be configured to accept a signal from an external
source, i.e. the input jacks rather than its own internal tuner.
  ·       In some cases, the switch will be available on the front panel of
the VCR, in others, the remote control will be required. In some - rare -
cases, the VCR may need to be in "record" mode in order to accept a signal
from an external source.
  ·       The TV must also be configured to accept a signal from the VCR. In
some cases, this means tuning to channel three. Some TV's have a dedicated
"video" mode, accessible from the front panel or the remote control.
For additional information, refer to the Owner's Manual for the VCR and the
television. If problems persist, experiment with some OTHER "known good"
source of video, such as a camcorder, to make sure you can get a signal from
the input jacks on the VCR to the TV screen.
6. If movies appear BRIGHT and then DIM.
. while watching DVD on a Television, please visit
http://www.ati.com/support/infobase/3095.html
 for detailed information on
this issue. This is not a limitation of ATI graphics cards.
7. No TV OUT tab in DISPLAY PROPERTIES.
Your problem is a known issue with Rage 128/128 PRO products and driver
versions higher then 4.12.xxxx. The problem does not occur in all system
configurations.
To workaround the issue, completely uninstall the current driver and install
driver 4.12.6292 or older under
http://www.ati.com/support/products/pc/rage128/win98/rage128win98previousdri
vers.html
8. Wide screen TV OUT resolutions.
848*480 is the only 16:9 display mode available on Rage 128/128 PRO.
848*480 and 1920*1080 [90hz - 21''+] are the only 16:9 display modes
available on RADEON cards.
If you calculate 16:9 = 16 / 9 = 1.77777777. In relation to screen
resolutions, this means:
848 / 480  = 1.7666666667 and 1920/1080 = 1.777777778 which should be close
enough.
The complete list of resolutions depends on the driver version and operating
system. NOTE: that resolutions are limited by the performance of the
attached monitor.

 Er televisore.
Allora da bravi furboni quelli della ati hanno dato la colpa ingiustamente
all'televisore, visto che con l'altra scheda (nvidia) e lo stesso tv
funzionava perfettamente in overscan.
