Almost all nVidia based cards are supported from TNT-1 to GeForce FX. (The support of other vendors like S3 or ATI is not planned so far!)

For cards with the integrated TV chip 'MV' there are some features not integrated yet. For example the selection of the TV standard NTSC or PAL has to be done manually in the driver so far. The main functionality of TVTool is available of course.

The card with the TV chip on it must be set to primary in the bios of the PC. Otherwise TVTool can´t detect the TV chip. In the bios you will find the option: VGA boot device. If the TV chip is located on the PCI card you have to select PCI here. The system will then boot on that card, so you should connect your monitor to that card.

Version 8 or greater: BT868, BT869, CX25870 - 25875, CH7003 - 7008, SAA7102, SAA7104 (A), SAA7108 (A), MV (NV17)

Version 6.0 or greater: BT868, BT869, CX25870 - 25875, CH7003 - 7008, SAA7102, SAA7104 (A) and SAA7108 (A)

Version 5.5: BT868, BT869, CX25870, CX25871, CH7003 - 7008

I recommend cards with the CX25871 TV chip from Conexant. This is the most capable chip at the moment and offers the best TV quality. I can´t say on which cards it is found definetely, as most manufacturers don´t use a certain chip. So you should check it out at your local dealer. As far as I know Hercules cards always come with this chip, also the ASUS 7100 pro/TV (MX400) seems to have it. Also the GF4 Ti 4200 from Pixelview uses the CX25871 (all without guarantee).

(without guarantee).

Note: Frequently it is asked if this statement is still up-to-date. So here the confirmation: The CX25871 is still the best TV chip and should be first choice when investing in a new graphics card!

The horizontal frequency produced by the graphic card is different for each size adjustment. Most monitors are not able to produce a picture at every frequency. So it is possible that you have a blank screen or a flickering picture at certain size adjustments. For example the Sony CPD-420GS monitor works at these modes:

The easiest way is to go to the display properties. Click with the right mouse button on the desktop, then -> properties -> adjustments -> more options -> GeForce 2 GTS (resp. your card). The point 'TV encoder type' shows the chip used.

The internal TV chip of the GF4-MX cards has the label NV17.

If there are more than 1 graphics cards in you system then the card with the TV-Chip must be set to primary in the bios of the PC. Otherwise TVTool can´t access it.

Special case: Viper 550 and Leadtek S320

On these cards the same lines are used for the monitor and the TV chip. In conjunction with some monitors it can happen that the communication with th TV chip is not possible anymore. In these cases go to the hardware detection of TVTool and select the address 2 manually. Then it should be possible to use TVTool and to activate the TV mode. But the connection detection will probably not work correclty.

Another possibility is to cut the DDC lines in the monitor VGA cable. I recommend to buy an extension cord for the VGA cable. Then you cut the DDC pins at the VGA connector of this cord. You find the pinout in the monitor manual. Then TVTool will run properly. The only drawback is that Windows can´t detect your monitor type anymore. But in most cases this is not a problem as you can adjust this yourself (maybe better thatn Windows).

Since version 7 the GF2Go is supported. Exception:Overlay windows might tremble. We are working on this problem. Until it is fixed please disable overlay funtion in the player software. (Version 8 will have a fix for that!)
