DOS drivers for VGA to TV adapter
This page includes information and links drivers which you can use
to make the VGA to TV converter to work with DOS applications.
The driver which are listed in this circuits are for commercial
products (freely downloadable from manufacturer site) and other drivers
are non-commercial (my driver and some freeware drivers).
DOS driver support generally works quite well in standard VGA modes with
most common VGA chipsets (Cirrus, Tseng ET4000, Matrox, Oak, etc).
Note that the drivers need your graphics card to be fully compatible
with the original VGA card. There are many VGA card which claim to be
100% compatible with VGA but my own experience proves otherwise.
It seems that some chipset makers have not implemented some rarely used
VGA features which are absolutely needed by those VGA to Tv drivers.
If your graphics card is not fully VGA compatible then then the
drivers quite propably will not work.
Note to S3 chipset based card users:
None of the drivers seem to work properly on
S3 chipsets.
You might get textmode and some graphics modes to work but
VGA mode 13h 320x200 with 256 colors has not worked on any card tested.
I don't plan to write special drivers for those cards because there are
not enough S3 information freely available and I don't have
S3 based card to test those drivers. If somebody alse has interrests
to write drivers for S3 cards, then contact me.

Tips on using Scitech Display Doctor instead of VGA to TV drivers
Scitech Display Doctor is
a software which allows all kind of configuration to make for VGA card
refresh rates. Theat software can read the screen settings and then use
the saved settings later. It is possible to start Display Doctor,
then start the VGA to TV driver. when you can try to save the screen
settings with Display doctor. If the screen mode is saved successfully you
sould be able to get the same screen settings as the VGA to TV driver
set justs by using the Scitech Display Doctor. Display Doctor allows also
to make adjustments to screen parameters (picture position etc.).
Scitech Display Doctor is not a free software, but you can download
a free evalution version of it to your computer if you want to.
For more information
