I have a PNY gforce 4 ti 4200 64mb card . I have been
trying for about a year to get my tv out to work.
Yesterday I was looking at a thread that said theres a new set of drivers that will allow you to enable your
tv out . Heres the thread
[had the same problem with my video card. I have Triplex TX-680 which is based on Geforce 4 MX440 AGP8X. I also tried drivers that you did, but then I tried download drivers 42.82 from Guru3Dand my TV-Out worked. There is a special option in those drivers than other drivers don't have (I don't know about 43.00 becasue I haven't checked them yet). After installing those drivers, go to "NView Display Setting", then press "Device Setting" in bottom left corner, then "Select Output Device", then "Advanced", and then click "Check here if you have TV connected but remains unselectable". If It require you to restart PC, do it. After that, your TV-Out function should work.
What Video card are you using (just I want to know )?
Let me know if that worked. Good luck!!!!]
I am using the 43.00 drivers from guru 3d website
And I now have excellent tv out on my tv
I hope this helps someone
