Default TV positioning and flickerfilter request

Hi, thanks for getting overscan working in the latest drivers.

Two other things would be very useful: positioning the image on the TV, and the adjustable flicker filter (both as seen under win98).

Ideally, could you make the flicker filter dynamically adjustable? I can definitely think of situations where I'd want to have it on and also others where I'd like it off... and I don't want to have to restart X. An additional IOCTL interface on the /dev/nvidiaX device would be just great (this would also mean it is controllable outside of X).

Anyway, keep up the good work!

Is there any way to adjust this flicker filter now? Or something to remove the flickering on TV screen?

TIA

NVTV (can be found on sourceforge) can control some of this. It seems to have problems with my dualhead card, but I'm sure that's not the case with all.

Give it a try. You can resize, change flicker, you name it.

Thanks for a quick answer!!
Unfortunately, I have tried NVTV already. Sometimes it recognizes my tv-out chip (as Chrontel), but rarely. Some of the tabs work, but the most (and the one with the "flicker" slider) not - no matter what chip it sees. When NVTV recognizes my chip, it allows me to view and change some registers (NV Regs and Chrontel Regs). Should I try to get the names of these registers so you could say which one could possibly be for flicker filter adjusting?

I don't have a clue what controls what, to be honest. Your best bet is to try the NVTV help forum or mailinglist.

You can find it through google...
