I have already tried some versions of 3dfx tools but none worked for video overlay.
I think the problem is the driver. I believe that even the 3rd party driver makers are focused on the game thing and did not enabled the video overlay option.  


Dou you know any 3rd party tools that can control that ?

Hi,

I have a  Vodooo 3/3000 video card and was using a WIN98 with original drivers and it was ok.

I upgraded my o.s. to WIN2k and installed the original drivers for WIN2k. After that the settings for  Video Overlay (inside 3dfx Tools > 3DFX Color) are in grey . (they are not avaiable)

Besides that, in Monitor Type ( Control Panel - Display Properties - Settings -Advanced) appears a "Generic Television" (in win98 there wasn't that) and my monitor CMC-1703b. It seems that this card was set up for two video monitors. And the Generic Television is the primary one. I have tried but could not change it to secondary one.  

I reformatted my HD and after reinstalling O.S., I installed AMIGAMERLIN 2.5 SE FOR voodoo3/4/5(tm) Driver kit but the same problem remains.

Why does this Generic Television appear ?
Why video overlay option is not enable ?

I usually watch DVDs in my computer and I use these festures to adjust the color and brightness.  


Thanks for any help.
