I Need Help With Graphics Card And TV

I used to have my Samsung HD TV as my computer screen, and its worked fine for about 6 months now, today i just installed my new graphics card, and its stoped working.. i connect it to the tv and you can see the windows loading sign, after that has loaded the screen goes Black, then goes Not Supported, it usualy says that if its not connected. I connect it to my nourmal PC screen and it works fine, so i have no idea whats going on here.
No idea why it does this please help!

Answer #4
its called NVIDIDA Geforce2 MX/MX 400
THAT’s a more improved one
MX400 is a verry low end card
what’d you have in there before ?
anyway
that card may not read what resolutions or refresh rates the TV supports
think that’s a pre-LCD-TV card
try setting the refresh rate to 60Hz on the PC screen then try it
