Displaying pc on tv

Ok...this is the first time I cant get it to work.

I have an older 1080I Hitachi or something like that. it is an 1080i tv via component cable.

I have a 8800gt I was trying to hook up to it...no display ever.

Suggestions?

This isnt an hdmi issue I assume as it is a NON hdmi tv and video card...Ugh

Usually, it autodetects on boot. However, if you have a monitor attached as well, then you need to enable it throught the control panel because the video card will assume that the TV is a secondary display. IMO, Nvidia's TV support is lacking.

thats probably what it is...nvidia SUCKING. so, dont have a normal monitor attached and just have it plugged into the tv?

Actually as mentioned, you might have to go into the Nvidia control panel and enable the TV output. As I hook my comp up to the HDMI using a DVI to HDMI cable, it isn't using the traditional TV out. This would be similar to you needing to enable dual monitors, it tends not to be enabled by default. The control panel has something like a wizard for setting it up for your TV, might be something to look at.

You may need boot it with a montior, set up a hot key for enabling the TV output, & reboot. Wait till Windows is going & hot key it.

Yeah I agree that it is probably more complicated than it really needs to be, but it really should be hard. The other outer possibility is that the TV-out doesn't work at all or the TV doesn't know how to handle the signal. I still suggest looking at the Nvidia Control Panel. That would be your best bet.

Are you using the s-video out on the card? dvi-hdmi converter? s-vid to component converter?

I had a hell of a time with an nvidia card sending output to a tv through the s-vid output when I had to convert it to composit. Something about the resistance on the s-video end being used by the hardware to detect a connection and the nvidia driver not wanting to activate the s-video port when it didn't think there was anything attached to it.
I finally did manage to get it to force the detection... but then it stopped working for no apparent reason and I was never able to get it back.

Good luck getting your nvidia card to admit there is a tv attached to it.

It is actually a dvi to component cable.

I might just go and get an ati card.

Hmmm, just another thing to throw out there, make sure the TV is on when you turn the computer on. It won't sense if it's off.

ahh ok I see what you are trying to do now. You aren't using the actual TV out from the video card, just the standard DVI out. It should work no problem on boot, but the TV being on and on the right channel at boot sometimes is needed. It may just be possible the cable you have just won't do the trick. The cable might not be converting the signal properly to be displayed on the TV. DVI is a digital connection after all, while component is analog.

it worked on the last system I did it on...but who knows. I have plenty of other things I can try.

Another thing to keep in mind... if your TV has an input source selector, your computer may not see the TV unless the component is selected as input. I know my laptop is kinda picky about detecting HDMI properly and routing audio to the TV if I plug the cable in while the TV is still "watching" cable.

Don't know if the DVI will be as picky as HDMI though.
