Bought new video card to fill screen, still doesnt, plz help

[poof]

I bought an nvidia 8400 GS (http://www.newegg.com/Product/Product.aspx?Item=N82E16814500093) for my 50" HDTV because my onboard video wouldnt fill the entire screen and the 8400 fills the same space, i dont know what im doing wrong. Its vga to vga (the tv doesnt have DVI or HDMI, just s-video, vga, and composite/component). Im using vista 32 + the latest drivers and it wont let me change the resolution past 1360x768, im not sure what else to do, any ideas?

update: I plugged in composite through the s-video to composite adapter that came with the card and it will only do 1024x768 @ 30hz but fills up more than the screen and looks terrible, and im concerned that having it at 30hz will damage the tv. This doesnt make any sense, the card can handle 2048x1536.

What model is the TV? You say it won't let you change the resolution past 1360x768, that might be the native resolution of your screen. If that's the case, you just need to adjust the over/underscan settings to be 0.

1360x768 is most likely the native resolution of your TV, as mentioned above. The problem sounds like a setting on your TV, not a computer/GPU issue.

It might be a video driver setting too. When I hooked up my new HTPC to the TV, it wasn't filling the screen either. Calling Vizio yielded zero help, and finally, I found some setting in the ATI driver thing (like Nvidia control panel but.. ATI) that let you change over/underscan. Once that was set to none, it filled the screen and worked fine.

it cant be an HDTV if it dont have some type of digital input... whats the model on the tv?

Sure it can. Many of the early ones didn't have DVI or HDMI. I think Rainless has one of those clunkers.

The first HDTV's were probably 720P, and max resolution of 1366x768 which seems what yours is. You need a better TV, it is not the graphics card. I am using my 32" atm at 1920x1080 fine...

Please. He should be able to run it perfectly fine at the correct settings.

Maybe its doing that so it doesnt stretch? Could you take a picture of the screen so we can see how it doesn't fill the wholes screen?

ratbuddy already pointed out the correct problem

It is over/underscan

I believe it is actually the TV's fault but the problem has existed for so long that now even intel IGPs include the option.

Man that TV is old (or should I say VERY early HD). You say the TV has component inputs so use them (720P max on component) as you have no HD capabilty at all using analog, S-VGA or composite inputs. You also have no HDCP capability either so forget anything over 480i when trying to view HD anything from Vista.

A 1360x768 resolution on a 50" screen is going to look lousy with any input other than component.

No HD over VGA? How ya figure? Need to know the model of TV before making that assumption.

[Badbonji]

I believe there is an option in the nvidia control panel which allows you to change the size of the picture, or also you should be able to change the aspect on the tv too. I have to set mine from normal to "Just" or something like that, and it fills the screen up perfectly...
