Top and bottom of screen cutoff
Flake:
I'm running 720 x 480 at 480i using component to the TV. However, since the video card is Nvidia I can only use the S-video port's 7-din multipin adapter to component (I think thats what its called). Inside the Nvidia control panel is an option to "resize TV" but it doesnt let me select it - says its not available.
I have messed with the service menu options till I was blue in the face.
On another note, does anyone know if I am just getting S-video PQ in this fashion or is it really upconverting to component quality. I dont think it as it's only set at 480i. Wouldnt component be 480p?

Interesting. So this is NVidia's answer to ATI's DVI to component adapter then.

Svideo is 480i only (or pal 576i). Component could run 480i, 480p 720p, and 1080i. Any resolution you feed it now will downconvert it to 480i.
For the overscan settings, you may have to update your drivers, and make sure that the tv is installed as a tv and not a computer monitor in the driver settings. If it is set to "default monitor" and not "generic television" overscan settings will not show up. Your other option is to google omega drivers and throw those on for testing. Omega has been making awesome custom driver sets for years that unlock all of the options that manufacturers hide. They also have a huge section of tweaks for televisions.
Before you adjust anything in your service menu write everything down.
As far as the service menu on toshiba sets you are going to want to tweak HSIZE and VSIZE ( careful with the vpos setting as I have seen this cause a bug in certain rptv sets that causes one of the main drive chips to burn out). I don't think it will have a effect on direct view sets though. If you are still getting screen cutoff there is always settings burried in the service menu that are blanking settings. Most sets will have something like Hblank ( or top blank-tblank and bottom blank-bblank) and Rblank Lblank. They allow you digitally cutoff the overscan directly to the edge of your screen bezel. If they are set wrong they will cut off the image.
(edit addition) If blanking is set too far away ive seen it cause hazyness in the edges of the picture.

I don't think it's an "S-Video" port. It is a 7 pin port which requires a special cable (although it looks similar to an S-Video port). It is supposed to support HD resolutions.

Hmmmm weird. I have a Geforce 8400 gs and it just has a svideo port. I'm not saying your wrong but the only other model I have seen was that weird s-video looking cable to svideo and composite. Which model of gfx card is it? Like asus,xfx,msi etc?
