I'm having problem using Sony CRT as HD display.

Guys,

Literally, from leftovers (few friends also contributed) I assembled a working PC to be GBPVR stand alone box for my family room TV. The TV set is 5 y.o. 32” Sony CRT (4:3) ,NTSC, that supports 480p or 720p and 1080i formats. I have also HD cable box, (that almost never used as Hi-Def), just regular channels. Cable box connected via RF cable and works great for us. For occasional HD I used HDMI-to-DVI (TV side) cable, but image always has 2 black fields on bottom and upper side as well as two additional side strips if I was watching programs in 4:3 AR. I disconnected TSB from TV and connected PC directly to TV using computer’s DVI-2-DVI cable. I was able to see most of the Windows’ display, but I have those upper and bottom black strips that cover part of desktop image. And it doesn’t matter what resolution I pick on graphic card image on TV becomes smaller or bigger, but those 2 stripes get resized with the image of desktop and covering taskbar with start button and upper side with menus, etc…
Can you give me a clue, where to start? I’m not talking about GBPVR application yet, I just want to use my TV as a monitor and see full Windows’ desktop image.
My graphic card is XFX GeForce 6200 with the latest drivers. The card’s bracket is cut to adapt to low profile case, so it has only DVI output and S-video output (VGA connector is removed). BTW, I tried to connect TV using S-video cable, but card gives no output on S-video connector. Is S-video needs to be enabled some place in settings?

Thanks in advance,
Vlad

The svideo usually needs to be enabled as dual view of some thing of the like. basically you need to tell windows / card's drivers that you want either svideo out only, or svideo / dvi at the same time, running in clone mode.
As far as the tv it sounds like there is an issue with the TV or with that input. It might be a display mode setting as well, maybe something in the menu specifically for the DVI input. You might have to be in the DVI input mode while looking at the menu.

720x480 is the resolution I use on my 36" Sony CRT. If I recall correctly, the TV is detected on the DVI cable as "Sony TV" and you have to enable the option to "treat monitor as HDTV" or something like that. Overscan for the desktop is pretty bad and I have not found any option in the nVidia drivers that will fix this (and I have tried all of them, currently using 94.24). The overscan slider does nothing for me. But while using GBPVR, there are some overscan settings in the config file that you can change so GBPVR fits in the screen just right.

Guys, my sincerely thanks.

As per S-video question, I couldn’t find any “how to enable” reference in NVIDIA software, but eventually found that it’s getting enable if TV is on at the moment I start PC – sort of “auto-enable”.

Torque, I’ll give it another try in 480p mode as suggested. I'm reading about wonder utility called powerstrip. did you tied it?

Thanks again,
Vlad

No I haven't tried power strip. My PVR hardware is dedicated to the TV, so it rarely sees the desktop except during upgrades of GBPVR or the occasional SNAFU. So getting the desktop to fit on the screen quickly dwindled to a very low priority.
