nvidia 6800 HDTV timings/overscan question

509 Views 3 Replies 2 Participants Last post by  JDLIVE
I switched to MCE2005 and an nVidia 6800 for my new HTPC. With the latest drivers, I can get my Sony HS10 to accept a 1080/24PsF signal. Of course since the native resolution is 1368x768, the desktop is too large to be useful and full screen apps have a large part of the display off the screen. I have tried using the nVidia overscan correction utility, but it doesn't seem to have any effect. I also tried the NVkeystone correction, which I read might allow the desktop size to be adjusted, but it just gave me a garbled display. The display also seems to be off-center a bit. Tried using Powerstrip to adjust the size, but it seems to just cause me to lose sync with any adjustments. I have the HS10 on the DVI port and an analog LCD on the VGA port, using dual display mode.

Any suggestions, or should I just go back to the native 1368x768 with the 56Hz refresh timings?

Powerstrip has a feature where you can resize your desktop while maintaining the same timings (they call it the custom resolution designer). I suggest you try it.

Beginning with Build 480 of PowerStrip, a new, simple resolution "designer" is included that may ease the tedium involved in eliminating overscan. You would typically begin from the manufacturer's recommended but overscanned resolution and timing (e.g., 1280x720p), and, after ensuring the result is indeed sharp (albeit overscanned), you would access the designer from the PowerStrip custom resolution page (there's a little speedbutton above the Close button).

1. PowerStrip menu > Display profiles > Configure

2. Switch to the manufacturer's recommended resolution

3. Click Advanced timing options

4. Center the image on the display using the position controls; TVs are designed to overscan, so do not try to adjust the screen size using the size controls

5. Click Custom resolutions

6. Click the "designer" speedbutton above the Close button

7. Size and position the designer window so that it stretches edge-to-edge, keeping in mind that the window will snap to values that the hardware can handle (e.g., the horizontal resolution will usually need to divisible by 8).

8. When you are done, click Ok to return to the Custom resolution dialog box and click "Add resolution", then follow the instructions on screen.

With any luck, the result will require only a tiny bit of fine-tuning in Advanced timing options.

Thanks, I'll give that a try. I assume that is the beta version?
OK, got this working after some fiddling (make sure you're working on the primary display!). I did get the desktop to fit, but what scaling is happening to make this work caused some pretty bad artifacts to show up. And MCE seems to ignore the desktop, anyway, maybe that is the norm for renderless players. So it looks like I'll be going back to my native res and forgetting about 1080/24PfS until I have a native 1080 PJ. ;)
