1080i only takes up 16:9

I found the modeline here,
http://www.mythtv.org/wiki/index.php/Modeline_Database

It's supposed to be an ASTC standard.

I tried a "1920x1080" , and it didn't work. Sorry, needed sleep last night. I'll be here till 5:00 EST today.

Beyond that, I think you're likely getting the best that you can.

Thanks,

yeah, xvidtune doesn't seem to do anything. I'll install windows and try that powerstrip software that people seem to use.

Can't you connect your monitor using some other type of connection as neither s-video or composite allows such high resolutions. (the cabling supports upto 1024x768 I think)

Apologies for hi-jacking this thread, it seemed like the latest place to ask for help with Component out issues on my card.


My configuation:

Gigabyte GV-N62128DS board (AGP)
8178 drivers on Mandriva 2006
TV is Mitsubishi WS-65807

The TV only takes 1080i on component input. It works fine with a Comcast HD cable box.

I've tried a bunch of modelines I found here, at NVnews, and on the web. All of the ones that don't have errors exhibit the same behavior. If I switch the input of the TV to the PC, I can see a nice 1080i login screen for about 3 seconds. Then the TV determines the signal is no good and switches away from it. Component 480i using the same signal path is fine.

Here is the x.org config file The modlines marked almost exhibit this behavior:

here is a grep of the xorg log file

I'm beginning to think the card or the driver can't output proper 1080i.

Anyone have any ideas?
