Re: 1080i Resolution unused by nvidia-auto-select on 60-inch HDTV, [ Sony KDS-R60XBR1
I also have the problem with 1080i outputing stretched, only showing the first 540 lines on the screen. I am on Ubuntu 7.04. I had the hardware previously outputing 1080i wonderfully on KnoppMyth using an older NVidia driver.
After hours of struggling I have it working, at least temporarily. The solution for me was to use nvidia-settings to set the resolution, and not the Ubuntu preferences. I tried this because the Ubuntu preferences always lists 50Hz for the refresh, and xrandr was saying the same.
I hope this information helps someone else out there. Tomorrow I will figure out how to make the settings stick.
