Re: nvidia 100.14.19 1080i stretches screen
I've never been able to get a manual modeline to do 1080i with an nVidia driver.
I have been able to get the EDID 1080i mode to work (using DVI->HDMI to my Sony TV), but only with 8776 and earlier releases. It works quite well, actually. The only problem is that I don't think I can upgrade to the latest X release, and possibly the latest kernel releases while running a driver that's over a year old.
Of course, to get the EDID 1080i mode to work in 8776, I had to use the option to ignore the vertical refresh rate when doing mode validation.
