Re: 1080i Resolution unused by nvidia-auto-select on 60-inch HDTV, [ Sony KDS-R60XBR1 ]
You ask why it can put analog 1080i on S-video and not on DVI. But it can.
DVI (in its DVI-I form) can output analog signals and with the correct modeline an NVIDIA card can output 1080i on that.
Of course it will be RGB and not Component, but you will not be hindered by the tv-out encoder and all its timing limitations. I use this with my TV.
Trust me, you will not be able to see any quality differences between digital or analog video on a HDTV. Digital has some merit w.r.t. pixel-perfect display on digital screens, but for playing movies on a HDTV there really is no difference.
