I have performed several experiments feeding HDTVs with a DVI to HDMI conversion cable.
With a Matrox Parhelia PCI AGP card and a DVI to HDMI conversion cable to the 23" Sony 720P HDTV (used as secondary) and 2 independent monitors setup the video card shows "1920 x 1080 31 fps interlaced" as the resolution and it does work very well. There is some overscan which means all the icons and applications have to be re-adjusted slighty to fit the full screen. Media player will play on both monitors at the same time (Primary monitor is a conventional 19" set to 1024 x 768) and the HDTV has to change the mode from "normal" to "full" for full screen viewing.
On a second computer with a Matrox Parhelia APVe card with dual monitor setup and a DVI to HDMI conversion cable from the primary feed to the HDTV the resolution selections were about 4 total, each saying "1920 x 1080 16 bit 30fps interlaced" to "1920 x 1080 32 bit 60 fps interlaced" so I used the 60 fps and it worked just fine. The icons get pretty small but with a big 32" monitor or HDTV they should be ok.
I have answered all of my previous stupid questions about doing this in previous threads. I have not tried this with 1080P HDTvs and wonder what resolutions will pop up on the video cards using the DVI to HDMI conversion method. Also don't know how accurate the 1080P HDTVs are to good CRT monitors.
