Hmmm... I can´t believe that Toshiba is lying about such a important feature. Again from the avforums:
"Via PC (without needing to use Powerstrip) Nvidia 6800gt (PCI-e) DVI to HDMI lead, I have 1920x1080 as an option. I tried this and initially there is overscan, but using exact scan option (on TV) it is very very nearly 1:1 mapped (no overscan). I say nearly because as I type this some letters are not perfectly crisp. This is at 60Hz, you can also choose 50Hz (I watched some 50hz avi's, which in the most part were ok, slight ripple at one stage.......I do not have time to check a pal dvd just yet), there is also a 24Hz interlaced refreshrate.
I have now tried the 24hz interlaced input (from DVI PC), and using exact scan, with 24fps source material looks very good, no interlacing issues, when I press pause."http://www.avforums.com/forums/showpost.php?p=4745465&postcount=180
