In the Sony Bravia KDL-46V2500 operations manual, downloadable from: http://esupport.sony.com/perl/model-documents.pl?mdl=KDL46V2500 There is a PC input signal reference chart, the highest resolution listed is 1400x1050. In my case I was using a Sony Bravia KDL-46X2000 (native 1920 x 1080), it's max listed VGA resolution in the manual was 1360x760 and that was the best I could get out of it over VGA. >> but has no problems with HDMI (1080i or 1080p, 50 or 60Hz).

Do such things exist? If not, are there > any options beside DVI-over-cat5? The store where I bought a 5m (~16ft) HDMI to DVI cable was also selling 15m (~50 ft) cable lengths. Sorry, I have no first hand experiance with HDMI/DVI cables of that length. Cheers, Doug
