HDTV as pc monitor-no digital signal

\015 Hello:My 24'' monitor failed and I purchased a Samsung 23'' HDTV to use as pc monitor.Although I had digital display on previous monitor, I cannot now get digital signal, onlyanalog. Also, every reboot changes color to16 bit rather than 32.I'm using xp and a DVI cable from pc to monitor.I'm using same video card (Radeon 9200) that I used with previous monitor but can't get same results.Any help would be greatly appreciated as I have spent hours tormenting with this.Thanks\015

Answers :

Try different Resolutions/DPI and Refressh rates the other possibility is settings on the monitor check the manual of the monitor for use with the pc as in resolution etc.
\015\012Newer monitors oftem change there own settings to best suit themselves or act differently if forced to use different settings.
\015\012The returning to 16bit seems odd though only other suggestion is trying updated video card drivers from the vendors site.
