I have purchased a new monitor and was told that the Spyder devices 
work great for calibrating both computer monitors and HDTV's.  Do they 
make on that would be able to do both types of devices or am I forced 
to purchse one for each purpose?  I have used a DVD program to 
calibrate my HDTV but it would be nice to purchase a device that would 
do both the TV and my monitor.
