DNR is also designed for analog TV signals and is sometimes found on DVD players and satellite/cable boxes. It filters out video noise. Sometimes this feature is manually adjustable to your liking.
Make a note of what you plan to connect to the TV, and then plan ahead for things you don’t yet own. You’ll need at
least one set of component inputs for a DVD player, an input for an HDTV tuner (either component, DVI or HDMI), plus some other S-video and composite inputs for VCRs, video game machines, camcorders and maybe a DVR or DVD recorder. Front inputs are also helpful
for camcorders and game consoles.
Also, make sure the TV has the correct audio inputs.
