I don't think a DVD player is necessary if you have a computer onboard. Also, there is not much distinction between TV's and monitors anymore. Purchase
with a built in tuner or purchase
an external tuner. Try to find a monitor
with S-Video, VGA, DVI and maybe even HDMI. Owning such a monitor will give you greater flexibility in what you can watch on it. If you have a Bluray player/burner in your computer you could watch movies in high definition, provided you bought a monitor with enough resolution. There are graphics cards with HDMI out ports
for watching movies in high definition.
