The Samsung F4500 is a great entry-level plasma with beautiful blacks and shadows. If you are sitting close to the television, though, its low resolution (720p) will bother you. Also, the panel reflects a lot of ambient light, so this television is more suitable for a basement or for those who watch television at night.
The F4500 performs really well in a dark environment where you can benefit from its deep blacks.
If you have a lot of windows, you won't be able to appreciate this TV during the day. It reflects too much light.
The reflections are a problem even during bright scenes.
If you are sitting closer than 8-10 feet, get the Samsung F5300 Plasma TV instead. Otherwise, this Samsung F4500 Plasma TV is a very good budget plasma TV, assuming you do not have a lot of lights in your room.
