This TV has an excellent picture but poor, tinny, sound. The sound equalizer needs to be set high on both the low and upper frquencies to produce acceptible audio. A separate sound system would be a plus. Also the PIP function operation is poor and difficult to set up. It requires a separate sound setting when PIP is activated. The manual is not clear as to what component requirements are needed to activate PIP. The W-Link feature works very well to display digital pictures stored on a camera memory or storage device.Get more detail about Samsung LN37A550 37-Inch 1080p LCD HDTV.
