The plus of buying a monitor is that they are not meant for multi-purpose so all the money goes into the display. Only one HDMI input means you'd have to decide if you want a Blu-ray player or hook up the satellite to handle HD. The sound is an afterthought on most TVs but on a monitor, it's usually not even offered. If it is, the standard is two speaker 10 watts which leaves you missing that important middle channel that is voice only, not to mention practically no bass and the sound effects from movies of the last 30 plus years. I haven't checked to see if the SONY has an adjustment to change the volume on the center channel which is important. I have my Yamaha set above the factory and testing level so I rarely get whispering voices. But some films are guilty of a dynamic range that's really messed up, like "Slumdog Millionaire" where the center channel voices are often close to inaudible but if one turns them up, the special effects like a train going bar are ear splitting. I can change the surround settings quickly and that sometimes helps but easier access to the volume of the center channel would help. If I select "concert hall," solo voices or instruments are lost in the orchestra. My Yamaha does have a "General" movie setting which is aimed at old movies and enhances the center channel. This is because the old stereophonic movies mixed in the actor's voices into multiple channels across the CinemaScope screen so it would sound like it was coming from that part of the screen which is no longer done. If you notice on old CinemaScope, it was a habit of the director to have his actors on the far side of the left and right hand side of the screen to show off the wide screen, like the ping-pong effect in the first stereo recordings.
Read that review of the SONY -- it does have automatic level tuning with a microphone to place in the sitting area. It has three HDMI connectors which means you can attach more than one HD combonent to the monitor. But the sound quality is for most movies and not meant for listening to music.
