Read some of the 57 Newegg reviews.
Reviewers in general all seem to agree that it's a good HDTV, and gave it a 5 egg rating.
However, some of these same reviewers also said this for CONS:
- black level is subpar
- HDMI connection might be laggy
- colors looked washed out if you're not at the optimum angle (dead center?)
- text is hard to read in 1080p mode
Based on this, I would stay away from this TV if you plan to use it as a PC monitor. Great for TV though
