Sony KDL-46NX720 LED LCD 3D HDTV Review$999.00
The KDL-46NX720 nets a low-average motion score here, as it struggled with maintaining picture quality in motion, and added in a slew of artifacts that were unable to be corrected with any of the video processing features loaded onto the set. Considering how expensive this TV set is, we'd expect a little better showing here, but the artifacting issues were too much to ignore. More on how we test motion performance.
3:2 Pulldown & 24fps
Keeping consistent with the problems mentioned in the motion performance section, the KDL-46NX720's native 3:2 pulldown processing feature does an average-at-best job at handling film content. In moving high-frequency patterns, the KDL-46NX720 showed worse strobing and artifacting with the feature on than when it was forced off. With the feature turned off, the KDL-46NX720 handled film content at an acceptable level of performance, but again, nothing very impressive. More on how we test 3:2 pulldown and 24fps.
Due to the fact that not all external content is the same resolution, we test how well each TV set handles the task of rescaling images of differing resolutions. Below is a summary of how the KDL-46NX720 handles each common NTSC resolution. More on how we test resolution scaling.
The KDL-46NX720 lost 3% of its image to vertical overscan, and 2% of its image area to horizontal overscan while displaying 480p content.
While displaying 720p content, the KDL-46NX720 lost 2% of its image area to horizontal and vertical overscan. In addition, it displayed some false coloration in high-frequency patterns.
Oddly enough, the KDL-46NX720 showed the same loss of 2% of its screen area horizontally and vertically to overscan, as well as showing significant interference in high-frequency patterns.
