Motion Performance*(12.00)*


The Sony KDL-46BX420 actually didn't do too badly with displaying a smooth motion performance, maintaining a nice level of detail in motion and no issues that we normally see in refresh rate with entry-level TVs. There was an appreciable amount of artifacting in every single one of our test patterns, and no feature to really deal with this. Still, the overall performance was good, so theSony KDL-46BX420 shouldn't disappoint in this area. ( More on how we test Motion.)

3:2 Pulldown & 24fps*(7.75)*


The Sony KDL-46BX420 had a few minor issues with 3:2 pulldown and 24fps content, despite its additional video processing feature to specifically deal with this. While it handled film content in an acceptable manner, it didn't seem to handle high-frequency patterns all that well, showing a little bit of strobing that was mostly fixed by its Cinemotion video processing feature when turned on. (More on how we test 3:2 Pulldown and 24fps.)

Resolution Scaling*(8.68)*


The Sony KDL-46BX420 has a native resolution of 1080p, but can display all standard NTSC resolutions, but performance changes with content from each resolution to another. Below is a summary of performance issues in the most common resolutions. (More on how we test Resolution Scaling.)

480p

The Sony KDL-46BX420 lost 2% of its screen vertically and 3% horizontally to overscan, and showed absolutely no issues in our other resolution tests. 

720p

The set lost 2% of its screen area vertically and horizontally to overscan, and displayed significant troubles with high frequency patterns.

1080i

The KDL-46BX420 lost no screen area to overscan and performed remarkably well in our other resolution tests.
