Vizio VO47L LCD HDTV Review
The VO47L manages something of a tightrope act; keeping the price down, while still producing decent quality.
|Moving Video on the VO47LF was rather disappointing; video was jerky, and there were some quirks in the image with certain colors that were problematic. Overall, motion on this display was not particularly appealing.|
The VO47LF lacks the 120 Mhz refresh rate of many of the other displays that we have looked at, and it shows; the video is noticeably jerkier and less smooth than other displays. It's certainly not unwatchable, but it lacks the smoothness of the more expensive models, and video with a lot of movement in particular can turn into a blurry mess. One of the standard sequences we use to test is a clip from the hand-held camera action movie Cloverfield, and this was particularly difficult to watch; small details on the action sequences were just not visible.
There were a few issues with things appearing on the display that were not in the original video signal. One of our tests uses a moving color chart, and one of the greens in this chart seemed to move ahead of the rest of the chart. We weren't able to tweak the display to get rid of this issue. And, as mentioned above, videos with lots of movement lacked detail.
The VO47LF only did a lackluster job of detecting and processing a TV signal that included a telecine processing. Although it did detect the telecine on the Silicon Optix HQV test disc that we use and tried to process it, the result was a blocky, jerky mess. This test disc is designed to highlight issues, but our experience with a real video with 3:2 encoding wasn't much better; there was still some noticeable jerkiness and jittering to the image. The VO47LF was able to work with a 24 frames per second video image, though, and preserved as much of the filmic look of the source as the issues we mentioned above allowed.
