The Vizio E320VP has an absolutely abysmal black level of 0.45 cd/m2. We typically don't expect entry-level LCD screens to produce the deepest blacks on the market, but this performance is just plain bad. For reference, a decent score would fall somewhere around 0.10 cd/m2, with anything falling above 0.20 cd/m2 appearing brighter than it should be. The Vizio E320VP's deepest black level is over twice as bright as that threshold. More on how we test black level.
Producing a bright screen is something that the E320VP doesn't struggle with, giving us a reading of 308.05 cd/m2, which is more than bright enough to provide a decent viewing experience in a well-lit room. Really, any brightness above 200 cd/m2 is adequate for this type of viewing environment, so the E320VP does fairly well in this regard. More on how we test peak brightness.
Due in part to its poor black level, the Vizio E320VP has a very poor contrast ratio of 684:1, as you can see by the provided chart. LCD screens sometimes struggle with this, especially when they fail to produce a decently low black level. Still, the E320VP struggles greatly in this area, and you may notice your picture performance suffer for it. More on how we test contrast.
Like many other LCD screens, the E320VP had no trouble at all maintaining consistent black levels regardless of how much or how little area of the screen was occupied by black area. More on how we test tunnel contrast.
Similarly, The E320VP had no issues in maintaining a consistent white level, regardless of how much area it occupies on the screen. We find that LCD screens typically excel in this area, and the Vizio didn't break this trend. More on how we test white falloff.
The E320VP has a fairly uniform screen, only showing a couple flares on a dark screen from its edgelighting, and an odd-looking grid pattern in the center of the screen. Other than that, you shouldn't notice many uniformity problems. More on how we test white falloff.
When we test greyscale gamma, we look at two aspects of our charts before scoring a TV's performance: the smoothness and slope of the line. The smoothness of the line tells us whether or not there were certain values of signal intensity that the TV simply couldn't produce, or if they were produced incorrectly. Ideally, the slope of the line should lie somewhere between 2.1 and 2.2, but depending on a TV's performance, this may vary. If it does, that means it doesn't quite produce the ideal values along the greyscale, which can result in lost detail, especially in shadows.
The E320VP didn't do too badly here: as you can see below, the line was very smooth with only a slight imperfection near the darkest end of the greyscale. The slope of the line below sits at 2.59, while not ideal, isn't terrible either. In all fairness to the E320VP, you are not likely to notice much detail loss in shadows due to the greyscale gamma performance. More on how we test greyscale gamma.
