Vizio VP422 Flat-panel TV/Monitor - Quality
(Page 4 of 4 )
As previously stated, display quality is not the highlight of the Visio VP422, price is. On that note, the quality of the television really is not so poor that you cannot use it. The deep black levels of the television combined with the impressive brightness and contrast ratio actually make for a fairly respectable combination. The TV's true shortcoming is in terms of color accuracy, especially in terms of green values and gray scale.
The default gray scale settings are actually pretty awful. In warm mode, the screen becomes remarkably red. It takes some fiddling to get the settings just right, but once you do, the picture is pretty usable. With a little bit of work, you can adjust the green value quite a bit to get it accurate; you will also have to work with red for a little while. Interestingly, blue actually provides a relatively accurate display right off the bat.
The depth and distinguishing capability of deep blacks on the VP422 beat out the quality of most of its competitors. The blacks really are quite impressive for the price tag. Of course, the VP422 does fall behind some of the more expensive sets, but that is to be expected.
As I mentioned, color accuracy just is not very good with the VP422. This seems to be an industry-wide problem with plasma televisions, but Vizio did not even hit that mark with this 42" screen. Even after adjusting the color values for optimal quality, skin tones (among other things) just do not come out right.
The video processing capability of the VP422 is pretty impressive, and does well with both SD and HD. It passed a quality test with Blu-ray and did very well with eliminating noise in low-light settings.
As expected from a typical plasma television, the Vizio VP422 did quite well with white field uniformity. Although this does not give the VP422 an edge over its plasma brethren, it does give it a mark over many LCD televisions.
The VP422 did not do quite as well as average on standard definition tests, though it did not do too poorly. It did well in all of the tests except in jagged edge reduction and noise reduction. Although performances in each of these areas were sub par, you just cannot expect everything to be great from one of the cheapest televisions on the market.
As mentioned in the features section, the VP422 does offer its capabilities for PC users as well. It does well enough in this area, and displays everything that it should, as it should. Of course, the one limiting factor is the relatively low resolution for such a large display screen.
