Value Comparison Summary The SV471XVT is an upgrade to the SV470XVT, but the older model is not going away: it is generally available for about $1300 and sometimes pops up for less than $1000. That's a significant saving over the new model, but the SV471XVT does offer a number of improvements over the older model (Brighter screen, better motion and photo/vieo playback) that might justify the extra.
Blacks & Whites The two Vizios are mostly equal in performance terms, but Vizio seems to have jacked up the brightness of the backlight on the newer model, which means that the screen can be significantly brighter. The black level is unchanged, though.
Color Accuracy Both models also had very similar performance in our tests that looked at color performance; they both produced whites that remained constant and had a clean, smooth response for the RGB curves. What this means is that they both produce good looking, accurate color, and that there is very little difference between the two models.
Motion Motion is one area where there is a definite difference between the two models; we saw much smoother motion from the SV471XVT, which has faster motion processing. But the SV470 wasn't bad by any stretch; it produced very smooth motion .
Viewing Effects The viewing angle of the display is one are where Vizio seems to have taken a backward step; the SV471XVT had a smaller viewing angle than the SV470XVT, which was pretty poor to begin with. We measure the angle at which the contrast ratio between the blacks and whites drops by 50%, and this angle on the SV471XVT was a very poor 25 degrees, while the SV470XVT managed 38 degrees.
Connectivity There have been no major changes for the inputs and outputs between the two Vizio displays, with the exception of the addition of a USB port. Both displays have enough inputs to allow you to connect a wide range and number of devices. The only other change is the location of these ports: on the SV470XVT they were located on the bottom of the back, which could be slightly awkward to reach. In the SV471XVt, they are on the back of the display, and are much easier to reach.
