Blacks & Whites

The Sony was the superior display in our tests on the blacks and whites; it had significantly deeper blacks and a wider contrast ratio between the darkest black and the brightest white. However, the Vizio was the brighter screen overall, which may be an important factor if you want to watch it in daylight; the brighter the screen, the more it will stand out.

Color Accuracy

Both displays scored highly here; we found that they both had consistent whites and smooth RGB response curves. This means that you'll see clean, consistent whites and smooth color graduations. Both displays had slightly inaccurate color gamuts, though, which means that the colors on the screen may come out looking slightly differently to how the filmmaker intended.

Motion

Although it was a close-fought thing, we found that the motion on the Vizio was slightly better looking; although both produced significantly smoother motion than many other displays, the Vizio did a better job of preserving the fine detail of the objects. Faces, for instance, looked better because you could see more detail of the expression.

Viewing Effects

The Sony was the clear winner here; the image on the screen held its contrast ratio better as we moved off-axis, so those on the edge of a group would get a better image with the Sony than with the Vizio

Connectivity

Both displays have similar numbers of input and output ports: 4 HDMI ports  and a good selection of analog video inputs for connecting older equipment. They have somewhat different arrangements of ports, though; The Vizio has most on the back, but the Sony has 3 HDMI ports on the side. This might be an advantage if you are the sort of person that is constantly swapping connections in and out, but most users will want to plug in their devices on the back and not disconnect them.

Other Comparisons

Both displays can also play back music, photos and video from a USB thumb drive or other USB device, so you can show off your holiday snaps easily. Neither can play back videos or music from the Internet, though as they have no onboard Internet connections.
