We are keeping all TVs that we review for a few months after our reviews, so we were able to do a side by side comparison of the Vizio E60-C3, the M60-C3 and the P602ui-B3 (in that order in the picture).
Overall, the E isn't as good as the M or P. It is only 1080p and it has worse screen uniformity. It also doesn't have motion interpolation. However, the E actually has less motion blur than the M and P, which is a bit of a surprise.
The M and the P are very similar. They have the same motion blur and overall picture quality. The only differences are the stand, the design (the M feels higher-end), the 1080p upscaling (better on the M), the maximum luminosity (the P can get 25% brighter) and the local dimming (better on the P). The differences are minimal, so unless you specifically care about one of those elements, get the cheaper of the two.
As a side note, if you want to know something that isn't covered in our review (or is not covered as well as you would like), let us know and we will test it out.
HDMI 5 behaves differently than the rest of the HDMI inputs. It has lower input lag:
|HDMI 1-4||HDMI 5|
|Game Low Latency Off||103.6||84|
|Game Low Latency On||45.2||18.5|
Also, the upscaling behaves differently:
As with the P, the 'Clear Action' feature doesn't work. It only slightly reduces the backlight, without making any visible change to the motion blur. The feature works well on the E.
Vizio split the 'Smooth Motion Effect' feature into sliders: 'Reduce Judder' and 'Reduce Motion Blur'. Both settings interpolate motion and create the soap opera effect (even 'Reduce Judder').
Note that the long lighter motion blur trail problem is the same no matter the settings you choose for those options.
'Reduce Judder' affects 24Hz and 30Hz inputs. Here are pictures of all different values, when fed 30 fps.
'Reduce Motion Blur' affects a 60Hz input. Here are pictures of all the different values, when fed 60 fps.
Reviewed version: 1.0.6
Very often in our testing, even if 'Reduce Motion Blur' and 'Reduce Judder' were set to 0, the picture became interpolated. We had to reset it by setting 'Reduce Motion Blur' to 1 and then 0 again. Hopefully Vizio fixes this issue in a future firmware update, because it was frustrating.
Update: As a workaround for the soap opera effect issue turning on by itself, turn on 'Game Low Latency'. The downside of this approach is it will also disable 'Film Mode'.
Update: Firmware version 1.2.23-UHD appears to have fixed the interpolation issue.
Also, we are not sure if it is intended or not, but another slight issue is that we had to increase 'Sharpness' in our 720p and 480p upscaling test to 25 (from 0). With the P Series, we could leave it at 0 for these tests, but it was blurrier on the M if we didn't increase it on those resolutions.
The local dimming on the M behaves slightly differently under the 'Calibrated' picture mode than it does in 'Calibrated Dark'. It is more aggressive under 'Calibrated Dark', but the difference is very subtle:
The local dimming looks a lot more like on the E than the P. Like the E, it dimmed our white dot and cross in our tests, probably to reduce the appearance of blooming. The P keep the original brightness of the white elements. Therefore, if you care about the local dimming feature, the P is better, because it doesn't mess with the picture as much.
