E600i-B3 vs M602i-B3 (Vizio E vs M series)

Both have full-array backlight as well as the ability to dim select portions of it, thanks to the local dimming technology. That said, the M602i-B3 has the advantage of having 32 active LED zones vs 16 of them on the E600i-B3, meaning the former can provide deep black levels under more complex scenarios involving multiple instances of both dark and bright elements being present within the same frame. The same is valid for the E600i-B3, albeit to a lesser degree. The smaller number of active LED zones and the absence of the Active Pixel Tuning technology, which the M602i-B3 is equipped with, lead to the contrast being lower on the E600i-B3, in addition to being more prone to blooming artifacts that may emerge as a result of dimming the LEDs. The maximum brightness on the E600i-B3 is 210 nits, while the M602i-B3 can reach 240 nits, which makes the latter slightly more suitable for brighter environments. The E600i-B3 has slight advantage over the M602i-B3 in terms of pixel response time: 4ms vs 6ms, respectively.

E650i-B2 vs M652i-B2 (Vizio E vs M series)

Although they both have Full-Array LED backlight and employ local dimming technology, the E650i-B2 has only 6 active LED (dimming) zones vs 32 on the  M652i-B2. The effectiveness of the local dimming technology largely depends on the number of these zones, and the more of them there are, the higher the precision of its operation is. With 32 active LED zones, the M652i-B2 is able to come closer to achieving the goal of providing deep black levels in different areas of the picture, even with bright objects being present within the same frame. The M652i-B2 uses the Active Pixel Tuning for brightness adjustments on a pixel-level in order to further increase contrast. Considering this technology is omitted from the E650i-B2 and the active LED zones are only 6, the contrast is lower on the E650i-B2. The maximum brightness the E650i-B2 is capable of is 340 nits, while the M652i-B2 can reach 400 nits, which makes the latter more suitable for brighter environments. Vizio specifies the number of colors the M652i-B2 can produce to be 1.07 Billion, which indicates that probably a 10-bit panel is being used (although 8-bit + FRC can produce the same amount of colors). In case of the E650i-B2, the available colors are 16.7 Million, so the panel is likely 8-bit (or 6-bit + FRC).

E700i-B3 vs M702i-B3 (Vizio E vs M series)

Although both the E700i-B3 and the M702i-B3 utilize Full Array LED backlight, there is a difference in the number of the dimming (or "active LED", as Vizio calls them) zones. The E700i-B3 has 18 Active LED zones while the M702i-B3 has 36. On top of that, the latter employs the Active Pixel Tuning technology, which provides a software adjustment of each pixel brightness in correlation with the displayed content so that the contrast can be further enhanced and the blooming artifacts, which may appear as a result of dimming the LEDs, can be minimized. The absence of the Active Pixel Tuning technology from the E700i-B3 and the reduced number of dimming zones mean that it's slightly more susceptible to blooming artifacts in addition to having lower contrast ratio. The maximum panel brightness is 210 nits in case of the E700i-B3, while the M702i-B3 can reach 240 nits, which makes it more suitable for bright environments.

UN65H8000 vs UN65H7150; UN55H8000 vs UN55H7150; UN48H8000 vs UN46H7150 (Samsung H8000 vs H7150)

Although both the H8000 and the H7150 have the same resolution of 1920x1080, the fact that the H8000 has a curved screen, while the H7150 relies on the more traditional flat panel makes them easily distinguishable. In order to create truly immersive experience, Samsung includes the Auto Depth Enhancer technology with their curved screens, and the H8000 is no exception. This feature works by automatically determining whether an object in located in the background, midground, or foreground, and accordingly adjusting the contrast in these areas as to create greater sense of depth. The size of the curved screen also plays an important role: for example, with the 65-Inch model (the biggest in the H8000 range), the so-called panoramic effect would be more pronounced in comparison to the 48-Inch model. On the other hand, the H7150 series goes up to the 75-Inch and its sheer size makes it impressive. In case of comparing a curved and a flat screen of the same size, the image on the former, due to the increased field of view, might appear to be slightly bigger than the one on the latter, but that depends on how far you are from the TV set.

TC-L55WT60 vs TC-L55DT60 vs TC-L55ET60 (Panasonic WT60 vs DT60 vs ET60)

The flagship WT60 series uses panel with 240Hz native refresh rate, while the the DT60 and the ET60 have 120Hz panels, thus they are not quite as good as their higher-end counterpart in terms of motion performance. That said, all three of them employ backlight scanning in order to be able to show fast-moving images without any blur. However, there is a difference in how this technique is implemented: in case of the WT60, 16 blocks are being scanned, while the step-down models scan only six blocks, so the DT60 and the ET60 are slightly less efficient in minimizing the flicker that the backlight scanning may cause, especially if it's done in less steps.

• The Hexa-processing engine can only be found in the WT60 and the DT60, which means the colors on the ET60 are not as vivid as on the higher-end devices, due to the lack of the picture enhancement suite. That said, all of them utilize IPS type of panels, thus the difference in the overall picture quality between the three models is minimal.
• The ET60 omits the two professional picture modes that can be found on its higher-end counterparts. The ISF (Imaging Science Foundation) modes are also missing from the lower-end device.
