The Q6FN and NU8000 differ mainly in terms of the DCI-P3 color volume (which leads to a certain variation in the color saturation with HDR content, especially during bright scenes), their picture engine (which has an effect on the upscaling and SDR to HDR upconvertion, however slight), and design (the table top stand and the color of top and left/right side bezels).
The NU8000 and MU8000 differ in their DCI-P3 color volume (although neither of them has quantum dots like the Q6FN does), the software dimming technology, the Smart TV system, the inclusion of One Connect Mini box (or lack thereof), and the table top stand.
1. Quantum Dots (only Q6FN)
The Q6FN utilizes quantum dots for the purpose of optimizing the spectrum of the backlight in order to closely match the color filters. This in turn leads to the primary colors on the Q6FN being spectrally pure, and allows the Q6FN to reach full coverage of the DCI-P3 color space (although this may vary slightly depending on the chromaticity diagram it is measured against). The NU8000 and MU8000, on the other hand, don’t use quantum dots so the DCI-P3 coverage is lower.
NU8000 vs MU8000
Neveltheless, the fact that the NU8000 and MU8000 still support wide color gamut indicates they are able to achieve somewhat narrow peaks in the red, green and blue regions. The NU8000 has a slight advantage over the MU8000 in that regard, meaning it covers a larger portion of the DCI-P3 color gamut than the MU8000, albeit the omission of quantum dots means that the peak wavelength of the emitted light cannot be tuned with the same level of precision as the Q6FN can.
2. 100% Color Volume (only Q6FN)
The Q6FN is able to cover the DCI-P3 color gamut entirely at different luminosity levels, hence the 100% Color Volume. The Q6FN’s advantage over the NU8000 and MU8000 is most pronounced at higher luminosity levels where more saturated colors can be displayed than either the NU8000, or the MU8000 are capable of. In other words, the Q6FN is able to faithfully show colors in HDR content that is graded in DCI-P3, especially in highlights (at least when the HDR10 content has been mastered to 1,000cd/m2, whereas the NU8000 and MU8000 cannot reach the same level of saturation as the Q6FN when showing brighter colors. The difference between the Q6FN, on the one hand, and NU8000 and MU8000, on the other, in terms of DCI-P3 gamut coverage is less drastic at lower luminosity levels, meaning the color saturation in shadows and mid-tones is less varied between the three TVs.
NU8000 vs MU8000
The color volume is not the same on the NU8000 and MU8000 due their different peak brightness output, as well as the variation in the DCI-P3 gamut coverage at different luminosity levels. Specifically, due to the higher peak brightness on the NU8000 vs MU8000, the color volume is also higher (but still lower than the Q6FN). As already mentioned, this can be observed mainly in bright scenes.
3. Supreme UHD Dimming vs UHD Dimming
All three TVs are edge-lit, meaning the LEDs are placed alongside the bottom of the panel. The light is distributed across the panel thanks to a light guide plate. This backlight structure limits the number of local dimming zones, and their impact on the picture quality. In order to make up for the limited effect of the hardware-based dimming of the LEDs, the Q6FN and NU8000 utilize a picture processing technique called Supreme UHD Dimming, whereas the MU8000 is equipped with the UHD Dimming. Therefore, the Q6FN and NU8000 have more detailed brightness processing and adjustment capability than the MU8000. That being said, there is a difference in the processor used on the Q6FN vs NU8000. The former has the Q Engine whereas the NU8000 is equipped with the UHD Engine which is also used by the MU8000. The Q6FN’s Q Engine intends not only to improve the clarity and color of upscaled content, but also to extend its dynamic range.
4. One Connect Mini (only MU8000)
While the Q6FN and NU8000 have all their inputs on the back of the TV, the MU8000 has only one USB port, an Ethernet port, and a RS232C (Ex-Link) on the back. The remaing connections: 4 HDMI inputs, 2 USB ports, a Digital Optical Audio Out and RF In are located on the One Connect Mini box. Another difference is that the Q6FN and NU8000 have a total of 2 USB ports each whereas the MU8000 has a total of 3 USB ports (albeit at two different locations).
The Q6FN and MU8000 have nearly identical, A-shaped table top stand that consists of two separate legs that have to be attached near the left/right side of the TV. The NU8000, on the other hand, has a table top stand that consists of a central rear support column and a T-shaped front part. The NU8000 and MU8000 use a dual color scheme with the lower bezel and the stand being silver whereas the top and the left/right bezels are black. In case of the Q6FN, both the stand and the frame around the display are silver.
6. Smart TV platform
Being 2018 models, the Q6FN and NU8000 have the latest edition of the Samsung Smart TV system. Amongst the new features this year are the Universal Guide which combines content from different sources and apps into a single menu; Ambient Mode which allows your TV to blend into its surrounding while still showing some useful information such as the weather and news headlines. Furthermore, the Ambient Mode can be used for displaying photos or playing music (from a mobile device or cloud service). In order to use some of the Ambient Mode features, however, you’ll need the SmartThings app (for Android or iOS devices). The MU8000, on the other hand, lacks the Ambient Mode and the Universal Guide but still includes Smart remote that is similar to the Samsung OneRemote of the Q6FN and NU8000. Although the MU8000 has voice control capability, the Q6FN and NU8000 have an advantage in that regard thanks to Bixby – which is an intelligent voice assistant.
