UN65HU9000 vs UN65HU8550; UN55HU9000 vs UN55HU8550 (Samsung HU9000 vs HU8550)

The HU9000 curved screen and, respectively, the HU8550 flat one constitute the biggest difference between the two Ultra High Definition series. In order to complement the curvature, the HU9000 is equipped with the Auto Depth Enhancer picture technology, aimed at delivering a greater sense of depth by the means of automatically detecting whether an object is situated in the foreground, midground or background of the picture, and applying the necessary contrast adjustments to these areas. That said, how immersive your experience with the HU9000 will be, depends on the size of your TV and how far you're seated from it. According to Samsung, their curved UHD TVs offer an optimal curvature of 4200R, which ensures the best picture quality from a normal viewing distance of 10 ft to 13 ft (for the different screen sizes), thus allowing you to benefit from the curved screen, and in particular: the wider field of view, without any significant drawbacks. The curvature leads to generally wider viewing angles, but any extreme off-axis seating positions are to be avoided because the near side view would be restricted. With the flat-screen HU8550 you don't have to worry about any hypothetical distortion if you find yourself outside of the optimum position; however, the viewing angles are quite limited by the VA-type of panel that is used.

Another significant distinction between the HU9000 and the HU8550 is the inclusion of the new PurColor technology in the former one, which allows the HU9000 to display more natural-looking colors, with more detailed shades, thanks to the sevenfold increase in the color adjustment points. While the PurColor is omitted from the HU8550, there are plenty of picture-quality related features that the two UHD series have in common: the UHD Dimming (which works by processing numerous blocks across the image and applying adjustments for contrast, color and detail to each of these blocks individually), and the Precision Black Local Dimming. In case of the latter, the LEDs (light emitting diodes) corresponding to the dark areas of the picture are dimmed, while the brighter elements are kept intact, so the result is more contrasted image and darker blacks. The Wide Color Enhancer Plus can also be found in both UHD series.

The HU9000 has a Quad Core Plus processor, while the HU8550 has the regular Quad Core. The difference being the higher clock speed of the former one, which translates to more fluid Smart Hub experience, with faster browsing and multitasking. The HU9000 has a built-in pop-up camera, which allows for the Smart Interaction to be accessible out-of-the-box. If you want to use the same functionality with the HU8550, e.g. controlling your set with various hand gestures, you'll need to get an external camera, since there's no built-in one. The Smart Remote Control with a built-in microphone is included with both series, so you can use voice commands with either of the two.

The HU9000 also has a higher clear motion rate index of 1440 compared to the HU8550's 1200 CMR. The discrepancy is attributed to the differences in either the image processor speed or the backlight scanning rate of the two sets. However, the panel native refresh rate is 120Hz in both cases, so they're just as suitable for fast motion programming.
