Best Panasonic DP-UB820 4K Blu-ray Player Black Friday & Cyber Monday Deals 2021
Today’s Ultra HD Blu-ray player market is drastically smaller compared to the one for the spinning-disc machines of old. In my own start reviewing DVD players, I possibly could literally enter an electronics store, go out with over twelve players, and that could only represent a sampling of the available models. But with the massive rise in the popularity of streaming, we’ve seen the player market continue steadily to lose fat. On the plus side, the caliber of the UHD Blu-ray players we’ve seen has been uniformly good. Granted the caliber of the disc media is fantastic, so ultimately the player just must pass that data along to the display with only a small amount manipulation as possible.

Because of this review we’re likely to look at a fresh UHD Blu-ray player from Panasonic that truly does quite somewhat of manipulation, but also for justification. Panasonic’s DMP-UB820 may be the first player to provide advanced onboard tone mapping for High Dynamic Range (HDR) and Standard Dynamic Range (SDR) playback. The HDR Optimizer feature within the DMP-UB820 was made to correct the HDR troubles of displays that either don’t support HDR or don’t execute a congrats with it. The UB820 can be the first player I’m alert to that supports the brand new HDR10+ format. While no discs exist yet in this format, having that support helps future-proof the player. Hybrid Log Gamma (HLG) HDR can be included and Dolby Vision support will be added in a firmware update slated for Fall 2018. At $499, the UB820 is a mid-to-upper-price offering, but continue reading to understand why it’s the very best player yet for corralling the wild, wild west of HDR.
The UB820 closely resembles the Panasonic DMP-UB900 reviewed in the February/March 2017 Sound & Vision, a new player that earned top marks because of its performance and remains among our top picks. I’ve owned the UB900 myself and found its video playback functions first rate, though its ergonomics didn’t match me together with my reference Oppo Digital UDP-205 player. The UB820 is practically identical to the UB900 from a day to day procedure standpoint: its menu structure and home screen will be the same, and both players have the same sleek look, although UB820 lacks touch- sensitive controls, THX recognition and other minor details which make it feel slightly less high-end. I really do prefer the UB900’s handy remote control to the UB820’s, which is smaller and lacks the backlit keys and spacious layout of the remote that is included with the older Panasonic player.
The trunk panel of both players are practically identical with dual HDMI outputs (one audio-only), a 7.1-channel analog music output, USB support and a LAN connection. All standard fare because of this market, but I was bummed to notice having less an HDMI input. That’s an attribute that the now discontinued Oppo Digital players offered, and is a welcome addition to the player in order that other sources could take good thing about its unique HDR processing. (WHEN I dive in deeper on that topic, you’ll realize why.)
HDR, SDR, Gamma, And Tone Mapping
I’m not likely to talk a lot more about the UB820 itself since I came across its performance to be practically identical atlanta divorce attorneys way to the previously reviewed UB900. What I want to give attention to is what sets this player apart: HDR performance and processing. The arrival of HDR has been both a blessing and curse. It gives the very best video I’ve ever seen in the home, but I’ve found its implementation to be abysmal at best, with standards lacking for pre-recorded media, playback, and display. HDR in addition has produced just one more format war to confuse consumers. Fortunately, the UB820’s onboard processing does a formidable job of beating back most of the HDR demons.
To comprehend the UB820’s unique advantages, we’ll first have to discuss the specifics of HDR. This relatively new format was made to leverage the bigger light output capacity for today’s displays-a capability that was wasted on almost all of the programs we’ve been watching for a long time. Before HDR, consumer media was mastered for display at 30 foot-lamberts (approximately 100 nits) brightness, which is on the dim side for some flat-panel TVs. HDR10, the standard HDR format and one that’s mandated for inclusion on all UHD Blu-ray discs, supports brightness levels up to 10,000 nits! Granted, we’ve not yet seen programs graded at that brightness level, but we’ve seen some which were graded on mastering displays with the capacity of up to 4,000 nits, which is far beyond the ability of any consumer TV available to buy.
Just how do you display content mastered at 4,000 nits on a display with the capacity of only 25 percent of this brightness or less? Tone mapping. SDR content is mastered using what we commonly call gamma. This technique measures the peak white output of your display and balances the grayscale intensity compared to that level. HDR, on the other hand, uses absolute values that are designed to map right to the display without wiggle room because of its overall light output. To properly show quite happy with an increased brightness level compared to the display is with the capacity of hitting, tone mapping can be used.
The standard way to describe this technique is that the display shows this content as intended for up to its brightness capability allows. From then on point, any remaining detail that exists in this program gets “rolled off.” This compresses information at the high end of the brightness range in order that you are not simply clipping the signal. In the event that you were to graph the response, it could almost appear to be a crossover filter within an music system. The problem, however, is that there is absolutely no standard of any sort for tone mapping, so every TV
