The Ultra HD Blu-ray player market has shown drastic signs of decline in comparison to the DVD players of old. In my own experience, I was able to walk into a store and leave with over twelve models, all representing very diverse manufacturers. Retailers have been forced to keep prices low on blu-ray players with the popularity of streaming services as well. But even when it comes to these discounted devices, we’ve experienced a decline in quality across the board. Granted, the quality of the media is fantastic. Ultimately, it just has to perform its duty by simply passing this data along to the TV screen. You must also get plenty of discounts on Black Friday and Cyber Monday sales.

Panasonic DMP-UB820 4K Blu Ray Player The DMP-UB820 has been praised for its HDRI Optimizer which was specifically made to correct the HDR troubles of displays that either can’t support HDR or do not display it in compliance with what is expected. The UB820 is the first player I’ve heard about that supports the new HDR10+ format. Future-proofing is a major consideration, and the Panasonic DP-UB820 4K BluRay Player includes support for future HDR formats. The DP-UB820 is a $499 Blu-ray player, but it’s the best one for users who stick to streaming.

The flagship UB820 resembles the much more expensive DMP-UB900 reviewed in Sound & Vision magazine. The Panasonic DP-UB820 is a BluRay player with the ability to playback 4k. The features are nearly identical to that of the UB900, but it lacks some key features like touch-sensitive controls and THX certification. The remote that is included with the UB900 has a more spacious layout and backlight, which I find preferable to the remote on the UB820.
Panasonic DP-UB820 and Sony UBP-X800 are both very good players in the market, but there is, unfortunately, a bit of disconnect when it comes to HDMI inputs. This is a welcome addition to the player that makes it easier for other sources to take advantage of its special HDR processing capabilities.

Panasonic DP-UB820 4K Blu-ray player I want to give attention to the HDR performance and processing. I’ve found that the arrival of HDR has been both a blessing and a curse. It gives me the best video I’ve seen in my home, but its implementation is abysmal at best when it comes to pre-recorded media playback or display. Onboard processing does a great job with HDR on the UB820.
To understand 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.
Now, in reviews or blogs that may recommend this Before HDR, media was mastered for screen brightness of 30 foot-lamberts (approximately 100 nits). Today’s TVs are reasonably capable at this level, but with the newer standard for mastering and playback HDR10 clocking in at 10,000 nit possibilities it is hard to go back. We have yet to see HDR content graded at 4000 nits, but we’ve seen some on mastering displays able of up to 4,000.
No matter the cost or type of display, it’s still not enough to convincingly show a 4,000 nit video. Tone mapping is how content mastered at 40 percent of its original brightness will look like on a 25 percent display. 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. I am very impressed with how bright the Panasonic DP-UB820B 4K UHD Blu-ray player is, which has an increased brightness level compared to most other displays. Tone mapping can be used in order to achieve a more realistic picture and better accuracy for colors.
When the brightness is set to the desired level, any other detail in that program becomes compressed. When tone mapping is initially applied, these graphs may seem like a crossover filter in an audio system. The issue with this technique is that there’s no universal standard for it–every TV manufacturer maps the input differently.
