On a recent trip to a dealer's store in Oregon, I experimented with the Oppo 203, one of the few UHD Blu-ray Players which allows individual selection of all parameters. I was able to individually select 4K 24Hz or 60Hz, 4:4:4, 4:2:2 or 4:2:0, 10-bit or 12-bit color and HOR or SOR. Wanting the best picture I chose 4K/60/4:4:4/l 2-bit/HOR. I pushed "PLAY" and got a picture. But, wait a minute that's not possible - I shouldn't get a picture because the settings far exceed the 18Gbs maximum data rate for the player, TV and the cable. If the settings exceed the systems specifications why did the TV display a picture? The reason is that the player automatically changed one of my settings, most probably the color depth from 10-bit to 8-bit. That brought the data rate back to l 8Gbps and, at 8-bit, HDR was compromised .. Therefore, if you want HOR don't set the player to 4K/60/4:4:4. Understanding the parameters, the possible combinations and how they impact the viewing experience are the keys to getting a display with the parameters you selected and ensuring your customers are getting the maximum return on their investment.
Here's a list of the parameters for setting up 4K a Btu-ray Player:
Frame Rate: 24Hz or 60Hz
Color Depth: 8, l 0, 12-bit
Color Sampling: 4:4:4, 4:2:2, 4:2:0 Dynamic Range: HOR or SDR
The game-changing feature for the newest 4K displays is HOR. However, for HOR to have its maximum impact the UHO Blu-ray Player's output must have its output setup for Deep Color, i.e., a color depth of l O or 12-bit. One way to ensure that Deep Color can be output is to set the Frame Rate to 24Hz (the native Frame Rate of almost all UHD Blu-ray discs). Then you can select 4:4:4, 12-bit, HOR and still be well within the operational envelope of the player and display. Another solution is to select 60Hz, 4:2:2, 12-bit, HOR. This solution requires l 8Gbps performance for all the components in the system including the HDMI cable.
