Inquiry: Solution for 4K Blu-ray Image, Differences Between Lossy and Lossless Compression, AI Auto-Calibration.
In this episode of "You Asked": What is the best 4K Blu-ray picture? What is better: lossless audio or Atmos? Additionally, is it possible to have a TV that self-adjusts using artificial intelligence?
The current discussion revolves around various questions regarding display and audio technology. A user, who enjoys their Sony A95L and Panasonic DP-UB820 Blu-ray player, feels disappointed with the image quality of 4K Blu-ray movies, comparing their experience to cable and streaming signals that seem to offer better visual quality. The conversation centers on potential settings that could enhance the viewing experience.
It is mentioned that despite 4K Blu-ray discs having a higher bit rate and color depth, which theoretically should improve image quality, personal preferences might play a role. On one hand, some users prefer the appearance of SDR image, which tends to be brighter and more uniform, compared to HDR, which can appear darker in not perfectly dark environments. Additionally, it is noted that the issue might lie in the TV setup, as many models require specific adjustments to enable HDR on HDMI inputs.
In the realm of TV reviews, the review of the 65-inch TCL QM8 is anticipated. The critic’s focus is currently on other models, including some Panasonic displays that are returning to the market after a long absence. The recent addition of a Samsung QN90D television is also mentioned, which has increased the workload for reviews.
The comparison between lossless audio and Dolby Atmos on platforms like Amazon Music and Apple Music is also a topic of discussion. While lossless audio generally provides better quality, the Dolby Atmos format offers mixes that can vary significantly in quality. The Atmos mix can be exceptional or, in some cases, disappointing, depending on how it has been designed.
Finally, the possibility of using artificial intelligence (AI) to calibrate televisions is addressed. Although there are basic calibration apps, the use of AI could facilitate the customization of image settings according to user preferences. However, this would require collaboration between manufacturers and software developers, as well as the inclusion of measurement devices for a more precise calibration process. While it is an interesting possibility, effective implementation may take time to materialize.
