2.1 HDMI Standards: Everything You Need to Know

 

With the launch of HDMI 2.1, certain AV devices such as TVs, computers and gaming systems can now have even more seamless connectivity and immersive experiences. In this article, we’ll discuss the differences between HDMI 2.0 and 2.1, the exceptional features HDMI 2.1 offers and a new type of cable you should know about.

HDMI 2.0 vs. 2.1: What’s the difference?

The key differences between HDMI 2.0 and 2.1 are substantial upgrades in bandwidth, video resolutions and refresh rates. HDMI 2.1 now supports a maximum bandwidth of 48 Gbps, 4K resolution at 120Hz and 8K resolution at 60Hz. On the other hand, HDMI 2.0 only supports a maximum bandwidth of 18 Gbps, 4K resolution at 60Hz and 1080p resolution at 120Hz. HDMI 2.1 also offers support for devices with 10K resolution, which are most used for commercial AV and industrial applications.

HDMI 2.1 features

HDMI 2.1 introduces new and advanced capabilities that amplify the overall viewing experience. These include the following:

  1. Dynamic HDR – HDR enriches video images with deeper black and brighter white colors, which offers more natural and realistic pictures. Dynamic HDR delivers better picture quality, compared to SDR and static HDR, by applying metadata to each scene. Metadata is additional information found within content used to optimize tone-mapping.
  2. Enhanced Audio Return Channel (eARC) – eARC is simply an improved version of Audio Return Channel (ARC) that offers higher bandwidth and speed. With ARC, an HDMI cable can transfer visual and audio information between AV devices such as TVs and amplifiers. And with the arrival of eARC, people can now enjoy better audio quality and use advanced audio formats, such as Dolby Atmos, Dolby TrueHD and DTS-HD Master Audio. It’s important to note, if you are using HDMI extenders to deliver the signal over long distances (which can be up to 328 feet), only select extenders will be able to pass a signal with eARC.
  3. Variable Refresh Rate (VRR) – VRR is an exclusive feature of HDMI 2.1 that automatically matches the display’s refresh rate to the frame rate of the content – meaning less lag and screen tearing. This capability is especially helpful for gaming consoles that undergo rapid drops in frame rates due to sudden image and color changes.
  4. Quick Frame Transport (QFT) – QFT is also another exclusive feature of HDMI 2.1 that reduces the latency between the source device and the display. QFT ensures that every single reaction is relayed onto the display in real-time, which results in faster response times and less lag.

HDMI 2.1a: Source-Based Tone Mapping (SBTM)

SBTM enables the source to transmit a video signal optimized for a display’s HDR capabilities to further elevate the viewing experience. SBTM can be used by PCs and other devices to eliminate the manual user optimization for HDR. In short, SBTM is used to supplement HDR10, HDR10+ and Dolby Vision formats.

Additional tips to recruit and retain talent

In addition to these core strategies, you should consider the following tips for long-term success.

Regularly review and update policies: Review and update recruitment and retention policies to ensure your job offerings remain competitive. As an employer, you can accomplish this by staying informed about the latest hiring practices and tactics. Plus, soliciting feedback from employees on existing policies and incorporating their input can lead to policies that better resonate with your workforce.

Monitor employee satisfaction: Implement regular satisfaction surveys and other mechanisms for employees to provide feedback, such as suggestion boxes and open-door policies. These tools provide valuable insights into your strengths, weaknesses and areas of improvement as an employer. By executing these initiatives, you also create a culture of continuous improvement and a positive work culture and demonstrate a commitment to the well-being and satisfaction of your workforce.

Conclusion

The persistent challenges that arise with a lack of skilled candidates leave integrators actively seeking ways to attract and retain motivated employees. However, by understanding and applying creative recruitment and retention strategies, integrators can overcome these challenges, and ultimately construct a highly motivated workforce. And those who prioritize these tactics will be better equipped to navigate the complexities of building and sustaining long-term, loyal employees.
