To split the HDMI audio signal to transmit HDMI ARC to HDMI Bluetooth, you can use an HDMI audio extractor. This device can extract the audio signal from the HDMI ARC connection and then transmit it to a Bluetooth transmitter, which can then send the audio to a Bluetooth-enabled device such as a speaker or headphones. Make sure to choose an HDMI audio extractor that supports ARC and has a built-in Bluetooth transmitter for seamless transmission of the audio signal. **

An HDMI to HDMI adapter is used to connect two HDMI cables together to extend the length of the cable. It is commonly used when the existing HDMI cable is not long enough to reach the desired device. This adapter allows for a seamless connection between two HDMI cables without any loss of signal quality. **

The better connection depends on the specific devices being used and the desired features. In general, if both the source and the display support DisplayPort, using a DisplayPort to DisplayPort connection will provide the best performance and compatibility. However, if one of the devices only supports HDMI, then using a DisplayPort to HDMI connection would be necessary. It's important to consider the specific requirements and capabilities of the devices being connected to determine which connection is better for the given situation. **

The purpose of an HDMI to HDMI adapter is to connect two HDMI cables together. This can be useful when you need to extend the length of an HDMI cable or connect two devices that are both equipped with HDMI ports but are too far apart to connect directly. The adapter allows for a seamless connection between the two devices without any loss in signal quality. **

No, there is no direct adapter from HDMI 2.0 to HDMI 2.1. HDMI 2.1 is a newer standard that offers higher bandwidth and supports features such as higher resolutions, refresh rates, and dynamic HDR. Adapting from HDMI 2.0 to HDMI 2.1 would require more than just a simple physical adapter, as it would need to support the additional features and capabilities of the HDMI 2.1 standard. It is recommended to use devices and cables that are compatible with the HDMI 2.1 standard for optimal performance. **

However, when connecting a device with HDMI 1.4 to a device with HDMI 2.0, the capabilities will be limited to the features supported by the HDMI 1.4 standard. **
