=What is HDMI?=
<p>This is <b>H</b>igh-<b>D</b>efinition <b>M</b>ultimedia <b>I</b>Interface is an interface from both uncompressed video data and audio.<br>
There are several standards of HDMI as this has improved over time. The point to be careful on is that the connection points may meet some of the these HDMi V*.** but not all.<br>


==How does the Linn DSM handle HDMI?==
The most Linn DSM products, with exception of Selekt ARM, come by default with HDMI switch devices. <br>
:* <u>No HDMI input selected</u>: If you are not listening to an HDMI input then the last HDMI input selected Audio and Video are "passed thru" to the HDMI output. This will allow you to listen to an audio only source, such as Radio, and watch and listen to your Satellite receiver on your TV.
:* <u>HDMI input selected</u>: If you then select an HDMI input on your Linn DSM then audio is <u>redirected</u> to the Linn DSM speakers. Now the HDMI source, e.g. Satellite reciever, audio is only playing from the Linn DSM speakers
:* <u>Linn DSM in Sleep/Standby</u>: You can configure in Konfig that when the Linn DSM is in Sleep/Standby mode then this will <b>NOT</b> thru the Audio & Video. In most Tv's this will sense that there is no HDMI and put the Tv into Standby after a few minutes. 



 
==HMDI 1.4==
This is supported by all Linn DSM products and supports up to 1080p resolution.

==HDMI 2.0==
'''HDMI 2.0''' is the HDMI standard that supports 4K. 
This means that the HDMI 2.0 connections can pass a lot more data than HDMI 1.4 and therefore allow higher resolution video and audio capabilites.

Majik, Akurate & Klimax DSM products with HDMI 1.4 boards can be <u>upgraded</u> to HDMI 2.0 capability.<br>

The Selekt DSM is supplied with an <u>[[HDMI#ARC_-_Audio_Return_Channel|HDMI ARC]]</u> input only but can be upgraded with an <u>[[Selekt_DSM_Cartridges#SELEKT_HDMI_SWITCHING_MODULE|HDMI Switching module]].</u>

The Sneaky, Sekrit & Kiko products use HDMI 1.4 and are not upgradable.<br>

==HDMI ARC==
:HDMI <B><u>A</B></u>udio <B><u>R</B></u>eturn <B><u>C</B></u>hannel is the audio returned from the same HDMI cable feeding A/V to the <u>television</u>.<br>
:This is only supported on the [[#HDMI_2.0|HDMI-2]] board, on the [[Selekt_DSM|Selekt DSM]] and on the [[Series_3|Series 3]].<br><br>

:This input can <u><b><i>ONLY</i></b></u> be used with a <u>television</u>. If any other HDMI source is connected to this input then no audio will occur. (The HDMI ARC communication is different to standard HDMI communications)<br>

:This HDMI ARC input is declared as a seperate input on the Linn DSM/HUB control. This can be set to automatically switch to this HDMI-ARC input when you have just switched on your television. More information on how to set this up are in the <u>[[Konfig_Manual#HDMI|Konfig manual]]</u><br><br>

:General limitations with ARC are that it doesn't communicate with the playback device, in this case the Linn DSM, what Surround formats that it supports, if any. You need to check within the TV setup that the HDMI-ARC connection will only output in a format/codec that the Linn DSM will support. (2-ch/stereo PCM for a standard Linn DSM/HUB and 5.1ch Surround sound for one with a Linn Surrond module).
