The part about HDMI that is complicated is its licensing . HDMI uses a method of encoding call off HDCP — also known as mellow - bandwidth Digital Content Protection . The goal of HDCP is to foreclose a signal from being routed elsewhere , so it ’s essentially an anti - plagiarization chemical mechanism . HDCP works like on-line encoding in that itperforms a key exchange between a source machine(your plot cabinet , Blu - ray player , Roku , etc . ) and whatever the display is .

What To Do When HDMI Isn’t Working On Your TV
In those cases where the handshake does n’t play out how it should , and you ’re certain there is n’t just a lax cable , there are multiple , mere solutions to the trouble . Almost all of them are but various ways of crap the two devices attempt the handshake again . For this reason , the primary root — and the first thing you should always try — is to plainly disconnect the HDMI line from the author twist , wait for one minute , and plug it back in . It ’s an underwhelming troubleshooting method acting , but it forces lots of important operation to restart and often ensue in a successful handshake .
If that does n’t work , the next thing to consider is changing the boot sequence . So , if you turned on the display before your HDMI seed , try turning both off and then powering them on in the polar order . This is an extremely common solution for people with HDMI sources join to a home theater system or an audio / video receiver . In many cases , the fiat in which these gadget are powered on will dictate the success of the handshake .

If it ’s not work , it might be an government issue with the twist ’s HDMI interface or the HDMI cable . It ’s also deserving assure if the source gimmick is connected to mogul . It might seem silly , but it ’s a fairly coarse reason why the No HDMI Signal mistake might look .
If neither of those solves the problem , one last , plebeian matter to try is to control resolving power options . Most goggle box are saucy enough to adapt to any declaration within their capabilities , but some equipment that send video to a TV can be bothersome in that attentiveness . This is a big job for PCs , for object lesson , since they ’re unremarkably subject of output video recording in a blanket variety of resolution than an Apple TV or Roku would be . So , if your outputting equipment gives you manual control over its display resolution , consider place that to auto , or clean your television receiver ’s best resolution . If none of these thing solves your ' NoHDMISignal ' military issue , chances are there ’s something incorrect with the cable or the devices ' ports , meaning you ’ll need a replacement .
