Hardware Why HDMI turn off?

[Rambytes]

Little question about the HDMI port of the WiiU. Why each time I turn on my WiiU my television detect a "new" hdmi input and ask me to switch?

All my other device, when I turn on these device my television never ask me if I want to switch to the HDMI port of the device, only the WiiU.

In the list of my "connected" device, if the WiiU is off, it's like the WiiU disconnect the HDMI, so it become unavailable on the TV.

So, there is a way to always keep the HDMI when I turn off the WiiU?

What TV do you have exactly? It could be a possible bug in the TV's firmware.

Try downloading the TV's latest firmware and install it to see if it fixes it: http://www.lg.com/us/support-product/lg-47LK520

yes I have the latest one....

I know if I unplug the HDMI cable from any device, and I connect again, the TV detect a new input and ask to switch to this port. But my PVR, my PC and my Western Digital Live Player never do this when I turn on the device, only the WiiU.

Hard to explain because my english is not my native language, but hope you understand.

I see. Sadly I've done all I could to possibly fix it. Maybe someone else on here can.

I think that the wiiu shutdown completly the hdmi port, so when I turn on the WiiU, it's like a new connection for the TV and that's why my Tv ask me to switch to this port.

That's what i'm thinking...

I would say that's perfectly normal behaviour from the WiiU and all your other devices are behaving out of the norm. Seems to me like your other devices are still powered, even though they are switched off. That's a waste of energy, in my honest opinion.

Agree with that... I've just found few second ago that my WD Tv Live Player is off, but the "optical" output still on!!! WTF?!?!?!?

It's like the WiiU is the only one that shutdown ALL the component to save energy!

Most HDMI output devices don't turn off completely because some HDMI display devices cannot automatically redo HDMI handshake without a hard reset. In that case that'll result a black screen.
