Hello, I have an ASRock Z87 Extreme4 Motherboard in my computer. The IO panel has several in and out choices. I have my Monitor connected via the DVI socket and my LG TV connected to the HDMI out. Now, my question is how can I use the HDMI in connection?

 

I have an Android TV box with HDMI out that worked fine on my TV last time I used it (about 6 months ago) Today I thought I'd try to run it through my computer to update it and maybe pass it along to a friend. So when I connected everything I could see the extra display in the Display Settings but it says there's no signal.

 

I downloaded the A-Tuning utility which turns the HDMI on and off using "Alt C" but when I do this the screen goes black like it's switching but then returns to my PC screen.

 

Is this just the way these Android boxes work or am I doing something wrong?

 

If this is a restricted subject please disregard and delete my post.

 

Thank you for any help.

windows key + P   and you can either duplicate the screen or extend.  you probably want to do the extend that way both monitors so you can do different things

 

Duplicate just puts the exact same thing that's on your 1st screen to your 2nd screen.

I think you misunderstood my question. I have those options in my display properties. I duplicate screens so that I can watch media from my computer on my 60" LG.

My query was how do I use the HDMI input in the motherboard of my compute to access my Android box on my computer monitor.

I'd look very closely at the specs on that MOBO.  It would be unusual for it to have an HDMI INPUT but I guess you've got one.  Somewhere in the BIOS, as it is system and not software dependent, is the setting for all the ports detected and if not detected or not supported by that version of BIOS.  A system manual might lead to some hardware settings too.

"...try to run it through my computer to update it..."   I thought the HDMI port on a computer is output only.  I guess there are computer HDMI input ports now?

Yes, Multimedia integration is becoming more flexible these days.

Blackstar, the most likely thing I can see is it looks to me like the HDMI In uses power from the HDMI, as it says it works when the computer is off, and the manual gives a reminder to use external power for any HDMI adapter if one is needed for an external device.

Maybe the Android TV Box device either doesn't implement the +5V HDMI supply, or doesn't supply enough current. If the Android box also has a Micro USB port, maybe you could try an MHL lead? There's an MHL compatibility check here:

Thanks for the ideas Guys. Never thought of going to the site and downloading a user manual... (I've been working a lot of 12 hour night shifts... gotta have some excuse ;) )

 

I have to check the setting in the Bios.
