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.
