    HDMI output not working


    Hey guys, I have an ASUS s550C running windows 8 and my HDMI to my 32" RCA flatscreen doesn't work anymore. The cable works fine with the xbox, correct tv modes, but now as soon as I plug in the HDMI to the Ultrabook the Ultrabooks screen goes black and the tv screen says unsupported. What gives? I have tried extended, 2nd screen only, and all screen settings, 720/1080I etc. Ideas?

    Any chance your individual problems are somehow related? Did they both happen at the same time? Did you do something right before?

    I don't think they are related. I lost the HDMI feed a week or so earlier than the connection to the xbox. This laptop is also only 4 months old to add some context there.

    OK, thanks for that. Just wanted to make sure. You might want to add your systems specs as well because that may entice others to respond based on your known configuration.

    UPDATE: I missed the ASUS s550c so that should be adequate unless you can provide anything additional.

    There isn't anything more that I can think of, Newish unit bought off the floor. I am not a tech savvy guy so I keep it pretty simple.
