I have an HDMI input on my HP touch smart 600-1050UK desktop and I am wondering if I can convert this into an HDMI output so that I can connect it to my home Cinema.
Yeah this does seem like a stupid question but I'm asking the same thing. I would like to add a tv to my tv via hdmi. Long story why but it would work for me.
If you scroll half way down it mentions the HDMI port cannot be used for output.
You might be able to get a USB powered adapter to output to another screen - but there are limitations of resolution - and apparently they don't work so well.
