I find this comment very misleading. Yes, it *may* work, but HDMI actually does *not* handle long runs very well at all. Some people have had success with 40-50ft runs, but this generally requires high quality, thicker cable and a "strong" source device which plays nicely with display. It also requires a bit of luck too from what I've read. Also keep in mind that it's more difficult to transmit 1080p signals over longer distances than it is to transmit 1080i or lower since they contain more information which requires more bandwidth.
Here's an article which may help:
