What I want to use it for is to display the output from my Denon A/V receiver. I have a front projector and don't want to turn it on just to be able to see the screen for Pandora, when playing a DVD-Audio/SACD disc, when checking/adding timers on the DVR, etc. It's hard on the lamp to fire it up on a front projector just for a short amount of time then shut it down. If I could get an HDMI signal from my Denon A/V receiver into a device like this I'd be able to do the misc things I want to do without having to fire up the front projector. In addition I could use the BluRay player on trips (dual purpose).
I tried to find something like a tablet that would accept a HDMI input but haven't found of one of those either. Either a tablet or portable BluRay player that accept an HDMI input would work fine for what I need but I'm not finding either one. Putting a computer monitor on my A/V rack is too big and bulky, not finding one of those small (e.g., 10-12" 16:9 diagonal) that accept a HDMI input.
I know this is a strange request but I could see people wanting an HDMI input on a portable BluRay player or tablet to display pictures from a digital camera via HDMI or even cell phone cameras via HDMI on a bigger screen.
