I've already purchased my LCD( 8.9inch B089AW01) controller with HDMI input to be used for my BeagleBone Developing Station.
You can check the item I bought(http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=360702343124&ssPageName=ADME:X:RTQ:US:1123) and maybe look for similar controller for your particular LCDs if you want to build a similar station :)
So now I have to wait for about a month(yes, a month... u.u) to receive my controller and start building my developing Station
In the meantime I'm doing a weir Diagram showing how the BBB Developing Station is gonna be connected, some parts are still missing, but let's call it a draft by now...
May the bone be with you...
