This notebook has the same spec as Acer aspire S5 ultrabook (the same processor, resolution, gpu etc.)
13.3" LED (1366 x 768) Intel HD 4000, 8GB DDR3, Wifi Atheros AR9285, Li-Polymer, 3rd Gen (Ivy Bridge) Intel i5-3317U Processor (3M Cache, u 2.60 GHz), 128GB SSD
Something is wrong in Samsung because no one can run Intel HD4000 on that.
Below is my DSDT - in that configuration - only HDMI works - internal LVDS not working.
I don't know where is the problem, trying also automatic EDID in new Chameleon posted on insanelymac but also not working.
Tried other device-properties but only on ID=3 i can see anyth in HDMI, never on LVDS.
On HDMI acceleration works good.
