I used the following in the dsdt for my notebook to enable all outputs and iron out at least some of the artifact issues. But you have to keep in mind that a certain number of artifacts (the lines you describe) are even an issue on real mac's but as apple refines and releases new Intel Graphics extensions it will likely be resolved eventually.

 

Here are the relavent snippets from my dsdt (for reference, you will need to adjust and insert into your own dsdt):

 

            Device (IGPU)
           {
               Name (_ADR, 0x00020000)
               Method (_DSM, 4, NotSerialized)
               {
                   Store (Package (0x02)
                       {
                           "AAPL00,DualLink", 
                           Buffer (0x04)
                           {
                               0x01, 0x00, 0x00, 0x00
                           }
                       }, Local0)
                   DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
                   Store (And (Arg0, 0x07), DSEN)
                   If (LEqual (And (Arg0, 0x03), Zero))
                   {
                       If (CondRefOf (HDOS))
                       {
                           HDOS (Arg0)
                       }
                   }

                   Return (Local0)
               }

 

            Device (HDEF)
           {
               Name (_ADR, 0x001B0000)
               OperationRegion (HDAR, PCI_Config, 0x4C, 0x10)
               Field (HDAR, WordAcc, NoLock, Preserve)
               {
                   DCKA,   1, 
                           Offset (0x01), 
                   DCKM,   1, 
                       ,   6, 
                   DCKS,   1, 
                           Offset (0x08), 
                       ,   15, 
                   PMES,   1
               }

               Method (_DSM, 4, NotSerialized)
               {
                   Store (Package (0x06)
                       {
                           "hda-gfx", 
                           Buffer (0x0A)
                           {
                               "onboard-2"
                           }, 

                           "layout-id", 
                           Buffer (0x04)
                           {
                               0x0C, 0x00, 0x00, 0x00
                           }, 

                           "PinConfigurations", 
                           Buffer (Zero) {}
                       }, Local0)
                   DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
                   Return (Local0)
               }
           }

 

The

                            "hda-gfx", 
                           Buffer (0x0A)
                           {
                               "onboard-2"
                           },

bit is for the hdmi audio output.

 

Also for backlight control add the following to the end of Scope(_SB):

        Device (PNLF)
       {
           Name (_HID, EisaId ("APP0002"))
           Name (_CID, "backlight")
           Name (_UID, 0x0A)
           Name (_STA, 0x0B)
       }
