What is the sense to name it "HD Graphics" or "HD 3000" if I see deviceID=0x106 that corresponds to Apple's driver HD3000?

For Sandy Bridge, the framebuffer is AppleIntelSNBFramebuffer.kext. The property is AAPL,snb-platform-id. To ensure the HD3000 framebuffer loads, inject device-id 0126. Required IGPU/GFX0 dsdt injection:

For macbookpro8,1 (LVDS, DPx3)
"device-id",
						 Buffer (0x04)
						 {
							 0x26, 0x01, 0x00, 0x00
						 },
						 "AAPL,snb-platform-id",
						 Buffer (0x04)
						 {
							 0x00, 0x00, 0x01, 0x00
						 },


For macmini5,1 (DPx2, HDMI)
						 "device-id",
						 Buffer (0x04)
						 {
							 0x26, 0x01, 0x00, 0x00
						 },
						 "AAPL,snb-platform-id",
						 Buffer (0x04)
						 {
							 0x10, 0x00, 0x03, 0x00
						 },

@toleda: did you activate the VBios patch? When I was booting with CloverEFI that was all I needed to get 1920x1080. Now booting in UEFI mode I need the CsmVideoDxe driver as well. I don't need to set the resolution on refit.conf.

If you're using CloverGrowerPro you can check like this:

LoadVBiios results in a black screen on boot. Boot hangs with CsmVideoDxe. I have not gotten to CloverGrowerPro. I'm still using Clover/USB. To boot off USB, I select USB UEFI/Clover in the Asus BIOS Boot Screen (1440p), get the Clover UI at 1024x768, select the boot volume and hope for a Desktop. I tried the time=0 to avoid Clover UI and that fails to get to the Desktop as well with the same issue.

I did some testing.
it always set the right 1080p res on both hdmi and dvi and i dont have to replug anything.
boot logs attached.

Thanks for the tests. Your logs say:
0:532  0:012  SetScreenResolution: 1920x1080 - already set
and
0:543  0:012  SetScreenResolution: 1920x1080 - already set

Nothing about Modes, interesting.
Do you use refit.conf/screen_resolution 1920x1080?
If not, what config are you using?  EDID? VBIOS?

Please, do not mix resolution in Clover GUI and in OSX desktop. There are two different world with different drivers.

That is the point and the problem I'm asking for help to solve. All Clover benefits are useless to HD4000 users if Clover doesn't successfully boot to the Desktop.

I read it and i dont know how are u booting.
Its UEFI with CSM disabled or enabled ?
If u try with CSM disabled and its not working then plz try updated " Intel® PCI Accelerated SVGA BIOS 2158 PC 14.34 (11/23/2012) "

Using guide i posted on link above or let them do it for u if u are not sure how to do it.

Regarding the problem theconnactic discussed of getting to a 1080p (HD4000 HDMI) or 1440p (HD4000 DisplayPort) Desktop with Clover UEFI, some additional information:

My log shows the problem:
0:318 0:178 Available graphics modes for refit.conf screen_resolution:
0:318 0:000 Curr. Mode = 2, Modes = 3, FB = D0000000, FB size=0x3FF0000
0:318 0:000 - Mode 0: 1024x768 PixFmt = 8bit BGR, PixPerScanLine = 1024
0:318 0:000 - Mode 1: 640x480 PixFmt = 8bit BGR, PixPerScanLine = 640
0:318 0:000 - Mode 2: 800x600 PixFmt = 8bit BGR, PixPerScanLine = 800
0:318 0:000 SetScreenResolution: 2560x1440 - not found!
0:318 0:000 SetMaxResolution: found best mode 0: 1024x768 - set

reFit selects 1024x768 which my monitor does not support.  A huge Apple logo shows up (wrong resolution) and the Desktop appears with multiple images.  An unplug/replug works 50% of the time with HDMI and 10% or the time with DP.  Usually a reboot is required.

Chameleon with GraphicsMode boots successfully every time to 1080p and 1440p. There is no option in my P8Z77-I Deluxe BIOS for CSM.  Boot hangs with Clover/CsmVideoDxe installed.

I boot Clover/UEFI, no CSM.  Current installed Intel firmware supports 1080p and 1440p as the BIOS setup menus support the native monitor resolutions.

Is there a way to add modes for 720p, 1080p and 1440p to refit.conf screen_resolution?  Other suggestions?
