Gradient Issue With AMD Radeon HD 7650M Sony Vaio SVE1712BCXB

passmaster16 · June 8, 2014

I'm new to the OSx86 scene and trying to get a retail Mavericks 10.9.3 build running on my Sony Vaio SVE1712BCXB. CPU is a Intel Core i5 3210M (2.50GHz) and video card is an AMD Radeon HD 7650M. The internal display is a 17" LCD with 1920 x 1080 native resolution. I am currently booting Mavericks using Clover R2689 from a USB drive. From my research I've found that many people have had trouble getting video output on the LVDS of these Sony Vaio E series laptops equipped with the Radeon HD 7650M. I've managed to get the card recognized with full QE/CI acceleration on all three outputs (LVDS, HDMI, and VGA) using my dumped VBIOS and a modified Pondweed framebuffer. My issue at the moment is that gradients are being handled poorly on the LVDS. It's very apparent in the Chess app as well as the test here: http://www.lagom.nl/lcd-test/gradient.php

Since the gradients are handled fine on HDMI and VGA, my thought is that there is something wrong with the EDID recognition. However when I tried to modify the first byte of the basic params from 80 to 90 per freeuser16's suggestion here http://www.insanelymac.com/forum/topic/277042-amd-radeon-hd-6650m-graphics-enabler-dsdt-hdmi-audio-acer-aspire-7750g-2674g50mnkk-gradients-fixed/page-28?do=findComment&comment=1933143 and inject a custom EDID via Clover, I get no display output on the LVDS, just a black screen with no backlighting or anything, like its turned off. If anybody has any suggestions on how I might be able to able to resolve this problem, it would be greatly appreciated. My decoded VBIOS is below. EDID is also below and the output from Windows is identical to DarwinDumper. Attached are Clover config.plist and unmodified DSDT dumped from Windows.

@passmaster16 could you describe how you managed to dump your video bios?... As far as I know switchable graphics does not work on hackintosh.

passmaster16 · June 8, 2014

@vlad I used the Intel Flash Programming Tool (fptw64.exe) on Windows 8 to dump the entire bios. The vbios is contained within the main system bios. The Intel tool will dump everything then just look for the 64-65kb rom file which should be the vbios. The Intel tool was the only one that was successful for me. I was unable to dump the vbios using GPU-Z or AIDA64, both on Windows.

Regarding the switchable graphics, this machine has a severely locked down bios but it doesn't matter because even with a modded bios, there is no way to get output from the HD4000 card on this system http://www.insanelymac.com/forum/topic/284997-enabling-qeci-on-sve1711x1eb/

Now I'm wondering if my issue can be due to the fact that I changed the encoder from 00 to 01. With LVDS encoder set to 00, I get output similar to the image in this thread http://www.insanelymac.com/forum/topic/294018-toshiba-l850-7670m-lvds-problems but with it set to 01, the output is much better with exception to the gradient issue. Is the gradient issue due to 16-bit color vs 32-bit color set by the encoder?

Check here how to edit your custom EDID, you must use Serial number from Mac, not just changing the Basic Params and Chroma Info. I am not able to inject the EDID with Clover, I use DisplayMergeNUB.kext instead. The black screen can be fixed with the Dual Link patch.

Hey Trucker, I was hoping you'd stop by this thread as I know you have vast knowledge on this issue. I followed your steps in the post http://www.insanelymac.com/forum/topic/277042-amd-radeon-hd-6650m-graphics-enabler-dsdt-hdmi-audio-acer-aspire-7750g-2674g50mnkk-gradients-fixed/?p=2023266 and used FixEDID to generate a DisplayMergeNUB.kext. I used my original dumped EDID with FixEDID to generate the kext using an Apple profile. I used MacBook Pro Display profile since it is 16:10. I then modified the basic params of the info.plist in the newly generated kext to the original EDID with exception of the first byte, changed to 90 vs 80, and fixed the checksum. The gradients are gone even with switching the LVDS encoder back to 00. Thank you for your help and pointing me in the right direction!

Two more questions:

1.) In the FixEDID app, there is a display class and override display class. These are both set to AppleDisplay but I noted that they can be changed to AppleBackLightDisplay. What is this used for and is there any benefit to changing the kext to use it? Would this provide the ability to control brightness on the LVDS because I don't believe I have that capability right now?

2.) I know that VGA really isn't supported by Apple anymore but I noticed that while VGA will output to my Dell 24" monitor, the highest resolution I can output from the VGA port is 1280x1020. The monitor is capable of 1900x1200. Just curious if there is anything I could do to correct it like patch the framebuffer? I had to change the encoder from 10 to 08 to get it to output anything so maybe I'm doing something else wrong that is affecting the resolution?

Thx again,

Josh

Using encoder 00 enables proper Display sleep for me, otherwise i get just black screen with backlight.

1. Using AppleBacklightDisplay doesn't provide the ability to control the brightness with the slider from System Preferences/Displays.

2. I haven't tested this but in theory you can try this.

Connect your VGA Display, Use FixEDID to create the Display Override file for the VGA Display (when you open FixEDID, choose your VGA Display and previously saved EDID.bin, edit/ choose only inject EDID unpatched /edit, than click Make and the folder with the VendorID and ProductID of the VGA will be created on the Desktop). There is a tutorial here on the forum, something like Advanced EDID injection, look for it, you will find there how to add custom resolution for the VGA by editing the Display Override file. When you are done, copy the folder to /System/Library/Displays/Overrides, reboot and you should be able to select your desired resolution.

Thx Trucker, I'll give it a shot. Do you have a link to a good guide for enabling brightness control through pref pane as well as my function keys (fn + f5/f6)? I wasn't sure if the procedure is different on the radeon cards vs the on board intel ones?

Trucker MK · June 10, 2014

No, i tried the PNLF patch from DSDT Editor plus some other patches but none worked. My FN keys work even without the FN Keys patch from DSDT Editor, try it if you haven't tried yet.

Trucker - do you have the brightness slider showing in the pref pane without applying the PNLF patch? When I apply the PNLF patch to scope _SB in the DSDT, it breaks the EDID that's being merged by DisplayMergeNUB.kext, making the display unusable again. It does make the slider show up but the slider doesn't appear to function either, no change when adjusted. I could deal without the function key control for brightness if the slider worked. Oddly enough the function keys work fully for audio using the VoodooHDA driver.

Trucker MK · June 13, 2014

Make another DisplayMergeNub.kext but this time choose AppleBacklightDisplay. I do have it but because Clover is kinda Auto Applying the PNLF patch even though I haven't choosed so in my config.plist

I actually tried this yesterday. I used FixEDID and set display class to AppleDisplay and override display to AppleBacklightDisplay. IOReg shows AppleBacklightDisplay for display0 but still no slider in pref pane. Any other ideas?

hey you are hope now passmaster16

sorry for my bad english..

i have sony vaio too with ati hd 4570 graphics card.

(in your thread you have clarified that with laptop lvds you some how enabled full qe/ci and everthing.)

that is hope for me but how??

now a little back ground of my issue.

with coustom dsdt i somehow enabled full qe/ci etc but on vga(external mon). on LVDS i got black screen. i use mavericks 10.9.3, chameleon.

here is vbios (in yours i have noticed senseid) but in mine it hasnt

please guide me how can i solve my issue.

thanks in advance bro

I followed your steps in the post http://www.insanelymac.com/forum/topic/277042-amd-radeon-hd-6650m-graphics-enabler-dsdt-hdmi-audio-acer-aspire-7750g-2674g50mnkk-gradients-fixed/?p=2023266 and used FixEDID to generate a DisplayMergeNUB.kext. I used my original dumped EDID with FixEDID to generate the kext using an Apple profile. I used MacBook Pro Display profile since it is 16:10. I then modified the basic params of the info.plist in the newly generated kext to the original EDID with exception of the first byte, changed to 90 vs 80, and fixed the checksum. The gradients are gone even with switching the LVDS encoder back to 00. Thank you for your help and pointing me in the right direction!

Two more questions:

1.) In the FixEDID app, there is a display class and override display class. These are both set to AppleDisplay but I noted that they can be changed to AppleBackLightDisplay. What is this used for and is there any benefit to changing the kext to use it? Would this provide the ability to control brightness on the LVDS because I don't believe I have that capability right now?

2.) I know that VGA really isn't supported by Apple anymore but I noticed that while VGA will output to my Dell 24" monitor, the highest resolution I can output from the VGA port is 1280x1020. The monitor is capable of 1900x1200. Just curious if there is anything I could do to correct it like patch the framebuffer? I had to change the encoder from 10 to 08 to get it to output anything so maybe I'm doing something else wrong that is affecting the resolution?

Thx again,

Josh
