Fixing Scrambled,Stretched, or Wrong Resolution Laptop Display Problems

Recommended Posts

Some progress here)
I have successfully avoid problem of 16bit colors
I'm using Clover bootloader

So the recipe is:
Try to injecting EDID with clover, I have found that an editing DisplayProductID-717 causes wrong definition of LVDS. OS X shows it as an external display.
For this you must delete or return original DisplayProductID-717
And configure clover <key>CustomEDID</key> with your EDID
then
<key>InjectEDID</key>
<string>Yes</string>

That's it. This solves my problem with correct connectors and 16bit colors(gradients) on my ATI 5470m

Intel HD 4000 on Lenovo Y480, Mountain Lion:

 

Hey can you write a tutorial for installing Mountain Lion on Y480? My friend have lenovo Y480 also, with i7 3630QM, but never got QE enabled. If the graphics Injector option in clover is set to on, the laptop boots to an external display(and the display is scrambled). If the inject EDID and graphics injector option is set to on, laptop boots into a white screen with black lines in it. If the custom EDID key is specified in clover config.plist(with the injectEDID and graphic injector options on), then it simply boots as if graphics injector is off(no QE CI and normal resolution) How did you get there?

 

Thank you very much.

Hello

Thank you for this useful topic.

 

I have a problem with my HD 4000, Samsung NP550P5C , 1600x900

 

I followed this guide and i noticed i can get picture only using 01660003, but it was scrambled and i could see only 50% of my desktop)

screen-shot

 

Then i used doual-link patch and i get full picture , (using 0166000this time! 01660003 does not work and its like it doesnt detect doul-link).

 

BUT the problem is that i see a lot of Blue and green (sometimes red) pixels flickering and sparkling on my monitor :( also whole screen is darker than normal)

 

here you can see sparkling pixels :

Any idea please? whats my problem and how can i try to fix it?

Any help greatly appreciated.

                    Return (Local0)
                }

The important thing in this patch is that if you have your resolution smaller then 1280x800 you should have :

"AAPL01,DualLink", 
                            Buffer (0x04)
                            {
                                 0x00, 0x00, 0x00, 0x00

If your screen resolution is higher you should use:

"AAPL01,DualLink", 
                            Buffer (0x04)
                            {
                                 0x01, 0x00, 0x00, 0x00

After i applyed the edid override procedure all things were good. I used another laptop and connected with vnc viewer to my laptop and modified the edid file.

 my GraphicsCard :AMD Radeon HD 6570M

 

everything works, full graphics acceleration, but I can't control brightness because the display0 is detected as AppleDisplay in ioreg.

 

when I first added device id to ATI5000Controller.kext my laptop screen got dark after reboot using Eulemur personality

then I injected the edid through your guide and it worked .. but recognised as a VGA display 

DisplayProductID-717 :(also attached)

note : even with this file ... and the working screen .. I can't fine IODisplayEDID in ioreg but switchresX was able to extract it.

 

 

I tried patching the Eulemur personality which I'm using but with no luck ... this time no displays are detected.

I tried this and it works. But the only thing i am not getting at all is that whenever i use GraphicsEnabler=Yes, my laptop's diplay goes black/blank and shows nothing.


i somehow managed to capture the screenshot from the TightVNC acessing from the other pc.


In the Screenshot u'll see that it is recognized by the system, and also the graphics memory but there's no Display shown in the System profiler.


 


Please tell me what should i do to make the laptop screen working.

Using this procedure to fix a Mavericks installation on a Lenovo T510.

 

Question:  I cannot boot into the installer, but I can boot into 10.8.5 which is on the current internal hard drive.

Will this work to get the proper value for the EDID, or do I need to somehow get into Mavericks, would it change between system versions?

 

10.8.5 works great on this machine, QE/CI and everything.  Just 10.9 boots into garbage screen, or stays in console mode (no GUI).

So I thought maybe my EDID changed sometime after boot since it's the EDID is the same when the screen is scrambled and when it's normal, but that wasn't the case. So I still don't have any solution to my own problem.

 

If anyone is interested, here's a script I made to make the system report the EDID to the system log so you can view it in the Console (the OS X app). It'll read the screen's EDID continuously every 10 seconds after boot and put it inside the system log. So after installing it you'll be able to find out when it's scrambled and when it's not, or if it changes during or after boot (most likely not).

 

Usage:

 

- Use the terminal to cd into the "readedid" folder you downloaded.

- Write "sh install.sh" without the quotes.

- Write your password to give root access.

- Reboot until it's scrambled

- Reboot again until it's normal and compare all the EDIDs that's located in the console (search for "IODisplayEDID") and you'll most likely see two different EDIDs getting reported. The one that isn't being reported right now while the screen is normal is probably the faulty one.

 

Remember to uninstall it (do the first three steps as above, just with "uninstall.sh" instead) after you got all the information you need and reboot, otherwise it'll continue to report the EDID to the console every 10 seconds, even when you don't need it.

 

You can obviously read what the source code does by opening the files inside a text editor.

 

While my experiment didn't bear fruit for me, at least I practiced my bash scripting. Good luck everyone, hopefully someone will have use of this!

I think this post is very old but it kind of describes my problem. The hackintosh works okay under inte hd 4000 (with nvidia 720) only when connected to HDMI. if no HDMI connected I receive black screen.

 

I've been fighting for some days with this but so far I think I have arrived to a bad end.

 

So I got my EDID from windows:

00FFFFFFFFFFFF0030E4DB030000000000160103802313780A05F594585692281E505400000001010101010101010101010101010101FB1D56FC500016303020350059C210000019000000000000000000000000000000000000000000FE004C4720446973706C61790A2020000000FE004C503135365748332D544C54310006

 

I can only use ioreg -l connected to HDMI and then, the information provided doesn't come from the monitor from laptop, but from the HDMI monitor.

 

On top of that it seems that some data that I retrieved from windows is not accurate and may have wrong endian (Bytes seem to be ordered different) than in Mac.

 

At this point I'm stuck and I think I can't move forward by myself. Any suggestion?

 

I'm new to this forum and still learning a lot I sufferedto set up hackintosh in order to be able to use xcode without using VMWare. Any help will be more than welcome

Third update :)

 

I have put the configuration following the tutorial but still I get a black screen.

 

Now I played with the options of clover and I removed the inject graphics HD 4000, and now it "works", I can see screen but only on low resolution 1024x780. And there seems to not be an easy way to change it.

 

After this, I start to believe the the problem comes more from the Graphic driver than from the screen... therefore I will try to open a new post on the support area.

It sounds to me like you're not injecting the correct ig-platform-id.

UPDATE: Read my second post on the next page as I figured this out, but will leave this post here in case others are searching the same issues later...

 

Hey guys and Gals, 

Firstly, thanks for all your insight, time and hard work. Im new here as a member, but have been reading for about a year off and on. 

 

Now, weird issue. I have Host Toshiba Ultrabook U840W 21:9 1792 x 768 resolution (yes, thats correct res) running

Windows 8.1 pro x64, Dual Core, 6gb Ram (host)

VMWare WS 11+Tools and Un-locker 2.0.4 (should be titled enabler I think, the name suggests hacked when really, it just enables VMWare to load OSX into preset menu)

 

I have two guest VM's. Mavericks 10.9.5 (i think its .5) and Yosemite 10.10

 

PROBLEM

-Yosemite OOB VMDK install worked great, full screen resolution at 1792 x 768 with no tinkering required at all. Slow and unreliable when updated security patches are installed. Beamoff Tool solves most of the lag and speed issues. (BUT NO other available options available in display options-weird),

 

-Mavericks 10.9 VMDK install, Un-locker 2.0.4, VM Tools gets maximum 1366 x 768 as a pre-installed option in Display prefs. 

 

So, I love Yosemite, But the mavericks install leaves Yosemite wanting. Mavericks install is fantastically fast, stable and only has that annoying screen policing issue. Hence, until I get a faster Laptop, Mavericks will be my choice of VM [ for now :) ]

 

ATTEMPTED FIXES:

-SwitchResX: Continual "Not Installed' error and 'Need Reboot' etc that everyone gets attempting to create custom display settings.

-Contacted Stephane at SwitchResX (Basically told the issue is not with SwitchResX, but rather my Operating System, despite making numerous mistakes about what order I    was running the VM environment in. I.E kept stating that Mac OS X as a host is not supported by VMWare and other such silly statements. [ Reminder: I'm on Windows host ]

-This guide as well as a TonyMacX Plist edit in AppleScript etc.

-Uninstall_Re-install of all softwares

-Third Party SVGA Driver (Not recommended unless from a very treated source many online versions crashed a number of installs, Thanks goodness for VM software!)

- I used this guide to confirm EDID on Yosemite and BOTH VM's use the same Plist details as listed below.

 

They show up as the generic:

DisplayProductID" = 1815

DisplayVendorID" = 1970170734

IOService:/AppleACPIPlatformExpert/PCI0@0/AppleACPIPCI/display@F/VMwareGfx/VMwareFramebuffer/display0/AppleDisplay-756e6b6e-717

 

So my confusion is this, why does Resolution in Yosemite work work perfectly at 1792 x 768 OOB, with the same VMWare+Tools+Unlocker yet Mavericks 10.9 is stuck at 1366 x 768 despite Plist being the same in both VM Op's?

 

I think I have a case of working on something too long, and forgetting what i have tried and not tried etc. Maybe someone has a simple solution for this, but i know that with my 21:9 1792 x 768 resolution, its a challenge, BUT Yosemite knew straight away to use the Host settings?

 

Thanks ahead of time people, and just so you know, I am a helper too and contribute to posts (Toshiba) etc, so i will pay it forward. 

 

Cheers from Australia....

Shane

my IODisplayPrefsKey dose not have numbers it only value Ex 

 

"IOService:/AppleACPIPlatformEx$

 

any help ?

 

In case you haven't done so already, its advisable to >Open Terminal, >Maximise Terminal view window even so it stretches outside the screen view, Then do the 'ioreg -l' command. When the Terminal window is too small, it cuts of text (known as truncating) which is why you get the $ symbol at the end. If you see the $ sign, then you haven't opened the view enough...

 

Cheers....

Ok, so I cannot believe this myself, but then again I can when you think of the simple rule of "Downloadable images are altered sometimes maliciously and sometimes because the author thinks they are doing the community a favour, therefore, downloader beware" etc.


 


So, what I did to fix my issue, was a long route, but desperate times call for desperate measures. Ill try to make this simple and in point form. Bear with me, cause it sounds crazy, but it worked....


 


-I downloaded a trial copy of Fusion for MAC OSX, and installed that into my Workstation 11 image of Mavericks hosted by Windows 8.1 pro. This is the image that WS11 would not Auto Adjust to my desired 1792x768 res..with me so far? Good...


-I copied Mavericks OSX App from my 2009 Intel iMac to USB, then to Windows Desktop. From there, I dropped the Mavericks Mac App into the Mavericks VM desktop....Still with me....Good


-I then dropped Mavericks app into Fusion and mounted and installed it just to the point where it creates the VM Folder in Documents. Remember, this means that what I did, was create a new Mavericks OSX VM, inside my running Mavericks VM Documents folder. 


-I then cut and pasted the new Mavericks VM Documents folder from the Documents folder inside my Mavericks VM, to my Windows Host Documents/Virtual Machines folder. Now I had the base install i needed to "open a new virtual Machine in Workstation 11"


-Then, I shut down Mavericks VM, and proceeded to "Open Virtual Machine" from Workstation 11. This is the image i just created, then cut and pasted to windows host VM folder in documents...


-This began the fresh install of Mavericks 10.9 in Workstation. 25mins later, I had a fresh, untouched Virtual Machine....Voila..


 


IT GETS BETTER


-As soon as i installed VMware Worksation Darwin 7.1.1 tools, and rebooted, presto, FULL 1792 x 768 Resolution in full screen mode....!!!


 


I know this post will confuse people, so feel free to contact me and Id be more than willing to assist if I can. 


 


Big lesson learned and could have saved me a LOT of Plist editing, internet searching and Forum reading by just using an untouched Mavericks App from the get go. BUT, I couldn't find the tools to create an ISO from the Mavericks App I had, and didn't know Terminal Script to create bootable USB's, if that would have even helped anyway....


 


Cheers everyone, and I hope this helps someone...


Shane


:yes:   :D   :P   :lol:   :)   :w00t:   :D   :drool:   :thumbsup_anim:   :D   :rolleyes:   :rofl:   :hysterical:   B)   :rolleyes:   :wink_anim:   ;)


For those requiring links  (I know I appreciated people sharing them when I was learning)


- VM Workstation up-gradable Trial Download Here: https://my.vmware.co...orkstation/11_0


- VM Fusion 7 up-gradable  Download Here: https://my.vmware.co...ware_fusion/7_0


- VM Ware Tools AKA Darwin Here: http://www.insanelym...os-x-darwiniso/


- Mavericks 10.9 App, possibly available through Mac App store, but may have to get it of your own Mac like I had to.....Again, beware of internet VMDK images etc, as you may get a maliciously coded one, or innocently modified as   mine seemed to be, which meant I could not get desired resolutions. Who knows what else was lurking right? 


-------------------------------------------------------------------------------------------------------------------------------------------------------


 


Lastly, I will state this. Although having Mavericks running is VMware is great, I will say that it is more so just a prrof of concept. Meaning, that there are just too many features that are not available and that compromise is just too much to make it a go to system. 


 


There is no iMessage, Maps crashes, Photobooth cannot detect Camera, you cant run Open GL Intensive graphics programs such as Photoshop, and even music such as Garage band and Logic ProX wont run. In my opinion, these features are the reason people want mac. I.e. Graphic, music, stability, iMessage, iCloud etc...


 


*Please note my machines specs are Toshiba U840W PSU5XA-001006, i5-3317U CPU @ 1.70GHz, 6GB Ram,  as am sure some can get 'some' of these features working on better spec's Laptops (maybe....)


 


Again, its nice to know it theoretically works, but really, its just a glorified web browser, and even then the video playback and graphics suffer....


 


My next project may be a Metal Install, but again, the amount of tweaking required is above my patience level for now, and I am up against some struggle only having Intel Centrino N2230 wi-fi card installed. Even if i find a Kext or learn how to create a DSDT for my laptop, its still an uphill battle...But hey, i may just choose to go upstream...
