Distorted screen using integrated Intel GPU
I'm having problems with the dedicated GPU on my Macbook Pro 15inch which whereby I'm not able to boot beyond the Apple logo into the Mac OS screen(having distorted screen as well).
Fortunately, after I followed the dosdude guide about gpudisable on dosdude.com/gpudisable, I am able to configure my Macbook to use the Intel GPU. I tried connecting it to an external display but failed to detect any signal, I assume this is normal since the dedicated GPU is faulty.
However, the distorted screen issue is still there. I have attached a few photos regarding the issue.
- The screen colour will turn red when the background colour is black. This is specially obvious in the Single User Mode.
- If there are any windows opened, there will be linings surrounding the windows.
I am now wondering whether the issue is on the logic board or the LCD. I can replace the LCD but I'm afraid that the logic board is the culprit here.
Any clues on how should I troubleshoot on the root causes?
Updates: Added image of LCD connector
