Hi there, a couple of days ago I suddenly noticed white dots randomly appearing on my MBP’s display. See:
https://youtu.be/nj5WNlZksUw It’s even more noticable on dark areas. My first thought was GPU-related. But since my Mac has two of them (Intel Iris + GeForce 750M), I downloaded gfxCardStatus to switch between them and to my surprise, the issue persists. Resetting SMC and PRAM didn’t help. Today I connected the MacBook to another display via HDMI and while I’m still getting these flickering dots on the MBP, the screen is perfectly fine on the external display. Looks like the display is affected. But since 400 dollars for a new display is a lot, I’d like to see what you guys think. Have you ever had this issue? Could it be anything else than the display? Thank you.
Hey, I had the same issue on Macbook Pro 15" late 2013. I unscrewed the bottom case, disconnected the display ribbon cable, reconnected it and the problem went away! In my case, the problem started after a heavy object fell on my laptop (ouch) so maybe it was the impact of the collision that moved the cable. It’s worth mentioning that the cable seemed to be seated just fine on its connector, but apparently it wasn’t. TL;DR: Disconnect and reconnect the display cable.
Same issue on an early 2013 15" MBP. Just noticed that if I applied pressure to the hinge above the ESC key that the flickering pixels and lines went away. First time I have been able to “fix” it intentionally and I’m not sure it will last. It has only done this 3 or 4 times since I purchased it and it has been about a year since it last malfunctioned.
Did you solve the issue? I have the exact same model as yours (Retina Mbp 15 w/ 750M) and just noticed my screen is doing the same.
I don’t know where I found this, but applying pressure on the frame above the first few F1 keys has fixed my problem. I think that it did something to the underlying cable. I hope this can help you.
Wow, this just started happening to me as well. No impact or anything like that happened with my display either, I’m wondering what the problem is. I really hope it’s a software issue. :/
I got the same Issue! It’s a MBP Retina 15" 2014. Flickering Pixels all over the screen. I think they are mainly white and therefore mainly visible in darker areas. I tried El Capitan and Os Sierra. It didn’t change anything. They are permanently there, so I think it’s a Hardware (Screen?) issue. Maybe a isolation problem? bad connectors? can’t really find anything about that, it seems to be a rare problem. please help!
Hey! I’m experience the same problem. I’m on OS 10.10.5. Are you still having problems or how did you get it fixed? Please help! Best regrads, Johan
Same problem here. I am positive it’s either a display problem or a connector problem. If I connect my Cinema Display, the flickering pixels don’t appear on the external display, yet they’re still visible on the MacBook Pro’s display. The situation doesn’t change regardless of which graphic card I use, Iris Pro or 750M. Has anyone attempted to fix this by himself, or did you contact Apple’s assistance? How much did it cost?
I’m having the same problem after have sent my MBP to Authorized Apple Assistance to get it cleaned internally and to get its sound system fixed. I’m gonna ask them to fix this for free as it wasn’t that way before I send my machine to them.
Hi Guys, I saw this problem pop on my Macbook Pro 15’’ 2014 Dual Graphics model. It is only visible when the Discrete GPU is in use. I didn’t fairly notice this issue earlier. I have not attached an external unit yet, but it feels like this is a graphics card issue. For anyone coming here from macOS Mojave 14.4, try gfxCardStatus and see the information.
Lads, how the same issue after opening up my macbook for some routine cleaning.
After reading banshee_bob’s point about pressing the keys down i assumed it was some sort of pressure issue.
So i took off the bottom plate and re-installed it making sure this time all the screws were in the right place and that seemed to solve the issue.
I have encounter the same issue with flickering white pixels. Anyone has a new solution apart from the abovementioned?
I recently experienced the same issue, it happened after I did a routine clean up of the ventilators. All the pervious suggestions: pressure points, gfxCardStatus, software updates, etc did not solve the issue. When I use an external monitor the issue does not persist, which makes me think that it is input/output or motherboard related. Would anyone have a potential diagnosis? Is it that I accidentally short circuited something while cleaning? Any tips are much appreciated.
