Mountain Lion UI Lag on rMBP !!! (Let's Make this thread serious and hope for a fix)

I can almost certain you are wrong, as I do not have an LG screen, but do have lag.

How do you now if you have an LG screen?

Do a Google search. There are tons of writeups about how to identify your screen.

I have samsung and I have lag.

@Erno12

Open terminal and type:

ioreg -lw0 | grep \"EDID\" | sed "/[^<]*</s///" | xxd -p -r | strings -6

If your display code begins with "LP," it's an LG display, if begins with "LS" it's a samsung

I now Google! I tried this site

http://osxdaily.com/2010/07/28/find-out-what-model-lcd-panel-in-your-imac-macboo k-macbookpro/

It just came up that I have a Color LCD (which I now), but no model number. Perhaps you do have a better idea (obviously you have already done it sometimes)😉?

Thanks! This worked better for some reason (I am not used to terminal)! It starts with LSN, which means I have a Samsung display. I found the 10.8.2 update made the lag on my screen better initally, but after a while it was much of the same. although not so bad as many others experience.

Me too.

I could only that

$ ioreg -lw0 | grep IODisplayEDID | sed "/[^<]*</s///" | xxd -p -r | strings -6

Color LCD

and no any other info come out...

Same here, samsung display and lag.

mountain lion 10.8.2 did make things a little smoothier but is laggy anyways

I am also only seeing "Color LCD"; no further identifying info. But this afternoon, strangely, all the lag disappeared... UI is now silky smooth. I have no idea what happened; I've not updated or installed anything. Anyone else experience this?

Is that even in apps like mail? The lag is very consistent in that for me.

Any news on this? I'm experiencing massive scroll lag in Chrome and Safari.

Someone said that he will bring his laptop to service and will claim to Apple about that, and he promised to share with us all news...I'm wating news...

Sorry guys,

unfortunately I have no news yet. The complete hardware test didn't detect any troubles. So tecnician got in touch with apple to find a solution. When I have further news I will post it.

Dear All,

I have the same problem since yesterday night... Diablo 3 has always run very smoothly in 1920 and now it's just laggy, as well as OS X interface...

I've reset SMC and PRam, force the nVidia, installed nVidia drivers update, disk utility, etc... nothing!

Nothing has change between 5pm and 10pm yesterday and my computer was running perfcectly since I received it 2 months ago...

Tomorrow I'll call the Apple Care and hope for the best.

So guys, I got my rMBP back yesterday. There are two possibilities which could cause the lag. The graphic card or SSD. My graphic card was changed by the tecnician and unfortunatelly there is still a lag. So he assumes that the SSD must have a defect because running the macbook with an extern HDD was very smooth he said. He couldn't try my SSD because I had forgotten to give him my password for login. So I will inform you after my SSD has changed.
