Mac Pro :: Square Pixels Green, Red Or Blue With ATI 5770?
Apr 15, 2012
To see how it looks: [url] I can not find the cause of its pixels that appear on the screen. Only in the viewer. They occur randomly when I add an effect FCPX. (not just a plug-tier) These pixels are found embedded in the video if I made one!It does not appear immediately launching FCP but after 5 minutes after playing withthe settings of my corrections.When they appear in FCP if I run photoshop, I have the same pixels in the window of my image in Photoshop I did not think I shall give my card GT120 But I have an ATI 5770 with an Apple MacPro 4.1 What I tried: reinstall FCP New partition with 10.6.8 and 10.7 fired FCP preferences Reset PRAM + SMC Changed the cables and adapters of my screens Does this card is defective? Why do they not appear in the screen

Been on a Mac in one form or another but never saw this. It's not even mentioned on the apple.com site under startup problems. Started up on my eMac and got this blinking blue dot that looked a bit like earth in a gray square. Whole think was about an 1" square in the middle of the screen. The startup tone was normal.

I have a Mac Pro 1,1. Tonight the display starting looking like the screen shot attached. Then it wouldn't come up at all. Black screen, with a few bands of green pixels.
My first thought is that the Graphics Card is going bad. Odd thing is, though, that I captured this via screen capture from another Mac. Could it still be a bad GPU if it looks this way remotely? I'm not sure how these early Mac Pros work. I have Mac minis that, when the display is off (or headless), the GPU is not used to render the GUI via screen sharing. So, I tried disconnecting the display from the Mac Pro, and I get the same screen shot.
I can boot the Mac Pro into Safe Mode, but that is it.

Sometimes the LCD display goes into this mode where in some areas you see red and green pixels flashing. I have taken a few pictures, which obviously don't render the flashing effect, but give you an idea of what it looks like:

This is a MacBook Pro pre-unibody The graphic card is an ATI Radeon X1600 I ran the TechTool Deluxe tool to test the video RAM (and everything else), but it didn't detect anything wrong I have never seen this when the laptop is connected to an external monitor This doesn't happen that often; say 1 times out of 10, usually after the laptop comes out from sleep. The issue stays for a few minutes and then goes away until next time, so I am unlikely to have the problem when I go to Apple Store for service.

So I have this collection of pixels near the bottom of my screen but they're only visible over a dark grey area, like when you're in the login screen (I have an early 2013 MBPr 15 btw)
It's probably a problem with the screen itself and not the GPU (or maybe the connection between them?) since if I take a screenshot it's not visible and I've connected it to an external monitor and it doesn't have it.
I took a picture of said problem [URL] .....
I've had this for a few weeks now and I've tried those youtube videos (I just to have some image retention after leaving something to run for a long time) which have decreased the amount of pixels. They all dissapeared for a few hours and now they're back.

I have a late 2008 version of the 17" MacBook Pro. I've been using it today and it's been completely fine. that was up until I was uploading my recent holiday photos to iPhoto. I left it to upload and came to check on it after 5 minutes. I found the program had frozen and pink and green pixels were spotted all over the screen.
I turned the laptop off by the power button. When I started her up again I found the white screen with the pink and green pixels everywhere and apple logo appear. It starting booting and then just stopped. the screen froze and nothing was working. I've tried booting up in safe mode and again it just freezes. I've included a photo I've taken if the frozen screen.

I have an early 2008 version of the 17" MacBook Pro. During the process of uploading photos to iPhoto, the screen froze and pink and green pixels appeared. I shut down by the off button and upon on turning it back on found the screen as shown below. The apple appears and then the clock spins for a moment then freezes. I cannot get any further.
I've tried booting in Safe Mode and other options I've read when trying to boot but to no avail.
Someone said I need to run the AHT but as this was purchased from a friend, I don't have the installation CD's. I've found a DMG file of the AHT but am completely at a loss as to what to do with this.

I have had my MacBook for just over a year. A weeks ago, the display started go weird: - strange shapes started appearing on the desktop - a fluorescent green (like vertical strips of 5 or 6 pixels in a group), sometimes as a shadow of a previous open window, sometimes just random squares or lines. The blocks of green go if i run my mouse over them with the button pressed down. -a fluorescent green light sometimes shines around the programme tiles in the dock. -shadows behind open windows very accentuated and fluorescent green - sometimes text on web pages and documents look garbled - again this goes if i run my mouse over them, and either go or comes back in a different place. Some times i can go a few hours without experiences these problems, other times the issue is there on start up. I ran the quick hardware check, and no problems were reported, a week later i ran the extensive check, and again the system seemed fine.

My tibook .867Ghz was working fine this morning, but now when I restarted it this afternoon, the colors are all off (lots of green and rapidly vibrating pixels in background). The computer works, I can run programs and so forth. There are no changes to the displays settings, still 1280x854 and colors "millions". When I switch to thousand or 256 colors there is no significant change.

This may have been posted earlier, so sorry is this is a repeat. I've had this PowerBook since the first 17" versions came out in early 2003 and it has worked wonderfully. It even came adrift on a bicycle one day (strap broke with a brand new sleeve bag) it skidded down the road and bashed into the curb... still kept working.... other than a couple of dents and a lid that never closed again quite so well, it has been a fab machine.
Anyway, a few months ago the screen started occasionally going a green/blue tinge, almost like very fine stripes down the screen. A wriggle of the screen seemed to fix it, but it has now become quite bad, and stays like that for most of the time. I figure it must be the connection to the screen from the system, as when using the laptop for presentations (connected to a projector) all is good.
So my question is, does anyone know a easy fix? I heard that the wiring is built in, and needs the screen replacing, which doesn't make sense given it's nearly 5 years old.

for the last week or so my MBA has been showing a ~3 inch bar running vertically along the middle-left of the display. Until today, the area looked just like blurry pixels (some things like graphics would still appear, so I don't believe the problem is with the pixels themselves). Now the area has become a gray bar of pixels.

So after waiting 4 weeks my High-res Glossy MBP FINALLY arrived...I was so happy. Got home switched it on and WOW it really is a beautiful machine...After using it for about 30 mins however i noticed a small dot to the lower right half of the screen... I looked closer and realized it was either a dead or stuck pixel( I dont exactly know the difference). I did a few test on it, and its ONLY visible when a light color is on the screen (White, Gray etc) However when the screen is DARK blue, Dark green or black it cant be seen at all...
It kind of looks like a TINY speck of water or liquid the size of 1 pixel stuck under the glass... I noticed that it does get lighter and darker when i adjust the brightness of the screen. Can anybody give me some tips? Anything i can do to fix it? Is it in fact a dead or a stuck pixel? I tried the JSscreen fix which is basically a online tool that opens up a flashing screen...Ive had it on for about 30 mins...but no luck

Since upgrading to 10.7.3, the top right and left corners of my finder windows (as well as many other apps) are square. The bottoms remain rounded. I have even reinstalled 10.7.3 using the combo installer, to no avail.

I can't work out how to search for images where the image's width is equal to the height. This is regardless of the actual number of pixels.

I used to use Command-shift-4 or Preview/Grab/Selection to capture screenshots, which worked great - capturing as png and saving to the desktop. However, now I just get a black coloured square captured with both methods. Capturing a window is fine, this just happens when it is a selection.

I have a small white square that appears on my screen, it's not just on my background it's on whatever I open. What is causing this and how do I get rid of it? I have a brand new laptop, less than two months old.

A bizarre thing: when I wake my Cube from sleep, the mouse pointer seems to have converted itself into a black 1" square. As soon as I click in a program it changes back to an arrow.

My two previous older macs have been perfect to me, but this new MBP I5 model is giving so many issues lately. Every once in a while, my computer's graphics (I am assuming) goes crazy, and I get this pixelated distortion that's right in the middle of my screen that's about 2"x5" on my 17" screen. This happened just earlier, while I was using Safari. However, even after closing all of the Safari windows down, the distortion will still be there, and will stay there regardless of what I have or don't have open. Logging in and out will fixes the problem, and everything goes back to normal for the mean time. Any one ever experience similar problems or know what I could do to see what's going or fix it?

I am considering the move from the GTX 285 to the ATI 5770. The reasoning behind this is that I'm wanting to change from a Dell 30" to the new 27" Cinema display. And obviously the 285 won't connect to this monitor. My biggest concern is the potential drop in performance. Having said that the Most intensive graphics application I have is Call of Duty 4: MW. This is at the moment at least. If better game come out that are more graphics hungry things may change, but I can still upgrade down the track. I'm really struggling to find any comparison between these two cards.

Seen this discussion scattered throughout threads but I wanted to ask it directly here. What uses could really take advantage of the 5870? I've seen gaming benchmarks (5870 blows the 5770 away) but not much else. Specifically, I'm primarily using Aperture and some light gaming. But I'd love to hear why many of you are opting for the 5870.
