MacBook Pro :: Displays A Diagonally Patterned Screen?
Jul 6, 2012
My MacBook Pro will begin to boot when the screen suddenly becomes distorted by an alternately patterned gray screen. I have performed 2 safeboots and after them, it seems to work fine for just a few (3,4) boots after that. One time when it booted successfully, the screen's background light began to flash very quickly until the screen was distorted again like in the beginning.
I've tried cleaning the PRAM and the NVRAM also but it did not fix the problem.

I have a macbook pro with retina display, and i want to connect a monitor to the mac. When i connected the mac to the screen, the screen is on another desktop (called desktop 2) but in misson control (on the mac) there is no "desktop 2" and when i add a desktop on the mac, the screen becomes desktop 3. How can i control both displays (screen and mac) but with different windows open on different displays on the same misson control?
So basically i want to have a certain window open (eg. preview) on the screen, and at the same time run (eg. google chrome) on my mac without mirroring the 2 displays.

I have a 13" Macbook. I had a 250 gb and a 500 gb internal hd's already crashed. I just bought a brand new 250 gb thought that this will work. I was wrong. I inserted this hd and turned on the on-switch. The same screen I saw earlier showed again-a blue screen with a file with a (?) sign on it.

My MacBook Pro3,1 (early 2007) produces a screen of narrow horizontal bands of black and white, with a few scraps of pale blue and a few fragments of letters, but ONLY when booting from the original install DVD. The displayed pattern has a narrow vertical line in mid-screen, with one side of the displayed pattern shifted up (or down) by the width of the horizontal bands. This display is unreadable, and therefore unusable.
Apple serviced the MBP's defective NVIDIA GeForce 8600M GT graphics processor in 12/2010. A year earlier they replaced the SuperDrive.
In May 2011 I replaced the Apple Memory with 4 GB of Kingston memory.
The MBP boots off of the hard drive into SL 10.6.8 with no problems.
In preparation for an upgrade to Lion, I booted off of the original Install DVD into the Apple Hardware Test, and ran one pass of the extended test. It took about two hours. No problems were found. Next, to use Disk Utility to check/repair the hard drive structure before the upgrade, I restarted while pressing the C key to boot from the Install DVD. The DVD was accessed, the grey Apple screen displayed, but at the end of the boot process the striped display appeared instead of the expected system installer display.
This Install DVD boot failure is repeatable.
I have rebooted with no problem from the hard drive.
I have rebooted off of this Install DVD, but into the Apple Hardware Test (D-key pressed), and rerun the short test.
I have reset PRAM and SMC, but the problem remains.
It is possible that the Install DVD was not used since the 12/2010 graphics processor repair, until now. Although I do not intend ever to use the Install DVD to roll back to MacOS 10.4.9, this is the tool I'm supposed to use to repair my system hard drive.
I'm baffled because this problem only appears when booting into the installer program. Is it possible that the repair of the graphics processor (or even the SuperDrive replacement) introduced an incompatibility between my MBP's hardware configuration and that expected by the Install DVD

How do I re-center an application that displays itself too far to the left on my screen? Both my contacts and Safari are showing up too far left -- so that I can't exit/minimize/maximize because those little buttons are off my screen.

It either interprets "diagonal" scrolling as horizontal or vertical, or left and right. There is no horizontal and vertical at the same time. I don't recall my previous MM being able to scroll diagonally, either.
I'm not sure what Apple means by "360 degree scolling."

I recently had my screen replaced because of a crack. Now I find when I open the laptop to use, after being on sleep mode. It momentarily turns blue, sort of flashes/glitches then works normally. Should I be concerned?

I sold my Powermac and have purchased an Mac Mini, but in the meanwhile I have been on an old pc I had laying around. I realized this week that the ubuntu machine's screen saver was set to 'black screen,' and the power management panel was set to set the displays to sleep after six hours! This has been going for the past few weeks as I waited for a new machine, and now that the mac mini comes tomorrow, I am worried I have caused undue stress on my two dell monitors.
Is this something in my head, or is the prolonged display of pure black a problem for LCD monitors?

I have a Samsung 204B 4:3 21" screen and a 20" Cinema Display from 2004. I want to use the samsung because I prefer 4:3 ratios, but OS X looks seriously on it. I know its something with OS X, because Windows appears nice and crisp.

I have the new macbook unibody, and use it from time to time to dsiplay things to an external montior, plasma, projector, etc. Using a mini-display adapter to a converter to get s-video was a challenge, but I figured it out. I have used this many times, as I am a DJ and need s-video out to connect to most devices.I was at an event saturday night, and the display on the external device (projector) kept displaying my desktop, NOT the external feed.
It was NOT set up for mirroring, as it seems like the displays were 'switched'. I had my desktop on the projector, and my external on my macbook pro monitor. I tried to fool around with arrangement and resolution, but to no avail. I understand that sometimes you have to drag your source to the right (of left) to get it to display on the external, and this was done, but it was still reversed.I know it was something simple to get the 2 switched back to the way it should be, but I could not figure it out. Any advice? None of my apple buds can figure this out.

when I tried to launch the macosx lion, after display the login window, the whole window become black.
Then I inject the U-Disk that has MacOSX Lion Installer in it, after the white screen, it become black too. So I can not re-install macosx.
Then I tried press `shift` at login. It also didn't solve the problem. At last I tried the single user mode. It appears some problems:
... USBF ... The IOUSBFamily is having trouble enumerating a USB device that has been plugged in. It will keep retrying. (Port 4 of Hub at 0X24000000)

Been working with a new mac mini in my office the last 2 days. The power settings are set to make the display only go to sleep after 15 minutes. System set to never go to sleep and hard drive never spins down. 3 of the 4 times since working with this thing when moving the mouse to wake up the display I get nothing but noise and snow on the screen. To get back to functioning correctly I have to put the computer to sleep with the power button and back on again. Once it comes back, it will work fine.
New mini 2.4 running 10.6.4. Monitor is hooked up via DVI through the mini display port.

I have a mid-2010 Macbook Pro with the Nvidia 330m. Does using Mirror Displays require any less system resources (such as VRAM) than Dual Displays? I mean it shouldn't right (assuming that you use the same resolution for Mirror and Dual) because there is still content on both screens being written to the VRAM?

I would like to set up a 24" monitor and 30" monitor with my 15" MacBook Pro (v4.1).
The graphics card is the GeForce 8600M GT 512MB.
It's important that one of them be color calibrated using my Eye One Display 2.
Is there an external peripheral that can make this work?
If it's not possible because my computer is too old - does buying one of the more recent MacBook Pro's make this possible?

I'm trying to get my macbook hooked up to two external displays.I remember seeing a post about it previously, with a solution, however, I stupidly did not bookmark it. Does anyone have a solution? As you know, the Macbook only has 1 mini-dvi port.

so I love Macs but they're frustrating the hell out of me. I wanted to run dual 20" displays (portrait) and one 30" displays using a Mac Mini and a Macbook Pro. I know the new Mini should do it, but I've heard bad things about Apple's Dual Link DVI adapter. Also, I don't think there's a way for a Macbook Pro to drive a 30" Display and a 20." Am I missing something? What should I do?I'd much rather buy a Mac Mini than the Mac Pro which is way too powerful.

So here's the question. Running Lion on MacBookPro (17" with thunderbolt port) and need to connect BOTH a Mac 27" miniport display and a Mac 27" thunderbolt display. The miniport display needs to be last in the daisy chain, but not be connected to the thunderbolt display according to Apple (and they're correct - it goes black). Two possible solutions - (1) thunderbolt hub and connect both displays to that or (2) put another thunderbolt accessory in between the two displays.

I'd like to add a larger (21" - 24") external monitor to my late model 15" MBPro, but don't want to spend $999 on the Apple Thunderbolt display. What should I look for in an after market external monitor? How would I connect it to my MBPro ports?

I recently purchased Thunderbold (TB) display and 17" Macbook Pro. My TB flickers quite often and disconnects. Then I have to power off TB and reconnect. All updates are current. Dont know what the issue will be. Is there any utility to check the condition of TB. I did not connect any peripherals to TB except the Macbnook Pro.

I purchased the Toshiba Dynadock U3 - which ran well with Win 7- hoping there would be drivers for the Mac OS. Anyone have any ideas how I can accomplish this configuration? If not, then what is the next best configuration where I do not have to keep connecting and disconnecting wires fron my MBA. Just want to connect one wire (e.g. - USB cable) that that's it. Is this wishful thinking?

I would like to run two displays, an older 20" Cinema Display with DVI and a 27" Apple Display with mini-Display port to the new 15" Macbook Pro Retina. I realize that the mini-Display can go to one of the Thunderbolt ports so what what do I need for the DVI display?

I keep seeing articles since yesterday stating that the new MBP retina display supports 3 external monitors and the new Macbook Air supports two (through just one ThB port?) but how come no one says anything about the new regular MBP's support? If the Air supports two isn't the regular MBP also supposed to be able to work with two external monitors?

My mac will not automatically detect displays, and even sometimes requires a restart. I've reset SMC, PRAM, repaired permissions, and cleared the caches.
