Windows On Mac :: 27" Display Issue Under Windows 7/256 Distinct Shades In Each Horizontal Bar
Jan 4, 2010
Under Windows 7, if I go to the following URL, I see a MAJOR problem:
[URL]
There is something like 256 distinct shades in each horizontal bar. NOTHING MORE.
If I simply drag my web browser over to my second monitor, a 28" 1920x1200 monitor hooked to the mini displayport, it displays PERFECT gradients.

I recently bought a used SR Macbook Pro and I have no horizontal scroll in any implementation of Windows. I've tried using Bootcamp, Virtual Box, and Vmware Fusion to install XP and/or Vista Business and none of my installs have horizontal scroll. I've used all sorts of drivers from 2 onwards, updated all my Windows installs and nada.
Is this normal behavior? IMO, with all the reviews of Bootcamp/virtualization, there have been no mentions of the lack of horizontal scroll which IMO is a big detriment to the implementation of Windows. Without horizontal scroll, Apple has effectively crippled Windows to be unusable...

I thought it might have been a graphics card problem, but these lines move with the apps even in expose mode.
Its driving me nuts. I had this problem before while on 10.4 Tiger and now again on 10.5 Leopard (fresh install on new hard drive).

I've tried re-installing and updating every possible graphics related driver for Windows 7 i cannot for love or toffee get the bloody thing to even recognize my display. I am using a 26" tv as an external display, it works on OS X (very easily), windows XP (also very easily) and even Vista (also easily) and connecting through a DVI/HDMI connector. Why not windows 7? I've scoured the web for answers but can't find anything. Is anyone at least in the same boat as me? I really need this solved soon

I have installed Windows 7 on a Bootcamp partition and use VM Fusion as well, I am trying to get my Windows 7 desktop onto my Plasma TV when I have only Windows 7 booted.
I have a mini displayport to DVI adapter (not worried about sound right now) but when boot into Windows I cannot find the TV as a output setting.
It used to be with my old PC I would see the TV as a possible output and I could chose either Dualscreens or simply set the Plasma as the main display.
Could someone please help me achieve this with my iMac? Am I missing a driver or just missing a setting?

I have a Macbook pro and was running windows through bootcamp. When opening windows the display is upside down and is staying that way. Have tried to reboot with no luck.

I've got a 2.4 GHz unibody MacBook running boot camp, and I'd like to have my new 24" LED Cinema Display set as the primary display so that, when I play games, the system recognizes that the resolution can, indeed, go higher than 1280x800.
However, when I right click and hit Properties to see desktop settings and stuff, right clicking on the Cinema Display shows that "Primary" is grayed out; it seems that I can not set it as the primary display.
Does anybody have a solution to this? I'd rather not use the nVIDIA settings to turn off the MB display and only use the LED display, as I'd like to be able to have AIM and a web browser open on the MB screen while I game on the LED display. I suppose if this is not possible under Dual View atm, I'll make do, but I figured I'd check first.

i've got a little problem with my Mac Book Pro.
I have a white line in the display where I also have my dock. So it's not always on the same Display. You can see a few pictures attached that show you that this line is some kind of weird. Windows that are always in the front like "About my Mac" are over this line and if I open all windows of one program I get three of those lines.
The lines are here since I updated my MacBook to the newest firmware.

when I woke my pbook up the screen had a horizontal line across it, and below that there is doubling and tripling of the screen image going on. Rebooting didn't accomplish anything and when I take a screenshot it doesn't show up there. I have a 12" Powerbook G4, running os 10.4.11.

I have a 2007 Mac Pro 1,1 with attached 24" apple display and utilizing 5 GB Ram and maxed out on internal hard drives. It's been a flawless workhorse and I mostly tax it with Photoshop which it does well. Well, yesterday, I was viewing a small video on my Mac when this issue occurred. Suddenly I saw these squiggly looking horizontal lines on my display. Then I saw a spinning beach ball. I had to shut down.
I double checked my display cables in case any were loose - no issues. Restarted without issue. Went back to work on my computer - no issues doing ordinary tasks such as opening windows, moving files and surfing the internet. Went back into Photoshop and resized several dozen images without issue. Then, this happened again... restarted. Zapped PRAM just in case. Fired up Tech Tool Deluxe (older version 3.1.3) and it found NO problems, I passed all tests.
Then... out of nowhere it crashed again, third time... I don't recall what I was doing to be honest. I shut down my Mac last night and this morning have spent an hour on and so far, so good. However, I'm not taxing it by doing anything intense. I need to use Photoshop for a project I'm working on so I will do that soon and see if this issue repeats.
I've tried searching the forums but can't find anything conclusive to my specific issue. What else should I do? What else should I check? Is this hardware or a software issue? I have temperature monitor installed - should I be looking at specific temperature increases and if so, where?
GPU going bad on logic board? This is a really close up image taken with my iphone, obviously the lines aren't this large.

I have an EMac G4 that has a number of problems, It is a 1.25gz. Sometimes it will boot to a blue, blank screen, on holding down the alt key I see the boot drive and I can start up (10.4os) but will go to the blue screen again. When it does start up properly, which it does for no apparent reason, there are little dash shaped spots on the screen and a flashing horizontal flicker. I ran fsck and disk utility and installed a fresh version of 10.4 to no avail. I do not have the original disks so cannot run hardware test. The computer falls under the Apple emac screen repair but they will not accept it because it is out of the three year time limit, very frustrating and unfair.

My iMac boots up (OSX 10.4) and when the desktop is about to appear the little spinning wheel start to get "fuzzy" (yes only the wheel), then when it's time for the desktop to appear the entire screen goes blue with horizontal lines across it. I can see nothing on the screen at all except that mess.
Weird thing is, if I boot using the install disc, everything is fine. he display never screws up. So I am guessing some file or something is corrupted in OSX?
I was going to do a restore, but since there have been some updates since I got it, I am worried about that whole process and not being able to get to my pictures and what not on the HD. The procedure where I can archive the current OS and reinstall the original seems like my next step.

i recently bought a 13"retina display macbook pro. It is so disappointing. There is a horizontal line that appears on the screen and disappears. This was for the third time i had to face the same issue. When i explain to the staff at the apple store they say that they have not come across such issue, for which i showed a proof from the other part of the world.

I have a 2.8GHz Intel Core 2 Duo 24 inch iMac in may-june 2008. I bought it because I wanted to avoid the 20 inch display problems. Somehow I feel I ended up with the wrong side of the deal. Check the snapshot please:
The picture was taken using my iPhone so it's not exacty Cannon quality, but still, it describes my problem in 1000 words
What would you do in my place. Would you risk getting another one, maybe a crappier one? It is ludicrous that you take part in a russian lottery when buying a fairly expensive product like a Mac.

I'm running 8GB RAM as I have been for several months now. I typically run several apps at a time for days at a time rarely dipping below 1GB available. When I do I use the Free Memory app to free up RAM.
Minutes ago I left my MBP for a couple minutes to do something across the room. It began making single short beeps spaced a couple seconds apart. When I ran over to check out what was going on I noticed the display had 2-3 vertical stripes through it each containing dozens of horizontal colored bars. The beeps continued without stopping. The display was unusable for the duration. I could not tell if th keyboard or trackpad were responding so I chose ot reboot.
After reboot it seemed fine and reopened all of the apps that had been running previously. Or is this a sign of specific hardware beginning to fail?

my MacBook pro display that there are frequently horizontal grey lines going across my screen. I've noticed it mostly when the display color should be grey or white, but that's not always the case. It occurs mostly in my Google search bar using Firefox, and also occurs heavily on Facebook in the comments/reply section of a post. Outside of the browser I've also seen it when looking through some personal photos, especially of the sky, the lines will seem to sort of outline different contrasts in white or light tones, kind of like the Magic Wand tool would do in Photoshop. The lines do flicker and change when scrolling.I attempted to snap a photo with my iPhone the best I could.
My specs:
-13" Macbook Pro (2009)
-Intel Core 2 Duo 2.26 GHz
-NVIDIA GeForce 9400M
-Resolution: 1280x800, 32-bit Color

Is it better for me to buy the upgrade for windows 7, from vista to windows 7 or to buy the full copy? If i buy the fully version, should i get rid of my pardon, and re-do it with bootcamp, or should i just do it over my current pardon? (Vista) I just want the best way, less pain, less anger. Im willing to pay more for full IF IT IS THE BEST way to do it.

So I had a recently purchased 17" BTO with the 7200RPM drive that worked great, but with one issue - the display would have horizontal scan lines and black out occasionally. So I called up Apple and eventually managed to get a cross-ship set up(they let me hold on to my current unit, charge my credit card and send me a second brand new 17" unit as a replacement,and then refund me for the second 17" after I send back the defective unit).
Anyway, the replacement unit looks great, but with one issue - there's a very small light dent on the bottom panel(maybe about the size of a dime). I was annoyed but don't think this is worth having to exchange, since I could probably just unscrew the panel and pop it back into place.
However, what really got to me was the fact that my replacement unit was slightly louder than my original - my original is so silent that I can't even tell it's on. However, with my replacement unit, I can hear the hard drive spinning, which is slightly annoying.
Anyway, I proceeded to restore from a time machine backup and test my replacement unit when I noticed that it would occasionally get the hard drive click + beep + freeze issue that many others who have the 7200 RPM drive seem to be facing. It's extremely annoying, and more importantly I miss the complete silence of my older unit.
My question is, while I'm still in possession of both units(which both have the exact same specs, same 7200 RPM drive, etc.), should I simply just open both up and take the silent(good) hard drive from my old unit and put it into my new one?
The click+beep freeze issue is really pissing me off, and my old unit didn't suffer from it - it's just this replacement one(doesn't make any sense).Anyway, would notice if I switched the hard drive? Would I get screwed somehow? Do they keep track of the hard drive serials or something?
I really don't want to go through the pain of sending this back, especially considering that a LOT of people are suffering from this issue, and I don't want to end up with another defective drive. I'm sick and tired of games and just want a computer that WORKS.

So i gave a friend of mine a hand with his 2009 27" i7 iMac by installing Windows 7 for him. Unfortunatly for some reason after you get through all the meat of the install and it restarts to finish off and ask for personal information but here's the problem. The display is showing nothing! You can hear the fans are on and booting into mac is fine but I can't get any farther with the Windows 7 installation because i can't see anything! I know the disc works because I installed from it the night before.

Under 10.6.8, it has been my habit (and pleasure) to open very wide terminal windows across as many as three displays in order to see the results of somewhat wide database queries without text wrapping, which affects readability and cuts the number of lines visible on the display window at once.
Under 10.9.3, when I adjust a window over towards another display so that the window would be on both displays, the window is "ghosted" until I let go of the drag bar, and if the move has not fully adjusted the window to land entirely on the display it is moving into, that half of the window promptly disappears.
Am I missing something about window positioning under Mavericks? Or, is there any way to regain the previous, multi-display-friendly window handling in Mavericks?

I installed bootbcamp today and windows 7 and after a period of time the following message would pop up after the screen froze and various artifacts would appear or the screen would be divided in half horizontally with artifacts in the middle.
"Display driver stopped responding and has successfully recovered"
I don't think this is a bootcamp driver issue. This is an issue between ATI and Microsoft and has been going on at least since 2007. Not much to say about it at this point, but I was wondering if anyone else has experienced this issue with the new iMac's and windows?

Has any one had any problems using an external display (Apple 24 inch LED is what I am using) with Bootcamp with an Apple laptop (recent MBP) in the closed lid position. I start Bootcamp & Windows, close the lid, but the display/computer won't restart once I plug in the peripherals.

I'm trying to install Windows 7 on my 27" i5 and I've been having a little trouble. I heard about people having issues with screens going blank, so I went ahead and followed Apple's instructions on the matter. I put the files they said on an SD card and started into the Windows installer. But after about two screens, it says, "Windows could not display the images available for installation." Then my computer restarts.
