Intel Mac :: Why Does Display Have Two Diagonal White Shadows When Switched Off
Apr 4, 2012
my display appears to have two diagonal white streaks on the dark screen when it is off - I'm finding this really disturbing as this machine is still well under a year old and I can find no reason for this. it doesn't show up when the screen is on or I'm working on it.
Info:
iMac (21.5-inch Mid 2011), Mac OS X (10.7.3)
I want to white out a couple of lines on a PDF form. White out. No box lines, no shadows. White. As in those lines disappear. What is the deal with the shadows? Is there a way to just have parts of a doc whited out?
Info: iMac (21.5-inch Late 2009), Mac OS X (10.6.8)
I see since several months some shadows and spots on the top left corner of the screen. I've read in many threads that this is a known issue (defect I would say, since I never misused my iMac).Â
My question is:
is this defect recognized by Apple and do they fix it for free?
I have a refurbished iMac. Everything was perfect after I noticed that if I don't move any given window, it will leave a shadow on the screen like this: [URL] ....
Just switched to Lion and the size of the dock items are too samall I have increased their size in pref but they are still very small. Also I am missing several dock items from the right side of the dividing line and yet if i mouse over the empty space the captions of the missing icons show and some times I can select the desired action by clicking on the empty space where they previously showed.
Info: iMac, Mac OS X (10.6), with lion can I open power pc
I just received my new 17" Dell LCD (1704 FPV) yesterday and hooked it up to my windows laptop (my new Mac Mini will be here in a couple of days). After a couple of minutes of looking at it, I noticed very thin lines running diagonally and parallel over the whole screen. The lines go from top left to bottom right and appear to be moving (yesterday I thought they were moving down, today the appear to be moving up). Those lines I see are really very thin and hardly noticeable, but now I've seen them once, I see them all the time. It shows especially on a plain background, which appears to be very lightly striped. Unfortunately, it's nothing a screenshot would reveal, I think. Does anyone know what those lines are, whether they're normal and what I could do about them?
I have no idea what's causing it. I had a feeling it was VLC, but the lines show up when it's closed. The lines aren't fixed, they move with the window. It's like the window shadowing thingy is broken. I've done the obvious, repair permissions, reboot.
I actually don't know how long I've had this problem, as I just sort of noticed it one day (it's not all that readily apparent). The title of this thread basically says it all. There's a "fuzzy," thin white(ish)/translucent band that stretches horizontally across my 15'' glossy MacBook Pro display (purchased in early 2010, so I guess it's considered a mid 2009 model), about an inch up from the bottom of the bezel. It's only super noticeable on top of relatively neutral colors. I'm quite certain that it's a hardware issue, as it doesn't appear in screenshots. I've attached a photograph to this thread so you can see it for yourself.. the band I'm talking about is just above the mouse pointer (and clearly my dock is hidden so you can see it easier). If there are any hardware savvy people here, I'd be most appreciative if you could clue me in to the exact nature of the problem, and whether or not you think I could fix it myself... I think my basic 1 year warranty is still good, but I haven't decided if the problem is worth living without my mac for a few days (or weeks? this is my first apple computer, so I don't know how long repairs typically take).
I'm trying to set up a MacBook (White) and 30" Cinema Display - I'm using an Apple mini DVI to DVI adaptor. The max resolution I can set the macbook to run at is 1280 X 800 and the Cinema display looks all blocky and not good - I know the macbook is not capable of running the 30" displays native resolution of 2560 X 1600 but I thought DVI could go up to 1600 X 1200? I installed the 30" cinema display software / drivers - Is there anything else I can do in Tiger to increase the maximum external display resolution?
just bought a 09 white macbook to upgrade from ibook 1.42ghz i use an iiyama 22" external display to use sibelius. this screen was working well with the older ibook, picture was fine(used screen span doctor driver). but when connecting monitor to new white macbook the display has a slight shimmer and shakey, its v difficult to read notation on this. for the iiyama screen the best resolution is 1680 x1050. when macbook is in sleep mode this resolution ( 1680 x1050 ) is automatically on the iiyama screen, but the quality is inferior to the older ibook. setting monitor at 1280 x960 stops shake but distorts the picture. anyone know why im having this issue on a brand new macbook? is it to do with having to use a DVI to VGA connecter on the new macbook?
Display screen is white and there are no icons, just pointer. Tried to restart. Could the hardware be the issue. Only 6 months old and already had hardware restored once.
When I try to open the itunes store on my mac, all it does is display a blank white page. My apple ID is displayed correctly, but I can't access any new material on the itunes store.
I bought my first MacBook Pro in April 2008. In 2010 I had a problem with MBP/Display, the logicboard problem which occurs with many MBP. As this was resloved with test and replacement of logicboard, it was good until last night
But since yesterday I've had to experience the Vertical Stripping, shadows at bottom of screen. I restarted the machine, I shut it down and this problem hasn't disappeared.
I did research online, checking the System profiler--->Graphics Displays--->PCIe Lane Width:Â Â Â Â Â Â Â Â Â x16--->GeForce 8600M GT
Nothing appears to be out of sorts, also I did a hardware test from start up and no hardware problems were found.Â
So what now? I'm using the MBP now as I type, I still have use of the machine but the vertical striping is not going away.Â
can anyone tell me why my screen on my imac is all white? the last time i use it was 6 months ago because i had to move. so i unplugged it and now i wanna use it again but when i turn it on, it's all just white on screen, i try to reinstall everything by using the disk but still nothing, can anyone tell me what's wrong with my computer?
Recently, the display of my MacBook Pro (unfortunately, out of warranty) often is black/greyish after wake-up/start-up with a thin white stripe in the middle of the screen, and the computer (obviously) cannot be used in this mode (you can hear it start up, but since the screen is completely dark, I can't actually do anything - restarting doesn't help either).
At first I thought it might be the graphic card (since there is a known problem with NVIDIA), but I've brought it in for repair where they have run multiple software-tests, and no error code was returned (when I brought it in it magically "fixed itself" and, once running, the problem can't be re-recreated), so nothing was fixed.
It seems to me that the MacBook for some reason cannot find or communicate with the display because I just discovered that if I hook up an external monitor, it manages to find that, and, after disconnecting the external monitor again, also "reconnects" to its own display. It then generally runs fine until I physically move it (ie. put it in my backpack and carry it somewhere) - after being moved, it tends to have the same problem again (not always, but more and more often).
Have you had any similar experience and/or what might cause this and how it could be fixed? I'd like to avoid replacing the display or something of the sort until I know for sure what's going on.
My Macbook Pro display all of a sudden went to the 'white screen of death' as I've heard others refer to it as. I've tried zapping PRAM, resetting SMC etc. to no avail. When I connect an external monitor, I am able to use the Macbook without problem, so I know it is video card/controller/display related issue. I'm going to send the Mac in for repairs. But before doing so, I'd like to erase my hard drive so I'm not sending them all of my data with the computer. I've done a time machine backup, so all is fine there as well.Â
My problem, is that in order to erase the hard drive, I need to boot from the OSX install disk. No matter what I try, I can't do this with my external display. If I insert the disk, and hold down the C, my Mac never recognizes the external display plugged in and so I cannot see to get to the disk utility tools on my OSX install disk. I've tried using Command-display dim button, to no avail.Â
I've tried simulating a clamshell mode boot where I close the lid as soon as the boot starts (with the OSX install disk in the drive) and I get a kernel panic every time. Even if I didn't, I don't see how I can close the lid at startup and hold down the C key at the same time. Â
