Hardware :: IMac G3, CRT Monitor Doesn't Show Dark Colors Well - Dark Clors Appear Black
Jan 1, 2010
I can barely see digital pictures and the likes. But websites and such i can see fine so long as the colors are light and looking on this site... [URL]
the first image i absolutely cannot see, it is 100% pitch black.. the other bellow it shows up just fine. But the two left/lowest squares on the color table on the very bottom the page both appear the same shade of pitch black.
I can see light but not dark. I tried callibrating and adjusting brightness and contrast.

as you can see in the images attached below my MBP is having some video problems. The laptop was purchased about a week ago brand new, and it just started having these issues.

So I've got my MBP that I've had for about 4 months, the thing is. It just recently started to have screen flickering issues. I'll be sitting doing w/e as usual and all of a sudden the display goes dark, almost black, for a second, then comes back up again. I have yet to find any trend in when this is happening, but it is definitely happening on battery as well as plugged in, but it seems to be getting worse.any one have any idea what this could be, something I can fix on my own, or should I take it in?

I have a late 2006 Macbook, and my dad has an early 2009 Macbook. I was comparing the two today and noticed that there was a significant difference between their LCDs. My dad's Macbook has a lighter, more normal display. While mine has a yellow tint to it and is darker. Both computers were on the same display profiles and both had the same brightness set.
Is this just how LCDs are as they age? Or is mine really not supposed to have that yellow tint? The new Macbook is on the right in the pic.

The printer prints copies in a very light grey colour. I would like it to give a normal black print. It is the driver. If so where do I get an update for the driver. Or what else can it be.

My iMac has these dark spots on the screen and I wanted to confirm that it is a hardware issue before I make an appointment with an Apple genius. I thought it was dirt, but cleaning it didn't do anything.

I have a late 2007 20" Alu iMac and when ever I watch videos they appear too dark. I have tried changing all the settings I can find and nothing helps.
Its ok if I use VLC as I can change the brightness within the program but anything else ie quicktime, youtube or other embeded video always looks way too dark.
Has anyone else encountered this or is there something out there that I can do do brighten the video image?

So after giving up the new iMacs after two replacements about six months ago for yellow screens......I thought I would try again.
The good news is that the white is very uniform with no yellowing. The bad news is that it has this dark band across the bottom of the screen just above the dock.
So I am basically in the same spot I was six months ago. Replace the unit for a new one, replace the screen, or just live with it. Maybe I am being too anal but for $2,500, I shouldn't have to live with anything but a perfect screen.

My screen has gone to a very dark grey on startup. I can faintly make out the desktop icons, but it is about 98% black. Everything else seems to be fuctioning. iMac G417" Flat Panel 17" [Pixar-lamp style] OS 10.4

I replaced my iMac G4/800 17" hard drive that was failing (S.M.A.R.T. status) tonight. Textbook operation, following directions from xlr8yourmac.com. No problems at all. I pre-built the drive with Tiger 4.10 in an external case (using the iMac as host) and transferred everything to the drive and tested. I booted off the external drive for a few days for testing. Again, no problems.
I got the iMac back together and booted up. Everything sounds fine but the monitor is black. It's as if there's no power to it or perhaps the lamps were just out.
When I press the power key for 1-2 seconds, the mac goes to sleep and the white Sleep Light on the front of the monitor comes on, so the monitor would appear to be getting power.
The Mac is working, evidently, as the chime for new mail sounded and the new drive chirps a little (very quiet though, btw).
I do NOT have a second monitor to hook to the VGA port, unfortunately.
On one reboot there was a sine-wave 'bong' sound, but the Mac proceeded to boot. I shut down again after that, took the housing apart and checked for trouble. Nothing. The video cable and connector is fine. There are no cables pinched or cut that I can see. And I did ever-so-carefully align the two halves when reassembling.
On the third boot I got the normal Mac chime (no bong/gong) and it booted fine - with no video.
One side note that I expect to be un-related: I left the HD jumper in cable-select mode, as the drive that was in there was also set on cable select (was a Western Digital 250GB drive; the new drive is a Maxtor).
What's wrong with this iMac monitor?

I would like to add another color for the events in my calendar, but when I click on the drop box, it only shows me home and work with no "other" option, like I've seen other people talking about. How do I add a color?

I have a question (whoa). I have an iMac Dual Core, bought in mid-2007 (it's the White Plastic version, not the newer Aluminium with the glass-display).
For some time now I had some dark spots, kind of shadow like in the bottom left corner. I wasn't bothered too much by them, but they got bigger, and now I have these in all of the corners except the bottom right one.
Anyone got any ideas how to get rid of them? (no, no three-year guarantee plan ... stupid me), or if not if it'd mean to replace the whole display or if it's just some cleaning (I talk money-wise here ...)
I attach two not-so-good pictures (the background is plain-white and the image is a bit enhanced ...) so you guys can see what I mean.

Allright, I have a 24" iMac. 3.06 Core Duo 2 4GB RAM etc etc.
Just now, as I was innocently talking to a friend using iChat, the top of my screen flickered once or twice and then went dark. I am typing on it now, so it is not unreadable, it just looks like the back lighting has gone off on the top half. The middle is relatively light (bleedover from bottom back light?). I have tried playing with the hinge to no avail. After I reset the computer, cleared pram-nothing. Zippo. I got the top to stay lit for about a half second after reset, but it then flicked off again. Do I need to load up my iMac and drag my ass to the Apple Store (it really is quite a task to drive there)?Here is a horrible cell phone picture (and no, the screen IS dark, that's not a shadow.):

I purchased a new late 2013 27 inch iMac 3.4Ghz i5. The only thing I did after pulling it out of the box was restore Time Machine from my previous iMac. On startup the machine boots as expected, but gets interrupted by the screen turning a dark blue, and the apple logo turning bright red, for about a second or so, then boots as normal, and opens Mavericks. I've spoken to Applecare - they suggested I re-install Mavericks, which I did. The problem is still there. I've done a hardware diagnostics test - no problems. Though I wonder if it could be a faulty graphics card? As far as I'm aware there are no other issues with the iMac. The machine is under warranty but would love to solve this if possible.

Since to switching to an iMac from a PC, I have noticed that all of my images while looking great on my monitor print out way too dark. I had to actually record an action in Photoshop to adjust the images prior to printing. I could not understand why and just figured well it is what it is and not much I can do about it. However, on reading the June issue of Shutterbug magazine, there was an article in there in which they specifically mentioned the iMac,and the problem that was being experienced by everyone, professionals and amateurs alike with the "dark" prints, and put it down to the fact the iMac monitor was too bright ergo the issue with the dark prints.
Has anyone found a way around this rather than having to adjust the image way out of range in order to get it to print correctly and then revert to a prior state? Please.
PS - I am using an EPSON R220 and an EPSON 1400, both of which printed fine with my PC. (OK Mac lovers, don't jump down my throat. I love my Mac. it just has a few quirks - like all computers - that need to be unravelled.)

I started up iTunes, checked my email, and looked up to see the top half of my display drop about 15 shades darker than the bottom half! I called Apple Care who told me they had never heard of something like this before and advised me to call the nearest Apple Store. I did, and like Apple Care, they had never heard of this happening.

I went yesterday evening to the Apple store in Georgetown as I happened to be near by and checked out the new Airs. The keyboard letters look reflective bu the keyboard also looked somehow cheaper (which I guess it is truly). Tough to test the usability in the dark in the store, I tried to hover over it with my jacket (must have looked pretty stupid) but it is not a real live test. So for you who had a backlit keyboard before

I have a Mac Plus 4mb that booted up fine with its system tools disk but I put in disk 1 of Dark Castle and a bomb appeared. Since then I cannot get it to boot up using the system disk that worked ok to start with. I have removed the power cord, left it overnight and still no luck. How do I reset it so it reads the system tools disk and boots up?

My six years old MBP OS 10.4.x Tiger all of the sudden the display turned black. I hardly see the content of the desktop only when there is some light on the room, looks like I have reduce the light to the Display. I have tried to reset the PRAM with the opion, ctrl, P, R key combination and it did not work. It boots-up OK, no problem with the HD neither Memory, I have not run any test on it though. I have not had any trouble on my MBP until now and I have to say I have never reinstalled the OS.

I have a 2012 macbook pro and needed to change the brightness of my monitor for my eyes, the problem is I find it hard to see the tab bar now because it is too dark. I looked on these forums and found how to change the brightness of the tab bar without compromising any of the other parts of the screen, but it is not for my particular year or model " [URL]
