Are any 24" iMac screens good?

I've just received my 2nd 24" iMac today and the screen is still bad. The first one had an even gradient from left to right (lighter on the left, darker on the right). The new one has a less defined brightness difference but has a very bad yellow area running vertically down the middle of the screen. I'm now wondering if I send this one back too, but are there any good ones out there or are all these iMacs suffering from screen quality problems. From what I've read I'm saddend to think it is a problem with ALL the new iMacs. The dilema I have is I need a machine and can't really afford a Mac Pro and 30" monitor. Please post with your views and experiences, might send this one back tomorrow.

Sorry, have to totally disagree with you there.
Did you actually adjust the brightness levels of the screens you were looking at, because if you didn't you won't notice anything in the stores. Also, using a blue background won't show anything either, must be Grey or White.
Also, My screen and the replacement had this issue, so did the three that were in the Apple Store in Bluewater(Kent).
Also, today, I popped into Comet and noticed they had a new 24" iMac Alu there as well. At first, I thought the picture was perfect, but nope, after adjustment to the brightness levels(Due to insane over head lighting) and a change of background colour, the Gradient issue was there as well.
Hmmm, must be a wide spread issue, because the Comet shop was at least 40miles away from the Apple Store, and even the guy in Comets saw that there was an issue with the screen.
Personally, I think one of the following options.
People are either unwilling to see there is a problem because it's Apple.
People are just oblivious to the problem because there eyes don't detect it so well and nothing to do with Apple.
People are just kidding themselves there is no problem, when I bet anyone that says they have a good machine, could well be a faulty one, especially if those that can see the problem had a look.
People have no problem and have been very lucky.
The fact Apple have said nothing, means squat. They seem to have a habit of keeping things quiet anyway.
Me, I hope they fix this problem because I really wanted a new 24" iMac, but right now, my money might end up going towards a PC upgrade.

Does anyone like their new iMac screen?????

I am going to be recommending a new imac for some friends and wanted to know if there is anyone that likes the new screens on their iMac?
I know only people with problems post on here, but just wanted to see if there are any happy iMac users.
thanks in advance

For the past 4 years, I've been using the Powerbook G4 laptop and I prefer the matte screen display. When I saw the new iMacs, the only thing I didn't like was the glossy screen, but everything else was awesome about the iMac. In the end, I decided that the glossy screen wasn't SO bad. The only time it's really irritating is during daytime when the light reflects off the screen. Since my iMac is in my bedroom, I can just pull down the blinds and it'll shield the sunlight from 'attacking' my iMac glossy screen. Or, you can increase the screen brightness, and it helps take away the reflections.. not 100%, but most of it.
I've gotten used to the glossy screen now, and yes, it does make my Powerbook G4 screen look quite dull. Haha. I still use my G4 for school purposes, so it's not going into the can just yet...
Yeah, that's my take on the screen. So, yes, I do like the new iMac screen.

Any external monitors as good as imac screen for text?

hi all.
this is my first mac. it's a new 21.5inch imac with a 2.7ghz i5 proc running OS X 10.7.3 and 12 Gigs of RAM (8 Gigs from crucial for $50, who can resist?)
i've got it hooked up to an external samsung syncmaster B2330 running in 1920x1080, which is this monitor's native resolution. works fine. it's hooked up via the dvi port on the screen via the mini-displayport to dvi adapter for the mac. i switch this monitor to the vga port when i want to use it as my pc monitor also running at 1920x1080. there is a source button on the monitor. very convenient.
the issue is that they text on this screen when coming from the mac is not as clear was when coming from the pc despite the fact that the vga port provides much less bandwidth than the dvi port the mac uses. i've read that the mac and the pc display text on screen using different methods. my pc uses an nvidia display graphics card. i believe mac use ati based hardware.
there appears to be much more interpolation when displaying text from the mac. perhaps this is a text size issue i'm not sure. either way i read a lot on this monitor and need it to be as good as possible for that purpose.
so the question is, does anyone have experience with an external monitor that is as good as the imac screen for text display. i can't use the thuderbolt display or a cinema display since they don't switch to different ports allowing my to use a single external monitor for two machines. i'm willing to spend up if there is a reason to do so. i'm on these computers a lot. i work from home with some regularity and my job is all about reading.
any help is appreciated.
best, c

Just wondering what Apple's stand is on the issue with a flickering and a dark area appearing on imac 27"screen - forums seem to indicate this is not uncommon - and happens through normal use - so should be subject to repair (Sale of Goods Act - 6 years)

We are just users like yourself. If Apple has stated publicly about the problems you mentioned, it will be listed on their website and/or in one of their Knowledge Base Articles.
I have a 27" & do not suffer from such a problem. You should keep in mind that these are technical support forums. Generally, the only people posting here are those with problems. The thousands/millions without problems don't ever come here.
Think of these forums as a hospital emergency room.

Are all Imac screens unevenly bright, or just faulty batch?

Can anyone confirm that they have a 24" Imac that has a uniformly bright screen, i.e. when scrutinizing it with a solid grey or white background, you cannot see any areas of the screen that are noticeably brighter than the others?
I really want to buy a 24" Imac, but having tried two that had an unacceptable brightness gradient from left to right, and having been told by the Apple Store owner that their display model also has the same ueneveness, plus having read the many posts on this board about the same issue, I am beginning to think that perhaps all the new Imac screens have this problem.
I'd appreciate it if anyone who owns a 24" alu Imac with a good screen could post in this thread.
Many thanks!

Im surprised mrtotes can't see any gradient problems on his Alu iMac! There are VERY few people reporting that their 20" or 24" iMac doesn't have a gradient issue.
From other iMac customers, including those on these forums, it seems that it is not necessarily a faulty batch, but a range-wide issue. Whether Apple decides to provide a fix for current iMacs and/or produces new batches without the issue, is simply unknown at present.
I have also read that Apple's response is that the iMac is designed for consumer-level customers and not for professionals. Professionals including graphic designers like myself will likely disagree with this. I am at a graphic design degree course at the moment and my lecturers also disagree with this statement (Especially seeing as all our workstations at university are previous generation iMacs!). The iMacs are definitely acceptable, and probably excellent for non-professional use, but if you're interested in correct colour and brightness levels for things such as design work, then the current generation iMac is now unfortunately not suitable for this sort of professional use.
I am not providing any facts here, just gathered information. I am awaiting a replacement for my 20" Alu iMac but I am certainly not expecting it to be any different.

My imac screen display is unfocussed, odd coloured and blurred (caused by rogue cate walking over keyboard). I have no idea what settings have changed or what to check. Any ideas?!

It could be a number of keyboard shortcuts, here's a few.
If the screen is zoomed, hold CNTL and scroll down with mouse or trackpad.
If screen looks like a negative, hold down CNTL OPT CMD and click 8.
Let us know how what other symptoms are shown.

Imac screen went dark after power interruption any suggestions?

My son's imac screen went dark after a power interupption (someone turning the computer off by pulling cord out of electric socket) and I can't get it to go back on. I've already tried depressing the "command, alt,p and r" keys to get a restart, and while it did restart, still no picture on the screen. Occasionally you can see white staticy lines, but mostly it is just dark. I've seen the suggestions to update software and back up data but that isn't possible as far as I can tell because I can't see anything on the screen - it is totally dark! Any suggestions? He is coming home from a trip today and hasn't had any access to computer for some time - he is going to freak

First try iMac SMC and PRAM reset, please do each of them 2x. If that does not work then try restarting in Safe Mode, this will clear some caches. You did not mention the version of OS X running on the machine, if you are running Snow Leopard then install the Snow Leopard disc in the SuperDrive and restart, when you hear the start up tone hold down the Option key and start from the SL disc and run Disk Utility and Repair Disk Permissions & Repair Disk.

There are coloured vertical lines on my iMac screen?

So, I was browsing Safari using my iMac the other day (as I always do), when my computer froze and I had to force shut down. Upon starting back up, I noticed that 1. there were coloured diagonal lines on my iMac screen, and 2. that my mac would not boot up unless I booted it using safe mode. I haven't had an issue with this iMac until now, so I am kind of concerned...
I know that this is not an issue with damage to the iMac screen because, well, when I took a screenshot using shift + command + 4, the coloured lines were still there!
So, I'm just wondering if anyone knows what the cause of this issue could be? I'm wondering if it is linked to Safari (because when I open a new tab, Safari slows down massively and my top sites selection keeps appearing and disappearing rapidly. Does anyone know what is causing this issue and how I could solve it. I hope its nothign expensive like replacing the motherboard...

Yes, it does require some disassembly. Namely, removing the glass, screen and the GPU component. Total war could probably develop temperatures too high.
I don't know how familiar you are with reflowing. This is only a crash introduction, to get an idea what reflowing might include (i.e. not a detailed procedure)...
Reflowing theory to give you some background. Here and here in more detail.
To get familiar with iMac (only steps 1 through 9 apply). After that, GPU component can be taken out, and from that point on, the work is done on the GPU component.
GPU component is then disassembled in 3 key parts. The heatsink, the reinforcement, and the video card itself.
The video card and the heat sink are then cleaned carefully using alcohol from any residue of thermal compound. Any paper stickers must be peeled off, too.
Reflowing. Videos to get an idea how it is done. Here and here.
New thermal compound is applied.
Assembly.
It is a risky approach, especially if you are not comfortable with disassembling your iMac. In that case I would suggest you do not do that at all. Still, even then, I hoped it could give some clue to the issue and you might get someone to do it for you.
Cheers

IMac screen appears to have smudges under the glass. They are not on the surface and it doesn't matter what wallpaper is in place.

iMac screen appears to have smudges under the glass along the top of the screen. They are not on the surface and it doesn't matter what wallpaper is in place. Anyone else had this happen?

The " glass" front of your iMac is really not glass, at all, but an optically clear polycarbonite (plastic) that a black border painted or possibly "printed" on the backside (to hide the strong magnets that hold this cover on) that has a metal frame glued to the back to which this frame is held in place with very strong magnets.
You use one or two small suction cups or a suction cup from a windshield mounted mobile GPS mount or purchase a small commercial glass cup, that is used to handle bare glass, to get the polycarbonite frame off.
The reason I mention the material is polycarbonite is that you should NOT be using ANY type of retail/commercial window glass cleaners on this front glass or on the LCD screen.
Polycarbonite easily scratches and clouds when using ANY conventional glass cleaning solutions.
You need to use a lint-free, microfiber style cloth dampened in warm water (completely wring the water out of the microfiber cloth to the point cloth is just warm and damp with NO water dripping at all from the cloth) and use this to get the screen and glass don't screen clean.

I recently downloaded a 10.6.8 update and a game program has now been reduced in size. It's specifications are set for full screen, but it is about 1/4 of the size. Any ideas how to fix?

In addition to the above I also recommend Apple's Pages ($19.99). I use OpenOffice and Pages and have been completely Microsoft - free for over a year now. Life is better without Microsoft.
Just an FYI John, NeoOffice is no longer free, (but it is cheap at least)

My iMac screen keeps showing pixels of previously opened documents and Safari tabs and hour or two after closing them. The shadow of those opened documents are still there hours later after shutting down and restarting my computer. What is happening

My iMac screen keeps showing pixels of previously opened documents and Safari tabs and hour or two after closing them.
Even when I swipe to the dashboard the outlines are still there when I know they should not be.

What is happening and what shall I do? Thanks in advance.

Not much to go on in your product info, but maybe this will help: iMac (27-inch): AMD Radeon 6970M Video Card Replacement Program. If not, then it's time to visit an Apple repair station.

Are iMac's good for professional video editing?

Are iMac's good for professional video editing (and these other apps)?, if so what one is the best
Software i would like to run (and run fast):
Final Cut Pro 7/X
Premier Pro
Avid
Motion 5
Colour
After Effects
Photoshop
and maybe a copple of games such as the elder scrolls online, gta 5 (when it comes to Mac/PC) and skyrim (with mods)

Yes, I'd urge you to visit your local Apple Store and ask your quesitons. You may want to speak to their business professional who may have more expertise than your everyday consumer sales people.

TS1367 Hey. My iMac screen comes on but it won't let me type my user name in. I first thought the batteries were done on the keyboard or Magic Mouse but they are both flashing. Cam anyone help

Can someone help. My iMac screen comes on but won't let me key in my details. I first thought my batteries were done but the light on the keyboard and Magic Mouse are flashing. My user name appears but I can't insert my password

Paul_31 is correct. The problem is almost certainly a Bluetooth connection issue. The flashing green lights mean that a connection cannot be established. You want steady burning green lights. Using a wired keyboard and mouse will allow you to troubleshoot that issue. A quick check would be to see if your "problem" keyboard and mouse can connect to another-different Mac. If they can then the issue is in you computer but if they can't (and I suspect that will be the case) then the problem is with the keyboard and mouse.
