20" ACD Sparkle/Glitter/Grain/Hazy Issue?

I used to own a MacBook Pro Core 2 Duo 15" with a very grainy matte display. I posted a thread about it here: http://discussions.apple.com/thread.jspa?threadID=723534&tstart=0
Anyways, I returned it because I couldn't stand to look at it anymore and now I'm considering getting a Mac Pro with a 20" ACD along with it. I looked at the 20" at the Apple Store where I was returning my MacBook Pro and I noticed a little bit of the sparkles or grain or whatever you call it but, it was not as bad as my MacBook Pro... but yet it was also not as clear as the iMac display. The screens I was looking at had a lot of fingerprints/dirt/scratches on it so that may have been the reason for seeing this effect on it.
Can anyone who owns a 20" ACD confirm whether their screen is really smooth and clear (if they keep it clean) or if it's more like I'm describing in the MacBook Pro thread. Any helpful descriptions or observations about the quality of the display, please let me know. I don't wanna spend that kind of money on a display that's too sparkly looking.
As a test... try opening a blank Safari page and move it around on the screen... do you see a static pattern that does not move. Then note whether this is hardly noticeable or very noticeable to you. Thanks.

Thanks Gareth! I went to Circuit City, Best Buy and Staples to check out LCDs and the only one I thought was worth buying was the Apple 20" Cinema. I looked at resolution and build quality and the 20" ACD had both a nice high resolution display and the build quality was very good. Excellent case, solid, sturdy stand, smooth hinge and excellent control buttons on the side. So I got it! You're right, the grain is there and is noticeable but, only if you're looking for it. I was using it last night and the grain wasn't really even bothering me at all... I think the bigger pixels help by taking up a bigger area on the screen thus minimizing the effect that the coating has on the display image.
One thing that I am a little concerned about is that the left side has a slight cyan tinge to it which makes title bars and metal windows look slightly blue-ish on that side. If I make a full screen Safari window I can see the color change from one side to the other and the contrast is a little lower on the left side as well. It's really weird when I move a window and watch the hue change a little. It's not that big of a deal but, if I can convince someone that it's defective maybe they'll give me a different display (and hope the new one doesn't have a BIGGER problem). Oh, and right now I'm still waiting for my Mac Pro so I have it connected to my PowerBook G4 (32MB of VRAM) so I dunno if that could be causing this issue. Anyone else have a problem like that?

Applying sparkle / glitter effect to text and background in FCE 3.5

Hi Guys -
I am working on a project which requires the title of the movie to sparkle and glitter. Is there an effect I can download or is there a way to make text / background appear like it is sparkling and shimmering? Think of movies such as Priscilla Queen of the Desert and The Birdcage (don't ask) for inspiration. Any help is welcome!

Thanks for your reply, I'm pleased that there are effects out there - do you know any of their names etc so I can track them down online. I will also have a play around with livetype.
Any further help is always welcome!

Ipod touch - Glittery screen !

Does your IPT screen look "glittery" with full brightness on a black background?
Picture (it shows more than you can see in real life) - you have to look really close to see it in person.
It's not dead pixels (or stuck), there's one stuck pixel on the picture tho, but i'm talking about all the "glitter"... Seems like the backlight is getting trough some of the pixels (which it shouldn't) I've seen pictures on IPT that doesn't have this problem
Do you got this?

Its NOT dead or stuck pixels.....I posted before about 'green sparkles'.
They are microscopic particle which catch the backlight....they vary in size (pixels do not) and as you angle the screen they come and go and also change colour from red to green to blue at the specs sit over different sub-pixels dependant on screen angle and viewers eye line.
A stuck sub-pixel will remain lit and very obviouse on a black screen regardless of angle and backlight brightness. Some people maybe really unlucky and have both but they are distinctly different. One is a screen fault Stuck/dead pixels) and one (the sparkles) are an assembly issue. I have an 8gig week 38 and a 16 gig week 38 one is a 1D38 and one a 1A38. I also had the thought that the particles may be present in the coatingon the front membrane of the LCD and a manufacturing fault direct from whoever makes these screens for apple. I have kept both units as they are only noticable on max backlight (that washes out the blacks) and with your nose pressed against the screen. Trust me having had 3 MacbookPro's with stuck pixels and 2 Macbooks with the same i'm well aware what they look like and this particular issue is NOT stuck or dead pixels.

PT890 Neo + Nvidia GTX 260

Hi there.
Someone knows if a GTX 260 svga (Sparkle Calibre) has incompatible issue with an MSI PT890 Neo mobo?
I got both, and now many games get stuck or crash. Previously, with a 9400GT no problem at all.
I also have a Corsair TX-650W (for gamers) installed.
Problems come out both with XP-SP3 and W7.
For example:
Alice in Wonderland (The Game) get crashes every 5 minutes.

THAT'S THE FOCAL POINT
See what i'm using
I know, i'm mad ... going to buy a CoolerMaster HAF922, hoping can resolve... ... ...
When i took the GTX 260 really didn't know it was a portable oven!!!

Issues with MacBook Pro and ACD 30"

Does anyone else have a 30" ACD hooked up to their MacBook Pro yet? My 30" is having some issues with my new MacBook 2.0ghz and I would like to see if I am the only one.
#1) I am getting horizontal white lines flickering every minute or so. This does not happen on my 17" PB G4 1.67. This is more distracting than the "dancing pixel" problem.
#2) The bottom of the reflection of the album art in FrontRow is distorted when I use the 30" as the main monitor. I posted a photo here: http://members.cox.net/5337/fr.jpg - the "distortion" changes everytime I change song and it different everytime. It occurs on all the album work.
PB G4 1.67 - 17 Mac OS X (10.4)

I think you were responding to Bob Smith, but regardless, I found the same information.
One thing I've noticed, and mind you, I don't have my MBP yet, so I'm working from photo's, but I am bothered by the DVI connector being so "exposed". I would have somehow put a sliding cover on it, or at least one of the plastic end caps. I know, I will most likely never use my MBP on an external display, HOWEVER, I don't like the idea that all sorts of gunk and stuff can easily get jamed into that big ole connector!
I think an air can or a fine photo brush should be part of your "kit". Just my opinion...

Sounds like you may have been in extended display mode. If so, all you had to do was drag a window to the projector display. Or, if you wanted mirrored mode, in display preferences select check mirror display.

PowerBook G4 15" and 23" HD ACD usability issue

I am using a PowerBook G4 aluminium 15" with screen resolution 1280 x 854. At home this system is attached to an 23" HD Apple Cinema Display with resolution 1920x1600.
The issue I have is the need to always manually resize the windows when you switch from road use to home. I am normally not opening up program windows to cover the whole screen size on the ACD. So I have to manually set the program windows again every time I attach the PowerBook back to the ACD.
Is there no way that this could be done automatically? Meaning: that the screen windows open to a set window size when the system is used on the ACD?
This is not a fatal issue, but a very annoying one, stemming from the fact that the resolution of the PowerBook LCD and the external ACD are different. Sadly there is no PowerBook 15" with 1920x1600 resolution such as in the Windows world.
Any ideas?

The plus is that you and your wife will have basically the same product. Did you purchase Apple Care? Highly recommended by me. If I had it, it would have saved me a small fortune. This is a PowerBook forum so I'm not familiar with the problems with, or the utilities on the MacBook. So may I offer a few suggestions: if it is the same, it is imperative that you run disk utility, to verify and repair permissions and verify and repair disk, as well as the Apple Hardware Test, from your system disk, on a fairly consistent basis. A good third party application is Disk Warrior to keep your hard drive working optimally. Also, keep as much disk space as possible unused, 10% minimum, if not more. And back-up, back-up, back-up your hard drive. All the best!

New issue with ACD 30"

Hey guys,
I've been looking around and I've seen a lot of threads about this similar issue but not found a solution to it . Rather than chiming in with those however I'm starting a separate thread because I believe my experiences are slightly different to what others have seen .
I have a 13" MacBook Pro, 2009 I believe and a 30" ACD - both bought new this year around 6 months ago and have both up until now been performing wonderfully . Most of the time I have the ACD connected to my PC as that is what I do the majority of my work on but when I have editing to do in FinalCut I switch over to this MBP and hook it up to the monitor via the dual-link dvi/mini-dv thing . As I say, has been working fine until now at the 30" ACD's native resolution .
The monitor is now exhibiting the blinking black state that others experience, occasional graphical corruption and green patterns along the lower third of the screen . Interestingly this only happens at resolutions that are not 1280x800, the native resolution of this MBP - it remains completely stable at this resolution with no blinking or green patterns . Anything higher or lower causes it to freak out .
If I connect the display back up to my PC, it again resumes working fine and stable at its native resolution .
If anyone has any clues or suggestions I would greatly appreciate it !

so it turns out, the duallink dvi adaptor works fine if I don't plug it in all the way !
I hope this helps some of you guys .

Colour issues - 23" ACD

Hi gang,
Another question, if you don't mind.
I mainly work on 3D Architectural presentations. The clients are handed a digital files and I never deal with the printing of the images. Some go onto large billboards, some even get framed .
In most of the cases the colour is "close enough, good enough".
i am finding that the ACD is much warmer than the MBP, even if set to the same colour space; I mostly work in Adobe RGB 1998.
I don't think I need to calibrate the display with a hardware device (like the spider) as I don't output, but which do I trust more?
I am afraid I'll end up with images being overall too blue or too yellow depending which screen I rely upon.
Any ideas? Happy to hear about your experiences.
cheers
i.3d

I see your point WRT the brightness moving to zero, but my question remains, how long should this decay go on and what is acceptable?
I will do another experiment tonight turning off all power management on the display to see if indeed it ever does settle. I'm going to note the starting level (no adjustment after the display has been running for at least 30 minutes), then after 1, 2, 4, 8, and 16 minutes post slider adjustment. If it continues to decay after 16 minutes, I would think that is unacceptable.
Sound reasonable?

ACD 30" has wake from sleep issues

I have an apple cinema display connected to my mac mini by the Mini DisplayPort to Dual-Link DVI. Intermittently it will not come back. It comes up with line filled color bars and sometimes scrambled. Sometimes it will come back looking perfect. If I unplug the minidisplay port plug and replug, it will come back perfect. I have tried to isolate it in some way. I have used two different machines first my MBP and then the mini, a different dual Dvi adapter and a different cinema display and intermittently I still get the issue. I think it has something to do with the mix of the screensaver, sleep display time and the computer sleep time. Some mix is jinxing it. Any ideas? I appreciate your help and input.

here is one the screens I get: http://www.postimage.org/image.php?v=aVGCNB0
Sometimes the images move or the lines wiggle, sometimes it is just immobile. I think it has something to do with the mix of screensaver (using the iphoto screensaver choice) and the display sleep and/or computer energy saver sleep.

Need help with 24" ACD USB/Speaker/iSight Issue

My 24" Apple Cinema Display is about six months out of warranty.
I've tried both my 15" i5 MBP and my MacBook Air with the same result: The USB ports at the back are dead, I get no sound from the monitor speaker (it still routes sound through the laptop speakers, such as they are) and the iSight appears dead as well.
I've tried restarting the computers and monitor; no result. I have not tried resetting the PRAM, etc., as I would imagine the same problem would not exist on two systems simultaneously.
Would anyone be able to give me an idea of the problem without my carting it to the Genius Bar first?
Since the display works normally otherwise - the marvelous display itself is unaffected - I have to assume that the problem lies either in the USB cable or connection, or in some sort of internal USB/Speaker/iSight bus. If anyone knows how the current crop of ACDs is constructed, or if you've taken yours apart, I'd be pleased to hear from you.
Thanks for your time!

MBP and 23" ACD Issues

If I start Bootcamp with my MBP screen shut I get all sorts of black screens before Windows Xp sp3 starts completely.
Sometimes it never comes up.
Also with screen shut Xp will not shut down but hangs on the Windows is shutting down screen.
With the MBP screen open everything runs ok.
I have run chkdsk and all is well.
Any ideas?
Thanks ... Ken

Thanks for the suggestion.
I did not see an option to override the standby option in Xp. But I am NOT an Xp person.
If I am using the MBP with the lid closed and boot into Xp and never open the lid I still get all kinds of black screens before Xp starts. I need to keep moving the mouse to get it to continue.
Then it always hangs on shutdown from Xp.
Perhaps it is sensing the lid being closed and going into standby.
I will look into an option in Xp to disable the lid closed standby option.
Has anyone used an external monitor with Xp on a MBP?
Thanks ... Ken

23" ACD Power Button Issue / Display Options Missing

One time my dual 2ghz power mac froze upon coming out of sleep mode so i held the power button to power down the computer, but before i did that, i touched the power button on the side of the monitor, hoping to somehow bring up the password prompt out of sleep mode but the screen stayed black and the cursor / ball would just spin for minutes.
I used to turn on / off my computer and the display would automatically go on / off with it, but now i have to manually power up and down the monitor. And in the system preferences, there is no longer the options section where i can choose what the power button on the monitor does.
Can anyone help out with why this is happening? A million thanks in advance.

Your computer no longer has USB connection to the monitor. Do the USB ports on the back of the monitor still work? Sometimes unplugging everything, including the power cord, from the monitor for a while will fix it temporarily.

I give up, 23" ACD's are just to problematic.

This thread is just my experiences in trying to find an acceptable display in the 23" HD Aluminum series, there is no scientific testing just my personal viewing results after testing 12+ displays and a whole lot fo restocking fee's. Half of the displays were tested from Apple the rest were tested from purchases at another authorized box store reseller.
I am currently using a 23" HD Cinema display that is roughly 12 days old which suffers from an array of issues that are far to common with these panels, in 12+ 23" ACD's every single one has had issues, here are some general findings and while every one knows of these already I just thought I would consolodate a bit since I tested so many 23" apple displays.
Most common issues:
. Stuck Pixels (White/Red) every display I have tested has at no less than 1 stuck red and up to 5 red/white, this does not count dead (black) pixels.
. Extreme backlight bleeding: I have yet to test a single 23" ACD that does not sufer from serious backlight bleeding, I have seem (1) out of 12+ that has an acceptable level of bleeding, but they all suffer from serious problems in a dark room set to black background.
. Ghosting: This actually was totally random, lets say out 12 displays tested, 5-6 displays ghosting while the others did not. The odd thing is that some of the displays ghosting was very minimal and some of the displays were terrible in this regard. I have also seen some displays that only suffer from ghosting in select areas of the panel.
. Pink Hues: This is common, almost every panel I tested suffered from this issue, but it varies greatly from display to display, some of the displays would be extremely pink while others display a moderate hue. very few of the tested displays offered even grey tones which is where the pink hues are most noticible.
. Verticlal and Horizontal banding lines: This was the most rare of the issues I have seen, maybe 2-3 panels I had tested and even the current one in my posetion suffers from this issue. In a dark room with a black background you can see un even lines that look like faint grey/black tones running both horizontal and vertical. I had been told by apple this is how the technology works, but that was clearly wrong since the banding is un even and it did not appear on the majority of my displays tested.
. Brightness/Contrast: This is a problem for me, each display I tested had varying results, none of my tests were scientific just to my eye type testing. But some displays were really bright and looked vivid and sharp while others looked dull and and did not have the brightness the others panels did, this was dissapointing, because once you get a good one you can see how great the high brightness looks on these displays/
In the end, I have tested far to many of these displays and have payed far to much money in restocking fee's to apple in hopes of finding an acceptable display.
I must be honest and say at 1st I had very high standards and felt that for 1299.00 I should be getting a 100% perfect display, but that was not going to happen no matter what brand I went with, I simply did not understand the technology enough and where it is at in regards to what is acceptable these for this point in time with an LCD.
I have seriously lowered my standards and am willing to accept some backlight bleeding, and even a stuck pixel or 2 (though I would like to not have any pixel issues, I can live with the backlight).
I also have (2) 20" Aluminum ACD's that are for the most part perfect and (4) iMacs that have perfect screens so this leads me to think its just that the 23" displays are of poor standards.
I am not researching the Eizo 24" widescreens in hopes of finding a display the does not suffer from banding, ghosting and poor backlighting. Its a bit more money, but why settle for s display that has so many issues just to support the brand, in the end should we have to settle at all?
Cheers!

Well,
Its a pretty looking display and there is a 50/50 chance you may get a panel that is acceptable for you. Alot of this really comes down to how sensitive you are to these sorts of issues and greatly dependent on what type of setting the display will be in.
As an example, most of these issues are not noticable in a bright natural setting with sunlight, pixel issues are random so again its all about chance.
I wanted this display to be great, its gorgeous and looks great with a G5 tower, but its not all that its cracked up to be. Take this with a grain of salt, there are plenty of people who love their 23" ACD's, I am just simply writing about my situation.
Keep in mind, if you purchase from the Apple store and find any of these issues I wrote about, you will be subjected to a 10% restocking fee each time you want to swap it out, so 129.00 a pop to see if you got a decent one.
I would suggest if you set on a 23" buy from a reseller that does not charge a restocking fee incase you get a display with issues.
One last thing, if your deciding between the Apple and the Dell, they both use the exact same LG panel, the only differences is the electronics of how its backlit and such (this is fact), the dell can be found for hundreds less if you catch them on a good sale day, just one thing to consider.
Cheers!
