TFT LCD MONITOR GOING MAGENTA (PINK)!

my monitor keeps going a magenta colour every now and then and then seems to switch back to normal. however its begining to get more frequent. i can still use all the apllications though and it runs as normal, just not sure if this is a monitor problem? any ideas?
emma.

The fact the symptoms are the same doesn't necessarily mean the problem is the same. There are some displays, for example, which cause a magenta color cast on almost any Mac but which work perfectly with some and with all PCs. I have one such (a MAG LCD) and it is clearly an issue with the display and compatibility with Macs. The same symptoms with an Apple Cinema Display is clearly not a compatibility issue, nor a generic brand-based one.
On the other hand, a general color cast can often be caused by a slightly loose connector, or by a damaged connector causing an intermittent or failed contact on just one pin. It's been found, for example, that the DVI/VGA adaptors supplied with minis can result in such poor contact, giving odd display issues which disappear when a different adaptor is used instead. Similarly with some minis (particularly the early ones I suspect) if the connectors are not done up tightly.
There is nothing to say that in any specific case such as yours, the root cause of a display issue such as this could not be a hardware issue, or firmware, or indeed MacOS settings relating to color balance and saturation. It's not a generic issue relating to all similar systems of course because otherwise we'd see it reported with all minis of the same specification when used with all ADC displays of the same type.
Given you have an authorized service provider working on the problem, which puts them in a situation where they can at least get their hands on the equipment and run tests and try possible solutions, it seems to me reasonable to let them keep going with it - at least to the point where they can give you an educated guess as to where the problem lies.

The manufacture date of T400 WXGA TFT LCD monitor

I ordered my new T400 in October, 2009, and recived almost three weeks later. Definitely, it took longer time than they promised me. Whatever, I got the laptop, finally.
Now I have a question about the monitor. I used a software named EVEREST 5.30 (http://www.lavalys.com) to check the information of the hardware. Everything is okay except the monitor. It says the manufacture date is 45th week in 2006? Can you believe it, a monitor, potentially, made three years ago for my new laptop???
I called lenovo, and they told me the LCD factory is probably using the same date for all monitors of this kind no matter when they're made. Can you believe it?
They didn't have such complain before. If I can find different case for T400 with same kind monitor, they will accept my complain. Am I responsible to prove that or lenovo's?
Anyway, we can do that, right? Hey, all T400 people, it's time to show our power! What's your manufacture date of the WXGA TFT LCD monitor? I will appreciated if you can post your LCD manufacture data as well as when you bought you laptop! Many thanks to everyone.

My point is that even if the LCD sat for 15 years if it wasn't in use it wouldn't be prone to any more failures then one which is only a year from manufacture with the same amount of hours on it.
Though I don't have intimate knowledge of every laptop which Lenovo has manufactured but I have personally swapped a T61 15.4in widescreen into a T500 15.4in.
It is probable what they are saying is that your laptop screen could not be that old because it is improable one would be in storage for that length.

What you said could be true.
However, I don't think customers prefer a LCD made several years ago, even the quility may be better. I have only one-year warranty, who knows what will happen after that.
BTW, the "old" LCD I mentioned doesn't mean a used one.

HPw2207 Monitor Goes To Sleep & Won't Wake Up

My HPw2207 Wide LCD Monitor goes to sleep and won't come out of the sleep mode. The screen is blank and won't respond. I have to unplug power and reboot the HP Desktop to get the monitor to work again. Once the monitor is timed to sleep the same thing happens and I have to reboot the system again. The computer is an HP-Pavillion d4999t (KC836AV-ABA). I also have an NVIDIA graphics card on the system. This started about a week ago. I checked the cable connection and it appears to be fine. I tried downloading an updated driver for the monitor for Windows 7 from this site but it encounters an error when trying to install. I have set the sleep mode to "Never" for now hoping that this will at least keep the monitor awake in screen saver mode. I need some help.
Thanks,
Bob

Hi:
Thanks for your nterest in the problem. Yes, I have tried pressing both the power button and the spacebar to bring the monitor out of sleep mode. Neither works. The power button is non responsive at this point. Shutting off the monitor and restarting does nothing as well. The only way to get the monitor out of sleep is to disconnect all power and cold start the entire system. However when the monitror goes back into sleep mode the system freezes up again.

Can 15" LCD TFT studio monitor be used with my G4?

I've acquired a nice 15" Apple LCD TFT studio monitor and would like to use it with my G4 but have found that the connections are incompatible. Are there any adaptors i could get to resolve this issue?

To get the connector terminology, take a look at the first page of this illustrated guide:
HT1825- Power Mac G4: Display Compatibility
To find out what can connect to what, look up "Your Mac" \[Column] Vs "Your Display" \[Row] in the Matrix that follows page 1.
To find the identity of your display card, use Apple System Profiler.

LCD Monitor for Video Editing: Resolution Concern

I am trying to select an LCD monitor for my newly built computer. I have zeroed in on the DELL SP2309W, 23" Full HD Widescreen Flat Panel Monitor with Webcam. The optical resolution is Higher than Full HD at 2048 x 1152.
It is my understanding that Higher than HD Resolution is good for multi-tasking (but DVD movies get stretched and therefore the quality of your videos goes down.), but is it good for video editing with Premiere Elements 7 or 8? Should I be looking at monitors with 1920 x 1080 resolution?

If you run in anything other than the LCD's native resolution your graphics card will be resampling the image. This inevitably distorts the image as pixels must be discarded to create the display. Typically this softens the image.

Quality of screen color flashes after connecting to external LCD monitor

After connecting my Powerbook G4 to an external LCD monitor via s-video, the quality of the image on the built-in screen flashes back and forth between what seems like a 8 or 16-bit image and a 32-bit image. I have run the hardware test and everything checks out fine but the image is grainy and washed out and only sometimes returns to normal. I have also reset PRAM and PMU to no effect, as well as tried recalibrating the display. And oddly, the external display is fine.
This is terribly frustrating as all colors are washed out and I can't truly gauge what I am doing design wise. Any help is greatly appreciated.
Thanks

Thank you, Silly Rabbit. I actually only hook the Powerbook up to the external monitor (LCD TV) to watch movies, show photos, etc. I don't actually use an external monitor on a daily basis.
Your suggestion is a good one, which I appreciate. I am going to the Genius Bar this afternoon, so hopefully they can provide a solution for the built-in screen.
Thanks again!

External display HD LCD monitor vs HD LCD TV ??

Hello All
I'm needing to up-grade me second display and, have been shopping around.
In my shopping I'm getting mixed thoughts, I finding HD monitors and HD TV's so, I'm hoping somebody can point me in the right direction, I'm finding HD monitors in the area of $200. but, all the HD TV's $300. + , is there any real advantage of one over the other ?
I know just going with a standard LCD monitor would not be a good option, it's the HD monitors
that added to my future purchase confusion.
Thanks for any advice and or recommendations

They will probably both do as monitors. The Acer is a Computer Multisync Monitor, claiming to have a full resolution of 1920x1080. It is probably a progressive scan device, with some image processing on board, since they claim "Max. Refresh Rate 60Hz" on the Acer web site, so if you'll preview interlaced video on it, it may have the artifacts associated with standard poor or nonexistent de-interlacers. But it maybe o.k., specially if you are going to output most of your work for the internet, true Multisync Monitor maybe a good thing.
The Samsung is almost a TV set. It appears to be a 1680x1050 monitor. The bells and whistles appear to be associated with the HDTV tuner. As an ATSC tuner, it will have to tune the standard US ATSC channels and decode the standard 18 ATSC formats, including 640x480i30, 704x480i30/p24/p30/p60, 1280x720p24/p30/p60 to 1920x1080i30 and 1920x1080p24/ p30. But all this is converted into the monitor native 1680x1050xwhatever scan rate. From the HDMI inputs it will probably depend on drivers running on the graphics card on the MAC. Make sure that they have MAC drivers for this one, often they have just Windows drivers for these monitors.
I have a 26" Samsung, without the tuner and speakers, as my second monitor, to preview TV destined footage. It's resolution is 1920x1080, and it does an excellent job to show any artifacts that would show on TV.
I would recommend seeing the inputs before ordering the monitor on the WEB, because the most important characteristics are usually unavailable reading the specs. Also check about MAC driver availability.
Best of luck.

FrameMaker and LCD Monitors

Hello,
Just wanted to get your thoughts/opinion(s) as writers in using FrameMaker on LCD monitors. Specifically, I've used word processing and desktop publishing programs on CRT monitors for years. I've never had any problems whatsoever. Recently, my employer provided me with a 20 inch widescreen LCD monitor. I'm now having a difficult time with it because of the higher resolution (e.g., headaches and the like). As you all know, a lower resolution only distorts or stretches desk on LCD monitors (which is why I guess I've avoided these monitors for so long). Please note, I have bad eyesight and wanted to see if others may have ideas to address this issue. I've given the monitor two weeks and things haven't improved. I'm just concerned/frustrated because I know the world is going in the direction of LCD monitors.
For a solution, I've thought about a square like LCD monitor; maybe at 17 inches to address the problem. But I'm wondering if I'll still be at the mercy of the native resolution. Just to let you know, I've tried all the display scenarios to address the problem (i.e., appearance, settings, dpi) without success. Just miss the 800/600 resolution I had in the past due to my bad eyesight.
Any ideas or thoughts are most appreciated. Thank you very much for your time.
Paul

Paul...
Here are some ramblingthoughts on your issue. They expand on the good advice you've already received, and thus do not dispute what others have said.
Make certain your drivers for the graphics card are the latest and greatest. This is the first step you should take. You probably have already done that. If not, go do it. But check the next paragraph first.
If your graphics card has a DVI output, by all means use it. If it doesn't, opt for a different graphics card, preferably one with two DVI outputs, known as a dual-head graphics card. I address this again below.
Life is too short to drink cheap wine. It's also too short to spend a professional career working with inadequate computing resources, especially when you consider the cost of the capital outlay versus the salaries and the wasted time fooling around trying to make things right. If your employer has artificial limits on spending, go make a business case for better gear.
You already seem to understand the concept of the monitor's native resolution. High resolution monitors are best for image processing, when programs like Photoshop are used to edit photographic images. For text-based work, they're the wrong way to go, as you've discovered. Part of the problem is that many web pages and all operating systems seem to be stuck with a one-size-fits-all set of icons, menus, page sizes and the like. With Windows, you get two choices of text size, but those choices don't apply to all text instances and only in the operating system, not in the applications that run on top of the application. So driving a high resolution monitor at its native resolution results in tiny text, icons and the like. I get some email messages that I cannot read because the very popular marketing company that creates them uses what must be 4 point typefaces.
I have dual 20.5" Samgung monitors with 1600x1200 native resolution on two of my workstations. They're beautiful monitors, but I would trade even-up for the same monitor with 1280x960 native resolution. One thing that's nice about LCDs, by the way, is this. If you get ones that pivot clock- or counter-clockwise, and many do, you can easily run them in portrait mode by rotating them and changing the settings for the driver. My FrameMaker workstation has one monitor set to landscape orientation and the other to portrait mode. Try setting a 17" CRT on its sidegood luck!
LCD monitors will ONLY look their best when the image is displayed at their native resolution, or perhaps in some cases, at a submultiple of the native resolution. For example, a 1600x1200 monitor might look OK when the graphics card is set to 800x600. In my case, that makes the icons and windows appear too large, though. Something in-between is best for me. I doubt, however, that you have a 840x525 choice, but if you do, try it.
Sheila asks about your video cable. An LCD monitor *should* be driven by a graphics card with a DVI (digital) output. Otherwise, the signal must be converted to analog (VGA) and back to digital for display purposes. Since the image is inherently digital to begin with, converting to analog video and then back to digital has its obvious drawbacks. I'm not sure if a modern graphics card can properly identify the connected monitor though a VGA cableit's been so long since I used a CRT and a VGA card that I've forgotten.
A CRT monitor also has a "native resolution" based on the pitch of the phosphor triads and the shadow mask in the tube. Because that was an analog interfaced world, and CRTs are relatively "soft" compared to LCDs, the effects of non-native scan rates and resolution settings were not as troublesome or as obvious as they are for LCD screens. Once you get the settings right on your LCD display, though, you will NEVER consider going back to a CRT display.
It's probably too late to lobby for this, but if I were you, I would strive to get a "dual-head" graphics card, one with two DVI outputs, and put two identical monitors side-by-side. Once you've experienced a dual-monitor setup, you will never be happy with just one screen.
Setting the graphics card resolution for a 16:10 aspect ratio in any other than the native resolution of the monitor will result in "aliasing" artifacts, which may be what you mean by "distortion." The simplistic way to describe the aliasing effect is that some elements of a character inevitably fall in the "cracks" between pixels. When the image resolution setting matches the native resolution, the video data from the card "lines up" perfectly with the pixels, giving the most accurate representation. The other type of distortion that you may be referring to is due to a mismatch of the aspect ration associated with an image resolution setting versus the aspect ratio of the screen. In such situations, a "truly" round circle would appear elliptical on the screen. This is what Winifred is describing. You cannot expect acceptable results with any graphics card setting whose resolution aspect ratio is , relative to the display, mismatched. You must use a setting that corresponds to the 16:10 ratio.
Another way to understand the artifacts associated with aliasing is to imagine viewing a checkerboard through a piece of wire fencing with a square pattern laid on top of it. When the size of the squares in the fencing material are the same as the checkboard squares, you can make things line up and see all of the checkerboard. If the screen wire is a different size, then there's no way to place the wire over the checkerboard without covering some of the squares with wirethat is, unless the pattern in the fence is twice the size of the square, ot four times, and so on.

Problems with two new LCD monitors and my G5 Power Mac

I bought two of these Westinghouse Digital LCD monitors:
http://www.macaddict.com/issues/2005/11/reviews/lcm
When I plugged in the first one, my Mac's power-on light was on, but the Power Mac G5 (1.6 ghz, 1.25 gb RAM) wouldn't boot and the light wouldn't go off. No problems once I unplugged the first LCD monitor. I plugged it into the second one and the Mac turned on once it was plugged in, but at least I had an image. But the computer was frozen; I unplugged and re-plugged it into the first LCD and had an image, but again, it was frozen.
Any ideas why this is happening? I'm going VGA into the DVI via Apple's adaptor.
Help and thanks,

Okay, well this is interesting. If I take the brightness down too much, I see "ghosting" on EVERYTHING, including text. Also, when I shut down the Mac with monitor 2 plugged in, the one that when I plug in the LCD it turns the Mac on, it restarts the computer. I did this twice to insure I wasn't just hitting restart by accident. I'm calling tech support Monday (Westinghouse) and I think I'm taking these "good on paper" 16x9 LCDs back to Best Buy for a full refund. Then, I'll buy something different. I'm bummed out...

32" LCD Monitor and mac mini

I'm considering building the following home theatre set up:
mac mini + EyeTV tuner + 32" LCD Monitor.
I'm pretty confident the mac mini will work no stress with the EyeTV tuner. However, I don't know if I will get as much resolution (1366x768) on the monitor, either watching tv or just using it as a computer. Can anyone forsee the result or some problems with this set up?
Cheers,
Rodrigo

Thanks BSteely.
As far as the display goes, I'm just after an LCD monitor, I don't need any of the TV features since I have the EyeTV to do the tuning (digital or analog). I'll have a good google to see what others report with monitors but if you have some suggestions I'd love to hear them.
Thanks again,
Rodrigo

External LCD monitors with DVI PowerBook: Banding Issues

I have a DVI PB and would like to attach an external LCD monitor. I've looked at both Samsung 20 inch and ViewSonic 19 inch versions but whenever I attach them, I get "banding" around the edges of the external monitor. Tonight, I went to CompUSA to look at the Samsung 204B 20 inch. Taking my PB with me, I hooked up and set the resolution to 1600 x 1200 and the Samsung had huge, fat black banding all around the monitor. If you don't know - banding looks like a large, black border going around the screen. The sales guy pushed some auto-set buttons (which is said always work to remove the banding) but it didn't fix the issue. Any suggestions? Is there some secret that I'm not aware of on how to attach and use an external LCD monitor with the PB? One note: I did set the resolution down to 1280 x 1024, which worked fine to remove the banding but it monitor looked horrible. Not the best resolution for a large monitor.
Thanks,
B. Rose
TiBook 800 & iBook SE Mac OS X (10.4.6)

Hi, Bill. I can't speak to whatever happened with the Viewsonic monitor, since you didn't tell us about that, but it sounds as though the Samsung was in display mirroring mode rather than extended-desktop mode. The F7 key on your Powerbook's keyboard toggles an external monitor between the two modes. In mirror mode, the external monitor displays exactly the same thing as the built-in display. In extended-desktop mode, it functions as a separate portion of your desktop, and you can drag things (windows, icons) from one monitor onto the other. If you're going to use both displays, extended-desktop mode is probably what you'll want: why keep two copies of the same thing in front of you?
In mirrored mode, the fact that your Powerbook's display has a maximum resolution of 1280 x 854 means that only 1280 x 854 pixels of the external monitor can be used — leaving wide black borders of untapped pixels around the copy of your PB's display that's centered on the external monitor. In extended-desktop mode, the external display's native resolution of 1600 x 1200 can all be used, provided that your 32MB of VRAM is sufficient to drive the total of (1280 x 854) + (1600 x 1200) = 3,013,120 pixels, at the bit depth you've selected. (You might have to use the extended-desktop mode in Thousands of colors, rather than Millions.)
Another issue that comes into play with display mirroring is that the 4:3 aspect ratio of the 1600 x 1200 Samsung is different from the 3:2 aspect ratio of the Powerbook's display. If you set the Samsung's resolution to 1280 x 1024 to match the pixel width of the PB display, the top and bottom of the Samsung will be black bands, because the PB isn't manufacturing any pixels to fill those bands. And it will be blurry, because the Samsung has to interpolate to make 1600 pixels look (sort of) like 1280 pixels. Unlike a CRT display, the actual number of pixels in an LCD is fixed. When you change resolution settings on an LCD from its native (maximum) resolution to anything less, the image is always blurred. Only the native resolution can be really sharp.

24" Widescreen LCD Acer goes blank

I have a 17" Macbook pro and a 24 inch widescreen LCD monitor by Acer (al2423w). I am trying to use both monitors in mirrored mode (lid up) using a usb mouse and the macbooks keyboard.
I have tried connecting the acer through the dvi-vga adapter and I've tried a direct dvi connection and the same thing happens with each - the acer works and then goes blank. Now I know the acer works because I used it as the primary display for my PC but for some reason when connected to my mac it works perfectly/beautifully/wonderfully for about 10 seconds... and then goes blank without any blinking error lights, or messages.
The monitor is detected, connected, powered, and even works and displays in mirrored mode but then for some reason stops. While it's working I can even change the resolutions and refresh rates without any problems.
I would greatly appreciate any explanations for this issue.

Hp w2338h lcd monitor

I have an HP w2338h LCD monitor which goes blank after a couple of minutes. Is making a buzzing noise too. I suspect is the inverter. What tipe and how should I change it?
Thnaks

Hello laszlon,
The first thing I wonder is if the monitor is under warranty if it is you should contact HP for repair / replacement. If you are outside of warranty and are looking to venture on your own the issue could be the power inverter. You can search ebay for the monitor you have and power inverter or standard google searches.
When the monitor goes blank can you hold a flashlight to the screen and still see an image?
