LED of LCD Display

Many of the new mac books and the new cinema display uses LED, but some told mw that iMacs are just LCD.
Is the iMac LED or LCD?

LED is just the method of backlighting. The display panel is still LCD. Typical LCD panels (including iMac and some other Apple LCDs) still use CCFL (Cold cathode fluorescent lamp) for backlighting. The unibody MacBooks (and the LED Cinema Display) have moved on use LEDs.
So they are still LCD displays in either case. The only difference is the source of the backlighting. LEDs are supposed to provide more even lighting, if designed right. They also do not fade in brightness over time and use, like CCFLs, and are more energy efficient.

LED display has blue cast compared to 23" LCD display

Just purchased the 27" LED Cinema display. It is side by side with my 23" LCD display. The colors are dramatically different. Is there some way to calibrate the new 27" monitor so that it has the same appearance as the 23" LCD or is the technology so different that they will never really look similar? I have a Mac Pro 2 X 2.4 GHz Quad-Core Intel Xeon.
thanks
russ

Yes, they do frequently have blue tints which cannot be calibrated out. I had to return two of them because of the problem and eventually just got my money refunded. I was told that Apple Engineering had no fix other than to suggest using a professional calibrator system which would almost certainly have done no good. I'd suggest you return the Thunderbolt display for refund and buy a different brand or wait until Apple releases a new generation of displays, whenever that happens.
Regards.

LCD display for graphic designer/photographer

My Mac Pro two 2.26 GHz Quad Core should arrive in a couple of days. I'm now in the process of choosing a 22"-24" LCD display monitor. As I am not attracted to the Apple 24" display's glossy surface, I've narrowed display choices down to these:
1) EIZO CG222W 22.2" Widescreen LCD
2) NEC MultiSync 2490WUXi 24.1" Widescreen LCD
Anyone using or know anything about either of these? I understand they are popular with graphic artists and photographers, but I am particularly interested in learning of any compatibility issues with the early 2009 Mac Pro/OS 10.5.6. NEC's support website notes possible compatibility issue between its 2490WUXi SpectraView II calibration software and OS 10.5.6.
If I chose the NEC model, could I use another calibration software/colorimeter with it instead? If not, then I would just go with the EIZO.

just got my two 26" NEC MultiSync LCD2690WUXi2 and hooked them up to a new nehalem mac pro with a radeon 4870. the monitors work perfectly. all i can say is wow. the color accuracy out of the box is great. the brightness uniformity is incredible. the blacks are really black and the whites are perfectly white. i've owned two 23" apple cinema displays and two 24" led cinema displays in the past, and these NECs look much better. very professional.
i do have two gripes with the 26" NEC MultiSync LCD2690WUXi2. its cased in some sort of plastic. the base is made from the same material. i'd rather have an aluminum casing and base like apple provides. the other grip is that there is a lot of flex where the actual panel attaches to the base. its a bit wobbly. this i don't like at all. they could have done something better with this. otherwise no other problems to report.
but all in all, the image on the screen is so good, that i won't complain anymore from this day forward. an absolutely stunning image on these screens. love em'!!

Introduction of LCD display

LCD display, known as LCD (Liquid Crystal Display), belongs to a flat panel display. Used for TV and computer screen.
【Introduction】
Liquid crystal display (LCD) used in digital watches and many portable computers. LCD display uses two pieces of polarized material, between them is the liquid crystal solution . Current through the liquid crystal will rearrange so that the light is not available through them. Thus, each crystal is as shutters, not only can allow light through but also can block it. Liquid crystal display (LCD) technology are now moving toward to light, thin, short, and small, he traditional CRT display which has a long history in computer peripheral products, display is also no exception.Under the title of easy to carry and transport, the tranditional display method such as CRT display and LED display boards, etc., are subject to too large or even giant power consumption and other factors, can not reach the user's actual needs. The liquid crystal display technology development is in line with the current trend of information products, no matter in right-angle display, low power consumption, small size, or zero radiation, etc., all can allow users to enjoy the best of the visual environment.

LED is just the method of backlighting. The display panel is still LCD. Typical LCD panels (including iMac and some other Apple LCDs) still use CCFL (Cold cathode fluorescent lamp) for backlighting. The unibody MacBooks (and the LED Cinema Display) have moved on use LEDs.
So they are still LCD displays in either case. The only difference is the source of the backlighting. LEDs are supposed to provide more even lighting, if designed right. They also do not fade in brightness over time and use, like CCFLs, and are more energy efficient.

Will there ever be an LED 30" cinema display ?

Bored of my 30" LCD now, will there ever be an LED 30" cinema display ?

Confirming that there will absolutely not be any hi DPI updates for InDesign 8 (CS6) either for Mac or Windows. As Peter indicated, this support was part of a massive code rewrite that went into InDesign 9 (CC) to support 64-bit versions of InDesign and the transition from the so-called Carbon to Cocoa programming frameworks on MacOS.

MEGA 865 - no LCD display

My LCD display has suddenly stopoped working after a few days. It worked when I first plugged it in fine. Have tried the unplugging for 2 minutes trick, but it did not solve it. What do I try next? Can someone please help?
Pete

I've had this problem many times and I want to share the tip on how to make your LCD work again. Pull it out and plug it back in but slowly. What I mean is when you plug the power cord in, the connector on the cord just barely touch the connector on your Mega 865 and you will see the Hifi LED lights up. If it doesn't work, do it again by moving it around. Suddenly you will see your LCD back on again

Creative MP3 Player (Microphoto) Blank LCD Display Scr

[size="">Hi, The LCD Display Screen on the Creative MP3 Player is blank. The blue background light will come on but nothing on the screen. I saw that it was suggested to update the firmware, however, I have no idea how to do that. If someone can explain to me how to do that I will try it. Or maybe you can suggest something else that I can do. I already tried several things suggested on your website, like removing the battery and installing it again, etc. I would appreciate it if someone would help me. Thanks!

[size="">Good Morning,[size="">I tried the firmware upgrade, however, the screen is still blank. Should I have removed the batter and re-install it again? I tried calling support, however if my product is not in warranty it really doesn't give me that many options or refers me to anyone. Is there a telephone number in particular I should call. Thank you for your advise though, I appreciate it!? Have a

Problem with LCD display on 17" iMac G4

The LCD display on my iMac went wacky on me yesterday. It's as though one of the three primary colors no longer works. The screen has a green tinge to it, and anything that's supposed to be black shows up as green. I've reset everything, run the Hardware Tools diagnostics (no problems found), and changed resloutions, monitor depth, and brightness levels many times. No luck. The screen is readable although very ugly.
Obviously I can take it to an Apple Store, but does anyone have any idea what it might be? I've searched the net and the forums and can't find anything close, but I know I can't be the only one to experience this problem. I called a mac repair shop a few minutes ago, and they said that the logic board would need to be replaced. I just can't believe that because nothing else is a problem.
Please help. Thanks.
17" iMac G4 1Ghz Mac OS X (10.4.6)

I "fixed" the problem a few days ago. Digging around here in the forums, I found another thread that gave explicit instructions on how to open the iMac and re-seat the connections. Here is the link (http://discussions.apple.com/thread.jspa?threadID=196785&start=30&tstart=30). It's a post from Androcles made on 3/26/06.
Just as he indicates, when I did this I found nothing to be loose at all, however upon putting it all back together, on the 2nd re-boot all was back to normal and still is. It's amazing how clear and crisp the screen is after suffering through the green hue for a few weeks...
Good luck, and feel free to ask me for help if necessary.

Mega865 - No LCD Display

I' have the problem describe in the "Important Threads - Things to know before (and after) building a Mega 865".
When I receive my Mega865, i tried it without processor and it seams works well. So I assemble it to work in PC mode and all is OK too.
Because I had the sound problem (no device found), I read the "Important Threads" and so I realise that my LCD display was not working too (i only use PC mode at this time).
I don't know if the two problems are in connection.
The sound problem disapear but I have still no Front Lcd Display.
I flashed the bios with the new version (1.3) and verified all the connectors that i could see.
What can I do more ? Is my MoBO dead ?
Thanks for your answer.
Vincent

i think it might have something to do with the proximity sensor and that sensor disables the phone functions when in call mode so that you do not accidentally press any other buttons.i think that it disables the touch screen when you put it close to your face. once you hand up the phone, it returns to normal operations right?

I have a slight crack in my mac book pro screen it is just on the top of the screen and the LCD display is working fine. i was wondering how much it would cost to fix it/ replace it.

Apple LED 24" Cinema Display audio problem under 10.6.8 (with post fix)

Hi all,
I'm using an Apple LED 24" Cinema Display with a 2010 MBP 15" and had been using 10.6.8 without problem. After installing the post-fix I now get static noice on (clipping?) when music contains lots of base. If I switch the output to my MBP's built-in speakers then the audio is fine.
Is there any way to un-install the 10.6.8 post-fix?
Thanks,
Yanik

Solved the issue. This issue coming up after installing the 10.6.8 supplemental update was just a considence. I ended up tracing the issue back to my Atlona AT-MDP21 Mini-DisplayPort KVM switch and after fiddling with cables the issue went away.

About monitors and LCD displays

I want give you some directrices about the display sub system.
Like you all know there are CRT monitors and LCD displays.
CRT
CRT monitors are based upon electron beams hitting Electroluminescent phosphorus. In these monitors the most important parameters are:
1) Dot pitch
2) Refresh rate
Dot pitch is the size of a single phosphorus point, smaller is better. Typical values range between 0.24 and 0.25. Beware with monitors having a not constant dot pitch, there are monitors with dot pitch of 0.24 at center of screen and 0.25 at the borders. I recommend monitors with constant dot pitch size across all screen.
Refresh rate is the number of times a single electron beam travels across the screen drawing a single frame (from left to right and top to bottom) each second. It is measured in Herz (Hz). Bigger is better. Typical values range between 60 Hz and 120 Hz and the value depends upon resolution, more resolution goes to less possible refresh rate. If you are going to play games with shutter glasses, make sure your monitor is capable of 120 Hz minimun at the playing resolution. In 3D Stereo, each full 3D frame must be drawn 60 times/second (60 Hz) but a 3D frame is a single right eye frame and a single left eye frame, 60 Hz for left frame and 60 Hz for right frame are the full 120 Hz. If you CRT is not capable of these 120 Hz your eyes will suffer fatigue / strain and you would have a great headache after prolonged time periods.
LCD
A LCD display do not uses a electron beam to excite phosphorus and generate colored points, instead this it uses a grille and a special lamp. Instead drawing a frame line at line from top to bottom and left to right, it renders the frame in a step only and continuously, these displays are flat for this, there is no necesity for high voltage and magnetic fileds to move the electron beam. In these displays these are the more important parameters:
1) Dot pitch
2) Response time
3) Number of colors (color space)
Dot pitch is the same as with CRTs
Reponse time is the time it gets going from pure white to pure black. Less is better. It is measured in miliseconds. Good typical values range about 16 ms. If you are going to use the LCD to play games, response time is the more important parameter at all.
Number of colors are the simultaneus colors in screen. It have a inverse relationship with response time. It is measured in million of colors or bits. 24 bits of color depth are 16.7 million of colors. Typical values range agout 16 / 16.7 millions. Greater is better. LCDs with 16 ms response time have, usually, 16.5 millions of colors.
Somethimes, the manufacturer will provide you drivers (setup or inf files) for your operating system. I recomend install this drivers. Don't panic if there are no drivers for your display device, Windows, probably, will find the suitable driver for your brand and model.
If you have a CRT and you are stuck at 60~85 Hz you will need the right driver because Windows would not have found a suitable driver from its drivers base and it chose a standard monitor driver.
If you have a LCD and you are stuck at 60 Hz, all is fine, as i have told you yet, LCD displays paint the screen continuously, you will not appreciate any flicker at 60 Hz in these devices. You can check this if you have a digital camera, make a photo of a CRT with a shutter of <monitor refresh rate> * 1.5. You will see a partially drawn picture. If you take a photo of a LCD with the same shutter rules you will get a full picture. With LCD you will get full pictures always, independently of the shutter.
I hope al this info will be helpful to you.

I have found a very interesting link on the Anandtech Web site about LCDs, it is a old one but i think it will be useful.

Mac Mini LCD Display - finally got it working but....

Hello,
I've posted on here many times about using the mac mini with my LCD display. The display runs at 60hz and a 640 x 480 resolution. For about four weeks, the mac mini would not connect to my screen. I installed display config x and had something of a result. By loading the mac mini up with my old pc monitor plugged in and then switching the vga plug once the mini was loaded, I managed to get a picture!
Just when I thought my troubles were over, I realised that when the mini went to sleep, if I woke it up I had exactly the same problem. I would have to plus it into my pc monitor, wake it up then switch it with my LCD VGA cable.
Is there anyway round having to do this every time I want to use my mini?
Thanks
Mark

Check out the manual for "Autoload" -- that's the name of the song file that's automatically loaded each time you start Logic or create a new file. You may want to look at some of the Peachpit books for walking you through creating this file to match your studio and workflow.
Use Caps Lock to bring up a little keyboard on the screen that you can play with your computer keyboard.
To change a track's icon, make sure you can see the track's info in the Arrange window. First select the track you want to work with. Pressing P toggles the properties column on the left. You may have to open up one of the areas using the little drop-down triangle thing, but you'll see an icon for the track in the properties area. Click and hold it to bring up a list of icons. You can create your own icons in the png format. Read the manual if you want to add your own images to Logic's standard icons.

Will my LED 27 Cinema Display work with the new Mac Pro?

Will my LED 27 Cinema Display work with the new Mac Pro?

Mini DisplayPort (like 27" LED Cinema Display) is a direct subset of ThunderBolt (like Mac pro late 2013). It plugs right in and the display portion "just works", no adapters required.
