LCD/LED Monitor Problems

I have just purchased a new 2010 Mac Mini and an LG E2240S LCD - LED backlit monitor. I have this connected using a Mini DisplayPort > VGA adapter.
I have resolution set at 1920x1080 at 50Hz which seems the best setting.
The problem is everything seems very grainy and text especially looks very sharp and jagged around the edges.
Any ideas what would cause this?

The monitor should have a function that is sometimes called tuning. See if that improves the picture.

Your Suggestions on Adding External LCD / LED Monitors to MacBook Pro?

My current work station is a PowerPC G4 Dual 867Mhz with dual 19" CRT displays. I use this for design work (Adobe Illustrator); photo restoration (Photoshop); & online sales.
I was down to my last two CRT monitors, and wanted to perhaps start porting some of the graphic intense work to a faster computer so I bought this MacBook Pro:
http://support.apple.com/kb/SP499
I have not actually had a chance to use the MacBook Pro - it and all the accessories are still sealed - I couldn't afford the down time to set it up.
I am wanting to add a external monitor to the MacBook Pro that would be suitable for detailed design work with accurate color, true blacks, and the ability to be correctly calibrated. Since I may be still doing work on the G4 with software that will not run on the MacBook Pro I'd like to perhaps buy 3 matching monitors , 2 to replace my crt units and 1 for the MacBook, so that I can closely match the design output between the G4 and MacBook Pro.
I briefly tried a inexpensive LCD TV with a PC hookup on the G4 to get some idea of how an lcd would look. The LCD TV had a native resolution of 1440 X 960, which is a 3:2 aspect ratio, but that resulted in designs elements being distorted (i.e., squares look like rectangles). In 4:3 mode the TV did not distort the design elements, but the picture was not crisp / sharp and appeared soft. From what I've read this is because the lcd, unlike a crt, can't correctly emulate resolutions other than the native resolution built into the screen (i.e., its software guesswork). I also did not like the fact than in 4:3 mode it left black areas on the right and left edges of the screen.
I typically work in a 4:3 aspect ratio with a resolution of 1024 X 768, but a higher resolution of say 1600 X 1200 would be o.k. So what are your suggestions as to finding a lcd / led monitor that has a 4:3 aspect ratio? So far I've found limited information on what appear to be old monitors - there's one on Dell's site; for example, that says it has 1600 x 1200 native resolution, but a review also says its the same monitor they've been making for 5 years (besides I don't think I'd like the idea of hooking a Dell into my Mac). Found a few references to Lacie and NEC.
I really don't understand the monitor manufacturers, including Apple, that claim their monitors are for design work, when they don't offer native a 4:3 aspect ratio. How exactly am I to complete designs when circles are ovals and squares are rectangles?

"Take a flash drive with some representative PDF files saved from Illustrator to your nearest Apple Store or Apple reseller and ask for a demonstration using one of Apple's beautiful 27" 2560 x 1600 monitors. It would replace both of your 1024 x 768 CRTs with lots of additional desktop real estate to spare."
1. Well, actually no since I do not have fixed 1024 x 768 crts since crts do not have fixed resolutions. I can easily set each monitor to a variety of other resolutions including 1600 x 1200. Actually the Apple display would be a step down in total working area if I used the largest common resolution of 1792 x 1344 and certainly not worth the extra cost for the space gained if working at 1600 x 1200.
2. Unfortunately the display requires 10.6, which does not work on a G4 Dual 867Mhz. It would not even work on my MacBook Pro that I've not had a chance to use yet as it comes with 10.5. Also, 10.6 drops supports for PowerPC emulation so that means buying hundreds of dollars in new software. I use Apples only, but one thing I hate about the company is what many perceive is their "elitist attitude" toward their users - do they really think most people in the real world have so much money that in order to use Apple's new 27" display that they have to go out and spend more than the display costs on updating their computer and software. I am not a zombie fanboy willing to buy anything just because it has Apple on it.
3. Like most people I do not live by an Apple store or a Apple reseller, even the local Best Buy does not carry Apple computers in their store because the retail space does not justify the resulting sales (not that I would buy anything there anyway as they are over priced). I am really not interested in driving several hundred miles to the nearest store.
4. For a $1,000 I expect a monitor to offer a native 4:3 (1600 x 1200) aspect ratio - certainly Apple knows that this is the preferred working environment of many CAD and graphic users but they chose not to offer this in the display, thus the Apple display is really seems geared toward pop corn munching movie watching consumers.
5. This display is not actually made by Apple, its probably LG or one of their other suppliers.

27 LED Monitor Thunderbolt sound problems

I have a Mac Pro without thunderbolt, i bought a 27 inch and just bought an adapter to get it working. Its been working fine for months. I recently upgraded to 10.8.2 on a new drive and everything just went to ****. (one of the reasons i didnt want to upgrade)
First, i was having problems with my main account. Not able to open calendar because i didnt have permission (i did have an admin account), the problems calibrating my monitor (said that it could not find the profile) then problems with Terminal saying that i didnt have permission.
So i said **** it, and juts created a new account and it pretty much fixed everything and deleted the old one.
Now, i left my computer on and went out to take some pictures, when i get back and try to import and listen to music, i find out that the music/sound is coming out of my headphones. (i didnt changed it). Asked everyone at my house to see who touched my pride and joy, but no one did.
When ever i try to select Display out, it automatically changes back to headphones. Everything working but the sound. Restarted the computer and nothing. When i unplug the USB from computer it will crash it and restart. Left the computer off and USB unplugged for 15 seconds and still nothing. Tried other stuff that i read online and still nothing.
I did find out that a lot of people are having problems with LED monitors and Lion.
This is a clean install from less than 1 week, from 10.6.8 to 10.8.2 so i know that its not other software interfering.
Hope someone have an idea what the **** is going on with Moutain Lion

well, OSX 10.8.2 is freakin stupid. The Display Audio just started working all on it own. I had it on System preferences window, when i came back Display Audio was selected and i can play back audio.
If any one has an idea on why this problem is happening and how to prevent/fix, please let me know.
Thx

LED monitor strange pixel problem

So I got an LED monitor for Christmas. Today I noticed on some websites, some pixels are flashing different colours on some images. It's not those specific pixels though, if I scroll so that location is on another pixel, that pixel does it as well.
Is this a stuck pixel issue? Is there software I can run to help sort the issue out?

Professional Calibration for the Powerbook Pro with LED Monitor

This is what I have discovered: The new LED monitor/screen is a better technology for graphics pros because it's brighter, doesn't need to warm up like CRT and LCD, and it's more efficient. I have also discovered that the current Powerbook Pro with LED is not possible to calibrate with a spyder-type device because the computer itself doesn't allow the user to control overall R G and B levels at all...so as to achieve a prcise initial white point setup. Once RGB levels are balanced, only then can a spyder with it's assoc software continue it's recordings with precision. Other problems exist: Apparently the graphics cards in the Powerbook Pro (I have the newest machine, bought Nov 2008, with LED screen) are not able to permit any software (like Monaco Optix) from adjusting the brightness or color levels. As well, to my knowledge, there are not currently any spyders with software which offers LED as an option initially. I tried setting it to LED and LCD with my LED monitor, just to see the difference....and there was a huge one...so it's futile even to use the spyder if the software hasn't been developed with the LED screens in mind.
*What I did was this: I calibrated my LaCie electronBlueIV 22" professional monitor with the sypder...using Monaco Optix and it's XR spyder. Once that was established, I opened a photoshop sample image which has a blue sky, green pine trees, green/yellow grass, a red boat and some white snowcapped peaks. Made a duplicate of it....and placed one copy on the LaCie and the other on my powerbook's monitor just below (I'm running 2 monitors at the same time). Then I went through the "professional" mode of Apple's calibrator. Unfortunately it's not an exact science as one might think. No, you can't work it back and forth until the colors match because of certain ways in which Apple has made their calibrator function. For example, you only set the degrees kelvin at the end...which totally changes all the color levels you have done up until that point....it's complicated to explain, but if you go through it once, you will understand what I'm talking about. Anyhow, so what I did was go through it all the way.....then right before saving the profile....I would go back again (you can go backwards and forwards and it keeps the adjustments you've made already...luckily) and tweak these various adjustments...all the while...*keeping an eye on my 2 images...trying to nudge my powerbook colors/brightness/contrast as close as possible to my calibrated LaCie. Finally, I used the final adjustment (D50/5500/D65 etc....) to put some more warmth into the powerbook's monitor which seems to be much too cold if you only use the calibrator and have no other monitor for reference. I set mine around 5,200......when normally I would be at 5,500 with any other monitor.
It seems I did get my LED monitor pretty close to the values of my calibrated LaCie....as close as I could visually...considering, to my knowledge, there is no current device/software that will calibrate this LED monitor. We're waiting!!
*Just a friendly note to Apple*
Dear Apple,
For years you are aware that it is the creative professionals (photographers, graphic designers, visual artists, printers, architects, etc...) who have been the loyal backbone of your small market share. We have been the ones investing and reinvesting in Apple computers and peripherals since the beginning...before the ipod and the iphone when all of the other yahoos jumped onboard. Also please understand...we love the new generation of powerbooks but we're tired of having to drag around an extra monitor to insure correct colors for printing/color-matching. I'm a professional photographer who is always traveling internationally...and away from my calibrated monitor in my office. Yet, many times I have to retouch on the go and get the images to my clients..and it's just not possible to work on a calibrated monitor at these moments. Yet my work is precise work and the color values are critical to my clients in the world of fashion and beauty.
Realizing this point.....knowing your core clients are concerned with critical color values....why is it that you continue to create portables with absolutely no precise color controls?!!!!!!!! Would it be so difficult to add a utility which allows the user to digitally control RGB levels, contrast, and brightness (withe their associated numeric levels, (for example: brightness=78.3%.) As well, your own calibration assistant..."professional" mode??? HARDLY. Why not build onto this model with another mode...let's call it "super professional" mode (lol) which allows us to access overall RG&B....as well as brightness and even contrast???
That's what I know at this stage. If anyone has any advice which adds to what I have said, or maybe someone can educate me with a more accurate way to calibrate my monitor....I'm all ears...and I'm sure I'm not alone in this quagmire.
S,
Lawrence

I've had the same concerns about the lack of any monitor controls (unless there's something I'm missing), but afraid I don't have any answers myself yet. Just wanted to ask do you mean "Powerbook Pro" or are you talking about a MacbookPro?

MBP 15' 2011 Mini display port to LED monitor/TV resolution issue

Hello,
I have just bought a Mini Display - VGA adaptor which I am plugging to a Samsung 23' LED monitor via a VGA/DVI adaptor. I manage to get a clone view but unfortunately, the maximum resolution offered is 1650x1050 when my Samsung LED monitor has resolution of 1920x1080. Therefore, part of the screen remains black.
... also, when I plug the Mini display port to VGA to my Philips 47' VGA port, I got a message that there must be a problem with the connection and again, maximum resolution offered if 1440x10.. and therefore 20% of my TV screen space remains black.
At last, when I launch Windows7 via bootcamp, this is even wost : when I select the max resolution (1440x10..), the pictures remains freezed on my TV and I can't even move the mouse (while the mouse is moving on the MBP screen...). Only coming back to a very small resolution 800x600 or so will enable me to get control of the win7 desktop on my TV...
Thank you in advance for your help
Greg

If you are using the monitor in Mirrored mode, its resolution setting will always be exactly the same as that of the built-in display. I presume you have the high-res 15" MBP display, with a native resolution of 1680 x 1050. If that's true, I suspect your monitor is indeed in Mirrored mode, and that's why you can't set the monitor to its native 1920 x 1080 resolution. If you press Command+F1 to toggle the mnitor into Extended Desktop mode, you'll be able to set its resolution independently of the built-in display. Or if you use only the external monitor, with the MBP display closed, you'll be able to set the monitor's resolution to whatever it supports.

Stacking one video adapter on top of another is usually a recipe for trouble. It's always best to keep things as simple as possible. Use one adapter that gets you from mini-Displayport to whatever input you want to use on the TV or monitor.

I have a 2009 17" macbook pro .... how do I connect two 24" Viewsonic VX2450wm-LED monitors.

I purchased two 24" Viewsonic VX2450wm-LED monitors to connect to my 2009 17" macbook pro.
The monitor inputs is DVI. Since the plugs do not match up...an oversite on my part when buying the monitors online, I am hoping to run these 2 monitors from mini displayport to DVI. However, 2 external monitors requires a hub like the DualHead2Go DP Edition
However! This device has many poor reviews on Amazon and I am concerned about spending the money and wasting the time on a device when there may be a better option.
At this point I dont plan on using the macbook screen while using the twin 24" screens.
The answer to this problem is not an easy one to solve and the answeres to my questions I am finding are bringing up new concerns...for example, learning that the Matrox above mentions that Hz compatability which i had never previously though of, may have been a problem to consider...depending on the monitor...however, i think im good here.
Can someone baby step me through the process and exactly what components I need to get these 2 External monitors working properly via my macbook pro?
Note: Please do not be an arrogant computer d!k. I have already had 1 person act like a smart @ss when all I need is a real answer...not someone else Googling a 10 second easy answer and responding with sarcasm...I am quite familiar with a Boolean search...thanks but I am looking for someone with EXPERIENCE...not a search engine
*Would it be easier or cheaper for me to return these moitors and get different monitors with different plugs?
I appreciation all the input and assistance anyone can provide...I'm pretty new to the mac world.
BTW.
The system will be used for the Adobe CS5 Suite (mostly Illustrator and Photoshop), Pro Tools 10, Serato SL3, Video Editing (mostly iMovie) and browsing.

Hey drexfarrakhan,
Thanks for the question. For video, you can use a Mini DisplayPort to HDMI cable or adapter. Our online store has a few offerings:
Mini DisplayPort to HDMI - Apple Store (U.S.)
http://store.apple.com/us/search/Mini-DisplayPort-to-HDMI#!
However, your MacBook only supports video out via this connection:
About Mini DisplayPort to HDMI adapters
http://support.apple.com/kb/HT4241
So you’ll need an external stereo or speakers to output the sound to, using the headphone out port and a 3.5mm cable (or adapter, if needed):

I have two LED monitors i would like to connect to my Mac Mini.

I have two LG LED monitors and i would like to run dual monitors on my mac mini. Im running into a problem because i cant find a way to utilize the HDMI port on the back of the mini. For my one working monitor i use the thunderbolt display and convert that to vga. Is there any way to run dual VGA monitors?? i have seen some HDMI to VGA cables online but im not sure if they work due to their negative reviews.

It would be better to use the DVI (digital) connections instead of the VGA (analog) ones.
Then you could use the supplied HDMI to DVI adapter and a DVI cable for one monitor and then Apple's Mini DisplayPort to DVI adapter for the other. > Mini DisplayPort to DVI Adapter - Apple Store (U.S.)

Powerbook with Syntax Olevia 23-inch LCD TV Monitor

Hi there,
I got a 23-inch LCD TV Monitor from Syntax Olevia and somehow it doenst work with my powerbook.
The thing is when I connected it to my windows laptop, it worked just fine, I should say perfectly instead. Then I tried it on my Powerbook 12-inch, the Mac recognized the display, there was a VGA display on but when I turned the display on, it says 'NO PC SIGNAL'. You know, I'm ****** !
I have been on the phone with Syntax Tech Support for an hour, then with Apple for another hour, they suggested me to do everything try to get it works, everything they could find, everything within thier knownledge.... COULDNT CHANGE ANYTHING!
So the last thing the Apple guy suggested me is post a topic question here, to see what everyone says and if somebody out there has got the same problem, please do reply so, even you got it worked or not, just reply so I can have some experience. It might be compatibility problem but I don't know, not with a monitor I would say.
So here the LCD name and brand:
- Olevia 23-inch LT23HVX by Syntax.
I would appreciate for any answer, I'm looking forward to it.
Thanks all
Powerbook G4 12' Mac OS X (10.4.5)

Hi,
I'm not familiar with that monitor, but its resolution might be higher than your PowerBook can handle. I have a first-generation 12-inch PowerBook, and it seems that it can't run any of the Apple Studio monitors currently being sold. If that monitor can display a resolution of 1024 x 768, try that, as your PowerBook can certainly handle that resolution. Another thing to try is to see if you can find a friend or coworker who has a similar PowerBook (or any other Mac), so you can try connecting the monitor to that machine to see if there is a similar problem. If no Mac can drive it, you would probably have a good excuse for returning the monitor.
Hope this helps,
Ken

LG 29EA93 29 inch Widescreen LED Monitor Lightroom Issue

When I use Lightroom with the LG 29EA93 29 inch Widescreen LED Monitor Lightroom 5 initially looks and works OK but when I try and make changes using develop I get a gray area where the image should be (see below). I have tried other resolutions and that made no difference. Other apps/programs work fine.
I tried my old monitor 1680x1050 and Lightroom 5 functions fine on that one.
Any suugestions would be appreciated.

Uninstalling the LG software will resolve this problem.

External LED monitor.

In India, which LED monitor works best with the Macbook air 11". I am looking at Samsung/LG/Viewsonic 27" models. My concern is related to the device drivers. They all have drivers for Windows but not for Apple. Is that a problem?

That shouldn't be a problem, you don't have to install drivers for external monitors.

[Solved] another flickering monitor problem

Hi,
I hooked a new LED monitor to my laptop via a VGA cable but the sad
part is that the monitor flickers quite a bit. It's not a hardware
problem because I hooked the monitor to a windows box (using the same
VGA cable), and the monitor works perfectly well.
My laptop uses the video card ATI Radeon HD 3670. I'm currently using
the open source driver xf86-ati-video.
Here are a few things I've tried (many of them based from previous
posts) that I didn't have any success: to use the ATI's proprietary
driver (catalyst); to use xf86-ati-video-git; to disable KMS; to check
the output of xrandr (the preferred and the current mode match); and
to downgrade to older version of the xf86-ati-video. My archlinux box is
also upgraded.
I noticed the following patterns in my monitor flickering:
- it only happens with darker colors (no flicker when I open a white
page for instance).
- the flicker is not limited to X. The virtual consoles also flicker.
So I think that means that the cause of the flicker has nothing to
do with Xorg.
- the flicker is vertical.
- The flicker does not occur when I'm at the GRUB menu.
Any suggestion of how I can solve this problem is more than welcome!
Cheers,

I'm really glad you solved it :-)
If you want, you can boot a liveCD / liveUSB and see if it has problems with your VGA too. If it runs OK, the problems may be related to your Arch setup.
If you can get another monitor with a VGA connector you can test it too - maybe your laptop is just jealous of the new shiny monitor ;P
These are good ideas. I get the same flickering with the ubuntu live cd but I didn't try with the arch live cd yet. As to other monitors, I still get the same flickering when I use a different monitor with a VGA cable.
I think you're right: my laptop must be getting jealous :-)

New LED monitor is fuzzy!

I just bought a new AOS 23" LED monitor from best buy. Plugged it in, everything adjusted fine, but everything is slightly fuzzy. After looking closer I see everything on the screen, folders, dock items, background image, and curser are mirrored several times behind and to the right of the screen image. Resulting in the fuzzy look. I took a screenshot but it looks fine on this computer, hoping it's just a setting I can fix? Also I was going to get a dvi cable for it, I currently have it hooked up with vga, maybe that's the problem? Anyway... Thanks for any help!!!!

Hey,
Go to settings and displays and try reducing the hertz rate basically the rate that the Screen Refreshes and DVI is a digital signal VGA is analouge so DVI sould be better
