Mini display color bleeds

New mac mini with Mountain lion shows color bleeding on display - that is, text which should be black and white shows random colors on some letters. Same monitor used with older mini was fine. Could it be the graphics card? or the hdmi to hdmi connector?? Older mini used hdmi to vga adapter.

Create a new user, log out your current user and log in as the new. It colors are displayed correctly, then I guess you could go into the other user's library and delete the offending file.

HT1338 Mac mini display color setting problem

On my Mac mini the color displat settings are gone pinkish. I checked the HDMI cable to the LCD TV and it is okay. Help me to resolve the problem

To check if this is something in your current user account, Log Out from the Apple menu, to get to the login screen. Does the screen look "pinkish" at the login screen? If it does, there is a problem related to the overall system, or hardware.
If things look normal at the login screen, then the problem is probably related to a setting in your user account. Log in to your normal user account. One place to check is System Preferences Universal Access pane. On the Seeing tab, look at the Enhance contrast setting. Make sure it is set to Normal.

Mac mini display color changed. How do I get it back to normal?

I picked up my keyboard to remove dust and dirt, and I must have pressed some button or two, because now the colors in my display are horribly wrong.
I opened Library/ColorSync
and then Profile First Aid.
I verified and repaired and got this message:
"Library/ColorSync/Profiles/EW-sRGB
Tag 'desc': Tag size not correct. Could not be fixed."
What do I need to do to get my colors back to normal?!?!?

Thunderbolt mini display port cable to HDMI not registering

I recently purchased a 6" mini display port to HDMI Cable. When I connected my macbook to my HDMI on my TV the macbook pro does not show the screen as a display option. When I go to system prefrences and under displays the tv is not showing up under arrangements. The only options I have is Display and color, I do not have an arrangement option. My TV doesn't seem to see the computer either.
I have a thunderbolt port but the cable says it's for a mini display port but works with Thunderbolt, I've used similar mini display cables before with the thunderbolt with no issues. I'm on an early 2011 macbook pro running 10.6.8
Thanks!

You may have better luck getting a response/answer if you post the question in the MacBook Pro discussion here.

Apple Mini Display Port NOT working at resolutions over 1600X1200!

Problem:
Apple Mini Display Port does NOT work at resolutions over 1600X1200 on NON Apple Cinema Displays.
That means if you own any other brand of monitor such as NEC, Lacie, etc. you will NOT get native resolution on your 24 inch monitor as it is stuck at a maximum resolution of 1600X1200.
This story was mentioned on "Macbreak Weekly" show 4-14-2009. I have since checked with a few people and it would indeed seem to be true at this point.
I REALLY hope a solution from Apple comes soon and this is not some new policy of theirs. If so, it may be the last Mac Pro I will or can ever own. The reason is I do a lot of 3D work with C4D, Vue, Modo and Photoshop CS4 so I MUST have a monitor like the high-end ones from Lacie that have 100% color gamut and Adobe RGB. I can NOT be tied down to an Apple Cinema display due to that work. At this time, it seems this means I would only get 1600X1200 resolution on that 24 inch monitor.
Has anyone else confirmed this too and if so what the heck is Apple thinking or better still going to do about it? I LOVE my Mac Pro but if they start forcing displays on us then I won't be buying another Mac, it's just that simple.

Thanks, but I think two things may be different in that setup.
1. If I understood correctly, it's a first gen without a "Mini Display Port" and
2. It was a laptop not a Mac Pro with a video card.
I think it has specifically to do with either one or both of the above combos. In particular I think it's the video card they are putting in them.
I am not sure if a new 2009 Apple laptop with a Mini Display Port connected to a NON Apple display would have an issue or work like yours does now. It would be interesting to get to the bottom of this for sure because it REALLY hurts people like myself that are into 3D design.
I will try to get back on this once I continue to find out more details.

MacBook Pro - connect to TV via HDMI Mini Display adaptor

Can't connect macbook pro to my TV and view/listen to what's on my mac on the tv. I am using an HDMI cable from the tv to a mini display port HDMI adaptor. When I go to system preference, display it doesn't have an Arrangement tab to mirror. It only gives me tabs for Display and Color. Any help would b appreciated.

Hello pdr4d,
Based on your post it seems you are unable to get video on an external display. The following article may help you find a solution:
Apple computers: Troubleshooting issues with video on internal or external displays - Apple Support
Check connections
When using an external display be sure to check the following:
If you're using an Apple notebook, confirm the AC power cable or adapter is securely connected to the computer and the cable providing power to the display is also secure. It is always good to have your notebook connected to AC power when an external display is in use.
Confirm display adapters are fully seated in their respective connections and that they are supported models and for the computer and display. Refer to these articles to assist you with adapter compatibility and further configuration information:
Monitor and Display Adapter Table
About Mini DisplayPort to HDMI adapters
Apple Mini DisplayPort adapters: Frequently asked questions (FAQ)
Thunderbolt ports and displays: Frequently asked questions (FAQ)
Remove all display cable extenders, KVM switches, or other like devices and retest to determine if the issue is resolved.
Try unplugging the video adapter or cable and then plug it back in.
If more than one video adapter is in use (or "daisy-chained"), troubleshoot by using only one adapter.
Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).
Reset the system
You can reset the Mac's parameter RAM and SMC.
Thank you for contributing to Apple Support Communities.

U430 dull display colors

I got a new u430 touch. Everything seems great except the display. I get the feeling that the colors are washed out and no black levels. Tried a simple test http://www.lagom.nl/lcd-test/black.php
Unable to see the first 5 black squares. Poor contrast. These are visible in my 5 yr old dell vostro. Is a dull display and lack of vivid colors on u430 normal? Pretty disappointed since display colors are very important for me. Surprised how even a latest display is not vivid. Can someone advise what my options are? Does only U430 suffer from this problem? Are there any calibrations that can fix this to some extent? Are there any lenovo laptops with good display under $600

Did you find a solution? I've got mine rigged to a really old monitor - shamefully the display on that is miles better than the U430 - feels totally washed out!!

Mini-Display or DVI

I just bought a new Mac Pro and I have a samsung SyncMaster 2253bw display that uses DVI, I have it plugged into the DVI port on the back of the tower. Is that what I should be using OR should I be using the mini-display port to DVI adapter? Sorry if that's a dumb question that has already been answered, but I did search and couldn't find anything conclusive in the Mac Pro forums. Thanks!

Thanks for that link! That brings up an interesting question though from what I read. If I go into my "about this system" window and click on graphics/display my syncmaster says that my pixel depth is 32-bit color, so is it safe to assume that what I see on-screen is in 32-bit color? I ask because I am a serious photographer and color correction is very important. I also have never had a dvi and two other mini display ports. I have always had a macbook pro with just a dvi out.
Thanks for your help!

Reason for Mini-Display?

Why does Apple use mini-display ports and not straight HDMI? I mean PC users just hook up their PCs to any TV via HDMI and they're ready to go, while we need speakers in order to get sound.
Im an Apple loyal fan by the way, Its just that people ask and I don't know what to say!
Is there a functional benefit or something?
First I thought VGA ports are big and ugly, but HDMI is really thin and beautiful.

In addition, HDMI is basically for TVs and DisplayPort is designed for computers. Macs are computers. Apple assumes the primary use of the video port would be to extend screen space with another computer monitor, like I used to do before I bought a desktop. The reason the Mac mini gets HDMI is because it's used very widely as a media center connected to a TV. Apple probably noticed that a high percentage of mini buyers also buy the HDMI cable, compared to other Mac buyers.
There are definite technical reasons for a computer to have DisplayPort instead of HDMI. You can do a web search on the topic, here is an excerpt from one article I found:
HDMI is based on legacy CRT raster-scan architecture. DisplayPort is designed for modern flat-panel displays and PC chipsets. DisplayPort has a micro-packet architecture with low voltage signaling that more easily enables networked displays. In the future, DisplayPort will also allow daisy chaining displays at full graphics performance, including 3D. and content protection. Today's USB-based daisy-chaining solutions do not support high performance 3D graphics or protected content.
HDMI has rules for how to implement and use the technology. Business and enterprise customers may not want to implement all of the consumer electronics features that are required in HDMI products. In contrast, DisplayPort is the display equivalent of Ethernet....anyone can implement it in any type of application. A VESA compliance program ensures interoperability for products featuring the "DisplayPort Certified" logo.
DisplayPort supports higher performance as a standard feature-every 6-foot cable supports 10.8 Gbps. With HDMI, high performance is optional and comes at a significant cost premium. DisplayPort has better support for projectors and enables cool ultra-thin monitors. It supports native fiber optic cable and offers latching connectors, features that are missing from HDMI. Down the road, DisplayPort will allow multi-function monitors with a single cable delivering display, audio, and USB connectivity. It will also support multiple monitors on a single connector.
I also think I read that HDMI requires that the manufacturer implement certain DRM/copy protection tech as part of its consumer electronics purpose. That is why the excerpt above refers to "content protection."
For those in the design/photo fields there is this bit of obscurity, which is that DisplayPort can support more than 8 bits of color per channel in the video signal. I am not sure if HDMI can do that.

Mini display is shutting down computer.

I've been using a mini display to HDMI cord for awhile and nothing has been wrong with it until the other day. When I plugged the mini display into the port on my 13 inch MacBook Pro, it just shut down. Does anyone know why?

This isn't a new RAM issue as I haven't installed any. When I re-installed all of the software from the ground up, I did an erase and install, so the whole thing should have been basically wiped before I installed the Mac software.

2008 macbook pro 15" (Santa Rosa) weird display color and vertical lines

I have the 2008 macbook pro 15" (Santa Rosa). After my upgrade to mac os x lion (10.8.2), I noticed that periodically the screen either turns to weird display color and have horizontal lines on screen. This happens mostly during start up and lasts for about a min or two. Does this happen because of a faulty graphics card? I have NVIDIA GeForce 8600M GT 256 MB card on this macbook pro. Please advice

Nope - it sounds as if you've GPU issues and the discrete GPU is soldered onto the logic board. take your new machine into your local Apple Store for a replacement. Don't wait too long!

How do go back to my default display color settings? Just bought Spyder 3

Hello out there in Genius land...
I just purchased Spyder 3 Pro to calibrate my display monitor, but in order to do this correctly, I need to go back to my default color display settings.
I have manually calibrated my display several times in the past in the advanced mode, so I am familiar with this process, but I am unable to figure out how to go back to the default. Can't find a default option in the color settings tab.
Any assistance in this matter would be greatly appreciated.
Thanks,
Anneita

Thank you for your quick response.
I just checked mine since I never changed it. It shows I have two default color >displays - Color LCD.
When I select either one, the "Delete Profile" button is grayed out. This would >indicate to me that you should also still have your "default" color profile >showing.
Hmmmm....
Good point about the grayed out "Delete Profile" button. I went back into my "Color" tab to check it out, and I have 4 different profiles listed:
- 12-30-10
- 7/29/08
- Color LCD
- Color NTSC (19530 Calibrated
When I click on each of them, they show a totally different display color.
The only one that the "Delete Profile" button is not grayed out is 12-30-10, which I made on that date. The other 3 delete buttons are grayed out. But I am thinking that my actual default may be the one that says "Color LCD" like yours.
Is that safe to assume? What do you think?
Thanks,
Anneita

Im the photographer... the display color change when i upgrade to SL..

I m a photographer, after i upgraded to SL, all my black and white photo are yellowish. The black are not total black and the white are not total white like in os x 10.5.x. Are any others photographer upgrade their os and face this problem too?

Check that the correct profile is selected for your display (in Sys. Prefs. -> Display -> Color)
After installing SL mine was not set to the correct profile. I fixed it, and it has remained set to the correct one since.

Mac Mini display randomly blanks for a few seconds....

The Mac Mini that I bought a few weeks ago randomly goes blank for a couple of seconds at a time (black screen). There is no regular interval between occurrences -- sometimes it can go an hour or more between "spasms," other times it may blank two or three times within a ten minute span. Occasionally, it comes back to a snowy screen, that lasts for another couple of seconds, before returning to normal.
I have searched online, and have seen this mentioned in reference to the nVidia 9400, which is the graphics adapter in this model Mac Mini. I have tried both the mini-DVI to DVI adapter, as well as the mini-display port to DVI adapter, as was suggested in one post. The occurrences are less frequent with the mini-display port to DVI adapter, but they still occur with an unacceptable frequency (if occurring at all is acceptable). I have also tried three different flat-panel monitors (Samsung, LG, and Acer), with the same results.
Has anyone else experienced this problem? Does anyone know of a solution, other than returning the computer?
Thanks.

Yes. This is exactly the issue I'm having. I'm both sad, and happy I'm not alone!
I added this message in another post before I found this one.
"I'm using a 27 inch ASUS LCD over DVI from the Mac Mini. It doesn't matter if I use a mini display port to DVI adapter or an HDMI to DVI adapter, the screen will randomly "Flicker" the image into a reversed color image thats slid to one side a bit. Other times it will go black for half a second randomly. And then, after a group of close together "Flickers" it will on occasion go into the "Colored static" issue like you are experiencing.
I can either power cycle the monitor or the Mac to solve the issue. I assume this solves the issue because it forces the Mac to handshake with the DVI connection again, and temporarily resolves it. Some times it will only "Flicker" one or two times a day, other times it will do it in cascades until it goes into the "Colored noise" problem again, which I have only seen a half dozen times in the last few weeks.
The Mac Mini did not do this initially, so I'm thinking it's from one of the boot camp updates? I hope it is, because that means it can be fixed with a patch."
I'll drop apple some feedback. Thanks for the link!

HT201177 How to connect my MBP 13" (Mid-2012) to a projector/LED TV using a mini-display port VGA adapter (CAPDASE)

Hello Sirs, I'm having a hard time connecting my MBP 13" (mid-2012) to my projector using my mini-display-VGA out adapter. But when I switch to Windows 7 (via bootcamp), it can easily be connected... Please help me with this problem. Thanks

Try connecting the Minidvi to the VGA and connect it all together, first try turning ing on the MBP, then connecting dvi to the the projector. Make sure your projector input is set for VGA. If noo joy invert the affored mentioned proceedure. You should see your image if not, try going to system preferences>displays, click display. Try readjusting the resolutions in display. reboot monitor.
