Stretched image MacBook Pro Retina to 720p TV

Whenever I connect my MacBook Pro Retina to my Panasonic HD Ready tv the entire image on the tv is stretched a bit vertically.
It's not the gravest of problems but it is pretty **** annoying when watching any kind of video. All the heads and everything is a tiny bit stretched and it just gives a generally distorted feel.
I've tried everything there is to try under Displays, like; mirroring, changing resolutions, scaling etc. but to no avail. Sometimes I can get a reasonable result when changing aspect ratios in VLC player but that doesn't always do the trick.
I tried connecting my MacBook to a Full HD tv once and the problem didn't seem to arise there, so I'm thinking it has to do with retina resolution clashing with 720p or something.
Can anyone help?

Hi.
Try adjusting the screen aspect ratio on the tv. This may sort it fir you.

HT5455 image persistence problem on Macbook Pro Retina 15"

Is it a faulty or normal behaviour if we see an image persistence after 5 minutes ( less than 15 minutes "Default setting of Energy Saver while using Power Adapter" to sleep/ turn off the display of Macbook Pro Retina 15 inch)?
Today, the Technical support checked my screen using the gray.html and it did not appear. And She said it is a normal behaviour to have an image persistence, because the retina bla bla bla (i don't remember exactly) and just dont leave the laptop too long.
http://r238.local/display/gray.html
Just now after playing a Chess (appx 30 minutes) , and run that test. The image persistence appeared and I guess I need to make appointment again..
Any solution and suggestion?
or We will stick with what the technical support said "Normal Behaviour" ?

The warranty entitles you to complimentary phone support for the first 90 days of ownership.
If you bought the product in the U.S. directly from Apple (not from a reseller), you have 14 days from the date of delivery in which to exchange or return it for a refund. In other countries, the return policy may be different. If you bought from a reseller, its return policy applies.

Macbook Pro Retina 15" flashing image/icon of world on screen at startup

My Macbook Pro (retina 15"), flashed an image/icon of the world when started up, and it had to be restarted before starting up properly. What's the reason for this? Is this an issue?

Search on globe at startup.
When I did up came some answers from way back in 2006.
It said to go to preferences startup & select the start up. I tried that & then restarted & while it seemed to take awhile then the rest has been faster.
It was saying something about losing where to find the start up so it was hunting until it found it. Something like that.
I'm on a 2012 13" MacBookPro running Mavericks.
Before this I had noticed it flashing back & forth between a gray screen & Mavericks screen on boot up (I was back & forth while booting & came back to see that. knew it wasn't good so shut down. Waited a few & then started up. It worked.)
It was funny since I had been wanting to go to Apple store & had talked about going w sister in law. That morning they said they were going in because hers wasn't working at all. So then I booted up & had that happen.
So I called & made a Genius bar appt. They checked & didn't find anything, but I had been getting the globe on bootup which kind of concerned me. Also its been rather slow booting & shutting down.

MacBook Pro Retina "Gets Hot when viewing RAW images"

MacBook Pro Retina Gets really Hot when viewing RAW images - somebody has this issue? Solutions?

Welcome to Apple Support Communities
First, download Temperature Monitor and tell us the temperatures of the MacBook > http://www.bresink.de/osx/TemperatureMonitor.html
The MacBook Pro with Retina display is made of aluminum, so it's normal that it gets hot. However, if the temperature inside is very high, fans will turn on automatically. If this doesn't happen, it may have a hardware problem

I have a MacBook Pro Retina (2,3 GHz Intel Core i7 - 8 GB 1600 MHz DDR3 - Intel HD Graphics 4000 1024 MB). I use KompoZer for my website, but after installing OS X Yosemite it doesn't work right (I cannot see images in the website).

It's beta open source software so I'm not surprised. It does't look to be too active a project, so I don't know if it will help or not but you might be maybe better off posting a bug report on their Sourceforge page here: http://sourceforge.net/projects/kompozer/

Macbook pro retina ghost image problem

I have heard about the burn-in problem on macbook pro retina display especially on LG screen. After I got my macbook retina for 3 months, the ghost image problem become really really unacceptable. After 4~5mins, the image on screen will burn in obviously for quite a long time. IT IS VERY OBVIOUS!! So I drop by apple store and find a genius, he did a persistence test on my macbook. The test is under a very low brightness, and I can not even know how he was operating. After 6 minutes, he said there is no burn-in problem. He explained that, if my macbook pass the test, it means my screen is within inspection. But I can tell if this screen is good, APPLE you should take a look at your inspection and change it RIGHT NOW. Everyone of my friend who have seen the problem on my screen says it is unacceptabe, how can it be within inspection? If anyone need a photo of that, i will provide.

If they replace your MacBookPro, you can avoid a service charge for runniing the back-up for you.

Macbook Pro Retina Image Persistence

I'm experiencing fairly bad screenghosting on my Macbook Pro Retina display (15 inch, Mid 2011) and the last time I took it to be repaired the Apple Store had no openings for repair anytime soon. This model has an LG screen, prone to image persistence. I assumed I would go back another day to get it fixed, since then it has gotten much worse to the point where I need to take this in very soon. Because of this reason I decided to check my coverage. My one-year limited warranty expires on August 7th, 2013. It is currently 12:05am August 7th. Do I have all of today to get it dealt with? Will they cover this type of issue past warranty because of manufacturing fault? Am I out of luck?

You'll only know if you take your machine in TODAY. No one here from Apple so we can't conjecture what their response will be.
If you're lucky, you'll get a Samsung display without the pink/yellow tint.
Call immediately.

Macbook pro retina with ghost image problem

Can i claim my retina display that have ghost image problem?

Hi there, I had the same problem with my Macbook Pro 15`` Retina. And here is how you can find out if you have ghost image problem. There are two retina display manufacturers for Macbook Pro Retina`s LG and Samsung. And if you are luck you will have the Samsung Retina Display on your mac. Here is how you can find the manufacturer for you Macbook.
Go to your Applications folder and launch Terminal. Paste in the following and hit return:
ioreg -lw0 | grep "EDID" | sed "/[^<]*</s///" | xxd -p -r | strings -6
Look at the beginning of the second line to see which manufacturer made your display. If it starts with LP then you have an LG display. Samsung displays start with LSN.
If your display shows LP you might have this problem for sure. So here is how you can test your screen.
A simple test to check your Retina MacBook Pro display for image retention also reported as "ghosting"
http://www.mitchmalone.name/retina-test/
Run the test for 10 Min. and you will find out if you have this problem.
And if you have it, and if you are still under waranty the Apple will replace the display with Samsung for free of charge. I hope this information helps.

MacBook Pro Retina retained image policy

There are many reports of the MacBook Pro Retina suffering from a retained image, a ghost image, it slowly fades but is a real nuisance especially when doing graphics work - something Macs are meant to be good for. Certainly my MacBook Pro Retina has the issue and it appears to be getting worse though that may just be because it is annoying me.
Anyway, my question is whether Apple have any clear policy on handling this?
Thanks.

At this moment, Apple doesn't have any replacement program for the MacBook Pro with Retina display, mainly because all of the MacBooks Pro with Retina display are in warranty at this moment, so Apple will repair or replace the damaged Macs for free.
Normally, if the problem shows up during the first 14 days after the purchase of the MacBook Pro, Apple will give you a new MacBook Pro. If it happens after, they will just put a new display. This problem is caused because of some defective displays, but this problem is being fixed just because Apple is installing different displays from a different manufacturer than the one that provided defective displays for the MacBook Pro with Retina display

FaceTime Camera Images Look Poor on New Macbook Pro Retina Models

I received my new 2012 Macbook Pro Retina display model yesterday. When doing Facetime last night, others on the other end were commenting how poor the image coming from my end looked. Then I tried it on my iphone 4S and it was amazing how much better the picture of me looked on the phone versus the macbook. Today, I went to the Apple store to compare my new computer to the Retina display models on the display. Their camera images honestly didn't look much better than what I have on mine (but for example, the new Macbook Air's images look much more realistic). Why is this? How can the HD Facetime camera in the Macbook Pro produce less realistic images than the lower resolution iPhone 4S or Ipad cameras? Any help or insight you could share would be appreciated.
Thanks!
Jason

Thanks for the update, Jason.

.... Unfortunately, the new laptop has the same issue...
Of course what is seen on Retina versus non-Retina display will be different. That is a different issue from the video quality your video contacts experience. However, the fact that you see the same problems at your home on a second new Mac means you will need to do some more extensive troubleshooting involving another trip to the Apple Store.
Rather than merely looking at displays of the live camera, I suggest you compare how the FaceTime video looks when received on your iPhone while in the Apple Store. If necessary, you should test your new Mac plus some of the Store models, too. Taking your new Mac & iPhone back the the Apple Store and connecting there will have the added benefit of eliminating possible internet connection issues at your location.
At the Store, you can compare how your new Mac's video transmissions (iChat, FaceTime, etc.) and video from some Store display cameras look on your iPhone as a receiving device. If all are "bad" on your iPhone, you can also compare video transmissions received on one of the Store's devices to be sure it sees the same video problem as your iPhone.
While connected via wi-fi in the Apple Store, if the FaceTime video transmissions from your new Retina MacBook Pro (RMBP) to your iPhone is lower quality from that of the Apple Store's RMBP FaceTime to your iPhone, it seems to me that the Geniuses should determine whether your new RMBP needs service or (highly unlikely) is a second "bad" Mac that should be exchanged for a RMBP that works properly. This time, test the fix BEFORE you take it home again.
If, every RMBP you test in the Apple Store looks worse than the video sent from all other devices, you are most likely correct that some software needs to be updated for video quality.
All this testing may take some time, so plan ahead. Perhaps you want to make a Genius appointment. However, although the Geniuses were unable to give a definitive answer other than swapping RMBPs during your last visit, they may have since found an official answer to your questions.

Macbook pro retina indecisive please answer :)

So im buying a macbook pro retina and im upgrading the standard one from 2.3 to 2.6 i7 quad core with the 1gb graphics 256 ssd etc and i was thinking about getting the 16gb ram but didnt know if it was worth it here is what i will use the computer for
1: Downloading movies/tv shows high quality and playing them so for example 4 - 5 gb 720p movies.
2: Mulitasking on the net so youtube/email/facebook/browsing etc also i always have alot of tabs open
3: University work writing notes/ listening to lectures
4: Play games FIFA/ few popular shooting games etc.
5: Itunes - listening to music
6: Multitasking so movie might be open while the internet is open and microsoft word might be running and itunes might just happen to be etc.
7: Also being a laptop i will move the computer a bit so taking it to uni etc.
So my question is; is the 2.6 i7 quad core 256 ssd and 1 gb graphics 8gb ram enough to do everything smoothly and with no hassles or should i get the 16gb ram and also with the retina display will it show me a significant difference playing high quality movies. Also i do have a hard drive and will not overfill the computer just with music and work stuff.
THANK YOU

to be honest - i jumped the bandwagon when the Retina came out because of the screen. when watching movies, it's a very nice screen and when browsing the web, that too was great.
here's my issue - Photoshop, Word and Excel, the Retina screen is no good to me. Images are blurry, fonts are pretty bad. If you plan on using Photoshop, Word and Excel, go for the non-Retina with Anit Glare Screen instead.
Until Adobe and Microsoft updates their software, my Retina will be a paperweight - So far, since I got it almost 3 weeks ago, i've only used it a few times - i tend to use my late 2011 15 inch Macbook Pro more.
So I'll leave it up to you to decide - if you search around, you'll see that most Retina owners complain about Photoshop and MS Office....Other than that, it's a very nice Macbook -

HT1338 macbook pro retina webcam poor quality

I am very happy with my MacBook Pro Retina Display.
However, the webcan produces very poor image quality, feels like out of focus. (using facetime, imessage, skype, all software the same)
I went back to my Macbook pro 2011 version, the same 720p webcam, produces very clear picture.
I read quite a few people having this issues but looks no firm answer. I hope its a software issue.
I wonder if Apple is looking into this problem.
Thanks

Yes, I have recently noticed the exact same issue. RMBP has very poor webcam quality and is certainly not 720p (HD) display.
I have compared it to my desktop webcam, a logitech (HD720p camera) and images were by far much more superior for my logitech webcam.
I hope they do a software fix on the cameras.

Unfortunately, that is not possible. The computer only can "output" your display image, it cannot "input" an image from an external computer and display it on your MacBook's retina display.

MacBook Pro retina 13" (late 2013, Haswell) why is the highest resolution rendered in 3360x2100, which the system obviously can't handle?!

Hey Apple and Apple users,
I just recently switched from an MacBook Air (mid 2013) to the new Haswell MacBook Pro retina 13" (late 2013 model).
The main reason to do so was the better screen and the option to run higher scaled resolutions, as advertised.
I was willing to trade in the Air's low weight, smaller formfactor and the extra batterylife for the better screen.
When it comes to resolutions:
1280x800 is just a joke nowadays, why is the MacBook Pro still based on it? 13" and 1440x900 work quite fine...see MacBook Air.
1440x900 is okay in everyday life situations, but sometimes you just need "more space" as the third scaling option calls it as well in the display-settings.
1680x1050 on 13" can sometimes be challenging, but it is really fine if you need to work and have a lot UI elements to deal with (Photoshop etc.)
So 1680x1050 scaled on the 2560x1600 screen would be my daily driver for work. So I expected a scaling factor of "1.5238..." (2560/1680) will be used most of the time.
Frankly spoken...I am really disappointed by the 13" retina MacBook Pro and the way OS X Mavericks is handling the scaling.
It obiously works well and responsive with the 1280x800 non-scaling resolution ("best for retina, scaling factor 2: 1280 --> 2560).
Is still "okay-snappy" at 1440x900 (scaling factor 1.777...: 1440 --> 2560).
But it totally breaks down at 1680x1050 (scaling factor 1.523...: 1680 --> 2560).
I use "Mission Control" all the time and it is stuttering and slow...overall a sluggish and unbearable experience.
The same goes for Desktop-Switching by swiping the screens or resizing and moving windows and files around.
So I was wondering why...and then I noticed that when taking a screenshot of my entire screen (CMD + 3) the image size of the screenshot was 3360x2100 and not the expected 2560x1600.
This means Mavericks is not scaling the UI with the appropriate factor (see above). For retina MacBooks it ist simply rendering one pixel of the classic, non-retina Interface in now 4 pixels (2x2) and sending this straight to the screen, which then "scales" it down to the resolution it is able to display.
Why is this bothering me? – Because the machine has to do a lot more work to render the higher resolution that can't even be displayed, due to the screens limitations.
2560x1600 = 4096000 pixels = 100%
3360x2100 = 7056000 pixels = 172%
This means the MacBook has to render 72% more information than actually can be displayed on the built-in screen and are just lost.
Of course this makes the overall UI feel sluggish and idly! Especially with the not that performant Intel Iris IGP and no dedicated graphics card.
All this extra "rendering" just results in a worse battery life due to the extra work that the graphics card and CPU have to do.
First, Apple...are you serious about this?
What can we do about this?
Is there a way to have this properly scaled?
Thanks in advance to everyone.

Okay...I thought deeply about this issue.
Even looking into ways to maybe fixing this on the software side. But it occured to me that this is to deeply embedded into the system that it won't be possbile to come up with a sufficient third-party solution.taht
The problem is that there is no intermediate step inbetween "standard DPI" graphics and "HiDPI" (image-resources named "[email protected]").
But there should be one, to minimize the amount of image information that needs to be processed by the device.
This effects especially the MacBook Pro retina 13", as it has the less powerful Intel Iris IGP, when performing on the highest scaled resolution (equivalent to 1650x1080).
As well as the MacBook Pro retina 15" without a dedicated, second Graphics Unit,when performing on the highest possible scaled resolution (equivalent to 1920x1200).
Those devices don't have enough resources to handle the consequential "HiDPI" resolutions of 3360x2100 for the 13" and 3840x2400 for the 15" model.
(Comment: 3840x2400 = 9,2MP, which is more than the standard 4K resolution of 3840x2160.
I analyzed the scaling factors as follows:
Factor "2" to display 1280x800 on the 13" model and 1440x900 on the 15" model in HiDPI.
Factor "1.777..." would be required to display 1440x900 on the 2560x1600 screen of the 13" model.
Factor "1.714..." would be required to display 1650x1080 on the 2880x1800 screen of the 15" model.
Factor "1.523..." would be required to display 1650x1080 on the 2560x1600 screen of the 13" model.
Factor "1.5" would be required to display 1920x1200 on the 2800x1800 screen of the 15" model.
As all the models seem to have no problem with rendering the intermediate scaling step (1440x900 for the 13" and 1680x1050 for the 15" model) at HiDPI, hence with the scaling factor 2. There is no real need to provide the UI-elements.
But in my opinion there is a strong need for a "MidDPI" ([email protected]) intermediate step for all the UI graphic elements that wis based on the scaling factor 1.5.
This would result in the following:
13" MacBook Pro retina with 2560x1600 screen:
1280x 800 @ 2x = 2560x1600 (no surplus, native screen resolution)
1440x 900 @ 2x = 2880x1800 (the surplus of 1088000px = ~1MP can still be handled and compansated by the weak Iris IGP)
1680x1050 @ 2x = 3360x2100 (the surplus of 2960000px = ~3MP is too much for the weak Iris IGP)
NEW 1680x1050 @ 1.5x = 2520x1575 (with a small border of left=20px, bottom=13, right=20, top=12 pixels, which means ~2,2mm and ~1.3mm around the 1.5x scaled image!).
15" MacBook Pro retina with 2880x1800 screen:
1440x900 @ 2x = 2880x1800 (no surplus, native screen resolution)
1680x1050 @ 2x = 3360x2100 (the surplus of 1872000px = ~2MP can still be handled by the Iris Pro IGP)
1920x1200 @ 2x = 3840x2400 (the surplus of 4032000px = ~4MP can't be handled sufficiently by the Iris Pro IGP)
NEW 1920x1200 @ 1.5x = 2800x1800 (nu surplus, native screen resolution, no border needed!)
The big advantage is that all the graphics have already been remodeled for the HiDPI mode.
So scaling those "factor 2x" images down to "factor 1.5x" should be comparably easy!
Example:
Left: Traditional "standard DPI" icon of "all my files".
Right: "@2x.png" for the "HiDPI" modes.
Middle: "@1.5x.png" suggestions for the "MidDPI" mode; easily scaled down from the lovely HiDPI graphics.
With this simple introduction of the "MidDPI" modes a significant amount of processing power can be saved.
This not only improves battery life when driving those higher scaled resolutions, but also lets the user access those resources for what really matters: processing power for the primary job that the Mac needs to get done.
Thanks in advance.
