Macbook Pro Retina problem connecting to external monitor

Hello Community,
I've been experiencing a problem, I bought a 13' Macbook Pro Retina. Not quite a cheap machine.
But when I connect through HDMI to my HP 23xi , the screen gets blurry and cut. I tried messing with the configurations, but it simply won't get better.
I presume it's because it is retina, of course. But I bought this monitor, a quite nice monitor a month ago, and I do not want to sell it nor throw it away.
What should I do?
My Kindest Regards,
Luisvf7

Hi luisvf7,
So it seems you are having issues with your MacBook Pro not displaying properly on your external display. It does sound like a frustrating situation. Let’s see if we can get you up and running.
I would suggest that you use the steps in this article to troubleshoot the problem -

New Macbook Pro Retina is pixelated on external monitor

I have recently bought a Macbook Pro Retina Display 13" and when I connect it to my external monitor (Samsung) with a HDMI cable the screen is blurry and pixelated. I have connected my old macbook to this monitor with no problems. I tried adjusting the settings etc and some other tips I found online but nothing has worked. Has anyone else had any luck rectifying this problem?
It's a massive pain as I the monitor is reasonably new and I need it in order to study comfortably.

I have an HP 2311x as well. I'm using an HDMI cable and am not having any issues getting the screen to display. I know you said the cable works with a PC but have you tried a different HDMI cable just in case. It might be worth a try. Other than that, I'm not much help.
The issue I had when plugging this monitor into my MBP retina was that the image was very blurry on the HP 2311x. I almost gave up on using it and was going to just buy a Thunderbolt display but after much research I found a custom firmware update that fixed the underscan/blurriness issue. So be prepared for that if you get the screen to display.
If I can find that resource, I will post it here.
Good luck!

Macbook Pro Retina problem connecting to HP 23xi

Hello Community,
I've been experiencing a problem, I bought a 13' Macbook Pro Retina. Not quite a cheap machine.
But when I connect through HDMI to my HP 23xi , the screen gets blurry and cut (which I was able to fix in the setting). I tried messing with the configurations, but it simply won't get better.
I presume it's because it is retina, of course. But I bought this monitor, a quite nice monitor a month ago, and I do not want to sell it nor throw it away.
I bought this Mac to do web design , but this is not the outcome I was expecting at all.
I've seen the other post about the RGB fix, altough I haven't tried it because it isn't very pratical, my problem is not the color, but rather the pixelated resolution that appears on the display.
What should I do?
My Kindest Regards,

This question was solved.
View Solution.

Looking at the specs for the MacBook,
Thunderbolt digital video output
Native Mini DisplayPort output
DVI output using Mini DisplayPort to DVI Adapter (sold separately)
VGA output using Mini DisplayPort to VGA Adapter (sold separately)
Dual-link DVI output using Mini DisplayPort to Dual-Link DVI Adapter (sold separately)
HDMI video output
Support for 1080p resolution at up to 60Hz
Support for 3840-by-2160 resolution at 30Hz
Support for 4096-by-2160 resolution at 24Hz
I would consider using a Mini DisplayPort to Dual-Link DVI adapter for Thunderbolt digital video.
You will not achieve the 2560 x 1600 display resolution that your MacBook Pro is capable of on your HP display as the display is not capable of that. Specs for the display

MacBook Pro Retina Wont Connect back to Monitor

Hey Everyone,
I have a MacBook Pro Retina Early 2013 15in that is running OS X Yosemite - 10.10.2 - Graphics Card: NVIDIA GeForce GT 650M 1024 MB
At Work for the past 1.5 years i have been connecting to a Dell Monitor via a DVI to HDMI Cable to use as my primary screen and have never had any issues. During the day I often present on the projector in the BoardRoom a Dell 4610X using a direct HDMI cable.
The issue: Ever since I have updated my laptop to Yosemite, every time i connect my macbook to my monitor after its been connected to the projector it will no longer connect. The monitor will recognize that there is something connected but it wont show anything. Even if i try another display in the office the same thing happens. The issue will always resolve if i restart the computer.
Recently I had an issue with the Logic Board and it was replaced by an Apple Certified repair shop. This issue was happening even before the logic board was replaced and it is still having the same issues now, so I don't believe its an hardware issue.
Although this issue is not critical, its a nuisance to re-start my laptop each time i get back to my desk after a meeting in the boardroom...
I would high appreciate some help on this!!
Thanks in Advance

Something else to check ..
Open System Preferences > Network then select the Wi-Fi tab.
Drag the school wi fi network name to the top of the list.
You can open System Preferrences by clicking the System Preferences icon in your Dock
Or click System Preferences from your Apple menu icon top left in your screen.
Or, from your Applications folder.

Macbook Pro retina + Samsung LED 24" external monitor

Hi all, I just bought Macbook Pro 13.3" Retina and im having some troubles.
When I connect those two via VGA adapter I see some strange artifact effect on external monitor.
I dont know hot to name that artifact but it is the same thing that you can see when you take your camera or smartphone and try to record old tv screen for example. You will see that parallel lines goes up or down. This effects is easy to notice when you put something with dark background on external monior (like Unity3D Pro IDE with dark skin in my case).
The interesting things are:
- when I switch external monitor from VGA adapter connection to HDMI-HDMI then everything works fine with no artifacts.
- when I'm using VGA adapter and connect Macbook Pro to another external monitor (AOC 24" LCD) then everything works ok aswell.
- when I take my Samsung LED monitor and connect it to another PC (Windows 8) with VGA everything works great.
So I belive that this issue is related to all three of them (MacbookPro + Sasmung LED + VGA adapter) and I really dont know who to blame and what to do.
Dose anyome have an idea how to solve this and what to do?]
thanks

My 2011 MacBook Pro 13 stopped seeing my external monitor

Have you tried resetting the PRAM? shutdown the machine, hit the power button then hold down the option and command keys with your left hand, while holding them down with your right hand use your pinky to hold the 'P' key and index finger to hold down the 'R' key. hold them down until you hear the 'bong' sound twice then release the keys and let the machine bootup.
Also try resetting the SMC. Shut the machine down. Hold down the 'shiftctrloption' keys with your left hand, right hand hold down the power button for 10 seconds then release all. Power up the machine as normal.
Hope this helps. Pls update us and let us know if that helps!

I cannot get my Macbook Pro retina to connect to my BT Home hub.

Hi,
I cannot get my Macbook Pro Retina to connect to my BT homehub either wirelessly or through ethernet using the thunderbolt adaptor. I know that this is a problem with my IP address as in Network Settings it tells me that
'Thunderbolt Ethernet has a self-assigned IP address and will not be able to connect to the Internet.'
I know that my internet connection is fine as I can plug the ethernet cable back into my PC and it works fine. Also, my phone and ipad connect wirelessly just fine.
Bt have told me to contact Apple, but I can't get hold of Apple till tomorrow.
Amyone know how to overcome this?
I did also find my IP address and enter it manually, at which point netwrok settings showed my ethernet connection as green and connected, but it still wasn't working.
Thanks

Same for wifi. I have put in my IP address manually for the wifi network and it has gone green and connects to the hub, but gives me an exclamation mark on the wifi bar and still doesnt connect to the internet.
I am writing this whilst connected to the internet on the same laptop but connected to BTFON which is a really slow public network I have access to as a BT customer.

Can't connect Macbook Pro Retina to Dell P2715q 4k Monitor

I received a new Dell 4k P2715q monitor on Friday. It came with a mini DP to DP cable which I immediately hooked into the Thunderbolt port on my 15-inch, Mid 2012 Macbook Pro Retina. It worked beautifully on Friday all through the day. Was very happy with my purchase.
Took the laptop home over the weekend and brought it back today.... plugged into my thunderbolt port again and nothing.... Go HDMI to the monitor's HDMI and it works but only up to 1080p in 30hz which is no good. So the monitor still seems to be working but the Macbook won't recognize the monitor through the Thunderbolt (mini DP) port.
Any thoughts? Talked to Dell support which was worthless except to verify that the monitor didn't get fried over the weekend and also talked to Apple who suspected that it was maybe the mini DP cord that Dell sent with the monitor. I can't believe that a cable went faulty over a weekend when no one else was in my office.....
Thoughts? Thanks ahead of time!

Il mio macbook pro retina problema al monitor

Salve a tutti, il mio macbook pro retina, ha un problema al monitor, ovvero rimango impressionate le immagini sullo sfondo, e non vanno via... Se porto il mio mac in assistenza lo aggiustano o lo cambiamo ? L'ho comprato da due mesi, e quando è stato assemblato, ho fatto aggiungere della ram e ho aumentato il processore, ovviamente me lo faranno riavere con gli optional ? E sopratutto, quanto tempo ci impiegheranno, visto he dovrei utilizzarlo per studiare...
Grazie mille, e chiedo immensamente scusa per il disturbo...

Google Translate says you are speaking Italian and in English you are asking: / Google Translate dice che si parla italiano e in inglese si sta chiedendo:
I bought a macbook pro retina (15 "2.3GHz 8GB Ram) 2 weeks ago, so far so good. Mac has become slow, especially in view of the graphics. Continuous there is a lag window of icons, as if the card nvidia video does not start and the mac was using the shared video card. I do not know what to do has anyone had similar problems? should I contact apple?
Of which I say / Di cui io dico:
You should not be experiencing any lag at all on a Macbook Pro Retina. Therefore I would suggest you contact Apple. Here is their information:

Can the late 2013 Macbook Pro Retina 13" power 2 external Dell UltraSharp U2713HM monitors at full resolution?

Hi, I'm looking at buying the current Macbook Pro Retina 13", but I'd like to use it with 2 Dell UltraSharp U2713HM monitors http://configure.euro.dell.com/dellstore/config.aspx?c=uk&cs=ukdhs1&kc=305&l=en& oc=U2713HM-Black&s=dhs&sbc=dell-u2713hm
My plan was to use the the thunderbolt ports to the monitors DisplayPort plug. Can the 13" Macbook Pro drive 2 external screens @ 2560x1440 I'm happy to shut the macbook lid if necessary.
If the 13" can't do it, can the 15" model with it's discrete graphics card?
The Dell UltraSharp U2713HM – it’s everything you could want in a 27” monitor – screen brilliance, comfort and eco-consciousness all rolled into one
27-inch (diagonal) VIS with LED backlight
WQHD resolution, 2560 x 1440 at 60 Hz (Max)
178°/178° ultra-wide viewing angle
In-plane switching technology
Customizable brightness from 50 to 350 cd/m²

More than 99% sRGB (deltaE < 5)
DisplayPort 1.2, HDMI, DVI and VGA and USB 3.0 ports
Pivot, tilt, swivel and height adjustable (115mm)
Arsenic-free glass and mercury-free LED panel
Why not the Apple Thunderbolt screen, well I prefer a non-reflective screen in the office, but If I can't do it with the Dell's can it be done with 2 27" Thunderbolt monitors from the 13" Macbook Pro?

In a word, yes.
The video out capabilities for the 13" and 15" retina MBPs are the same.

MacBook Pro Retina Wireless Connection problem

I recently purchased a MacBook Pro Retina (late 2013) w AC wireless capability, and I have not been able to connect to my wireless network at work. Other computers, including my previous MacBook Pro (mid 2008) and my iPad 3 are able to connect to the work network without problems and I have no problems connecting my new MBP to my home or other networks. I have Windows 8 on a Boot Camp partition, and when my MBP is booted under windows, it still does not connect. My MBP is running OS X 10.9.4. My work wireless network uses a Linksys Wireless G Access Point model WAP54G v.2. Rebooting the router does not help. When my MBP tries to connect to the work wireless network, the status in Network Preferences says "Wi-Fi has the self-assigned IP address 169.254.216.147 and will not be able to connect to the Internet." Any help or suggestions would be greatly appreciated.

Hi Jackso,
Welcome to the Apple Support Communities!
For troubleshooting a self-assigned IP address, I would suggest reading over and using the following article as a reference and resource.
Internet connection does not work with an IP address space of 169.254.xxx.xxx from ISP, router, or manual configuration

New MacBook Pro Retina with NEC 27 inch monitor

I've got a new MacBook Pro Retina and I'm trying to use it with my NEC 27 monitor. I connected the two via Apple DVI to Thunderbolt adaptor, but I can only get the monitor to operate at 1500 pixels with the MacBook Pro even though my monitor supports 2560x1440pixels. This is really frustrating since I purchase this lapto to use with my monitor. Any advice? Thanks, Lucian

When going to the 2560x1440 ( or 1600) resolution you will need the dual-link DVI adapter (along with a dual link DVI cable, of course). The single link will work...but at lower resolutions.
