MacBook Pro :: External Display Flickering Static When Connected Thru HDMI Splitter

Jun 25, 2014

I have a Late 2011 MBP, just recently I also go an Xbox and wanted to hook it up to my external display that I have been using for a long time with no issues. I went and bought this: URL....to be able to easily switch between the two inputs. The xbox works fine, however when I view my Macs input the screen flickers a static image very frequently. 

I know what you're thinking, it's probably an issue with either a cable, or the device. But when I boot into Windows via Bootcamp with the same exact setup, there is no flicker at all. The display is a dell s2440L, the HDMI adapter is a rocket fish. 

Here are the troubleshooting steps I have tried: Resetting PRAM/SMCChanging out HDMI cables on both the Splitter output, and the inputs (I tried 3 different cables on both the inputs, and outputs.)Downgrading OSX to 10.7 (And then went back to 10.9)Lowering the resolution on the monitor (Lower resolutions flicker just as much, if not more.)Resetting the splitter by unplugging the HDMI cord powering it and plugging it back in.and of course, plugging my computer into the splitter input that the Xbox works fine on, as well as taking the xbox one out so the computer is the only input on the splitter. 

Like I said, the Xbox works fine, and even the computer works fine in Windows, but whenever I boot into OSX my screen flickers with this static. I should add, the display works fine when not connected to the splitter on OSX.

MacBook Air :: Doesn't Detect External Monitor Connected Through Mini Display Port To HDMI Adapter

Sep 8, 2014

I bought a MBA 13" last month and now I'm trying to connect an external monitor through a Mini Display Port-to-HDMI adapter and most of the times the display shows a message "No signal detected"...

I've tried all the possible combinations between the MAC and the Monitor but it would seem a random matter.

MacBook Pro :: Will A HDMI Splitter Work With It

Apr 7, 2012

I am going to buy a Mac Book Pro 13 inch 2.8 ghz. I was wondering if there is a way to get my mac to hook up to 24 tv's. I use them as mointors.  

They both have HDMI and VGA/sound. I noticed that apple said that the MBP could only hook up with 1 thunderbolt on the second the mbpro would go dark. But I was hoping to work around that. I found this device on the internet: [URL] I was wondering if it would work so I could have My email up on my macbook pro and on tv 1 have safari up and on the second tv have itunes up? I do not want them to mirror! I want them to both extend my display!

MacBook Pro :: Digital Audio Output (HDMI) On It When Cinema Display Is Already Connected?

Apr 22, 2012

I would like to connect my Macbook Pro to my hometheatre via HDMI. Normally no problem with the mini display port and an HDMI adapter, but the port is already used for the 27" cinema display... Is there another adapter available that let`s me connect both, an HDMI device and the cinema display to my Macbook? I only care about the sound - I want to get digital sound to my receiver. (I am not interested in the solution via airport express and then connect via analogue audio cable - I am looking to get a digital sound signal all the way through...) about Macobook Pro: mid 2010, 17", Processor  2.53 GHz Intel Core i5, Graphics  NVIDIA GeForce GT 330M 512 MB)

MacBook Air :: Slight Flickering Only On Dark Grey On External Display?

Sep 12, 2010

I have a 28" inch display attached to newest version of Air. Works ok except when I have a full screen on plain dark grey background, then I see a waviness or flickering effect. Like the dark grey in Iphoto background. Other than this, the other colors seems ok. Pictures are fine, even when dark. Maybe there's a slight flickering with dark blue. Any explanations for this.
using mini display port to dvi. Tried with a friends dual link display, was a little different, but still unstable looking in dark grey when it fills the screen.

Could it be just what it takes to make this color, or the Hertz, which is 60. Other than this, no problem with the screen.

MacBook Pro :: External Display With HDMI Adapter

Sep 2, 2010

I just purchased a 13" MacBook Pro. When I attempt to use a TV as an external display, I get a flickering blue screen on my MacBook, and absolutely NOTHING on the television. I am using a Moshi adapter that I purchased from the Apple Store. Despite HOURS on the phone with tech support, I can't get this to work. I know neither the adapter nor the cable are defective. Does anyone have a solution?

Macbook Pro HDMI Screen Static Flicker

May 25, 2012

I bought a new HDMI adaptor for my 17" Macbook Pro. I'm plugging into a full HD compatible TV, into an HDMI port.The result is a consistant switch between the actual correct display, and colored static. The rate of the switch is dependent on the frequency of the refresh rate, but there's no way to get it anywhere near comfortable to use. I have tried changing resolutions on both sides to no avail. Here is a video of the screen periodically flickering between display and static url...Also have tried other HDMI ports and cables, all of which are known to be in working condition. Tried restarting the tv and computer. Running out of ideas and hair.Troubled Mac User

MacBook Pro :: Unresponsive When Connected To An External Display - How To Know About It

Sep 26, 2010

I have a MacBook Pro 13'' (mid 09) and another MacBook pro 15'' (early 09). The problem below applies to both of them.

I often use my 15'' mbp connected to a usb keyboard, mouse, display etc. Basically it is used as a stationary computer that can be easily moved (to work/school etc). This is my main laptop so this is where I noticed the problem first. Sometimes when just using the computer as normal (using itunes, opera, adium etc) the OS X will just suddenly become very sluggish and unresponsive.

However it is not OS X itself, but the GUI! Example: if I move my mouse over the dock, it wont animate. If I try to do any finder related action the GUI response is way of and if I try to do something in the menubar I have to hold left click, if I let go it just closes the menu.

This goes for the application folder as well (I have it as a list). Normally it will just funtion as normal but when this problem occurs I have cant let go of the mouse button when moving through the menus because then the menu closes!

MacBook Pro :: Getting Static Pop In Audio When Speakers Connected

Sep 26, 2007

Just got my 15 LED SR Macbook Pro. When I plug my bose speakers in at my desk and listen to itunes, I am getting a static pop sound. Should I take it back or is it fixable? By the way, LG panel and no yellow 1/3 of screen. Initially thought it was yellow, but I calibrated it, and now it only looks yellow if viewed from the side. Head on, white. One thing I have noticed, when I watch movies on it in the dark with the brightness turned down (cause this thing is a torch), I am getting quick flashes when a screen has high contrast light and dark. I am very sensative to LCD flat panel TVs that use a colorwheel. Like a JVC dilila, I see rainbows! Is that normal for an led flat panel to see "quick white flashes of light"?

MacBook Pro :: How To Turn Off The Builtin Display When Connected To An External Monitor

Nov 21, 2010

WITHOUT closing the lid, because i like using the touchpad. i know that you can turn the brightness all the way down, but sometimes windows from the main screen randomly open on the other display. and it also slows down performance. i want to turn off the 13" screen as if the lid was closed. that way, the mac doesn't even see it.

MacBook :: Unibody Display - Connected To External Monitor - Black Screen

May 7, 2010

Well my unibody macbook display decided to screw up last night, it was working fine last night no problem. Connected to a external monitor. I fell asleep last night with front row left on, obviously it went to sleep and then I woke up and the screen was black. Now the LED lights are working, my external display is also working. The display settings recognize a screen being present (when I click detect displays and gather windows - 2 windows appear). Ive reset PRAM, SMC, reseated the RAM, control+shift+eject (which just made the screen flicker a little after turning it back on) and Im out of ideas. Its out of warranty and about about 18months old.

OS X :: DVI-HDMI Connection To External Display Stopped Working?

Mar 10, 2010

I have a macbook pro from fall of 2007. So far it has worked perfectly and I've used it with an LG full hd LCD for about 1,5 years. I use a regular DVI - HDMI cable.About a month back it suddenly stopped working. The TV just tells me "No signal".I didn't change any settings or anything. The computer still recognizes when something is plugged in as the screen flicks blue and the displays icon in the menu bar lists the TV with correct model and resolution. And if I have spaces turned on it changes from 4 to 8 "screens".

I have tried everything from rebooting the computer to resetting P-RAM.
I got a new cable, no difference. However when I tried the TV with my friends MBP, it worked. So the problem is definetly in my computer, not in the TV or cable.My OS X is Version 10.5.8 Leopard.

OS X :: External Display Blinks/flashes When Connected To MBP

Jun 12, 2010

I use my MBP connected to a Dell U2410 and everything has been ok for the last 5 months or so (I got the MBP around the beginning of Feb.). However recently, my display will start flickering (blinking) a blue screen up to the point that it is completely unusable. Often if I simply unplug the mini displayport from the mbp and plug it back in again, everything goes back to normal for awhile. Just now I was able, between flickers, to switch from the integrated graphics card to the dedicated (?) graphics card. Although I did get a few flickers logging back in, so far it's been ok.

Mac Mini :: External Display Is Connected When Powered Off - How To Know About It

Aug 16, 2010

I have a 2009 Mac Mini connected to a 22" LG monitor via Mini-DVI port and it's also connected to a 50" Pioneer Plasma (in the next room) via Mini-Displayport. Everything works perfect except that when I turn off the Pioneer Plasma, my mouse can still scroll over from the LG monitor to the Plasma.

I've also noticed that my screensaver is laggy even when the Plasma is turned off (usually that happens when it's drawing the screensaver on both screens) so it must still be sending a video signal out of the Mini Displayport.

MacBook Pro :: Static / Snow On Second Display?

Oct 8, 2009

I just walked in the door and shook my mouse to wake up the screen. My Macbook Pro's display came up instantly (and normally) but the second monitor... a SyncMaster 220WM hooked up via mini displayport to DVI, showed nothing but snow... like exactly what you'd see if a TV station wasn't getting reception.

I'm running on the 9600m GT at the moment. 2.66Ghz C2D mid-2009 MBP unibody.

I waited about two minutes... and the image of my second desktop came back to normal in an instant. No excessive fan or heat... no need to restart, no kernel panic... nothing of that sort. And the kind of static that showed up again reminded me of either a TV channel with no reception... or the static you see when you boot into a PS3 game via HDMI... you get a momentary bit of static when it negotiates the HDCP signal.

I never encountered this issue using the same cable connected to my SR MBP with DVI.

Is this a graphics card issue? or an issue with the mini-displayport DVI adapter? Was it having a hard time negotiating HDCP?

MacBook Pro :: Getting The Flickering Display - Mid-2012?

Jun 29, 2012

There are random black horizontal lines, constantly on the screen.When I leave the setting of 1280x800 (default), the defects disappear, only small distortions, which makes me think that the error can be corrected via software update. As the Lion was on 10.7.3, I upgraded to 10.7.4 to see if improved. But the errors persists.At the end of the video, the lines are most striking, becoming impossible to work.

MacBook Pro :: Why Does Display Keep Flickering With Dots

Jun 4, 2014

It used to stay like that until either I'd move my mouse over the area, scroll the page up or down, or refresh. It only seemed to happen in browsers, not in Finder or anything. It's the worst when watching videos on YouTube or any kind of flash video. But works fine on Netflix. I say "used to" because the above screenshots are from July 2013. I sent my laptop away to Apple but they were "unable to reproduce the problem." I figure they just left the laptop open and waited. You have to use it like it's YOUR laptop and then it will happen. Anyways, now it's happening more often. Except it's just a flicker. Over and over again. I could record video of it, if necessary. 

So, I'm running 10.9.3. I'm not sure what other information is needed. But my computer is up to date. I don't have warranty. I just want to know what is causing my computer to do this.

Info:
MacBook Pro, OS X Mavericks (10.9.3)

MacBook Pro :: Is It Possible To Use When Connected To LCD TV Via MiniDVI To HDMI

Sep 9, 2010

I currently use an LCD TV to play movies from my Macbook Pro via the MiniDVI - HDMI cable. At the moment I just connect everything up and then use the Mirror Display in the arrangement settings. So my laptop screen is the same as my LCD TV screen. What I want to be able to do though is watch the movie on the LCD TV and also use the laptop to go on the internet, is this possible?

MacBook Pro :: Display Flickering With Red / Green Pixels?

Mar 29, 2010

Sometimes the LCD display goes into this mode where in some areas you see red and green pixels flashing. I have taken a few pictures, which obviously don't render the flashing effect, but give you an idea of what it looks like:

[URL]

This is a MacBook Pro pre-unibody The graphic card is an ATI Radeon X1600 I ran the TechTool Deluxe tool to test the video RAM (and everything else), but it didn't detect anything wrong I have never seen this when the laptop is connected to an external monitor This doesn't happen that often; say 1 times out of 10, usually after the laptop comes out from sleep. The issue stays for a few minutes and then goes away until next time, so I am unlikely to have the problem when I go to Apple Store for service.

MacBook Pro :: Screen Flickering / The Display Goes Dark, Almost Black, For A Second?

Sep 5, 2010

So I've got my MBP that I've had for about 4 months, the thing is. It just recently started to have screen flickering issues. I'll be sitting doing w/e as usual and all of a sudden the display goes dark, almost black, for a second, then comes back up again. I have yet to find any trend in when this is happening, but it is definitely happening on battery as well as plugged in, but it seems to be getting worse.any one have any idea what this could be, something I can fix on my own, or should I take it in?

MacBook Pro :: Brand New 17" Display Lines / Flickering / FAIL

Jun 30, 2009

I have a new 17" uMBP that I've owned for just a few days. I noticed yesterday that while I watching a video that i had strange green/red lines (horizontal) appear across the screen and flash/flicker. I freaked out and closed the lid, putting the unit into sleep, and opened it again and it all stopped. Today, I was using it again as usual, on firefox/etc. when it started happening again. Horizontal lines across the screen, the entire display flickering and screwing up and finally going black. I don't know what's going on, but I know this definitely isn't supposed to happen. I took a screenshot during the flickering/lines/etc but the screenshot came out perfectly fine unfortunately. I'll try and get it on camera next time.

I have all software updates installed. I tried resetting PRAM. The flickering I'm talking about isn't minor, it's actually absolutely horrendous and the computer is completely unusable when it's going on. It ultimately leads to a black screen. Anyway, this is all on the 9400, and I have no idea what's going on but I definitely know this isn't supposed to happen. UPDATE: I booted into Windows via bootcamp and it STILL happens. I also connected it to an external display(which works perfect), which leads me to believe that it's 100% a hardware issue. I'm taking it back to the apple store, enough said. This is my first Mac and I can say I'm definitely not happy to be having such issues with a $2500 machine.
