MacBook Pro :: Sees External Display But No Output?
Jun 14, 2012
13" MacBook Pro 2.3 Intel i5 8gb ram 500gb hybrid Hdd OS X 10.7.4 Thunderbolt port mini display port to DVI and with HDMI adapter works fine mini DP to VGA adapter will see VGA monitor (tested on 5 different monitors) but will not display anything on external display. Newer displays just go into power saving mode and older VGA displays just are blank. Even tried DVI to VGA adapter on mini DP to DVI adapter with same issue. I'm guessing I have no analog output from the DP port. tried the SMC and PRAM reset with no results.
I use studio monitors (speakers) with my macbook pro 13 (2010) and a samsung 1080p external display. Whenever I plug the display in, it causes a hum in the speakers, and weirdly the pitch of this hum varies depending on the brightness of the contents of my screen. I have borrowed my friends USB audio interface, and I still experience the same problem, except the hum is now cleaner and louder. I would assume this rules out problems with the internal sound card. Â
In both cases, the hum stops when the sound card/output 'goes to sleep' (ie after there has been no sound output for a few seconds). Also the hum only starts when the computer is outputting to the display. In the few seconds between physically plugging the display in, and the mac sending a signal to it, there is no hum. This is why I'm starting to think this may be a problem with the computer and not the monitor. The monitor is a cheap (£120) monitor - samsung p2270HD, and also has a TV tuner and stuff.Â
What I need to know is whether this is a problem with the computer, bleeding the signal through to the sound output, or whether it's my kind of crappy monitor. Another thing, might it help if I changed from VGA (analogue) to DVI (digital) video output?

My iMac G5 resizes its display on its own. The screen will suddenly go dark, then reappear in a smaller size with a black band around the edges. Eventually it will resize again to the correct display. I found when this happens it is "seeing" two displays, both the iMac, and an obviously non-existent "VGA Display." This doesn't happen all that often, and othewise everything seems to be working perfectly. Is this a software issue I can take care of, or an early warning sign of something more perfidious?

FCPX (latest version) recognizes my external hard drive (my book 4TB) as a camera. Didn't dave this problem before, so when I'm importing to my project the the hard drive is listed as a camera and the program starts to scan through all files! this means that the ram memory is filled i no time! Is it something in my settings or is it the new version of fcpx that is playing tricks on me (not supported had drive?)
I give presentations regularly, and I always lock (with password) my MBP if I need to leave the room for a quick break. However, I often need to leave the secondary display projected on the big screen. Is there a way to keep the secondary display showing even when locking access to the MBP?
I've got quite a simple question about an MBP and an Xbox 360, which I'm sure some have asked and others have answered before, but I'm looking for a straight-forward response given the situation I find myself into. So I've got the two devices, and I'd like to use the MBP's display as a video output for the 360. What I've also got is a VGA adapter for the 360, so I could connect it to a monitor instead of a TV. So basically, is this achievable, and if it is, what else do I need, in case I need anything else? Sorry for the improper way of writing this message, but all I have is an HTC Desire, and I find it quite difficult to type very well.
Initially My macbook pro 13" was working with Sharp 32" display in mirror display with closed lid, after ward I change the resolution to 480p , then TV screen is black now with a message incompatible output format. How to change back to original resolution
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) Â
I picked up a MBP 15" core i7 high res laptop on Friday. I actually ordered one of those mini displayport -> HDMI awhile back (was going to get a mini, decided no), however when I hook it up to my plasma it won't adjust the resolution to 1920 x 1080, I checked "display" in system settings but it won't let me push it past the native resolution of the laptop screen.
Any suggestions how to get around this? Also it mentions on the website it can push sound over HDMI now, I wasn't able to figure that out either.
I have a MacBookPro, model: A 1278 (Mid-2010 13"). Is its mini-display port capable of delivering both video and audio output to a HDMI adapter? or just video output only?

if there is a way to use multiple external monitors on my MacBook Pro using the single DVI-output provided. From reading previous posts, I heard you can be able to use Matrox's DualHead2Go for splitting the DVI-output. Is this device capable with MacBook Pro even though Matrox device requires an Analog output?
I have owned my MacBook Pro since June 2010, and have always used a pair of independently powered (via adapter) external Dell speakers for audio output. Since upgrading to Lion about 1 month ago, I was having intermittent audio issues, which were resolved by re-starting my computer (not ideal but it worked). Today, the speakers just stopped working. The internal speakers work, but when I plug the externals into the headphone port, they don't produce sound. Earbuds in the same port also don't work (I know the earbuds are good). The external speakers are being recognized by the sound panel in system preferences.
MacPro 8 core Nvidia 8800, RAID card - arrived 2/25. Tried second monitor; monitor is blank (and turned on, and says "digital signal" when unplugging display connector from the machine, so it's recognizing the connection, monitor is fine on old G5). RMA'd for a new 8800, rec'd that on 2/28 - same result, so it's probably not the card. Tried 8800 card in different slots, so probably not a slot. Ram lights flash, HD spins, power light is on, so likely not power supply. Motherboard or RAM is only other thing I can think of, or maybe some kind of incompatibility with the 8800. Also, the fans on both 8800's run at what seems like full power when turning the machine on - is that typical for the 8800? Maybe that's a symptom of the problem; it's a lot louder than I would prefer.
while trying to make a presentation or simply playing a video from my MacBookAir over thunderbolt/HDMI table to large screen I am experiencing problems with audio only being played from the MBA and not the soundsystem built in to that screen (unless using a VLS application and manually selecting the audio output target).

How do you tell the MacBook Pro to output to the Apple Cinema Display when the lid is closed rather than go to sleep? I know you can use the ACD as a secondary screen OR as the only screen with the MBP lid closed. Is there a setting somewhere for this?
My external display (HP w2207) seems to conflict with my MacBook Pro (15 inch Retina display, early 2013) since I upgraded MacBook OS to 10.9.4.The external display works at initial boot of Mac but does not work after OS sleeps and I attempt to awaken, and while the external display is not waking, the Retina display flashes through different screen views, which only partially reflect my normal screen, or do not reflect my normal screen at all.Â
My sound keeps turning off. When I check the settings, the output device switches randomly between Internal and Digital output. I have no idea where the Digitial Output is coming from and this started about a month again. It switches randomly and then I loose all sound for a few seconds. Sometimes it happens once then stops for a few days, other times it switches back and forth for 5 min. No idea!!!Â
I just purchased a mac mini and I hooked up the vga cord, however there are two black bars on the left and right sides of the output (everything else is scaled fine but it looks like it is showing on a tube screen). What resolution/tweaks do i have to make in order to get this to fit my entire screen? I am using the typical VGA adaptor for output from the mac mini to the tv.
I'm looking to run video out to two TVs, but it's over a decent distance, so I'm worried that using an HDMI splitter would cut the signal and suffer quality loss. I was wondering if both mini DisplayPorts can be linked to output the same signal at the same time, so that both TVs can show the same thing but each signal is at full force.Â
Ideally I'd like to use both the ACD for day to day audio output, then turn on the external amp while watching movies and playing music, being fed by the optical out.Is this possible, or will connecting the optical cable stop all sound from coming through the ACD?
Alright so I go the new 21.5 inch and love it but I was wondering if the Mini-Display Port does audio for the HDMI output. Because if it did, that would be wonderful.
I've installed a Mac Mini (unibody) on a friend's boat and have the display output through the HDMI port througha distribution amp to 3 TVs. I have been having resolution difficulties though. When the display is output this way (split three ways) the resolution does not fit the displays, and there is no means to change it to a setting where it will fit the TVs. All TVs are full-HD and 1080p. The screen expands outside of the viewable area.
I use an external monitor with my macbook, it's a couple of years old 17" Sony TFT. I connect it to the macbook through a DVI cable into the adaptor, into the mini DVI port on the mac. About 90% of the time I do this, the second display shows the correct graphics but is tinted fluorescent green, however if I play aorund enough with the connection, it goes back to full colours. Is this something a genius could fix, or do you have any recommendations about what to do?
While using Google Sketchup and several other prgrams concurrently my macbook air cpu heats up substantiall. I like keeping the air "open" to allow for maximum heat disipation but of course this keeps the air screen on while I only want to use my external monitor. Is the only way to turn of the air screen turning down the brightness and using the "Mirror Display" option or is there another setting which alows my to utilize only the external display while the screen is open on the air?
As the title states. I am looking for an external display that matches the display on my black MacBook. I want one with the same gloss finish as my MacBook, this way I can calibrate both screens to look the same. That way when I switch screens it doesn't look different.
Anyone know of a screen that looks identical to the (previous generation) MacBook? I was thinking of getting a Samsung T240 but it has a different finish. How are ASUS screens? Any screens out there that have the same gloss finish?
I have a mac mini (solo intel) 10.4 OSX. I have no audio output when attaching an external input source like a CD player or ipod to the input jack on my Mac Mini. Audio output from ITunes or movies clips in IPhoto works fine. I have checked the cables and connections. I have checked the "sound" location in System Preferences to make sure the "built in output" source is selected. The input volume display shows that the audio input is being registered. I have checked "system profiler" in the Utilities folder in Applications to make sure the "built in output" AKA headphone outlet is recognized.
I have the "Soundflower" App. installed but turned off.
why the audio output from the internal sources like ITunes and IPhoto music clips work but the audio output from an external input source does not? Is there some software or a driver required for audio output from an external source that is not required for audio output from an internal source?
i'm hoping someone can help me out on this little problemmy usual set up is a pair of speakers connected with jacks via an m-audio usb audio interface, with an external monitor connected via mini-dvi to dvi.now for some reason my audio interface has randomly broken (on a side note, could a power cut have somehow broken a usb peripheral connected to my macbook whilst it was asleep?) so i've hooked up my speakers to the line out to rca. Now for some reason, when i plug the mini dvi connector into my macbook i get an incredible amount of hum. not just a little, alot!
I have Mac Pro with Digidesign/ProTools interface connected. I sometimes switch sound output from MP to run through the digidesign hardware. I'm getting message right now saying "selected device has no output controls", not allowing me to switch. I rebooted with the interface already turned on. I've run into theis before- can't figure out what causes this to happen. Sometimes it's OK. ?
