I taught two terms at the university using my MB Air 2012 with a VGA projector. Each time I connected the Mac to the projector and took it off, there was random noise on the display. I considered it as normal. Now the lessons are over and I don't use the projector any more. However, every time I turn on the Mac and when I shut it down, I see the same noise on the display.

I love my MacBook Pro -it's used all the time in schools, without hassle.
However, when I try to connect to a Sony VPL ES1 data projector, the screen resizes (normal and OK) but the data projector shows a completely different desktop image and I can't see a cursor.
Presume this is a bug, but is there a work-around I'm missing?
I'm having difficulties connecting my late-2013 retina display Macbook Pro to my Viewsonic PJD5223 projector. I have a (working) HDMI to VGA adaptor as well as an HDMI to mini-displayport/thunderbolt adaptor, and I have tried using two methods to connect:
1. Using he HDMI port directly
2. Using the thunderbolt port through the HDMI/thunderbolt adaptor on the Macbook Pro
Neither method appear to working. My Macbook Pro screen begins to blink/flicker, as if connecting then disconnecting rapidly. During the quick flashes, sometimes I can catch a glimpse of successful connection to the projector because the display settings panel for multiple screens appears.
I know that my adaptors are working because I can connect my Macbook Pro to my HP monitor with either of the two methods. I can also connect my PC to the projector using the HDMI/VGA adaptor. The problem appears to be specific to the retina display Macbook Pro or a more recent software update because I can connect to the projector using an older 2008 non-retina Macbook Pro.

Have new MacMini... need to connect both a display VGA and a separate digital projector but there is only the HDMI to VGA port. Could I use the Thunderbolt port for that purpose, and if I can, do I need a special cable and connector to VGA?

I recently hooked my mac laptop to a display projector, and now when I log off or shut down the screen resolution reverts to a stretched view. I reset it to 1280x800 in System Preferences-Display, but it keeps changing back. I'm running OSX 10.5.8

I have noticed something strange that occurs occasionally on my MBP (i5, latest gen). The display seems to have "noise" in the quality of graphics. It's hit or miss when it happens, and a reboot stops it temporarily. It returns after a few days.
I'm going to the Apple store today, but thought I'd see if anyone else has this issue. I am a little touchy about MBP graphics (had issues in the past
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.
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.
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?

I just got my 2.0ghz Alu Macbook a few days ago and everything works perfectly well, the thing is that after day one the magsafe started to emit a low pitched electrical whistling noise. It tends to be there a few minutes after booting into the OS and then it turns down to almost unhearable, but I experienced it returning after a few hours of use and then disappearing again. If I move close to the escape key I can hear a crackling noise emitting from the magsafe.I'm not trying to be overly nitpicky or anything but I read somewhere that if it's doing that it would be a faulty Mag-Safe board or something.
Does any one you guys know anything about this? I have the 14 days to return it as I bought it online from the Apple Store so if it's a faulty part that might die/break/ cause problems later I might have to.
Sometimes I lift and carefully move my 17-inch MBP a short distance to another flat surface without putting it to sleep mode, it starts making really loud mechanical noise when I put it down, so loud that people in the same room can hear the noise and I can feel vibrations too! What causes this? Where does this noise come from? Is my MBP defective?
View 3 Replies View RelatedMy first generation unibody Macbook hasn't had any problems to this date but now it's constantly making that mechanical loading-like noise which is usually heard when the Macbook is switched on (the noise before the start up sound) or when the lid is opened to wake up the computer. Is there a fix to this?
View 5 Replies View RelatedOn my 13" MacBook Pro, the hinge makes a cracking noise on the right side of the computer (near the power button) when the screen is positioned all the way back.The entire hinge also makes a loud popping noise when I adjust the screen position. The screen seems very tight, and it takes a little bit of effort to move the screen, and when the screen is moved it makes the loud popping noise.
This is probably going to make some of you guys cringe, but sometimes putting pressure down on the top of the case close to where the black hinge meets to unibody enclosure seems to stop the popping noises. Putting downwards pressure on the hinge, or flipping the computer over and putting pressure on it that way, also seems to alter how much popping noise there is.
If I mess around a bit with applying pressure on different parts of the computer around the hinge, I can usually eliminate the noise. But, the cracking noise when I put the screen all the way back is still there.Any ideas what to do? It's not interfering with the operation of the computer, it's just incredibly annoying and this is only a four month old machine which shouldn't be creaking and cracking already.
Has anyone else had problems with an old G3 Pismo making an annoying squealing noise when plugged into a charger? There's a lot of noises mentioned in mac/apple forums but none of them relate to this one. Here's what it is not:
It's not coming from the screen or the fan or the speakers (it's under the keyboard). It's not low or slightly annoying (it is a loud squeal). It happens only when the power adaptor is plugged into the laptop.(it used to cease after I unplugged the power adaptor and plugged it back in three times; now that solution doesn't stop the noise anymore). It charges ok, and runs ok, scream or no-scream. It's quiet right now, but if I move the adaptor to another plug it will start again.
I was going to live with this, but today after an hour of operating quietly it just started again, and I hate to leave the house with this going.(it will scream whether the laptop is on or off. I have a really old battery and cannot replace it (I am currently staying in Mexico for the summer). Battery life is 45 min. I haven't tried pulling the battery out. That would be too easy.
This all started when I bought a replacement power adaptor (generic),after the original one melted down, but I could stop the screaming by unplugging/plugging it in again once or twice. Then I bought an expensive iGo adaptor, and it does the same thing.
I Did the PRAM and PMU reset.I can hear it over music or the tv. It grew lower in pitch today after squealing for a half hour. I'd normally not let it go on that long, but i was

I just got my macbook pro yesterday and ran it all yesterday not hearing anything. Today when I woke it from sleep I could clearly hear the fan or hard drive going. I was in a quiet room and it's quite annoying.
istat says its at 2000 rpm so thats when I started thinking it may be the hard disk. It does pulse every now and then but thats even while it's just sitting idle.
I guess I could live with it but its just annoying. Anyone else having this?

I am having the following problem when connecting my macbook to my new Sony projector.
The projector is only showing a portion of the computer screen. It seems as if the computer is dividing the notebook screen and the proyector and I can move objects between the two screens. Its like having two displays.
But i dont want this. I just want to have the projector show exactly what the macbook is showing on its screen so that I can watch movies.
How do you connect the air to a projector, what cable do you need.

has anyone attempted to hook the brand new MBP Unibody to a projector?
I saw many problems to hook it to an external monitor via VGA or DVI adapter... has anyone attempted it? Is it possible?
I have a presentation by the end of the month and I need to know if I can do it on my Mac with Keynote or have to go with the craptastic Power Point.
What type of adaptors do you need for the new Air to be sure you can use it on all types of projectors?
View 6 Replies View RelatedI am looking for some suggestions for a projector that will run, and hook up smoothly on the Air. I don't need top of the line, but maybe around $700.00 is in the budget so far. I want to be able to show keynote presentations, website demos, and maybe some shorter video clips as well.
PS: I did some digging and wondered if the Optoma EP7150 was a good bet. The street price is around 800.00 (but I found a few that were around 500), and there is a newer model out now so the price should be dipping). 2.8 lbs, 2500:1 contrast ratio, 2,000 lumens... and XGA output. Anyone have any experience with this one?
I have a MBA (my first apple since the Mac SE 20... ha!) and I have a Dell 2300 multimedia projector. I have the DVI-VGA adaptor, but I can't get a good picture to project. I've toyed with the display settings to see if I can get it to improve. The picture stays dark, or blurry, etc etc.
Is there a setting I'm missing, or could I maybe have a bad adaptor?
I am getting a Pico Pocket Projector. Unfortunately, it doesn't offer a vga port and the only way to connect anything is through composite. I was thinking of using VGA to Composite and purchased the following:

I had my new mbp connected to an LCD projector for class the other day. At the end of class I disconnected it and put it in my bag. When I got back to the my office I took it out and it was burning hot everywhere. I opened it up, there wasn't a response, but it eventually restarted. Everything seemed fine. Since then, I have connected it to the tv at home a few times to watch some shows, and the exhaust gets going at a fairly high rate. I never noticed the sound of the fan before, but iStat says its going at 6200+ rpm and its quite loud. It doesn't really feel hot. Anything to worry about or am I just being paranoid about my new baby?
View 2 Replies View RelatedLooking to connect your Mac notebook to a TV, projector, or sound system? Here's a quick guide that outlines all the things you need to make it happen - from adapters to cables to ports. Just follow the simple instructions to verify that you're getting exactly what you need. And remember, just because you setup the video side of things correctly doesn't mean you're going to get audio. If you want both video AND audio, make sure to also follow the directions indicated in the "Audio" portion of this post. VIDEO Check the ports on the back of your TV or sound system to see which of the following options are available to you. Find the port that matches below, and you're set! Remember, if you also want audio, check the "Audio" section at the bottom of the post. If you want to use composite video and you're using a MacBook (white, purchased after fall 2009), you need this adapter + a third party converter + a VGA cable + a composite (aka "RCA") cable. Aluminum unibody (black keys, purchased after summer 2009) MacBook, MacBook Air, or MacBook Pro, you need this adapter + a third party converter + a VGA cable + a composite (aka "RCA") cable.
