MacBook :: Can't View The Entire Screen When Connected To An External Monitor Via VGA Adapter
May 29, 2012
my screen cracked on my MacBook and I'm unable to see anything (it's just fuzzy white) so I purchased the VGA adaptor so I can connect to an external monitor. When I plug in the screen is zoomed to close and I can not view the entire screen. I can see one application that I have open, which is iMovie but can not see the top menu or my icons at the bottom. How can I adjust the settings seeing how I can not access the menu bar or anything else for that matter. It also appears to be showing a second screen, maybe not my desktop because the background is different. I'm running on OS X Lion. Â
I'm trying to finish an end of the year slide show for my kindergartner that I need completed today, I was five minutes away from finalizing then my two year old threw his monster truck at my screen!

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.

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.

I also looked about for this but couldn't find anything.Im currently using a 13" mac book (Which i love) But the monitor is sooo small for using programs like logic and reason ect at the same time. I need to use an external monitor for this. I know you can get an adapter for this but do you have to duel screen your laptop with the screen. OR (This is my question) Can you keep your macbook closed maybe on a shelf somewhere and still use your macbook with a keyboard/mouse and the external monitor?

I just got my Sammy HDTV/Monitor, which is a 23" 1080p HDTV. However, when I connect my MBP via my mini-displayport to HDMI adapter, the screen gets cut off on the top and the bottom. I have tried to switch the resolutions from 1080p to 720p, but it still does the same thing. It gets off both when I use the external as a secondary monitor and when I mirror the displays and use it as a primary monitor. When I turn overscan off in System Prefs, the 1080p image shrinks and there are black bars around all sides (however, it does show the entire screen). Does anyone know how to fix this? I want to get the most out of my recent purchase, and I know this is possible because I've seen it.

But is there a preferred brand of adapter to connect a monitor with a DVI port to the Mini DisplayPort on my 15" MBP, like Monster? Or what do you all recommend?

I just hooked the cable up, and I get the standard Purple Haze in space desktop that I have on my Macbook, but nothing else. No icons, no toolbars, nothing. The only time I was able to get anything to come up on my larger screen was when I went into Preferences, and Desktop and Screensaver. When I click on that, I did get a box to show up on my larger screen, listed as the Secondary Desktop.
How exactly do I get the larger screen to serve as my main screen? When I close up my laptop,the larger screen goes blank. I have no idea what to do, please help!
Another question I have is how the screen will look once I do actually get it to work. The reason why I ask that is because my larger screen is an old 17" Dell, the old 4:3 box kind. I plan on upgrading to a 20" plus HD display in the near future, but cannot at the moment, so the current 17" will have to do.
Anyhow, just curious if the screen is going to be completely wonky looking given the resolution that my Macbook will be feeding it?

Did any of you experienced this ? My WiFi slows down or even stops working when external monitor is connected (via the big connector, don't remember it's name, DMI or something like that). Air Rev A, 1.6.

I have a strange problem with a WiFi slowdown when connected to a TV. Here are the specs of the equipment:
2.2 Ghz white macbook, santa rosa, 4 gb ram, purchased January 2008
Panasonic TV connected via HDMI to DVI cable + Apple Mini DVI to DVI connector
USB Western Digital harddrive connected to a 500 GB Time Capsule (1st edition, no dual channels)
Snow leopard 10.6.1
Before upgrading to snow leopard, I would frequently use the macbook to provide video to the above mentioned TV streamed from a hard drive connected to an imac (connected to the same time capsule). I moved, and upgraded to snow leopard, and haven't tried this until finished setting up my equipment yesterday. I can stream videos to the macbook from this hard drive fine when nothing is connected. However, the moment I plug in the mini-DVI connector, the WiFi drops to a crawl. This applies not only the to air disk but any data from the network (internet, etc.)
A couple of additional notes: Display is set to mirror. Has nothing to do with clamshell mode because the macbook isn't closed. Nothing to do with location/interference- the effect is instantaneous with plugging and unplugging the cable. The base station is actually closer than in my previous setup and is pretty much 20 feet away in direct line of sight. I connect to another external monitor daily at work (vga, again with apple mini dvi to vga adapter)- no issue whatsoever restart did not help. I canceled all time machine backups over the network to limit that as a factor- no effect.

I bought a 22 inch monitor. its a pretty generic brand, but its very high resolution and works great on other computers. i got the vga adapter for my aluminum macbook (i posted in this section because its closer to the 13" mbp). i have an apple keyboard connected to it. i try to use it in clamshell mode and when i press a button on the keyboard to wake it up the screen just flickers as if its trying to adjust the resolution. strangely enough, it works perfect in mirror mode. anyone have an idea?

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.

I'm using a DVI->HDMI cable to connect my Powerbook to my Sony LCD TV. The Sony's native resolution is 1366x768. For some reason my Powerbook doesn't want to switch to this resolution. I can get 1280x720, but this leaves a black border around the images the whole time.
I've tried setting a custom resolution using the trial version of SwitchResX but to no avail. It won't do it.
Anybody have any similar experiences and possibly found a fix?

I searched the archives and I can't believe no one has mentioned this yet! This is a huge problem on both my Rev A and my new Rev B. When you connect an external monitor and external speakers using the headphone output, there is a high frequency ringing sound coming out of the speakers. I've managed to live with it by turning the treble to minimum and keeping the volume low enough but at the expense of sound quality. The strange part is, if you disconnect the monitor, the ringing sound stops. The problem only occurs if you have speakers and monitor plugged in at the same time. I've tried this on my Samsung monitor, my SONY TV, and my Panasonic audio receiver. The problem occurs with both Rev A and Rev B while my white MacBook and 2007 MacBook Pro all sound fine.

Is there an easy way to cause a connected external monitor to be "disabled?" E.G. I have an iMac connected to an LCD TV (via VGA, spanned, external at 1360x768). If the TV is plugged in, even if it's off, the computer switches to spanning mode. The consequence of this is that, if my preferred setup is to have the external be main, for instance, I essentially have to unplug it from the iMac whenever I don't want to be using it. Even if the external is the 2ary dsplay, it means that the mouse can go off the edge of the screen on one side, and that two of the hot corners are messed up. Is there any utility that could do something like add a "disable external display" item to preferences or the menu bar?

Recently, my quicktime (with Perian installed) stopped playing AVI files - giving me the whole 'The movie is in a format Quicktime doesn't understand' business. This made no sense to me as AVIs were playing fine previously. Nothing I did could fix the problem. HOWEVER, just today I plugged in an external monitor to test something out; lo and behold, quicktime is playing AVI files just fine again. What's going on?! Has anyone seen this behaviour before?

I have a 24 inch imac and i am connecting the viewsonic VG921m (19'') monitor using the mini-dvi port. The external monitor appears dull (whites have a yellow tint) Is there a way to match up the display to look like mac? I am using the monitor next to my iMac and its currently distracting as its displaying same colors in different tone.

I just bought a tv to use as a external monitor for my mac however when i boot into windows 7 the resolution (1080p) is fine but its not filling the screen completely, there is 1 inch of black on the top and bottom and about 1.5 inches of black on the left and right sides. it does not do this when i am booted into osx.
i think this could be because of how hdtv's are made and the resolution isn't exact (usually a little bit greater) so windows isn't "stretching" the image to fill the screen. i think osx does it automatically but windows doesn't. if this is the problem how do i get windows to stretch the image? i tried switching the screen mode on my tv's remote but that didn't work.

when I connect my macbook unibody with dvi to my dell monitor the quality of the screen is not as "good" as when I connect my windows pc to it. Is this only a problem on macbook, or is the mac mini the same?

I work on the macbook between 90min-2 hours throughout the day. At home, I hook up to a twenty-four inch monitor that I had calibrated through a Windows based system and complete my work. Now the files that I am working on are being processed through the macbook but viewed on the external monitor. I don't really care about the calibration of the macbook because the work that I am doing on it without the external monitor is really not color related i.e. removing scabs off of children, removing hair off of the face ect, but I need the final image to be accurate before it is sent off to the lab.
So, what do I need to do? Calibrate the macbook and the monitor or just the monitor and if just the monitor can anyone walk me through this? I know I could "search" but switching over from windows has been an experience and honestly, I am tired of "searching". Speaking of searching, I am still trying to figure out a way to sync my Dell x50v to the macbook, anyone? I know the x50v is old but it is the most solid piece of windows hardware I have ever owned and it still "just works".

I have a white MB (early 2008). I'm going to be getting an external monitor soon with a native resolution of 1920x1200 - the highest that the MB's Intel GMA X3100 will support. I know that I can open System Preferences > Display and then click the little menubar and drag it to the other monitor to make it the primary. Here is the thing: I want to just use my 24" monitor and not use the MB's screen with it (I have an external keyboard and mouse).
Should I...
1. Use the two displays as an extended desktop and then (leave the MacBook lid open) just turn the brightness on the MB all the way off so the screen is black (no back light)?
or...
2. Just close the MacBook and use it in clam shell mode? I watch Hulu and YouTube a lot which causes the CPU load to increase and fans to spin up.... do I have to worry about over heating? I would be using the 24" monitor exclusively all the time and then take the MB when I go to class. Will this just ruin my MB pre-maturely?

My 2006 mMcBook is dead and parted out. I still have the case and screen, but no HD, RAM, battery, or working logic board. How can I take the screen and make myself an external monitor out of it? I am presuming it's possible. I can solder a little and I love messing with parts from radio shack. So, has anyone heard of this? I tried googling it but couldn't find any search terms that brought me what I wanted.
Basically, I want to convert the video cable to DVI or even better, Display Port, and then figure out how to solder in a power source to just plug into a wall (since I'm assuming it'd be too big of a job to have it powered off of the FW800 or USB from the macbook pro). Is this possible? Since the computer is dead and gone, it won't hurt to experiment. Anyone have any links or guides to this?

My USB ethernet is "unplugged" (according to System Preferences/Network) after it's been plugged out and plugged in an USB port. The actual network connection doesn't work either. The machine needs a reboot to have the adapter connected. USB probing lists the adapter as expected after re-plugging.
