Connecting my mac to an external screen

Can anyone tell me how to connect my macbook to an externl screen?

If it is a Mini DisplayPort, be certain to insert the computer-end until essentially ALL of the metal end is inside the jack.
If you get any picture on the external display, it is working as intended:

You meant this? This is the first time I have ever heard of it, but I doubt that it is a scam.

There are other apps that "connect" an iPad to a computer, but those apps work over WiFi.

Connecting 2 Macs to an external hard drive

Hi,
I have an iMac G4 and a Mac Mini (with Panther on them). The hard drives for these two macs are running out of space due to a large library of music, video, and photo. I am thinking of getting an external hard drive and move all these to there.
My question is, am I able to hook these two macs to the external hard drive and access the file? Do I have to partition the hard drive into two so that each Mac will have its own partition on the hard drive?
Thanks, guys.

An external hard drive can be shared by two computers, but both computers can't be plugged into the hard drive at the exact same moment. However, if you have iTunes or iPhoto running on the one computer with the hard drive, you can share your music and pictures to the other one. You could also turn on File Sharing on the computer with the hard drive and then you could connect to the hard drive across your network to access or share other types of files.

Slow to connect to Mac share - file and screen

I have a few Macs on a network, with wired and wireless connections. I'm finding that I can connect to some of the machines quite quickly - from time that I click on the machine in the Shared area of the sidebar to when I see disks appear, or from when I click on screen sharing to something appearing, is fast. This is true for a PowerPC Mini running 10.5.x - takes 1 second for disks to appear.
At the same time, I have a MacBook Pro, 2.8 GHz, running 10.6.6, where it takes as much as 15 seconds for disks to appear or screen sharing to start. This happens with wired or wireless connections to the machine - I can be wired through a gigabit switch between that machine and another fast machine and still takes 10-15 seconds. This has been occurring for some time, and was present before and after the 10.6.6 patch.
Once I am copying data between machines, things seem to run quickly. So it seems mostly to be at the initial connection. If I go to sleep on a machine that is already connected to this MBP, wake up, then click on the MBP again, even though have mounted shares it still took 15 seconds to re-display the shares.
Any idea how I might diagnose and fix this?
Thanks,
Alex

There is no external drive on this machine - and I verified that the disk is awake. Not the issue.
The wired test was done between Macs on the same gigabit ether switch.
Another clue - I've found that when playing Starcraft 2 on this machine, this machine is the last to load vs others in multiplayer. I'm playing side by side with another machine on an older MacBook Pro, slightly slower, and that one always loads faster.

Mac not displaying External screen as HD

MacBook Pro not properly displaying HD resolution of 1440x900 on External monitor.
MacBookPro2,2:
Intel Core 2 Duo
2.16 GHz
OS X 10.6.8
PC External Monitor:
19" widescreen
1440x900
DVi and VGA inputs
Mac connected by VGA cable and Mac adapter. Have been using this system set-up for 2+ years without an issue.
Downloaded RED Camera software (R3D) to view the camera's raw files (https://www.red.com/downloads/), after install, Mac suddenly not displaying proper high resolution on External monitor. After some searching it appeared to be an issue for others, as suggested, I deleted all traces of the software, but after hard shut down and restart(s), Mac still doesn't output the correct resolution. I know it's the Mac's issue because the External display keeps displaying a message that the computer isn't sending the right resolution out.
In System Preferences > Display Preferences, the VGA Display (the External monitor) lists a slew of resolution options, and the closest resolution to 1440x900 it lists is 1400x1050, 60 Hz, unfortunately this is a stretched aspect ratio on the External monitor, all the other resolutions are too low, are stretched or the frequency cannot be displayed.
Called Apple helpline, and the technician couldn't solve the problem.
Not comfortable with using Terminal commands.
Some have suggested using SwitchResX to create a custom resolution and force the Mac to take it, unfortunately I cannot figure out what technical specifications to enter in the custom resolution cells.
Please help! Thanks!

Been doing some research on this TV. In HDMI, according to the manual on p18, it will only do normal or widescreen settings. Widescreen attempts to simulate 16:9. This introduces overscan with image clipping and artifacts on this TV model. A PITA that many are reporting. I believe, that if any HDMI testing is done, it is with Windows 7 PCs, and the internal firmware on the TV is calibrated to that. The other possibility is that the EDID signal sent upstream from the HDMI port isn't being interpreted correctly by the HD4000 or OS X.
If you venture into your Advanced Video Settings from your Picture menu, do you have an underscan setting there, or is overscan/underscan tuning available from the OS X display preferences for this HDMI connection? I saw an insignia post from 2010 where the HDMI video issues were resolved by setting underscan, but it doesn't describe any more detail. This was on a 2010 Mac mini with OS X 10.6.4. No mention what graphics adapter was used. The same post indicated that the same HDMI video feed was ok, when that mini was booted into Windows 7. A far cry from your new mini with the HD4000, but just maybe about that underscan...
If you purchased this TV less than two years ago, you are still under factory warranty, unless acquired under special sales terms, that modified that warranty.
There are four HDMI ports. Same results on all of them?
Don't have this TV here, so can't offer any hands on solution knowledge, if any exists.
Good luck.

Mac Book with Additional Screen

I have mac book with external screen. I have attached cables to screen and have power. How do I get screen from mac book to show on larger screen?

I wonder if you are asking how to get any image on your external screen at all (rather than how to make it mirror your MB). You did not say what connection you are using (VGA, HDMI or DVI), not whether you get any response from your external screen, but the first place to go is to the Displays panel in System Preferences. There, you should be able to see that the external display is recognized and you can select its resolution and position it in relation to your PB screen (or set it to "mirror") if wanted.

Resizing to external screen after using notebook separately

I read a lot of questions about resolution etc. when using an external screen, but I think my questyion has little to do with that.
I use an external 24" screen with my MBP 15" Retina. No problems there.
Once in a while I take the notebook out, like when going to a customer and open Mail, Safari, iTunes, etc. Still no problem.
But then, when I get home and connect the MBP with the external screen, all the program windows that I used with the notebook without external screen, are still the size of the notebook screen on my external screen. It's not a resolution issue, but I have to resize every single one of them to fit the screen size of my external monitor again.
What bugs me, I haven't seen this behavior in the Windows world, AFAIK the window automatically adjusts to the size of the external screen.
Here's my question: Is there a magic trick that works for the Mac similar as for Windows machines?

That error means that the Registry Files are corrupted - which is usually caused by faulty Memory.
Test the RAM for errors. You can use the free Memtest utility:
1) Go to http://www.memtest.org/#downiso and download the "Pre-Compiled Bootable ISO (.zip)"
2) Open the ZIP file and extract the ISO file to a temporary folder.
3) Burn the ISO to a blank CD using an "Image-to-Disc" or "Bootable CD" project in your CD/DVD burning software (dont use a normal Data Project).
4) Insert the Memtest CD into your laptop and turn it on, press F12 to launch the boot menu, and select "CD".
After replacing the bad RAM, you will need to run Recovery again, because the files have already been corrupted.

External screen turns green?

I've had this setup for a while now.. A 12 inch PB with a CRT 17 inch monitor connected to the PB through the "mini dvi to vga" adapter..
Now this is the problem: since a few days the image on my external screen is green.. It's not totally green, i can see pictures and programs but it's like the color balance isn't right.
First I tried to change this through display calibration -> didnt help
Then i tried to manually adjust the color balance through the screen display settings -> didn't help..
So I thought my crt monitor was broken. But then I connected my PB to another external screen trough my "mini dvi to vga" adapter. And I had the same green screen. Then I knew it wasn't my crt monitor that was broken but it had something to do with my output signal..
Fortunately a friend of mine has a nice 20 inch tft display. I tested the connection again with the "mini dvi to vga" adapter and got the same green screen. But then I connected my PB to his 20 inch screen through a "mini dvi to dvi" adapter and the green was gone! So it couldn't be the output singal of my PB..
So i figured my "mini dvi to vga" adapter must not work properly somehow. I don't know how it could have broken. It happened just like that. I turned off my PB, and when I turned it back on the external screen turned green. I didn't do anything weird with it..
Could this be? That the adapter is broken? Or do you guys think there might be something wrong with the output signal after all?
Anyone encountered something similar?

So I went to an apple store today, and explained them my problem. We tried a new "mini-dvi to vga" adapter but still the external screen was green!! Also, when using my adapter that I supposed was broken on another PB the output singal was perfect! So as it turns out, it's my PB thats not working properly..
The guys at the store said it must be somthing with the motherboard.. I just don't think I can miss my PB for more than a few days!! :P

Shattered screen, external screen in standby with Satellite A10-S203

The screem of my Toshiba Satellite A10-S203 is shattered, it is all tripes, colors and black spaces. I connected the laptop with an external screen, but as soon as Windows starts the external screen goes on stand-by. How can I change this?

Hello,
I have had this issue as well before. After Windows starts the video is reset resetting the video output to LCD instead of external monitor. Once this happens try using Fn+F5. If this does not work, you might be able to boot up and press F8, once it gives you the windows selection menu go to safe mode. Once there go to video properties and change the default settings to external monitor, and try rebooting normally. Should work wonders. Hope this helps, if not let me know.

It appears what happened is the installer though it was looking at a empty drive and just went ahead and installed.
I of course am assuming here you didn't use Disk Utility to format the drive first before installing, that would wipe out your files and programs for sure.
So what to do, what to do.
Well there is hope for you as long as the drive wasn't Filevaulted.
I'll explain. When a hard drive writes data for the first time to a drive, it starts at the very top and works it's way down.
When OS X was installed the first time, it was at the top of the drive, unless you upgraded then the upgraded OS X could have been written elsewhere.
Now when you just reinstalled OS X, the new OS went on the top of the drive, overwriting any data that was there previously, so what was there you have lost forever which is about 8GB or so. If it was the previous OS there, then your more in luck because only the old OS X was overwritten.
The remaining space on the drive still can have a copy of your files, provided it's not overwritten yet.
It's because when a hard drive deletes data or reformats, it doesn't remove the data off the drive or overwrites it immediately, it's just made so it's SPACE is available for new files to be written there.
So technically one can recover the deleted data off a non-encrypted/scrubbed hard drive with special software.
The way it does this is it reads the 1's and 0's of the files themselves, and through a lot of figuring out, can tell what that file is and what it belongs too.
So what you will have to do is this:
Create a data recovery/undelete external boot drive
or if you don't have the skills, then take it to a local PC/Mac tech and they can do a direct image of the drive and then you can run Data Rescue on it to rebuild your files.

Go to your "screen settings". then chose "find screen" then you vill find the prosjector.

I am trying to connect my mac book pro to the tv via a mini display port and a hdmi cable, the only picture that is on the tv screen is the background picture on my computer, any suggestions?

I am trying to connect my mac book pro to the tv via a mini displayport to a hdmi cable, the only picture on the tv screen is the background picture of my mbp, does anyone know what I need to connect to my samsung tv ?

Hi there. I also bought an iWires mini Display port to HDMI cable and have an LG LED/LCD TV. I plugged it in to my MB Pro and followed the very small writing that came in the package and got both audio and video going. You need to change the audio settings from within System Preferences on your Mac to select your TV as the audio output.
My concern is the data latency - do you experience a delay between moving your mouse on the MBPro and the TV displaying the movement? It is only a fraction of a second, but certainly enough to be annoying, especially in a cable as expensive as the iWire.
