Upon rebooting my left and right external monitor on my Snow Leopard Macbook Pro switch sides, right to left.

I'm using two plugable UGA-2K-A ( http://plugable.com/products/UGA-2K-A/ ). They work great for USB graphics, but how can I stop the configuration changes?

I found the solution to this problem on another website, tried it and it worked!!!
10.6: Re-enable LCD font smoothing for some monitors
Mon, Aug 31 2009 at 7:30AM PDT • Submitted by astrosmash
There is a bug in Snow Leopard that disables LCD (sub-pixel) font smoothing on many third party LCD displays, including models from Dell, Samsung, LG, HP, EIZO, and Lenovo. Here are the details:
Snow Leopard introduces simplified Font Smoothing options under the Appearance pane in System Preferences. Prior to Snow Leopard, the available options were:
Automatic - Best for Main Display
Standard - Best for CRT
Light
Medium - Best for Flat Panel
Strong
In Snow Leopard, you can only choose between Automatic and Standard CRT. Since few people use CRTs these days, most users now have only one option: Automatic. The problem with the Automatic option is that OS X incorrectly detects many third party LCD monitors as CRTs, and consequently, disables LCD font smoothing.
You can force OS X to use LCD font smoothing on all displays with this Terminal command:
defaults -currentHost write -globalDomain AppleFontSmoothing -int 2
The number 2 here corresponds to Medium - Best for Flat Panel. You may also use 1 for light smoothing, and 3 for strong smoothing, as per the original OS X font smoothing options.

Getting an Acer external monitor to work with a MacBook Pro

I just made the switch from PC to Mac and while I'm excited I'm having a few growing pains. Here's one thing I'm trying to figure out.
Both at home and at the office I have external monitors configured. These worked well with the PC but I having some problems with the Mac. I get the screens to work together fine (i.e. I can drag things from the laptop screen to the external monitor). However, the resolution on the external monitor is grainy. I've tried all the resolution setting and can't get it to work any better.
The Mac is a MacBook Pro with a 15.4" screen and the external monitor is an Acer AL2216Wbd.

two possibilities>
1. you're using analog cable to connect to external display (via dvi to vga adapter-but that is not the case obviously, because otherwise you could set the ref. rate for 60 or 75Hz - now its greyed out) anyway, when I used this set up, I noticed huge degradation of displaying quality. kinda washed out and blurred. but not grain at all
2. but what is more presumable in your case, you're using photo background provided by apple...these pictures are grainy by themselve. and when you extend your desktop from 15" to 20" it's clear that you notice it, all the more, if the external is not widescreen, therefore background image has to be stretched and cropped even more, therefore the grain is even bigger. This is my personal experience.
try to test it. put to the background for example some gradient made especially for that purpose in ill or ps. make two versions for both screens.
thats all
good luck

Network C7280 through Mac Time Capsule with iMac Snow Leopard, MacBook Pro S and Compaq W7

The HP works fine with the iMac desktop, but the 2 laptops won't print, although they seem to be recognizing the network. Says printer not connected. The HP Photosmart C7200 Wireless Network Test Report and Configuration Page seem to be normal and functional.
This question was solved.

If you are using Snow Leopard or Lion and have HP software for pre-Snow Leopard (either from a CD not marked as compatible with 10.6 or you recently upgraded to Snow Leopard and had the HP software on your Mac before you upgraded - even if you did a standard uninstall of the old software or installed new software over the top of it) you must uninstall the software using the 'scrubber' option:
Go to Applications/Hewlett Packard/ click on HP Uninstaller
Click on Continue
Highlight your device on the left pane
Hold the Ctrl, Opt and Cmd keys and click on Uninstall <<<< Scrubber Option
There will be a pop up that asks if you are sure you want to uninstall ALL hp software. (At this point, if you continue, any HP printers you have installed will need to be reinstalled)
Click Continue and let it finish
Restart your Mac
Now reset the printing system:
- Sys Prefs, Print & Fax
- Right (control) click in the rectangle listing your printers and select Reset Printing System.
WARNING - this will delete ALL of your printers!
- Select the plus sign to re-add it. Look for the printer, select it and wait until the "Add" button becomes available. Click it.

I've connected my external monitor (LG) to my new Macbook Pro 15" laptop, using the adaptor for VGA...the display now has a large black bar along the left side. No adjustment on the monitor will fix it, no "options" on System Prefs either...any ideas?

I've just purchased a new Macbook Pro, and connected it ot my external monitor (24" LG HD) using an Apple VGA adaptor. The only resolution that looks good is the 1920 x 1080, but the image does not entirely fill the screen. There is a large black gap on the left side of the screen now. It worked fine with my "last generation" Macbook Pro...no adjustment on the monitor will help, and cannot find any System Setting in displays such as "options" or widescreen setting. I've gone to the LG site, but no "Mac" related tech support issues come up...no forum here seems to deal with this particular issue either...any ideas?

I have the same thing but with a 23 inch HP, worked fine with my MBP 13 from 2009 but the 2011 2.4 i5 does the exact same thing as yours!
Very confused and hoping that some one else can help.
Thanks

External monitor resolution in Vista on MacBook Pro

I am running Vista Ultimate on a MacBook Pro. I have a Dell 24" external monitor plugged in, which supports a top resolution of 1920 x 1200. But Vista thinks it's a generic non-PnP monitor with a top resolution of 1024 x 768. I have installed the Windows drivers from my Leopard disk, but neither the Vista Displays control panel nor the nVidia software think the resolution of this monitor can go any higher. I tried looking on nVidia's site for newer drivers, but they said for the M series video cards to go to the computer manufacturer for drivers because they modify them for power consumption and other special needs.

I found the solution.
Go here:
http://www.laptopvideo2go.com/forum/index.php?showtopic=17701
Click on Driver to download it.
Extract it
Go to
http://www.laptopvideo2go.com/forum/index.php?showtopic=17701 again
Click on Modded INF to download it.
Copy it to the extracted folder.
Run setup.exe
You now have full control over your nvidia card. Which also means you can plug in external monitors
Tested on Macbook pro 15" with nvidia 8600M GT.

HT3131 how can i connect 2 external monitors(VGA) to my 2007 macbook pro

I would like to use 2 external monitors simultaneously with my clamshell closed. I have external keyboard and mouse but need to know how to and what to buy in order to achieve this.....havent found anything straight forward on apple site, like a vga dual monitor splitter, so am in need of some advice on how to do this please!

Thanks for the reply. Haven't gotten anything as yet. Just that I burned out my older PowerBook using it as a primary screen w/ a secondary 20" monitor. Would be nice if the MacBooks could be used as a CPU only, connect 2 different monitors, and use the LCD screen when portability is needed. But I suppose that is why Apple makes different types of computers. I know I can rig the video SCSI cable to bypass to LCD screen and use the other built-in monitor. But there goes the warentee and any kind of AppleCare... not that I have ever used it, (until a day after it has expired!)
But thanks for the feedback. Your reply is what I expected. Being that I am a mercenary graphic designer and need to be able to work whenever, and where-ever I need to, the MacPro is not my hardware of choice. As well, I don't have $4000 in my budget. But man do those machines rock! Just think of what NASA could have done with one of those in 1969 when we were going to the moon! But now that the U.S. has decided that manned space travel and even scientific space exploration is not worthy of having a budget, the MacPros are religated to creating new episodes of Jersey Shores!
Thanks again for your feedback!

Can't connect external monitor to Windows 7 bootcamp Macbook Pro 15 - ATI 6770

I recently puchased a Macbook pro 15 in 2012. I have bootcamp set up and am running windows 7 home on the bootcamp partition. When in windows I am unable to use an external monitor or overhead projector. I have updated all of the ATI drivers and have fiddled with screen resolutions and display refresh rates to no avail. I am using a cheapo mini displayport to VGA adapter which I have confirmed works while I am using the mac side of the machine.
Unfortunately I have to use windows while at work and using a projector to display data is essential.
I am out of ideas at this point -- Help - - Please!!

I was hoping some of the multi/monitor people would show up and help you but I guess they missed it.
Have you gone into the Properties of the video drivers (via the Device Manager) and let it Update Driver either through the internet or migrate to the newer Boot Camp video drivers you recently downloaded?
The only other thing I can suggest is to completely delete the video drivers then reinstall them manually either through the Programs and Features control panel or in the Device Manager/ Video drivers and see if it "takes".
Don't forget you do have an Apple Software Updater in Windows also. It updates the Windows support software from Apple. (Boot Camp)
Sorry I can't help more........

SNOW LEOPARD - macbook pro with external monitor

My external monitor (Formac DVI) is giving me problems since snow leopard - if I start up and close the lid the external monitor goes black with thin grey lines. I have to keep the lid of the laptop open until start up is complete and the desktop appears on both monitors, then close the lid, let the comp go to sleep then wake with my bluetooth keyboard that's very annoying.
What are the chances this issue will be fixed soon?? I may go back to Leopard for a bit.....

External Monitor RGB Noise Flickering with MacBook Pro

Hi folks,
I recently bought a MacBook Pro and plugged into it an HDMI converter to DVI, so I can plug into the MBP the LCD Apple Cinema Display of 22" and have 2 monitors working or, just one while using the hardware of the MBP.
The MBP has 8 GB of RAM of 1333 MHz and an additional ATI video card of 1 GB.
So, when working with the Apple Cinema Display plugged into the MBP, some kind of fast graphic anomaly occurs, which looks like an RGB noise. And that happens in a blink, each about 5 to 10 minutes and only in the Apple Cinema Display.
I'm wondering why happens this, because I need the big screen to work. Also, the MBP costs me a lot of money (US $4000 because I live in Argentina) and we don't have here the easiness to go and buy another or change the product because of a "just in case" thing due many other implications from the actual government.
So please, let me know why this happens and if it's dangerous. I don't wish my hardware get broke because I use it to work an there are no replacements here.
Thanks,
Ø3

I ended up buying the HDMI cable and adapter for the mac and the screen quality is GREAT! It auto sets itself to 1080p. Don't use VGA. Get the HDMI cable and adapter.
Again, the horizontal lines are from me taking a picture of my monitor from my iphone.
I hope this solves your problem.

External monitor/display for a 2012 MacBook Pro?

I want to know if I can connect an Acer S201HL to a 2012 MacBook Pro i7 2.9GHz 8GB memory OSX10.8.1 - I will be using a magic mouse and apple wireless keyboard as well - if this setup will work what specific cables and adapters do I need to get? If at all possible I would consider running 2 displays. also running Parralells with Windows 7 Home Premium.

With athundebolt diplay there might be some info here that might help.

If you have a mini DVI port you would need a moni DVI to VGA adapter, and a VGA cable

File Sharing between Snow Leopard MacBook Pro and Mac OS 8.6 Powerbook 1400

well ok, for some this might sound ridicule. Why should I still be using a 13 year old PowerBook. Let me tell you, this is writing/typing heaven, Zen-like; no distractions at all, no twitter, no internet (although possible), no emails just pure you and your text and if you spin down the HDD, absolute silence. as said before pure Zen writing heaven. and on top of that you're typing on the best keyboard ever on a laptop.
As you might see I love my vintage masterpiece of a laptop and use it on a regular basis. Just one Problem.
Since I Installed Snow Leopard on my MacBook Pro 17" I just haven't been able to establish a connection between the two machines.
I have to admit, I'm not that versed with OS 8.6 but with 10.5 I had absolutely no problems accessing the shared folders on my MacBook Pro and vice versa.
My first thought was to activate Appletalk on the ethernet on my Macbook, which I failed to find anywhere. The Apple Discussions Forums revealed that Appletalk has been dropped with the introduction of Snow Leopard but all the entries where regarding printing issues with shared printers, I didn't find anything about actual file sharing and thus did not get any clues how to share files between my two machines.
My PowerBook 1400cs/166 runs on 8.6 and I use a Global Village Platinum PCMCIA card (modem and Ethernet combi card). this setup worked perfectly with 10.5 but I have not been able to make establish a connection since running 10.6 on my MBP.
I am really desperate since I heavily depend on being able to exchange files between those two machines through an ethernet connection.
So I kindly ask anyone who might be able to help me to please consider posting any solutions or at least ideas which could help me with my problem. I really would greatly appreciate any effort whatsoever.
Thank you very much for your time.
EDIT:
What I forgot to mention: strangely enough, when I enable Internet Sharing on my MacBook Pro (through Airport) to Ethernet, my PowerBook 1400 can connect to the internet without any problems.
Message was edited by: Apolloss

First of all let me thank you very much. It actually works (partially).
There seems to be a problem though. While I can connect perfectly from my MBP 10.6 to my PowerBook 1400, the other way round doesn't work.
My MBP does not show up in the Network browser of OS 8.6 but I could life with that.
The problem is that if I try to connect to my MBP from my PB1400 by entering the IP directly a alert message appears reading that the "User Authentication Method required by this server can't be found, please check the AppleShare folder in the Extensions folder and try again".
Do you have any clues what I'm doing wrong or where the problem may lie?
PS.
Even if you may not be able to further help me with this problem, I ow you a great deal of gratitude and am very thankful for your help so far. At least I can exchange files between the two machines and that's what I needed in the first place.

Run two monitors from my 15-inch MacBook Pro (Non-retina, mid 2012)?

I'm looking to run two monitors from my 15-inch MacBook Pro (Non-retina, mid 2012). I don't want to use the actual laptop screen in this setup, I just want to use the two external monitors.
My 15-inch MacBook Pro (Non-retina, mid 2012) has the following ports on the side:
FireWire 800 port (up to 800 Mbps)
Two USB 3 ports (up to 5 Gbps)
Thunderbolt port (up to 10 Gbps)
I currently use the Thunderbolt port to one external monitor.
My question is: Is it better to run the second monitor via USB 3, or FireWire (if that's even possible)? What would you recommend?

See -> http://www.matrox.com/graphics/en/products/gxm/dh2go/digital_me/.
Good and simple way to get two monitors from one Thunderbolt port.

X240 (Win 8.1) w/ Ultra Dock and two external monitors connected via DisplayPort problem

I'm having trouble making this combination work. This Ultra Dock does have two DP connectors, computer sees both external monitors (HP ZR24w) but I cannot get any picture on both at the same time using DP. Sometimes one display does work, but that is not always working.
When I connect same monitors via VGA/DSUB and DP (with Lenovo DPtoDVI converter) I can get this to work - both same time - , but I'd prefer them both digital and both native DP as both monitors do have that port.
Ultra Dock does already have the latest firmware and this problem seems to not relate to the flickering problem with T440 etc. X240 is also running latest UEFI/BIOS and I've also tried latest Intel Beta display driver, no effect.

Minidock Plus Series 3
Two Asus monitors attached via DVI
Let me start by saying that the internal and both external monitors work simultaneously. However, getting to that state is the problem.
I can boot successfully with the laptop in the dock with 1) just the internal monitor, or 2) the internal and one external monitor connected.
However, if I try to boot with both monitors connected via DVI, the following happens:
Windows logon screen appears -- but there is no cursor on the screen
I enter the password and the login continues for 30-60 seconds, then
Blue screen SYSTEM_SERVICE_EXCEPTION for nvlddmkm.sys with STOP x0000003B
Lenovo has replaced the dock with no change in behavior.
Drivers and BIOS are current.
Most recent change was to set BIOS so Win 7 automatically detects Nvidia Optimus.
At this point, my best workaround is to disconnect one external monitor whenever I need to reboot, and then connect it again after everything is runing. Not terrible... but it really shouldn't be necessary. Any suggestions?
If you want to drive the monitors in the manner stated, the BIOS Display property must be set to Discrete and the auto detection below it must be disabled.

HT5019 MacPro laptop display and 2 external monitors (three displays). Can I have more than one application displayed at a time?

I would like to have my MacPro laptop display and 2 external monitors (three displays). Question, how can I have more than one application displayed at a time? IE: I would like email on one monitor, Finder on my laptop, and iTunes on the other. Possible?
With extended desktop, it appears that I can only have one application presenting at a time. Sort of defeats the purpose of having multiple displays.
I am using the HDMI and the mini HDMI connectors.
