External monitor and wireless issue

hi. i have a white macbook (2.0 ghz core 2, 1 gb ram, 10.5.6), and it's been having lots of issues recently: the fan won't stop running, it won't sleep, and the hard drive crashed and had to be replaced. before and after the hard drive was replaced, when i would connect the laptop to an external LG monitor, the wireless wouldn't work. the connection would timeout whenever i would try and connect. this is a fairly recent problem, as it worked fine for a year. restarting the monitor, the laptop, and the router don't help. the only thing i can think of is that it's not working because the laptop isn't sleeping properly--the fan keeps running hard when it's closed and connected to the monitor. still, the other functions work fine when connected to the monitor. if anyone has any suggestions, i'd greatly appreciate them. thanks.

It's possible you're infected with some type of malware. This theory would be supported by the fact that the problem went away, at least for a while when you reformatted, and many times the same malware infection will repeat for the same user who exibits the same behavoir.
A simple test would be to burn and boot from a Linux LiveCD, try using the Linux operating system and see if it exhibits any of the same problems, if it does, then you're likely looking at a GPU issue which would be serious. If it runs fine under linux, then I'd suggest you reformat and install windows and either be more careful about what you do online, or get some better protection.
There are many Linux distributions you can use, one of the most popular that works well with thinkpads is Ubuntu (ubuntu.com). Boot with the option to not make any changes to your computer. This will run the operating system solely from your cdrom drive, performance will be slower, but the point is we want to know if your graphic hardware is working properly or not and this is an easy test.
Good luck, and I hope your problem is only related to software.

MacBook Pro with external monitor and keyboard.

Hello, everyone.
I've tried to find the answer for this question but haven't found a clear answer with my Google search.
My older Powerbook G4 will not allow me to work with an external monitor and keyboard with the screen in a closed position. I am about to purchase a new MacBook Pro and would like to be able to use it at home with a larger monitor and keyboard but with the lid closed and its built-in screen turned off. Can this be done ?
How can a MacBook Pro be used (turned-on) with external monitor and keyboard while the lid is closed and the its screen is off ?
Thank you in advance for your answers.
Joseph

Hi Niel,
I have the same problem with my MacBook and I followed the instructions you posted. My issue is that when the computer wakes up after clicking the buttons on the keyboard it then quickly goes back to sleep. I can't seem to keep it awake when the lid is closed. I've been searching for an answer without any luck. Any idea how to solve this problem?
Thanks!
P.S. After I finished posting this message I figured out my problem. While fiddling with my computer and monitor, I inadvertently disconnected the power. After reconnecting the power, I was able to wake my computer and keep it awake. A note to other people having this issue: the computer must be connected to a power outlet to run in closed mode.

No video when using external monitor and resuming from sleep.

I know some people were having problems with the new MacBooks, but I guess the Mac driver fixed something. However, when I'm in Windows and have my Dell 24" hooked up to the Mini DisplayPort -> DVI adapter, I cannot resume from sleep. The monitor will turn on, but I can't get an image on it.
In MacOS it seems to resume from sleep fine, but not in Windows. Anyone else seeing this?
Thanks!

Is no one else getting this error? Does anyone have any issues when their MacBook is hooked up to an external monitor and it goes to sleep?

External Monitor Not Supported Issue (Sony Bravia)

Lenovo Community
I have been tryign to connect my Lenovo T400 to a Sony Bravia (KDL-32S300 LCD Digital Color Flat Screen) and unable to use the "Projector Only" (to watch recorded movie) video output setting. I am given a non-supported error. Yet I can use either the "Duplicate" or "Extended" video output setting just fine. The Sony Bravia even works fine with a more recent Lenovo T520. I also connect my Lenovo T400 to an older Smsung SyncMaster 930B as an external monitor and that works fine in the rojector" mode too. Can't figure this one out.

Are you using the latest available drivers?
Do you have an HD3470 switchable or just the integrated GMA4500?

FCP Problem with Firewire output to external monitor and speaker ???Help

i have a g5 powermac. the problem is when using Final cut pro 4hd. when i output my work through firewire to my external monitor and speaker i have a problem with the audio signal. Theres feedback/noise/hiss from the speakers. The firewire connects to DSR-11 vtr deck which feeds my monitor and speakers. it only happens when in FCP is set to A/V firewire output. does not happen if Video output is not set to firewire.
I Diagnosis is that it is not my dsr-11 deck or firewire i've ruled those out. The problem is either FCP software or Hardware problem with my G5
Does anyone have a similar problem. please respone, i will try to answer any respones,
Thanks
powermac g5 powermac

CaptM
From the firewire that feeds the dsr-11. on the output, i use s-video cable to my monitor (sony pvm-14l) and High Quality rca cables thet feed the audio to the Roland Speakers.
I've changed all wires and still have audio problem. I,ve changed my Dsr-11 deck to my camcorder and still have the problem.
If any of u guys use FCP The problem happens When I select view> external Monitor > and select firewire for Audio/ and video. I have never changed my editing habits, something just went wrong with the signal, I think its a Hardware problem with the firewire connection. I'm Going to have to bring this to a Apple Service Center In my local area one day.

Using the MacBook Pro with external Monitor and Keyboard

This may be a dumb question, but here it goes anyway:
Can I use the MacBook Pro with an external monitor and a bluetooth keyboard and mouse without having it opened all of the time ?
I am planning to buy a MacBook for my wife and most of the time she will be using it at her home office.
I don't want her to use the computer opened all of the time when she is actually looking at the separate screen and using a separate keyboard. Having the laptop opened will only accumulate dust and reduce the lifetime of the built in screen.
What I would actually need is a kind of "docking station", but Apple doesn't make that - I know.
So can the MacBook at least be operated without the internal screen powered on while it is closed?
Thanks for your help

Using the GT70 with external monitor and lid closed

I wasn't sure where to post this question.
I have several laptops and use external monitors. I close the lid on the laptops and the display continues to work.
On the GT70, the system shuts down. It won't allow me to use the external keyboard and mouse or display the session.
Any suggestions if there is a configuration option to allow the GT70 to continue to function with external monitor and lid closed.

Yup. This is a windows setting. You need to go into your control panel -> power options -> "Choose when the computer sleeps" and "Choose what closing the lid does"
That should solve the problem. I currently have my GT70 hooked up to a 42" TV and I can close the lid and it stays on and the TV continues displaying as well. No problems. =]

External Monitor and LXDE

I run Arch + LXDE on my laptop and everything works great. Recently, I attempted to attach my laptop to an external monitor and use lxrandr to output only to the external. When I first tried it, the output worked fine but I was unable to adjust the resolution on the external monitor to anything greater than the best resolution I can get with my laptop. After restarting X, though, I was able to get max possible resolution on the external. However, this does not happen automatically, and every time I attach the monitor I have to reset the resolution to the best possible. Also, PCManFM only displays the desktop on a portion of my monitor equivalent to the laptop resolution (1280x800) even though the laptop monitor is disabled by lxrandr. The rest of the desktop is just openbox; when I right click on it, I get the openbox menu. Furthermore, when I attempt to switch to an agetty, the display is not aligned and most of the left side of the output is cut off. However, if I open the laptop, the agetty output works nicely there.
The agetty problem doesn't surprise me because that has nothing to do with Xorg, but it would be really nice if everything just worked. I have tried looking for similar problems (and solutions), but I can find very little information. I would like to have PCManFM put the desktop on the whole display, I would like to have the best resolution automatically when I plug in the external, and (maybe) I would like to be able to use the agetty terminals when I just want to work from the terminal.
Thanks!

I want to avoid setting up a xorg.conf file, and arandr works pretty much the same way as lxrandr. So I decided to write a simple script that I could run at startup to automatically set the resolution of all attached monitors to the maximum possible. Here is the script, and I can run it from /etc/xdg/lxsession/LXDE/autostart:
#!/bin/bash
query=`xrandr -q 2>/dev/null`
screens=`echo "${query}" | grep '^[A-Za-z].*' | sed -e '/^Screen.*/d' -e 's/[ \t].*$//g'`
c=0
for s in $screens; do
screenarr[$c]=$s
c=$(($c+1))
done
displaylines=`echo "${query}" | grep -n '^[A-Za-z].*' | sed -e '/^[0-9]:Screen.*/d' -e 's/:.*//g'`
c=0
for i in $displaylines; do
resline=$(($i+1))
res=`echo "${query}" | grep -n '.*' | sed -e "/^$resline:[ \t].*[0-9]/!d" -e 's/^[0-9].*: *//' -e 's/ .*//'`
if [ "$res" != "" ]; then
xrandr --output ${screenarr[$c]} --mode ${res} 2>/dev/null
fi
c=$(($c+1))
done
I wrote this really quickly so if anyone has an suggestions for improvement that would be great. I am hoping to generalize this so that you can pass it simple parameters to have some control as to how your monitors are configured. Also, if you have a better way to extract the monitor information than from xrandr -q and regex that would be a huge improvement.
When run from autostart before PCManFM, PCManFM fills the full screen with the desktop.

Preventing SLEEP when using External Monitor and Keyboard

Prior to Leopard, whenever I had an external monitor and keyboard attached and closed the MacbookPro lid the system would not go into SLEEP mode. Now it does.
What's to be done to prevent this from happening?

PS.... when this last occurred, the backup drive for Time Machine disconneted when SLEEP was invoke by closing the lid and did not reconnect when the system restarted.
I also received a 'warning' that a device was not disconnected properly.

Turn off monitor.
All ok.
PROBLEM states:
• Monitor connected and ON, next to macbook in bootcamp win7.
• Monitor connected, ON, and 5ft away from computer in bootcamp win7. (no proximity)
• Monitor connected, ON, and connected to 2nd laptop VGA, display set to macbook so it outputs the macbook in bootcamp win7. (connection)
NOT Problem states:
• Monitor connected and OFF.
• Monitor ON and not connected. (proximity)
• Monitor On, and connected to 2nd laptop on VGA in same location. (proximity)
• Monitor connected, ON, and connected to 2nd laptop VGA, display set to VGA so it outputs the 2nd laptop. (proximity+connection)
• LAN connected, any test.
• In Mac OSX, no problem.
So problem state is when the macbook is in NVidia mode, connected and using external monitor in Bootcamp Win7 over the wireless network. Proximity has no effect. Connection, unused has no effect. No wired LAN problem.
I found some posts from 2007 about OSX having this issue, no one got beyond “it must be the monitor is too close and interfering with wireless”
I would have to say driver issue if OSX is ok, and bootcamp is not. Swapping drivers with Bootcamp drivers, win drivers, no joy.
Ideas?

Wow, I couldn't believe it when I saw it. I've been having really bad wifi troubles only in Windows (7 64-bit Ultimate, specifically), and after looking all over the place I happened upon this post. I immediately unplugged the monitor and voila, the signal improved instantly and dramatically. I ran several tests with the monitor unplugged and plugged, and I can confirm that the monitor is definitely the culprit. I'm also using the DVI adapter from Monoprice. Thank you for this post, time to cancel my order for a new router. I would have NEVER thought to try unplugging/plugging my external monitor (also a Dell, incidentally).
Technical details:
1. Mini DisplayPort to DVI adapter from Monoprice: http://www.monoprice.com/products/product.asp?cid=104&cp_id=10428&cs_id=1042802&pid=5106&seq=1&format=2
2. Windows 7 x64 Ultimate (problem doesn't occur in Mac OS).
3. MacBook Pro 13", newest model.
4. Dell S2409W monitor.

Laggy window performance with external monitor and USB hub after 8.1 -- possible cause found

I have the Yoga 11s which I've been using in conjunction with a Plugable UD-3900 for a few weeks now. Everything has worked very well, especially with external display, keyboard, mouse, and ethernet plugged into the hub.
After upgrading to 8.1 the other day, I began getting very noticeable window and mouse lag on the external monitor. Dragging windows would jump around, aero peek renders were slow, and the 'ribbon' screen saver would pixelate and was slow to wake up.
I installed the updated DisplayLink drivers, and also all the updated Lenovo drivers, but the problem remained. This morning I was trying different ideas and found something very interesting:
The configuration I use when attached to the UD-3900 is to have the keyboard flipped under and the display flipped up in the "stand" so I can use it as a second monitor. Of course when you do that, the Yoga turns off the keyboard & touchpad so they don't get accidentally pressed.
Just for kicks, I decided to flip the keyboard back around and try using the touchpad to move windows around on the extended monitor. Surprise: the laggy window dragging and rendering was gone. And then even more surprising, when going back to the wireless mouse while still in 'laptop' configuration, everything continued to work well -- no lag.
I thought maybe it was an incompatibility with the Logitech wireless USB keyboard/mouse itself, so I disconnected it. However, I also have a bluetooth Microsoft mouse, and it does the exact same thing: With laptop keyboard flipped back & disabled, window drags & aero peek renders lag. As soon as I activate the touchpad, lag is gone, and the BT mouse behaves normally.
So, it seems to be some kind of interaction between the automatic disabling of the Yoga's keyboard/touchpad and any external mouse. Has anyone else seen anything similar? Any ideas on how to solve so I can use the Yoga in the stand configuration?

Just to close the loop on this, I've determined that the cause of my issue is the Intel Dynamic Platform and Thermal Framework software/driver. I've disabled in the BIOS for now, and the machine is working very well. Will look for an update from Lenovo to address more definitively.

Has anyone seen the blue flashing screen on MBP running 10.6.8? It looks like you are plugging in an external monitor and unplugging it over and over.

So, I have called Apple twice about this issue. Both times, I was on for almost an hour and could not get an answer. In fact, the technicians said that they had never seen this issue before. Here is how it goes.
It has happened MacBook Pro laptops anywhere from 2010 to now. I have seen it on new ones with Thunderbolt and ones a generation before. In the environment I work in, we have many, thousands from ranging from all generations. This specific issue seems to only be affecting 10.6.8. When the computer boots, it starts to flash blue as if you just plugged in an external montior, except there is no monitor, and it keeps flashing blue about once every second. I actually have a video of it on my phone that I can send to show you.
Now, like I said, this is happening to multiple laptops, all running 10.6.8. There isn't a particular action that causes it either. I have seen laptops that have been running for hours just start doing it as well as a completely cold start up do it right at the login screen. Upgrading to 10.7.x seems to solve the issue. But you have to understand, the environment I work in has thousands of computers. Upgrading many of them to Lion just for this is just not practical. In some cases, there is software that will not function correctly beyond 10.6.8.
I have scoured though Google searches for hours now looking for a similar issue and a resolution. The answer I always seem to find is just upgrade. I can't seem to find a discussion beyond 2011 that talks about it.
Can someone help me?
Chad

By the way, I have tried shutting of the display switching in the power settings. That was basically the only real answer I found anywhere. It didn't work.

External monitor and bootcamp

hi guys, my external monitor works perfect with leopard but with windowsxp don´t and it goes on blue screen error. Seems to be tipical windows drivers problem. Any idea?
Thanks!

Hey mayaman,
Did you install the recently released Bootcamp update?
If not, get it here : http://www.macupdate.com/info.php/id/27367/apple-bootcamp
I don't get a blue screen but Windows Vista in that case won't recognize my external Display. Only after a reboot it works without any issue.

Port Replicator loses connection to 2 external monitors and moves all the windows to the main screen

I recently purchased a Lenovo USB 2.0 Port Replicator with Digital Video (0A33942) to use with my Lenovo ThinkPad E530 laptop and two external monitors. One of the monitors is plugged into the port replicator with a VGA cord and the other one is plugged in directly into the laptop also with VGA.
The issue I'm having is randomly during the day, both screens will go blank, when they come back up everything that was open on the second screen gets moved to the main one. This happens about 15 times a day and although not a life threatening issue, it's still more of an annoyance moving everything back to the second screen as it was originally set up.
I have gone to Power Options and I have switched the sleep mode to 'Never'. Anyone have any suggestions? This is really driving me nuts. I tried calling Lenovo support and they told me this wasn't in "their scope" of support issues.
Thanks

this is a driver incompatibility issue, it happens with some displaylink devices. I had this problem with the Lenobo USB 2.0 port replicator before.
Since the E530 has USB 3.0, i suggest you get a Lenovo's USB 3.0 dock, which will support 2 external LCD (but only one of the dvi on the dock can be converted to vga).

External display and sleep issues

A 15-inch MacBook Pro worked fine with an external display and keyboard prior to the 10.5.2 update. After the update the external display goes dark when the laptop is closed. Hitting the external keyboard momentarily wakes up the external display but then it almost immediately goes back to sleep. It's as if the MBP thinks it's in battery mode and not plugged into an AC outlet.
All Energy Saver settings are to keep the display awake. Could this be a corrupt driver or some other issue?
Thanks.

Theres been a lot of disscussion about this and it's a BIG problem. Check this out:
http://discussions.apple.com/thread.jspa?messageID=6597635&#6597635
http://discussions.apple.com/thread.jspa?messageID=6669894
A lot of us are having the following problems after the graphic update:
-not waking from sleep (waking, but display staying dark, restart is only solution)
-not being able to use in clamshell mode (with external monitor)
-not being able to run external monitor at full resolution
I've also had some weird bugs like the settings and calibration of my external somehow coming over to my MBP monitor after disconnecting the them.
I hope Apple can fix this.
