W530 (primary) with external monitor which stutters video, help?

So I connected my w530 to an external monitor. When my w530 is the primary display, video I play on the external monitor stutters (very choppy). However, when I make the external monitor my primary display, then there is NO lag. There is a clear difference. What's wrong?

Hi, Poonti
Have you checked your video settings in BIOS? If not, then I would recommend doing so to make sure that this issue is not being caused by a setting.
To enter the BIOS, turn on the machine and tap Enter repeatedly. Do this until a meny appears with a list of options. Press F1 to enter the BIOS. Once in here, navigate to Config ► Display and see what the setting for the Graphics device is. Try setting it to Switchable if not already set at that.
Hope it helps,
Adam

My MBP recently started logging itself out. I narrowed the problem to the external monitor which is connected with a Thunderbolt adapter. When I disconnected it, the problem went away.

My early 2011 MBP laptop (OS Yosemite 10.2.2) recently started logging itself out. I narrowed the problem to the external monitor which is connected with a Thunderbolt adapter. I installed Thunderbolt firmware update 1.2, that did not correct the problem. When I disconnect the external monitor, the problem went away. Is there something I can do to be able to use the external monitor again?

HP Pavilion DV6; Black Screen & Atikmpag.sys BSOD with external Monitor

Hello Guys.
I have HP Pavilion DV6 Core i7 with ATI Mobility Radeon HD 5650 Graphics Card. Two weeks ago, I started getting continous Atikmpag,sys BSODs. The operating system also started giving me warnings about the hardrive. After a few days, the BSODs got more frequent. Then one day, I was doing normal stuff on my PC and the Display Driver crashed. Instead of recovering, the PC froze. I forced restart my PC but it got worse. The display of my laptop went black. I connected the laptop to external monitor which detected the display. When I tried to load the windows, it started giving me the Atikmpag.sys BSOD on the start up. Now the operating system works fine in the Safe Mode but with nothing on the laptop's screen. The soultions I have tried so far are.
-Reinstalled the windows thrice
-Removed the drivers and installed the updated ones a bunch of times.
-Rolled back the bios to an earlier version
-Removed the hardrive and tried to load it from an operating system installed on external flash drive
-Tried loading the PC with linux on external flash drive
-Opened the laptop and cleaned it thoroughly
-Removed all the components and plugged them one by one.
-Removed the old Atikmpag.sys in system32 folder and expanded it with the latest ones.
-Installed every thing fresh from HP website
None of these tricks have given me any luck yet. The only way, I could use the operating system in normal mode, is to delete the atikmpag.sys file in safe mode and then log on back in normal mode. I also analysed the minidump file through window debugger and it says that atikmpag.sys is causing this crash with the TDR message. I did all these with an external monitor as the display of the laptop is black since that day.
Below are the detailed specs of my laptop.
OS Name: Microsoft Windows 7 (64 bit) Home Premium
Version: 6.1.7601
System Model: HP Pavilion Dv6 Notebook PC
Processor: Intel Core i7 Q 721 @ 1.60 GHz
Bios Version/Date: Hewlett- Packard F.29, 11/7/2011
Installed Physical Memory (RAM): 6GB
Graphics Card: ATI Mobility Radeon HD 5650 1 GB
I have tried almost every solution available on these forums but still have not gotten any where. I am wondering how could the display, graphics card and hard drive stop working at the same time .
I would really appreciate if someone colud help me through this problem.
Thank you

Inkscape/X11 Problems with external Monitor

Hello,
I´m using Inkscape to create vector art on my MacBook Pro.
Since my update to Mavericks I´m having problems with X11. I have the version 2.7.5 of XQuartz installed currently.
After some troubles, Inkscape opens up just fine.
But I cannot drag Inkscape over to my external monitor, which is based to the right of my notebook.
Inkscape simply disappears.
I´m quite the DAU ;-) with Computers and Software, so it would be nice, if you can help me.
Thanks a lot in advance!
Best,
Sonja

Macbook Pro Retina to external monitor - which cable?

Hi, I have a Macbook Pro Retina and I want to connect it to my 22" Viewsonic external monitor - which has a VGA connection going into it. Looking at all the cables I'm confused at which one I should get? Any info would help!
Many Thanks

Thanks for your help What about a HDMI to VGA cable? Would this work?
Where would you find one of those? Never heard of that. That is not to say they don't exist. Why would you want to try that? That would mean you are taking a digital signal, converting it to analog, then converting it back to digital.
Stick with the common methods as I described. Tell us if your monitor has HDMI or DVI inputs and I can be more specific as to what cable to use.

Can I use MacBook pro A1211 with external monitor, screen has died but

CCan I use MacBook pro A1211 with external monitor, screen has died but computer seems fine

Hmm seems like this model has DVI out. You could just plug a standard DVI monitor into that. Or use the DVI connector (VGA supported with included adapter; S-video and composite video supported with optional adapters) adapter that came w/ your machine.

Yosemite: Turning off Macbook Pro screen (lid open) with external monitor connected

Here we go again, this worked pre-Yosemite. Now it seems this trick no longer works. After following these steps again the screen on my Macbook Pro now turns on after logging in and opening the clam shell.
Anyone figure out/know a way to turn off the screen on the Macbook Pro with external monitors plugged in? (yes, closing the clam shell–but I'm referring to keeping the clam shell open with the display turned off)
http://gizmodo.com/5938452/a-trick-to-make-using-an-external-monitor-with-your-m acbook-way-better
To execute in Terminal:
sudo nvram boot-args="iog=0x0"
To undo in Terminal:
sudo nvram -d boot-args
Once you type it into terminal I believe you need to enter your password. I then restart my machine. Now the TRICK is to either restart your machine with the lid already closed (hit restart then slam the lid!) OR turn the machine on for the first time (then quickly slam the lid!) once you are past the login screen you can open the lid.

Has anyone experimented with tip 2 (active corners)? Perhaps it still works.

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. =]

Mountin Lion has trouble with external monitors

Not so much a question as a shout-out. Since going to Mountain Lion, my pretty new (February this year) MacBook has been having no end of trouble with external monitors. I use it a lot with the clamshell closed with two different external monitors of two different sizes, one at home, one at work. It sometimes thinks the one is the other, or if I unplug the monitor in sleep, when I later open the clamshell, the screen stays black and I have to force a reboot with the power button. Never had these problems with exactly the same set-up in Lion. Sometimes it also refuses to find a connected monitor or projector, I have to pull the dangle and put it in again.

If memory serves, one of the 'flaws' with BM's hardware is that it will not convert on-the-fly. So if your sequence doesn't match what the TV is accepting, you get black.
For example, my TV will not accept 1080p, only 1080i, so working in a 1080p sequence would produce no image for me as the BM will only output exactly what's in the sequence, it can't convert my 1080p/24 sequence into 1080i/30 for output.
Now I'd expect your TV would have no trouble accepting a 720p signal but, maybe the above data will lead you down a path of investigation.

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.

MacBook Pro won't stay asleep with external monitor attached. When sleep is selected from the Apple menu the computer will go to sleep only to continually wake up...go back to sleep...wake up...etc. every few seconds.

MacBook Pro won't stay asleep with external monitor attached. When sleep is selected from the Apple menu the computer will go to sleep only to continually wake up...go back to sleep...wake up...etc. every few seconds. This only happens when using the external monitor. Does anyone have any suggestions?

Mine does that too. The worst thing is when it goes to sleep, then wakes up and keeps running while the lid is closed and it is wrapped up in a case. I am afraid when the hot weather comes it is going to burn up. I am hoping Apple fixes it in the software or they may have a melted MBP to replace.
Then when I open the lid it is crashed running at fill tilt, pumping out heat to beat the band. I am forced to hold the button down and reboot.
I wiped my hard disk and reinstalled my OS, but it didn't help. I reversed my OS to 10.5.0 and it solved the DVI problem but still won't sleep. This post will probably be deleted by Apple, they did it a few days ago. I just don't know what to do, and I consider myself a real Apple expert. Just hoping you realize you are not the only one.

Mavericks video chat - echo, pixelation, robot voice with external monitors

Hello,
we have recently deployed MacMinis with Dell UZ2715H monitors, which have a built in webcam, speakers and microphone.
Speakers and microphone are connected via USB while the video functions are HDMI.
So, the problem is when users try video chats, the audio is just horrendous, either there is a lot of echo/feedback or just robotic screaming.
It seems to be better when headphones get plugged into the monitor, but would like it to work without headphones.
Does the USB connection introduce any sort of audio delay into the system? Or is there a magic input output setting combination?
(I've checked that both system sound in/out and Messages in/out are set the same.)
TIA.

Hi,
It's magic.
In System Preferences > Sound > Input tab set the input device AND the volume.
It should not bounce the indicator bar to the far right (feedback and "motorboating" can occur at this point). If is is pinned to the far right it normally cuts the feed in the app your are using.
In Messages > Preferences > Video section is a drop down that should list the chosen device in System Preferences.
You may have to change this if there are two or more input choices.
Using two different sound options can introduce strange quirks.
Sometimes there is a delay from one end leading to the Input device "hearing" your speech coming back from the far end in an apparent echo and the doing the sonar type pinging of that until it effects only dogs. (making your ears bleed on the way of course)
Start with reducing the volume setting in the System Preferences after sorting out choices off device. (Set the System Preferences part first).
Then launch Messages and try a Video chat.
If they report you are quite you need to increase the System Preferences Input settings.
If they are quiet then they need to increase that setting at their end - try to stay away from using the Master Output volume as this tends to be the cause of being heard back over the connection and causing the feedback.
Unlike iTunes and some other apps there is no volume control in Messages (or iChat before it).
You can only choose the Input and output devices if there are Multiples (in fact the camera one becomes a drop down if there are more then one)
Basically it tends to be a delicate and magical balance between your settings, their settings and the quirks of the internet causing the odd delay.
In the Video Menu use the Connection Doctor items and using the Stats option during a Chat.
It should be stable. If it is not, go to the Preferences > Video section and select 500kbps as the speed.
This is fast enough for 4 way chats and can smooth out the variances in very fast connections.
If there are too many variances Messages will try to Buffer.
It drops Frames to do this and at some point this will effect the Audio.
The Buffering has not really changed since 1500kbps was about the max service you could get.
Unfortunately Apple have taken down the AIM test accounts that they used to run.

Streaming video with external monitor

I'm having an odd problem using an external monitor with my Macbook Air: I have the Air hooked up to my LCD TV, works like a charm. I like to watch streaming TV from various free online sites, and for some reason I can only get about 10 minutes' worth before my internet connection is lost. Literallly, my Air appears to be kicked off of my Airport network. If I unplug the external monitor, within a couple of seconds the video starts streaming normally again.
Anybody know what's going on?

Sounds like you could be having the core shutdown problems others have been reporting using an external monitor and video. If you search this forum you'll find several threads but I don't think there is a solution. Some have suggested the program coolbook.

IMac with External Monitor

Hi guys, I have a 20" Aluminum iMac with a 24" external monitor. In OSX I have no problems. I can make the external monitor my primary and I can video mirror the displays. However in Windows Vista I cannot figure out how to make the external monitor my primary. (I get the feeling windows won't let me because it is a mobile video card... the check box for which is the primary display is grayed out) This is not a big deal because I only game in Boot camp. So then I decided I could just mirror the displays. With mirroring my game would show on both monitors. I unckeck "extend my desktop with this monitor" but that just disables the monitor. I can find no option to turn video mirroring on. I searched help and it told me to open the mobile computer control panel? but when i opened it Windows said I can only use it on laptops. I am completely stumped. Anyone have any inside tips? Maybe there is just a command I can give to half life to make it play on the second monitor??? I don't know.
Thanks in Advance,
Jeff

we might be having different issues. I get video on the external, but I am unable to make it the primary monitor. I am also unable to make the two monitors mirror the same content. If you are getting no video at all on your monitor something else is wrong.
