2 External Monitors with the T430s with Intel HD4000

I have read several multiple monitor threads but could not get a clear solution to this.
Model: I have a T430s with Intel HD4000 graphics.
Desired set up: 2 External Monitors + Lenovo LCD
Problem: It seems that I can only drive one external monitor. I'd like to drive two external monitors, as I did previously with my T420.
What I've tried: I have a dock and have tried VGA + DVI for the external monitors, as well as DVI + DVI. Neither setup has worked. It always greys out the third monitor in the Windows Display options.
Any thoughts on how to drive two external monitors with the T430s? Clarity is appreciated. Thank you!

If I'm reading the link you provided correctly, can I correctly assume that I CAN connect two external displays with just the W520 Laptop and NO docking station?
I tested this today. You can connect two external displays (1 VGA, 1 DisplayPort) without a docking station. The result is 3 independent displays - the ThinkPad LCD, the VGA monitor, and the DisplayPort monitor.

HT3131 Is there a way to use 2 external monitors with the MacBook Pro in closed clamshell mode?

My internal display on my MBP is having issues and occasionally displays white lines all over the screen. The current external monitor displays properly. Is there a way to use two extrernal monitors intead of one external + the internal display?

Using an external display with the macbook closed

I am using my big flat screen as an external display with my 2009 13" macbook. I want to be able to close the macbook. But when I do, the external display goes off. is there a way to configure my macbook so that the external monitor doesn't turn off.

My sound is not working with the computer speakers and with headphones, help?!

my sound is not working with my headphones or the the computer speakers

You indicate you have a "brand new Air", you have a 14 day exchange, and the warranty of which you paid for regarding genius bar in-shop diagnostics (and repair if necessary)
What year model Air do you have?
On the first question,....are the headphones attached when you have your Air in sleep?
If yes, then refrain from having phones attached when you close the monitor to prevent this until it is resolved
resolution as to same yet, no.

Can macbookpro be used with the lid closed while using multiple external monitors

I want to use macbook pro with external monitors and be able to close the lid on the laptop, but can't figure out how to make that works with multiple monitors. I currently use two external monitors with the laptop monitor as my third. All are independent monitors and I accomplish this using the matrox diamond bvu-195 product (one for each external monitor). Now I would like to add a third external monitor and be able to close the laptop lid - kind of like you would do with a docking station for a Windows laptop. Anyone have any suggestions as to how to accomplish this?

Connecting your present two external displays via USB has left your MBP's Mini-DisplayPort available for a third. Depending on the monitor's available inputs, buy a mini-Displayport-to-VGA, MDP-to-DVI, or MDP-to-HDMI adapter and the appropriate cable to make the connection. I would expect that adding a third monitor to your GPU's workload might cause your already slow USB-connected monitors to slow down farther, but you'll have to see whether that's true and, if so, how tolerable it is in your work.
As for what will happen when you close the built-in display, I suspect that what happens if you do that now will continue to happen if you do it with a third monitor connected. If you can now close the display and run the machine in closed-clamshell mode, I expect you'll still be able to do so after adding the third external screen.

Audio & video via HDMI to an external monitor with lid closed.

I would like to run a Macbook Pro Retina (2014) with the lid closed and all video and audio via HDMI routed to an external monitor (Samsung Syncmaster from 2010). Is this possible? When I try this, no sound is transferred to the external monitor and I cannot operate the Macbook Pro with the lid closed. As soon as I close the lid, it cuts the signal to the external screen.
I’ve tried looking for previous posts but they’re about MCP’s connecting via Thunderbolt or DVI. Any ideas?

Seems like there may be two separate questions here. Audio working in either configuration and video from HDMI when lid closed. First, you are doing this with the Mac running off of AC, not battery, right?
Audio:
Is the HCMI cable you are using able to carry the audio? Some cables don't.
The only way I've ever used external displays with lid closed is with the thunder port (or DVI) adapter, not with the HDMI. I see the specs from Apple:
HDMI video output
Support for 1080p resolution at up to 60Hz
Support for 3840-by-2160 resolution at 30Hz
Support for 4096-by-2160 resolution at 24Hz
So have you tried varying the screen res to determine the results? I can find no specs regarding what ports remain operational in clamshell. Like you, I would have assumed all of them.
I suspect only the thunderbolt port would support your desired config -- try a thunderbolt/hdmi adapter.
Finally, clamshell mode doesn't allow the MBP to cool efficiently. Heat kills electronics, so if it's too warm or the fans really kick in, you might want to reconsider this setup.

USING A 16:9 external monitor with an X31

I have just purchased an Acer X243HQ 23.6" monitor but have found that I can't adjust the profile of the X31 to cope with the 16:9 profile of the screen. Hence all I get on the external monitor is the computer display profile stretched out.
Any ideas on how to fix the problem?

So are you trying to get the X31 to display on your external LCD only? Have you tried download the newest version of Presentation Director and using that?
Another thought might be the Mobility Modder program. This takes the standard ATI Catalyst drivers and mods them to install on an OEM system like a ThinkPad. Definitely try at your own risk - could have unforseen problems. Make sure you know how to get into safe mode and uninstall the new drivers in case they cause any problems. I also recommend having DriverCleaner handy to clean out the old driver before installing the new one.

I plugged my macbook pro into an external monitor, then unplugged it later and now it is stuck with black borders on top and bottom and zoomed out like it is still on the monitor. How do I fix it?

I started using my external monitor with my macbook pro and as soon as I plug it in it to the monitor it adjusts the screen by zooming out a bit and creating about 3/4 of an inch black borders on the top and bottom of the screen. But these dont show up on the monitor so I assumed it was fine. But when I took it off the monitor, the borders were still there like it was still on the monitor. Any hellp? Its starting to mess with my eyes haha.

Hi aefulcher,
It sounds like you had the external display set to mirror the internal display so the resolution(s) were changed to match each other.

Only black screen on the external monitor with intel-virtual-output

Hello,
I tried to install bumblebee on my Lenovo W520 with this tutorial:
http://www.unixreich.com/blog/2013/linu … ly-solved/
I can activate my external monitor with "intel-virtual-output" and the monitor is switching on. But I can only see a black screen.
In the settings of gnome I can see my external monitor and configure it - but it shows nothing.
Have you any ideas?
Thanks a lot!

How to run an external monitor with lid closed

how to use an external monitor with the "lid" closed

You can use your MacBook in Clamshell Mode with a wired or Bluetooth keyboard and mouse. http://support.apple.com/kb/HT3131

Using MBP with with the lid closed

I have done some searching for tips on using the MBP with the lid closed and there is some conflicting information. I'm hoping people who use their Apple laptops in this way can help clarify a few things.
First, as I understand it, the MBP will operate with the lid closed if there is a connected power cord, mouse, keyboard, and external display. I plan to use mine with a Bluetooth mouse/keyboard. (More details from Apple can be found here.)
These are my questions:
1) I've heard people issue warnings about laptops overheating when running closed, but it seems Apple endorses using the MBP this way. Is heat really a problem, or are people just spreading misconceptions by predicting an early demise for a laptop used in this way?
2) Can the MBP be turned on/off when closed, or only put to sleep? I want to keep my MBP on a shelf that makes it inconvenient to open every time I want to shut down or power up. I suspect putting it to sleep will be good enough, but if I can shut down and power up without opening the lid, that would be preferable.
3) I've read that the MBP can be glitchy when waking from sleep in the closed-lid configuration. According to some people it sometimes won't wake up and requires at restart. Am I fooling myself into thinking sleep can replace shutting down?
Thanks.

1) As long as you don't place anything between the keyboard and screen, you should be fine. There have been worries about display damage due to heat rising up from the keyboard, but no substantiated reports of real damage occuring.
2) You can obviously turn the MBP off while closed by choosing Apple > Shut Down; powering back on requires pressing the power button. Another option would be enabling the Wake on LAN feature in Energy Saver preferences.
3) AFAIK, the problems are with deep sleep and occur regardless of whether the lid is closed or not. I've not had any problems waking my MBP from sleep, but I always shut it down for the night.

Can I stay connected even with the laptop closed?

Is it possible to close the top of the laptop, but still stay connected to the internet? If so, how?
Thank you!

This should explain it.

No, nothing will prevent the computer from going to sleep when you close its display except third-party hacks that are designed to do exactly that. I strongly advise against using any of those, as they may interfere with successful entry into clamshell mode (and they carry other downside risks as well). Just wait until the computer is asleep (with its sleep light pulsing), then press any key on the keyboard. It sounds as though your setup is working as it's designed to do.

External Monitor with XP using closed lid on laptop

Is there a way to turn the laptop screen off and use an external monitor when running Boot Camp and XP pro.
I have bluetooth keyboard & usb mouse. Display is cloned but when you close the lid the screen stays on.Some forums indicates its OK for the screen to stay on when closed, but it does get warm.

Closing the top is absolutly fine but if it strts to over heat you'll have to leave it open for a while
