How to connect VGA Monitor via Thunderbolt Display

I've been using my Macbook Air mid 2013 with a Samsung monitor connected via the Mini Display Port to VGA adapter. I've now bought a 27" Thunderbolt display, which I've connect to my Mac, and assumed I could now daisy chain my samsung monitor into the Thunderbolt port in the back of the monitor. This isn't working.
Is this expected behaviour? Some people have said online that it will work if there's some other Thunderbolt peripheral between the Thunbolt Display and the VGA adapter, but I don't know what kind of peripheral they mean.
Apple support says that my model Macbook air can power two external displays.
How can I get this to work?
Thank you

I want to know if I can connect a vga monitor to the quad by simply getting a vga to dvi adaptor.
Yes, you can.

How to connect the macbook with thunderbolt display 27" to TV with RGB port?

Hi,
I have the following equipments in hands:
1. Macbook PRO 15 inch with 1 thunderbolt port, OS is Mavericks 10.9.2
2. Apple Thunderbolt display 27" identical to this : http://www.apple.com/displays/
3. A Samsung TV with RGB port, & HDMI port.
I want all these displays ( macbook, Apple thunderbolt display & the Samsung Tv) connected at the same time, I had a trial to connect them using a minidispaly adapter to RGB port & HDMI port in the TV but it didnt worked.
Please help!
Thank you.

The Thunderbolt dock adds extra ports:
HDMI (up to 2560x1600 with the Elgato, 1920 x 1200 with the CalDigit)
3 USB 3
Ethernet
Audio in
Audio out
You could also use a Belkin Thunderbolt dock.
<http://www.belkin.com/us/p/P-F4U055/>
It includes a FireWire port, but no HDMI port, so would need a Mini DisplayPort to HDMI adapter (1920 x 1200 max) for the TV. This would use the second Thunderbolt port, so the Belkin dock has to be used with the port on the back of the Thunderbolt display, not between the computer and display.
If you don't need the extra ports, use a Thunderbolt hard drive (with two Thunderbolt ports)
<http://www.seagate.com/external-hard-drives/desktop-hard-drives/backup-plus-desk -mac-thunderbolt/>
This can be your Time Machine drive. Connect the Thunderbolt display to the computer, one port of the drive to the port on the back of the display, and a Mini DisplayPort to HDMI adapter to the second Thunderbolt port on the drive.
You will have three displays with differing resolutions, so mirroring is not going to fill each screen at full resolution.

What is the best adapter for connecting multiple monitors via Thunderbolt?

Currently using two 24" Dell monitors (one T-bolt, one via usb adapter), but have consistently poor performance with USB video adapters. I'm looking to replace one monitor with a 32" LED display via hdmi and would like to move to dual 32's in the future. Recommendations?

I have a mid-2012 MacBook Pro with Retina Display and I use two 24" external monitors.
One is connected via HDMI and the other is connected via Mini DisplayPort to HDMI adapter and I have no problems whatsoever.

How to connect my ps3 via thunderbolt to my imac 27'late 2012?

I have a new imac an old ps3 and will buy the new ps4 once available.
Is anyone aware comcerning a solution to connect these devices?
I need a solution video in (thunderbolt) to video out (hdmi) would prefer of course if sound would go the same way.
Thanks

You would need a display port to HDMI adapter. One of the newer features (which the 2012 iMac has) is that it can display this type of content like a DVD player to the iMac.

Use the above link to review that item. It also has a DVI adapter that you would not use. But the display port to HDMI is the correct item. Then you connect the PS3 to the hdmi on it. I don't think it would passthrough audio though so you would have to figure something out for sound.

Connecting 2013 Macbook Retina 15" to Acer B286 HK monitor via Thunderbolt.

I have a 2013 Macbook Retina 15" and would like to connect an Acer B286 HK monitor via Thunderbolt/MiniDisplayPort.
I am using the standard Apple Thunderbolt cable, but it does not work. The monitor complains about "No signal".

Short answer: I have this exact configuration, and yes, the newest rMBP 15" w/Nvidia card will drive the UP3214Q over HDMI at 4k and 30Hz. It will drive it as a separate desktop with the laptop open, and it will drive it as the sole display -- either way works fine.
Longer answer: You should be aware of 2 things (that I wish I had been more aware of before purchasing the monitor)
1) If you are used to 60Hz or higher, the 30Hz limitation over HDMI is noticable, even in day-to-day productivity work. The mouse lag is very noticable and annoying to me.
2) Scaling/HiDPI support [the way the integrated retina display works] is virtually nonexistant at the resolution you'd want to run it at. What this means is that you either run the monitor at a lower resolution (and everything is blurry), or you run it at full resolution and everything (menu, dock, fonts, etc) is extremely small. You can use SwitchResX to enable scaling support at odd resolutions (for instance, I've successfully gotten HiDPI/scaling to run at 1920x1200 and 2048x1080, with black bars at the edges), but it's not an ideal resolution for this size monitor. I want to match the TB display resolution (2560x1440) in HiDPI mode, but I've been unable to get it working after hacking away at it for 2 days.
I'm hoping that Apple will fix these limitations. Multiple people have reported that MST over DP1.2 works on the same hardware if you boot into Windows, so the hardware support is there -- it just needs to be enabled in the drivers by Apple. Whether they actually will or not is anyone's guess. In the meantime I (and many others) are in limbo wondering if we should return these 4k displays, or keep them and hope "proper" support comes. Since it's not a specifically advertised capability, Apple isn't under any obligation, but I think there's more than a few people hoping that Apple does right by the users and enables the full functionality that the hardware supports.

Welogic 9.2 jdbc connection pool monitoring section not displaying server

Welogic 9.2 managed jdbc connection pool monitoring section not displaying server name. Can you please let me know how can i achive this

Hi,
It happens if the Connectivity is Lost b/w DataBase & WLS Server...In that case in the WLS AdminConsole---DataSource---Monitoring Tab you wont see even the Testing Page with valid datasource to test it.
So please make sure that the N/W connectivity proper....One more thing you can try:
<h3><font color=red>Test-1</font></h3>
You can use *“weblogic.Admin”* utility to Enable and Disable the Pool (DataSource) Just to Confirm whether the dataSource is actually active or not::
Step1). run *"setWLSEnv.sh"* first in the same Shell prompt....then do the following:
Step2). To suspend:
java weblogic.Admin -url t3://localhost:7001 -username weblogic -password weblogic SUSPEND_POOL YourDataSourceName
Step3). To re-enable:
java weblogic.Admin -url t3://localhost:7001 -username weblogic -password weblogic RESUME_POOL YourDataSourceName
To test whether you are getting any Exception or Error while doing this....If yes u are getting any Error or exception then It means there May be some Database connectivity issue...
<h3><font color=red>Test-2</font></h3>
Please use the following Utility to Test the Database connectivity from your WLS Server box:
<font color=maroon>
java -classpath /opt/app/bea/weblogic92mp2/weblogic92/server/lib/weblogic.jar -Dbea.home=/opt/app/bea/weblogic92mp2 utils.dbping ORACLE_THIN DbUserName DBPassword somethingDbUrl.Something.net:1521:dbInstance
</font>
Syntax:
java -classpath /opt/app/bea/weblogic92mp2/weblogic92/server/lib/weblogic.jar -Dbea.home=/opt/app/bea/weblogic92mp2 utils.dbping ORACLE_THIN <DBUserName> <DBPassword> <DBURL>
The above utilty will test the DB Connectivity ...you need to run it from your WLS server Box...
<h3><font color=red>Another Simple Alternative of Test-2</font></h3>

Can I connect MacMini 2009 to Thunderbolt Display with Adapter Cable

Can I connect MacMini 2009 to Thunderbolt Display with Adapter Cable (Mini Display to Thunderbolt Adapter)

Sorry but no you can't.
Only Macs with ThunderBolt ports can be used with the ThunderBolt Display and the 2009 Mac Mini doesn't have a ThunderBolt port.
Which computers can I use with my Thunderbolt display?

Hi - How do I connect an HDTV as a second monitor to Thunderbolt display with macbook pro in clamshell mode?

I have a Late 2011 Macbook Pro in clamshell mode connected to a Thunderbolt Display with the built in Thunderbolt cable. I want to then connect an HDTV via the Thunderbolt port at the back of the Thunderbolt display. I already had a cable that I thought would work which turns out to be a MiniDisplay port to HDMI cable and therefore not compatible with Thunderbolt to Thunderbolt (Mini DisplayPort not being the same technology although it uses the same port - although I'm not an expert !!) So far a web search has provided me with the only solution being using a Thunderbolt dock or storage that has multiple Thunderbolt ports and then using that to daisychain inbetween the Thunderbolt Diplay and the HDTV. The cheapest solution I can find for this would be about £250. Surely not ??!!!!
Many thanks for any comments - Nik

You could also use aThunderbolt dock with HDMI, such as:

Display issue when connecting VGA monitor

I'm having an isue when my Macbook Pro 13 inch 2011 is connected to my LG monitor via VGA, after a while the monitor does not display the image properly I don't know how best to describe it but it is like when a satellite signal is blocky and scrabled. Sorry for the poor description. This occurs both when the Macbook is connected to a monitor with the lid shut so that the monitor is the main display and with the monitor mirroring. I've had a 2008 Macbook with the same set up and there are no issues, anybody know how to solve this?

See if what the user did in this thread:

How to connect my old 20in Cinema Display to my thunderbolt new MacBook Pro?

Hi everyone, I just brought a new MacBook Pro to replace a older model(brought earlier 2010), and a new thunderbolt Cinema Display. I have a old 20 inch LCD Cinema Display all the way from 2005 and brought a mini display port for my old MacBook Pro, worked just fine. However with the new Thunderbolt Display, I noticed there's another thunderbolt port behind and was thinking to connect my old Cinema Display as a secondary monitor. I've brought a thunderbolt port from amazon (http://www.amazon.com/dp/B007KB0EGC/ref=pe_175190_21431760_M3T1_ST1_dp_1 ), but my old monitor still shows black. What did I do wrong here? Thanks!

So currently there are two displays and you expect there to be three?
Can you swap the displays just to make sure there is nothing else wrong?
That is confirm:
1) MBP -> Display A works
2) MBP -> Display B works
Then try:
MBP +-> Display A
|
+-> Display B

How do I connect two monitors to thunderbolt port on MBP 13

The apple rep told me it can be done without Matrox using the dual DVI link, but other people on the web say no. I'm trying to figure out for sure. I want to connect my two non-apple 24" displays.

I thought that was the only was with an apple thunderbolt display, however the Apple rep who was in a Best Buy store told me he had seen the 13" connected to two non-apple displays. If it can be done, I think it's going to be a little weird. Maybe I'll just put one display on the thunderbolt with a dvi connector and the other one on the usb port. As long as I'm not gaming, it should be okay to have a slight lag. Thoughts?
