Connecting Displayport Monitor with Thunderbolt 2

Recently picked up the Samsung UD590 and was using it connected with HDMI on my Mac Pro. No issues with that. Knowing Thunderbolt can handle 60fps and the geometry of mini display port match up, picked up a cheap mini displayport to Displayport cable from CableMatters brand to see if you can actually push thunderbolt signal through the old cables. The connection felt a little loose on the Screen end, and the Signal from Thunderbolt is definitely letting me run 4k at 60fps. (though my software is actually displaying 56fps cap) But there is a line of fuzzy tearing of the images down the right side of the screen about half an inch wide. I figure its one of three things causing the issue. Either A) This was never meant to be and theres something native about Mini display port cable that just won't let this work, B) the cable is bad, or C) the port on the samsung is bad.
I'm going with Option B and going to return the cable for a new one, but if anyone has any input on this, I'd greatly appreciate it.

Yes if you use a mini displayport cable verson 1.2 and your monitor supports DP 1.2 as Grand said.
MacBook Pro (Retina, 15-inch, Late 2013) or Mac Pro (Late 2013) also support multi-stream transport (MST) displays at 60 Hz . These displays need to be manually configured to use MST. Follow the steps below to use the display's built-in controls to enable this feature.
Sharp PN-K321: Choose Menu > Setup > DisplayPort STREAM > MST > SET
ASUS PQ321Q: Choose OSD menu > Setup > DisplayPort Stream
Dell UP2414Q and UP3214Q: Choose Menu > Display Setting > DisplayPort 1.2 > Enable
Panasonic TC-L65WT600: Choose Menu > Display Port Settings > Stream Setting > Auto
Your Mac will automatically detect an MST-enabled display. However, your display may require a firmware update to support 60Hz operation. Please contact your display vendor for details. If your specific DisplayPort display is not listed above, check with the display’s manufacturer for compatibility information.
From:
Using 4K displays and Ultra HD TVs with Mac computers
I have the Dell and had to set it up as described above to get 60 Hz.
Your monitor supports:
Your Samsung UHD monitor is perfect for your game consoles as well as your PC. Thanks to 2 HDMI ports, both your computer and your console can be connected simultaneously, so you don’t have to unplug and plug in each time when you want to switch between them. That means less hassle and more time for entertainment. Thanks to DisplayPort connectivity, your monitor is also ready to connect to UHD-compatible devices and content. *Supports HDMI 1.4 (3840 x 2160, 30Hz) and Display Port 1.2 (3840 x 2160, 60Hz)

Jumpy Mouse when connected to monitor with Thunderbolt-to-miniDVI-Adapter

Hello everybody,
I have a Macbook Pro with Mavericks installed.
I've been working with a plugged in Packard Bell Monitor on my MBP for a few months now, everything went good.
But now, since yesterday, the mouse jumps all over the screen and it's really annoying!
I googled the problem and I now know that it's because of the Adapter I'm using, but it's strange.. I've had this monitor setting for quite a long time with no problems and now from one day to the other, there's this problem..
When I work only on the Macbook without a plugged in Monitor, it works normally and smoothly.
I even bought a new magic mouse because i thought it could be the external trackpad i'm using, but the problem is still here..
I cleaned my deck, cleaned the trackpad, cleaned my hands..
Sometimes the cursor moves only from left to right..
Do you know a way to fix this problem? Buy a new adapter? Buy another adapter? Buy a new monitor?
Thanks for your help!
BTW: Excuse me for my "not that perfect english" :')

Update.
Still having the problem.
I changed the mini displayport to displayport cable:
http://ca.startech.com/Cables/Audio-Video/DisplayPort/6-ft-Mini-DisplayPort-to- DisplayPort-Adapter-Cable-Male-to-Male~MDP2DPMM6
to this cable and am still having the same issue:
http://outlet.lenovo.com/us/en/itemdetails/0B47091/460/8FA0422CA6EA48B0BDED71D28 7F73673
I have heard that the issue may have something to do with the number of pins contained in the cable:Try another DisplayPort cable (One that is VESA compliant). Non-compliant DisplayPort cables may have snyc issues and may also have the # 20 pin pwr cable active. The # 20 pin is not suppose to be active and it may cause damage to your hardware.
The new Lenovo cable does not indicate if it is VESA compliant.
The main issue here is that after the Macbook Pro screen flashes blue upon waking, the screen brightness keys do not function. Only after removing the mini dispalayport cables do the brightness keys (F1&F2) function again.
Would really appreciate it if someone knows how to solve this issue?
Kind regards

3 DVI monitors with Thunderbolt Mac Mini

Is it possible to have 3 DVI monitors with Thunderbolt Mac Mini?

Maybe.
The first could be via a Mini Displayport to DVI adapter
The second could be via a HDMI to DVI cable
The third would have to be via a Displaylink USB adapter
It should be noted that the AMD powered Mac mini 2011 model will handle this workload better.

Can I connect a monitor with built in speakers to my macbook air?

Can I connect a monitor with built-in speakers to my macbook air? What would you suggest in the 22" - 24" size for everyday use?

If you say that there is built in speakers. Most probably the connection is HDMi. You will need an adapter to connect the MacBook Air to the monitor through HDMI, at the same time, the adapter needs to support video and AUDIO.

Mac mini cannot dect View Sonic VX1035wm display with Thunderbolt port-to-DVI-D interface.

Hi warlotte,
Thanks for contributing to the Apple Support Communities.
If you have an Apple Mini DisplayPort to DVI adapter, it can be used with the Thunderbolt port on your Mac to connect an external display.
For more information, see this Frequently Asked Questions document:
Apple Mini DisplayPort adapters: Frequently asked questions (FAQ) - Apple Support
Some Apple computer have a Thunderbolt port instead of a Mini DisplayPort. Computers with a Thunderbolt port will have the following symbol next a port although the port physically appears the same as a Mini DisplayPort:
Thunderbolt ports:
Are compatible with all of the Mini DisplayPort adapters referenced below in question 5 and with Apple Mini DisplayPort equipped displays.
Note that "question 5" mentioned refers to section 5 of the above FAQ, which has a list of Mini DisplayPort adapters that are available from Apple.

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.

Connecting la2306x monitor with mac book pro retina

Hi There
I just bought an HP Monitor la2306x, and tired to connect it with my Mac book pro Retina. I attempted the connection via HDMI Cable and a HDMI to Display Port Adapter, but the monitor didnt find the connection.
I then attached an HDMI to DVI adapter to the Monitor and still nothing, the Laptop did seem to notice that i connected another display as the screen went on and off but nothing was shown on the monitor.
Using the same connection i tried connectiong my PS3 and it connected through HDMI to DVI.
Can the monitor work with Macs? I didnt think it would be a issue
Thanks a lot for your Help!

Hello naja89,
You want to connect a monitor to your MacBook.
You might have to change a setting on the computer.
The cables connect to the Thunderbolt/Mini-Display Port, and you then have to select System Preferences > Display and use Mirroring or not according to how you want to operate.
I found this on the mac forums.
Here is the link to the forum.
Clicking the White Kudos star on the left is a way to say Thanks!
Let me know how everything goes.
Have a good day.

Sun Ray 2 - Connecting to monitor with USB Hub issues

Hi,
We recently purchased 21 Sun Ray 2 devices and 21 Dell 1909W monitors with built in USB ports to go with them.
This combination works great with 17 of the Sun Ray 2 devices, i.e. mouse and keyboard connected to USB ports on monitor then A to B USB cable running from Sun Ray 2 to Dell monitor.
However, on 4 of the setups this combination fails to work, and after troubleshooting we identified neither the Sun Ray 2 or Dell monitors were faulty. Our support agents suggested since Dell could use a different USB hub 'engine' for their monitors (Even the same model of monitor) this may cause problems being picked up by the Sun Ray 2 devices.
After trying out a box of spare A to B USB cables we had lying around spare, surprisingly 3 of the 4 before non working devices are now working. However, if the 'magic' leads were to be stolen etc we would have a problem again!
Are there any sorts of firmware updates etc for the Sun Ray 2 devices that would mean we could get all the monitors working with the standard Dell provided A to B USB cables? At the moment the optical light on the mouse will 'blink' and then nothing else will happen (It does 'blink' on the working setups before getting full power).
Many thanks :)
John

no I tried with bro's iPod which have 4.x firmaware and it works fine. So I guess it's safe to assume this is problem because of firmware

When I try to connect a monitor with a thunderbolt to hdmi from the back of my thunderbolt monitor nothing happens. When I plug in the cable directly to my Mac mini it works great... Any idea this isn't working?

Well pretty much the title sums it up, but I'm required to type something here so here is some words. (Please excuse frantically errors since I'm working from my phone).

You can't connect a non-Thunderbolt display or adapter directly to the port on the back of a Thunderbolt display. It will work if you connect a Thunderbolt disk drive (with two Thunderbolt ports) between the two displays.

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.

IMac won't offer display mirroring option when connecting to HDTV with Thunderbolt to HDMI cable

I have an iMac, and am trying to connect to my HDTV to use as a second display (mirror). I am using a cable with a Thunderbolt connector at one end, and an HDMI on the other. I know the cable works because I have used it with my MacBook on other TVs. When I use this on my MacBook, I simply open displays, and between the tabs marked "Display" and "Color" there is always an "Arrangement" tab to select. When I try this same setup on my iMac, the only two tabs I can see are "Display" and "Color" - the option to mirror disdplay (or recognize the HDTV in any way) simply doesn't exist.
I would welcome any help. Thanks much, Doug.

OK, yes your Mid 2011 has a Thunderbolt port.

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?

Has anyone had success connecting 3 monitors with a Matrox TripleHead2Go?

I have a Matrox TripleHead2Go Digital Edition external monitor box but have had no luck getting it to work with 3 monitors on Mountain Lion.
First I managed to get it to drive two monitors, except there seemed to be no way to split them into separate monitors, as claimed in the advertising.
Then I got a 3rd monitor and connected it to the box and reconfigured the software. That is when the problems started. For a short time, it displayed on all 3 but with very low resolution, 600x800. When I tried changing the resolution then it would only display on one monitor through Output 1. That is a much as I have managed. I tried many times trying different settings, each time waiting 5 minutes each time. I have uninstalled and re-installed several times, tried different combinations for monitors. Nothing helps.
So I am wondering whether just to give up and use it as a paperweight and assume only PCs can use multiple monitors?

Trying to use a THTG digital (DVI) with a 2014 MBP retina.
Although it isn't supposed to work it does, although the matrox configuration tool is very annoying, keeps rebooting the machine, and I ultimately failed to connect 3 devices.
It is happy run 2 pico projectors at 1280x720@60x2, no problem. Insists on them being in ports 1 and 3.
Trying to connect a 3rd normal sized projector via VGA, resolution changes to 1280x720@50 and the picos won't work with it. Keeps asking to reboot OSX and not setting the resolution asked 1280x720@60x3, keeps setting 50hz.
I have moved from using Ubuntu on a dell laptop to OSX, and I really miss the power of xrandr to configure from the command line. This was my bible for several years: http://www.brandon-harris.com/ubuntu/dualhead2go/triplehead2go/2011/02/01/matrox -dualhead2go-triplehead2go-on-ubuntu-with-ati-amd.html
