Hi Heim,
We have little experience on the Mac products therefore we can provide you some feedback based on our internal testing on the Intel HD 4000 chipset which you have on your Mac Mini.
Test results on the HD 4000 on the CSV-5300A it does output all at 1080p on 3 displays but unfortunately it acts as a second display, it will not work on 3 independent 1080p displays.
I think I can blame this to the driver support.
On the HD5000 series we have found that it works well supporting 3 independent displays at 1080p.
On both cases the test was done on the Intel NUC with Intel HD 4000 graphics and HD5000 graphics.

At hardwareluxx in Germany they tested our Y-Cabled Docking station which uses the same chipset as the CSV-5300A, the STDP 4320 and they were able to drive two displays without issues with the Intel Graphics Iris Pro.

You are absolutely right about the Matrox in regards of the MST Hub. The MST can always drive displays from your graphics source, it does not became obsolete as it does not have an independent graphics chipset in a box.

I hope this information help you to make your own decision.

Regards

Hi Link,
The one that comes with the card is just a passive adapter.
The Startech seems to be an active adapter, if you are using this adapter on all 4 Mini DP ports you should have picture.
nGear it is passive.

[Paul]

Hi Link,

Thank you for your reply. Can you detail me the make and model of the active adapter?

Hi Kostas,
Here is the latest chipset drivers for the AMD 760G.
Here are the steps for your error 124
1 Ensure that none of the hardware components are overclocked. Hardware that is driven beyond its design specifications – by overclocking – can malfunction in unpredictable ways.

2 Ensure that the machine is adequately cooled. If there is any doubt, open up the side of the PC case (be mindful of any relevant warranty conditions!) and point a mains fan squarely at the motherboard. That will rule out most (lack of) cooling issues.

3 Update all hardware-related driver: video, sound, RAID (if any), NIC… anything that interacts with a piece of hardware. It is good practice to run the latest drivers anyway.

4 Update the motherboard BIOS according to the manufacturer’s instructions. Their website should provide detailed instructions as to the brand and model-specific procedure.

5 Rarely, bugs in the OS may cause “false positive” 0x124 events where the hardware wasn’t complaining but Windows thought otherwise (because of the bug). At the time of writing, Windows 7 is not known to suffer from any such defects, but it is nevertheless important to always keep Windows itself updated. 

6 Attempt to (stress) test those hardware components which can be put through their paces artificially. The most obvious examples are the RAM and HDD(s). For the RAM, use the in-built memory diagnostics (run MDSCHED) or the 3rd-party memtest86 utility to run many hours worth of testing. For hard drives, check whether CHKDSK /R finds any problems on the drive(s), notably “bad sectors”. Unreliable RAM, in particular, is deadly as far as software is concerned, and anything other than a 100% clear memory test result is cause for concern. Unfortunately, even a 100% clear result from the diagnostics utilities does not guarantee that the RAM is free from defects – only that none were encountered during the test passes.

7 As the last of the non-invasive troubleshooting steps, perform a “vanilla” reinstallation of Windows: just the OS itself without any additional applications, games, utilities, updates, or new drivers – NOTHING AT ALL that is not sourced from the Windows 7 disc. Should that fail to mitigate the 0x124 problem, jump to the next steps. Otherwise, if you run the “vanilla” installation long enough to convince yourself that not a single 0x124 crash has occurred, start installing updates and applications slowly, always pausing between successive additions long enough to get a feel for whether the machine is still free from 0x124 crashes. Should the crashing resume, obviously the very last software addition(s) may be somehow linked to the root cause.

8 Clean and carefully remove any dust from the inside of the machine. Reseat all connectors and memory modules. Use a can of compressed air to clean out the RAM DIMM sockets as much as possible.

9 If all else fails, start removing items of hardware one-by-one in the hope that the culprit is something non-essential which can be removed. Obviously, this type of testing is a lot easier if you’ve got access to equivalent components in order to perform swaps.

Hi Link2110,
The 295X2 has 4 MiniDP and a standard DVI port. If you do not have DP displays you can run 1xDVI and 1x DP without active adapters. From the 3rd monitor till the 5th you need to use active adapters.

Hi Kostas,
Welcome to Insights!
In order for us to help you please detail us your PC hardware, OS, driver version etc.
This will help us to see what could have gone wrong with your installation.
I will advice you to update your mainboard BIOS as the first step to resolve your problem. 
Thank you in advance.

[Paul]

Hi there!
We apologize the inconvenience caused.
Please send a mail to [email protected] with the serial number of the graphics card and please attach the invoice. We will provide you the RMA number and instructions to return the card for service.
Thank you for your support.

[Paul]

Hi Strongdoctor,
Can you tell us what i the GPU temperature read you get when the VRM is at 100-110?
I have consulted with some engineers and the 100-110 is still in the safe range as long as the GPU temperature does not exceed 95C

[Paul]

Hi Digital,
Sorry to hear about the problem you have.
Can you please deinstall the driver and install the previous Catalyst 14.9? I want to know if you have the same result.
Get back to me when you do this. 
Thank you in advance.

[Paul]

Hi Strongdoctor,
The VRM on this card should max out at 95C, not 110C. If your case properly ventilated? If yes I suggest to service the card and place a note that the VRM gets too hot. Please send me a private message with your serial number so we can check the card when it gets back.
We apologise for the inconvenience caused.
Regards

[Paul]

Hi there,
We are sorry to hear about the problem.
Please use the latest driver Ver. 7.7M3 to see if it resolves the problem. The version provided on the driver is the 7.7M0.
You can find the latest driver here

[Paul]

Hi BHi,
The BIOS screen capture is the standard PCI not the PCI-E, do you have a choice for PEG or PCI-E, some mainboard vendors place a different name on it.
Also try different cables or different ports on the VGA card to see if the problem comes from the card reading the monitor information. When there is a mismatch there are cases the monitor sort of panics as it cannot process the information coming from the VGA card.
Regards,

[Paul]

HI Rune,
Did you deinstall the previous graphics card driver?
Make sure that both PCI-E power connectors are attached to the card as well.

[Paul]

Hi,
I normally trace the problem from the source all the way to the end.
1. Can you check if you can press the scan/reset button on the back of the MST Hub to see if it helps?
2. Can you check if you can swap the HDMI cable to verify the cable is not the problem?
3. On the Samsung HE40A, did you check the picture modes for Screen Fit and Smart View1? You can check in the manual here

4. Auto adjustment?

In regards to the custom resolution 1080p 30Hz if I am not mistaken it is supported by the Catalyst driver. Also note that in the CCC there is an option to add custom resolutions if unavailable, add the required resolution with refresh rate and then apply it.
Note that HDTV has image post processing job so it decodes every frame sent to the TV, depending on each image mode, if the processor is not able to handle the job it will blank the image.
Also in the CCC there is a choice of color formats YCbCr 4:4:2, YCbCr 4:4:4 and RGB (HDMI Limited/Full Range). HDTV has support of the Luma/Chroma “YCbCr” on all refresh rates but not in RGB. Try YCbCr 4:4:2.
I hope this helps your inquiry.
Thank you for your support and we hope everything gets resolved.

Hi,
Sorry to hear about the troubles.
If you hooked the second screen with the HDMI monitor and works, the first monitor the issue probably comes with the cable you are using.
Deinstalling the drivers please follow these steps;

If you have issues after installing AMD driver suites, this is one method you can try.

To perform a ‘clean install’ of AMD graphics drivers:

You should make a system restore point before attempting, just in case 

1. IMPORTANT: All Windows Updates should be current, including the ‘optional/suggested’ updates
2. IMPORTANT: Disable all anti-virus/ad blockers/anti-malware/ anti-anything before trying to install
3. IMPORTANT: Netframework is required and must be the latest version. (from Windows Update)

Download the drivers for your computer to the desktop. Follow steps 1-5 ( http://support.amd.com/en-us/download ).
 Do not use ‘auto-detect and install.

Delete existing drivers from your computer:

In computer control panel select ‘uninstall a program’
For computers with Intel processors:
Select AMD install manager and choose ‘express uninstall all AMD software’
Including the install manager.

For computers with AMD processors:
Select AMD install manager and ‘custom uninstall’ the graphics drivers and CCC only.

Reboot into ‘safe mode’
In safe mode run Guru 3D’s DDU

Reboot

Install the new driver suite.

NOTE! Certain laptop configurations are not compatible with AMD’s Mobility Catalyst™ Driver. 
      AMD provides graphics drivers for most laptop brands and models for the Mobility Radeon™ HD series of graphics cards.
      If the AMD Mobility Radeon Driver Verification tool reports that the hardware is incompatible, then the notebook manufacturer is the exclusive provider of the graphics drivers for your notebook. (GPU-28041) 
      Sony, Toshiba, and Panasonic will not accept generic drivers. Get drivers from manufacturers support site.
      Laptops with ‘switchable’ graphics must use manufacturer supplied drivers.

Also note that some users had some issues with this Microsoft update kb3004394
You can uninstall it to verify if this is causing the problem.
