Hi Lee,

I seriously doubt the problem would come from the Firmware …

With your TV i think you can best use HDMI Input 2 (the one with ARC).

As for the cable, if this is the one you have http://www.amazon.com/Monster-Cable-Ultra-1000EX-Speed/dp/B00M295D36

Then it will not be able to give you 4k @ 60Hz I optimal colors, because the cable “only” supports up to 10Gbps and you should have one that supports up to 18Gbps.

Something like this one: https://www.amazon.co.uk/CLUB3D-HDMI-Speed-Cable-3Meter/dp/B0194UCMCU/ref=sr_1_1?ie=UTF8&qid=1463052785&sr=8-1&keywords=cac-1310

Here’s my standard checklist

* Make sure the HDMI cable you are using can do HDMI2.0 or 18Gbps.

I know it sounds a bit “easy” but many cables do state to support 4K but actually do not support that in 60Hz and/or the full bandwidth, that certainly goes for cables longer than 3 meters. It is always best to go for a certified cable, something like this http://www.club-3d.com/index.php/products/reader.en/product/hdmi-20-high-speed-4k60hz-uhd-cable-.html

* On many TV’s you need to turn on “UHD Color” or “Advanced or Enhanced” setting manually in the settings of your TV for the HDMI port to which your pc is connected.

* Also it could help when connecting 2 screens, to set the screen connected thru the Adapter as second/secondary screen

* I advise you to make a custom resolution, set resolution to 3840×2160 at 60Hz and set Timing standard to CVT-RB (reduced blanking)

* Color Depth need to be set to 8 bpc (when running 4:4:4).

What are the 4K formats supported by the adapter ?

Best regards,

Marcel

Good day Alexander,

 

GTX680 can be a bit of a challenge indeed.

Strange colors are most often caused by a HDMI cable that does not support 18Gbps.

What HDMI Cable are you using (brand / type).

nope not really no … but because all the hardware seems to be working, it must be Software/Setting i would say.

[MST1407]

please check if you have the correct HDMI port on the TV (not all ports will probably be suited)
Please check UHD Color setting for the HDMI port in use

Hi All, 
R9 390 in general does not have a problem with support for CAC-1070. Perhaps your particular card. Since it is working correctly for the rest, please check with Gigabyte for a Bios update.
Also be sure to remove all Intel Graphics software (if that is on your system).
Please also check for Bios Update for your mainboard, and check in Bios for CSM (Compatibility Support Module). If your Mainboard has such a setting, please Disable that.
Also Disable GPU Scaling in the Graphcis driver in case that is enabled.

no offence intended, just joke (hence the winky)

answered thru support email …

ok

[MST1407]

what screen do you have ?
which cable do you use ?
which graphics driver version do you use ?

Hi All,
I don’t have feedback from Microsoft.
We started with an issue with a DisplayPort MST Hub not workign when connected to the SP2 / 3 docking, Worked fien when connected directly. For the SP4 they do not make a docking anymore in which you can place the SP i believe … just an normal external universal Docking… 
Although the CAC-1170 / CAC-1070 are quite sensitive with regards to anything in between the source and the adapter … also adn MST Hub which is a lot less ensitive to that also still does not work thru the SP4 dock … you would think it would not be such a big deal to just forward a signal, but apparently more difficult than i realize …

Firmware request please email to [email protected]

good to hear, thanks for the feedback 🙂

Hi Boris,

I am assuming you are using cables no longer than 3 meters (not 36 meters).
That is indeed very weird. 
I have not often heard an MST Hub working and giving such errors … perhaps the Power Adapter of the HUB is not (completely) well functioning … perhaps you can test that with the startech adapter to see if that makes a difference … that should use the same amount of power.
5V 2.4Amp.

how do you think Apple got so rich 😉

[MST1407]

ah ok

[MST1407]

Hi there, thanks.
I will try to get some feedback from factory technicians because i am out of suggestions
Sorry about that :-S
