from 2016 to autumn2018: Using A Video Splitter To Extend Monitors / Cheap Alternatives To Matrox Triple Head?



  • My workplace gave green light to buy a video splitter for a video projection project. So far we are tending towards the Matrix Triple Head DP. Does anyone have an alternative solution? Anything new since 2016?

    The show will be run from a 15 MacBook Pro/late 2017/Memory 16 GB 2133 MHz LPDDR3/ Intel HD Graphics 630 1536 MB...
    Any advice would be very appreciated ....

    I have a question to the Datapaths Fx4, on the data sheet I only read about 60Hz are they capable of outputting 50Hz?

    I don't know... I have only used the now discontinued, older DVI version, the Datapath X4. I really don't recall any problems with refresh ratges...



  • @Michel 

    I'm using the SDI version of the fx4 with 1080p50 signal. I'm using the display port input with 3840x2160 p50

    Works very good.

    Hi,

    I have been interested in the Datapath FX4 for some time. However, I can not see that it provides a compelling case over the Matrox TH2Go. In particular the price of the Datapath fX4 unit is $1900 USD compared to the Matrox TH2Go $300 USD. I can operate 2 x TH2Go on a MacBook Pro simultaneously and achieve 6 x video heads for less than 1/3 of the cost of the Datapath. With the two TH2Go I can operate in configurations of 2,3,4,5 and 6 heads. This appears to me something of great flexibility and economy over the Datapath solution. Please correct me if I am wrong.

    I agree, yet I have had trouble with using a TH2GO when sending HD over SDI. 
    First, the TH2GO (displayport edition) supports max 3x 1920x1080 at 50hz, this is a problem in (or can be) in North America.
    Second, the output isn't always SDI friendly, I have found that the default 1280x720 60hz output settings are not accepted by Black Magic mini converters (a timing issue I think).
    Just a couple things to be aware of.

    Thanks for the reality check! You are right of course, cabling and resolution is going to be a big part of the equation. I am having trouble justifying the price tag of the Datapath units at the moment but that might change.

  • The data path units offer a gerat deal of flexibility and features over the matrox hear, you can specify very specific resolutions and refresh rates, right down to pixel timings, you can also clone and crop displays within the setup and it is all hardware based and 100% reliable. They also give rotation and complete custom resolutions. Matrox gear is OK, but very limited compared to the datapath gear and as @DusX says, they are not great with timings and the drivers are dodgy, they are engineered withe different mentality, the datapath has enough processing power to do anything that it possible with as many pixels as they can push, the matrox gear is spec'd above its capabilities and in reality is much more limited. The datapath feels and acts like a pro piece of gear and the matrox stuff can work in a lot of situations, but it is easy to find situations where the matrox falls flat.

    I hear you. Considering the price difference between the two options it is probably not wise to make a comparison anyway. The cost for the Datapath FX4 in Australia is $2600 + freight, I will have to wait for a big commission or grant before I will be seeing one anytime soon.

  • @bonemap I would suggest, if the opportunity arises, to rent one for a show and try it. One word of warning, to do the config on OSX it is terminal only, but the windows tool has a gui.



  • Thank you so much for all your input! All your comments make it easier to make the decision.... Best regards to everybody!
