    Now , I've had macs all my life but I'm not a true techie . He's my problem

    i have a mac pro 2014 model and i want to run two widescreen monies (LG) and a 4K panasonic Tv connected to the Mac running premiere pro.

    all sorts of problems so finally got the two screens running and a picture out of the HDMI at a dismal 30Htz refresh rate to the Panasonic so its jumpy and rubbish really/

    I bought an HDMI 1.4 to 2.00 converter an put it in the back of the mac via thunderbolt .. i thought this would give me 60Htz

    to top all this the Denon surround sound system that receives the HDMI just keeps dropping the picture every 8 seconds or so and as yet I've had no audio out of it .
    Im not expecting an easy answer but surely there is someone out there with an edit suite in the same configuration i want me ... Help and be gentle.

    do the displays support 60htz at 4K?
    have you tried directly plunging in your computer to the displays 1 at a time?
    dose your Denon unit support 4K at 60htz?
    what models are you displays ?

    the displays are fine its the output to the 4k thats the problem . i didnt have a problem with my old sony surround system
    at all in HD. there must be a way of getting 60htz into the panasonic , as i said i bought an adapter as well to bump up to HDMI 2

    I don't think that you can convert (upgrade) HDMI 1.4 (UHD 30Hz) single to a HDMI 2.0 (UHD 60Hz) signal by a simple convertor.

    The easiest way to achieve that on nMP (by the way, it's the 2013 model, not 2014) should be via a ACTIVE mini display port to HDMI 2.0 convertor.
