    So, I am well aware of the limitations of the 2012 15" macbook pro retina...

    but is it possible that my 2012 could drive a 4k monitor that is running a scaled/(retina) resolution such as 1920 x 1080? Or just by the fact it is still a 4k means I'm out of luck?

    I just plugged my 2012 13" rMBP into my Dell P2715Q using a mDP to DP cable and I get 4K at 30Hz.
    You may not get 60Hz, but if my 13" can do 30Hz your 15" should also.

    Also, 4K monitors can run at multiple resolutions from 1920 x 1080 (1080p HD) to 4K. You 4K monitor will definitely handle 1080p from your rMBP via an HDMI cable.

    best solution

    other than upgrading, what is the best solution for a 2012 rMBP to run a 4K monitor that would normally do 60hz.?

    I've read about DP to HDMI active convertors, using switchresx, using an HDMI cable and somehow getting more than x1080p resolution?

    I'd prefer to get close to a 2560x screen SIZE but with as close to HiDPi as I can get?
