I am looking into buying a Dell P2715Q which is 3840 x 2160 to use with a Macbook Pro Retina Early 2013 which does not support 4K but I read that using this adapter and a software called Switchresx it can be done https://www.amazon.com/gp/product/B01B702YTG/ref=ox_sc_act_title_1?ie=UTF8&psc=1&smid=A590JFSRVCU25. My only concern is the HDMI port on the monitor is 1.4 but correct me if I'm wrong, the adapter should convert to 2.0 and the Thunderbolt plugged into the Macbook allow 4K at 60 Hz? Anybody actually using it and can confirm it works ok?
