solved it my genius self. It was the mini-display port to hdmi cable that was wrong. That cable only went up to 1920 x 1080p. I needed a cable that should go up to 4k which I did went to buy. I plugged I. The new cable and voila! The swcond monitor is now 2k (2560 x 1440) resolution. Happy camper again!
Thanks to to all those who supported me in this most turbulent time. Who were these people? No one! I did it myself! Haha...
I apologize for the delayed response, Intel® recommends the use of high quality cables and straight connections in order to ensure the best performance of the NUC5i5RHY video settings.
