Elements not playing video full screen with HP 25" monitor. Help??!

I just bought a HP 25es to work with Adobe Elements 14. but I can not get the video to playback full screen. I get a large white bar on bottom of monitor and black bar on right side.

Have no problem playing back video full screen in QT.

Using monitor with HDMI cable connected to a macbook pro in the lightning connection. Tried changing scaling options but nothing helps.Any suggestions?
