Unfortunately the 710+ doesn't have a screen. It's kinda handy though (I now own a MX5500 with limited functionality, but for time display, number of emails etc it's useful)
The only time i really use the screen is when i speak on TS or vent. I don't have dual sreen and it's fun to know who join and quit the channel using the keyboard screen. It's good to monitor temp while running full screen games too.
