Raspberry 7" touchscreen display issue

[soullessninja89]

Hi guys, the list below;
The issue I am having is the 7" touchscreen I have, xbmc is not showing up through the touchscreen, i have not been able to find a setup for this screen. XBMC shows up fine through any hdmi tv. If i connect the touchscreen after 5min the config screen comes up and I have gone through and tried to see if any video output settings will allow the touchscreen to show xbmc but nothing has come up yet, I am still a beginner with xbian and only just started 6months ago with the pi2+ so I am a bit noobish , thanks in advanced for any suggestions
