lxde works from remote desktop but not on HDMI

I have BBB rev C. I updated eMMC with debian version 2015-03-1 version 7.8. It has Lxde preinstalled.
Lxde works with remote desktop, but not on HDMI monitor. The HDMI monitor only shows beagle dog image.

Can any one tell me what is wrong with my setup.

First, do you see the mouse cursor moving?

If so, turn off HDMI over-scan on your HDMI monitor as the menu is underneath.


Thanks. it works after screen size adjustment.
