Controlling multiple displays with debian

[venkat <venkat.s@vortexindia.co.in>]

HI

I have installed DEBIAN 7.8 in N2600 board. 
"http://www.jetway.com.tw/ru/ipcboard_view.asp?productid=939&proname=NF9C-2600/2800"; 
.
On the installed system, we were trying to connect multiple displays 
(Monitor 1 - HDMI port) (Monitor 2 - CRT port). But, we do not see 
anyway to control the connected displays.
Say like :
    Monitor 1 : To display a screen save application
    Monitor 2 : To display some video file.

    I tried xrandr -q :: It shows only screen-0 it does not show HDMI 
or LVDS.

Need some procedures to debug.
Request some guidance.

Regards
Venkat.S
