XRandR and the desktop background image

[Barry Yu]

By using XRandR I inserted a line "Virtual 3360  1050" into the SubSection "Display" to enable dual monitor for two 22" monitors, however the desktop background photo being stretched out horizontally 2 fold and the image is distorted - The icons on desktop and other application windows are remaining fine without any image distortion when drag them from left monitor to the right one or any place in 2 screens, how come the applications and icons can keep normal aspect ration but not the desktop background image? Am I using the XRandR correctly or is there any work around? I inserted a line into the xorg.conf as mentioned above and then issued command "xrandr --output VGA --auto --output TMDS-1 --auto --right-of VGA".
Need help
