I actually tried to run system-config-display --reconfig for Sony KDL-40V5500 LCD TV, it generated a new xorg.conf and I restarted laptop, but still could not run X window on LCD TV. Please correct me, but I thought if the xorg.conf is reconfigurated, it should work unless that the CentOS 5.2 does not support the type of Sony LCD? Thanks for your help. Kind regards, Jupiter
