    Widescreen display problem on rhel5

    I am new to this forum. I am a both rhel5 and fedora user.I can not configure my Samsung syncmaster 632nw monitor to display full screen at 1360X768.There is huge blank space on left and right portion of the monitor.The maximun resolution is 1024*768 and minimum is 640*480.
    I have tried many times to solve it using xorg.conf but still unable to do it.Here is xorg.conf's content :

    # Xorg configuration created by system-config-display

    Section "ServerLayout"
    Identifier "single head configuration"
    Screen 0 "Screen0" 0 0
    InputDevice "Keyboard0" "CoreKeyboard"
    EndSection

    Section "InputDevice"
    Identifier "Keyboard0"
    Driver "kbd"
    Option "XkbModel" "pc105"
    Option "XkbLayout" "us"
    EndSection

    Section "Monitor"

    Welcome to the forums!

    Are you running the generic video drivers, or are you using the official nvidia drivers?

    Also, are you sure your video card is capable of displaying that resolution?

    Replace xorg.conf file with new one.
    Execute this
    Code:
    cd /etc/X11
su -
mv  xorg.conf xorg.conf.bak
nano xorg.conf
    Paste these contents :
    Code:
    Section "InputDevice"
	Identifier	"Generic Keyboard"
	Driver		"kbd"
	Option		"CoreKeyboard"
	Option		"XkbRules"	"xorg"
	Option		"XkbModel"	"pc105"
	Option		"XkbLayout"	"us"
EndSection

Section "InputDevice"
	Identifier	"Configured Mouse"
	Driver		"mouse"
	Option		"CorePointer"
	Option		"Device"		"/dev/input/mice"
	Option		"Protocol"		"ImPS/2"
	Option		"ZAxisMapping"		"4 5"
	Option		"Emulate3Buttons"	"true"
EndSection

Section "Device"
	Identifier	"Configured Video Device"
	Driver		"vesa"
	BusID		"PCI:1:0:0"
EndSection

Section "Monitor"
	Identifier	"Generic Monitor"
	Option		"DPMS"
	HorizSync	30-71
	VertRefresh	50-160
EndSection

Section "Screen"
	Identifier	"Default Screen"
	Device		"Configured Video Device"
	Monitor		"Generic Monitor"
	DefaultDepth	24
	SubSection "Display"
		Depth		24
		Modes		"1280x1024" "1024x768" 
	EndSubSection
EndSection

Section "ServerLayout"
	Identifier	"Default Layout"
	Screen		"Default Screen"
	InputDevice	"Generic Keyboard"
	InputDevice	"Configured Mouse"
EndSection
    Save file ( Press Ctrl+X, Y and hit Enter key ) and reboot machine.
    It is amazing what you can accomplish if you do not care who gets the credit.

    Add Monitor Section as suggested earlier.
    Check your Monitor's Manual and replace HorizSync and VertRefresh rates with supported rates.
    Code:
    Section "Monitor"
	Identifier	"Generic Monitor"
	Option		"DPMS"
	HorizSync	30-71
	VertRefresh	50-160
EndSection
