Samsung LCD resolution doesn't fit


Hi
I'm am quite new in linux, however after converting to Red hat at my job, I thought that I'd convert at home as well...however I found Ubuntu more attractive, so I've installed Ubuntu Feisty...
Now everything seems to work...but...I was considering to use my linux box as mediacenter and have plugged in my Samsung LE-32M51 LCD screen HDMI(TV)-DVI(PC). The picture is clear but the resolution is too big, though it's only set to 800x600. The screen ought to eat 1366x768, but it doesn't work. I've been searching the web for solutions and tried to edit the xorg.conf several times. Nevertheless it keeps being too big, no matter what resolution I choose...now after two weeks of struggle I have to consult some experts ;-) cause I'm totally out of ideas. My computer is an Asus Pundit P1-PH1 with an ATI X200 chipset. When I was running Windows, there was no problems with the LCD, so I've concluded that it can work in linux too, but I'm just too ignorant to find the way.
Below is part of my xorg.conf. I've added my TFT XA7-17i and my Samsung LCD monitor. First one is working perfect.
Does anyone have suggestions or even solutions?

Install the rpmforge-release package as per: http://dag.wieers.com/rpm/FAQ.php#B
Also install the yum rpm package and dependencies: http://dag.wieers.com/rpm/packages/yum/

When ready do: yum install dkms

Then install the ati-x11-drv for your system from here:

http://zod.freshrpms.net/rpm.html?id=1184
You will need the kernel-devel and kernel-header rpm packages installed.

rpm -Uvh ati-x11-drv*.rpm

Note: this is for RHEL5 only, for RHEL3/4 visit: http://ati.amd.com/support/drivers/l...ux-radeon.html

You will have to reconfigure your /etc/x11/xorg.conf file, example below;

Code:
# Xorg configuration created by system-config-display

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

Section "Files"
EndSection

Section "Module"
	Load  "dri"
	Load  "extmod"
	Load  "glx"
EndSection

Section "ServerFlags"
	Option	    "AIGLX" "off"
EndSection

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

Section "InputDevice"
	Identifier  "Synaptics"
	Driver      "synaptics"
	Option	    "Device" "/dev/input/mice"
	Option	    "Protocol" "auto-dev"
	Option	    "Emulate3Buttons" "yes"
EndSection

Section "Monitor"

 ### Comment all HorizSync and VertSync values to use DDC:
	Identifier   "Monitor0"
	ModelName    "LCD Panel 1280x800"
	HorizSync    31.5 - 90.0
	VertRefresh  59.9 - 60.1
	Option	    "dpms"
EndSection

Section "Device"
	Identifier  "Videocard0"
	Driver      "fglrx"
	Option	    "Centermode" "off"
EndSection

Section "Screen"
	Identifier "Screen0"
	Device     "Videocard0"
	Monitor    "Monitor0"
	DefaultDepth     24
	SubSection "Display"

		Modes "1366768" "1280720" "1024576" "854480" "1280x1024" "1024x768" "800x600" "720576" "640x480"
	EndSubSection
EndSection
