monitor native resolution not displayed properly

2243sn samsung monitor 22 "1920x1080 native resolution

Fedora 10 does not recognize recognise the monitor properly and offers a maximum resolution of 1440x1050
system-config-display has the same thing
both believe that it's a 17 "monitor

I tried to GTF 1920 1080 60 and added edited the xorg.conf

Code:

# Xorg configuration created by system-config-display

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

Section "InputDevice"

# Keyboard added by rhpxl
    Identifier "Keyboard0"
    Driver "kbd"
    Option "XkbModel" "pc105"
    Option "XkbLayout" "ee"
EndSection

Section "Monitor"

    Identifier "Monitor0"
    Modeling "1920x1080_60.00" 172.8 1920 2040 2248 2576 1080 1081 1084 1118-hsync + vsync [/ b]
EndSection

Section "Device"
    Identifier "Videocard0"
    Driver "intel"
EndSection

Section "Screen"
    Identifier "Screen0"
    Device "Videocard0"
    Monitor "Monitor0"

    SubSection "Display"
       Viewport 0 0
       Depth 24
Modes "1920x1080_60.00"
    EndSubSection
EndSection

now i can choose 1920x1080 but there are black bars on either side,(the image is compressed in the middle)

system-config-display still does not recognize that it is a 22 "monitor,
the changes i make dont stick, after rebooting it still has the monitor as "unknown" despite me having picked generic 1920*1080 lcd

How to get the native resolution to fill the entire screen?

Try adding the screen size with the "DisplaySize" option in the "Monitor" section of xorg.conf. You'll need the width X height of your screen.

eg (don't use these values):

Code:

DisplaySize    397 317

is that in pixels or cm ?

i added

Code:

Section "Monitor"

	# 1920x1080 @ 60.00 Hz (GTF) hsync: 67.08 kHz; pclk: 172.80 MHz
	Identifier   "Monitor0"
	ModeLine     "1920x1080_60.00" 172.8 1920 2040 2248 2576 1080 1081 1084 1118 -hsync +vsync
DisplaySize    1920 1080
EndSection

but the bars persist

Measurements are in millimeters.

ok, measured it by hand and got 480 x 270

edited the monitor section:

Code:

Section "Monitor"

	# 1920x1080 @ 60.00 Hz (GTF) hsync: 67.08 kHz; pclk: 172.80 MHz
	Identifier   "Monitor0"
	ModeLine     "1920x1080_60.00" 172.8 1920 2040 2248 2576 1080 1081 1084 1118 -hsync +vsync
DisplaySize    480 270
EndSection

but the black bars are still there
