Resolution 1920x1080 pixelated

I am using a Nvidia GeForce GTX 470 graphics card with the proprietary nvidia driver.

When I set the resolution to something different than 1600x1200 pixels, all icons and fonts look pixelated. I would like to use the native resolution of 1920x1080 of which the Nvidia X Server Settings dialogue says is the best resolution.

My xorg.conf lokks like:

Section "ServerLayout"
    Identifier     "Layout0"
    Screen      0  "Screen0" 0 0
    InputDevice    "Keyboard0" "CoreKeyboard"
    InputDevice    "Mouse0" "CorePointer"
    Option         "Xinerama" "0"
EndSection

Section "Files"
EndSection

Section "InputDevice"

    # generated from default
    Identifier     "Mouse0"
    Driver         "mouse"
    Option         "Protocol" "auto"
    Option         "Device" "/dev/psaux"
    Option         "Emulate3Buttons" "no"
    Option         "ZAxisMapping" "4 5"
EndSection

Section "InputDevice"

    # generated from default
    Identifier     "Keyboard0"
    Driver         "kbd"
EndSection

Section "Monitor"
    Identifier     "Monitor0"
    VendorName     "Unknown"
    ModelName      "Samsung SyncMaster"
    HorizSync       26.0 - 81.0
    VertRefresh     24.0 - 75.0
    Option         "DPMS"
EndSection

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BoardName      "GeForce GTX 470"
EndSection

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    DefaultDepth    24
    Option         "TwinView" "0"
    Option         "metamodes" "1920x1080_60 +0+0; nvidia-auto-select +0+0; 1680x1050 +0+0"
    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection

Section "Extensions"
    Option         "Composite" "Enable"
EndSection

Re: Resolution 1920x1080 pixelated

If your system is up to date, you should set up your xorg like this https://wiki.archlinux.org/index.php/Xorg
If you followed the beginners guide to set up the xserver, that was for older versions of xorg. The new xorg is set up differently. It has different files under xorg.conf.d/
That is just something you could try. I am not really sure how to fix this. Also, you should make sure that you have the nvidia drivers installed correctly. https://wiki.archlinux.org/index.php/NVIDIA
Hope that helps. smile

Re: Resolution 1920x1080 pixelated

You should check the hardware to find the native resolution.  The Nvidia X Server Settings dialogue could be wrong.

Also, any fuzziness could be due to fonts, sub-pixel hinting, etc.

Re: Resolution 1920x1080 pixelated

The xserver and the nvidia driver are installed correctly. I have been playing around with the dimensions (of the screen in milimeter) as they were not recognized correctly, but this does not change anything.

And the hinting does not change the appearance of any icons, but only the font, isn't it?

Re: Resolution 1920x1080 pixelated

As Proofrific already said, make sure your monitor is actually 1920x1080. Especially if you're using HDMI, the nvidia driver can make the mistake of detecting that as the native resolution.

This is in your xorg.conf at the end of the modeline section:

1680x1050 +0+0

have you tried that?

Re: Resolution 1920x1080 pixelated

No change with editing the ModeLine.

What is really strange, when I use a vga adapter, the image I get on the screen is completely fine with the same settings.
