    I've looked through the posts and can't see any answer to my problem. I've purchased an Asus 16.8" LCD monitor with native resolution on 1366x768. When I hook it up I can't access this resolution in the AA1. I know the native resolution of the AA1 is 1400x600 or so, but I would think that a graphics card would have possible alternative resolutions, otherwise why provide a VGA input plug?

    Can anyone help with what resolutions can be achieved with the AA1, and/or whether I would need to hack a .conf or similar file with additional resolutions. If its the latter, can anyone help with how I go about it?

    Thanks for any help.

    I'd appreciate an answer on this too. I've got an Acer X223W 22" lcd monitor, with maximum resolution of 1680x1050. I have to go into Display Settings on startup to switch the display to external display only, which gives me the choice of 1024x600, which distorts vertically, or 1024x720 (at 3 different refresh rates) which is stretched horizontally. How I can set the screen resolution to one that displays better and preferably so I don't have to redo it every time? Just having more resolution choices in the display settings menu would be a better than nothing.

    Hi

    the relevant part of my /etc/X11/xorg.conf file: (try to uncomment the line beginning with #Virtual 2304 1024... and to comment the line before. Commenting= to erase the "#" sign, uncommenting= puting a "#" at the beginning of the line)

    -----------------------------------------------
    Section "Screen"
    Identifier "Screen0"
    Device "Videocard0"
    Monitor "Monitor0"
    DefaultDepth 24
    SubSection "Display"
    Viewport 0 0
    Depth 24
    Modes "1280x1024" "1280x800" "1024x768" "1024x600" "800x600" "640x480"
    Virtual 2048 1024 # let you have 2 monitors with 2 differents desktops, only up to 1024xx768 max
    #Virtual 2304 1024 # let you have 2 monitors with 2 differents desktops up to 1280x1024 but you won't have any video acceleration (no opengl!) because the frame buffer > 2048


    EndSubSection
    EndSection
    -----------------------------------------------

    Hope it helps

    Thanks The Tilde. Done that (you need to log in to root first) with the second virtual option, because I have a widescreen monitor (or have I misunderstood). Restarted, but no change and still no option in Display Settings for the new screen resolutions.

    How do I put them into effect?
    Cab I add a mode which has a different resolution such as 1680x1050 mentioned in my earlier post?

    Problem solved.
    1. Include "1680x1050" in the mode line as the first size
    2. On restart, DO NOT USE Display Settings
    3. Instead just use Fn F5 to toggle to the external monitor

    The standard desktop looks a little weird but other wise it all works fine. :)

    Re: External Monitor Resolution the easy way!

    There is no need to go to all that complexity to set the resolution on an external monitor. Just click on settings at the bottom right of the desktop and then go to the display icon and you can select available resolutions there. My AA1 has 1024x600 on its own screen but 1024x768 on my external monitor. Why make doing such a simple thing so complicated by command line editing things?

    I am confused by this problem also. I have AOD150 running XP. I have the same resolution for the netbook, but when I connect to an external monitor it will display the same resolution on the monitor with black bars on top and bottom under clone setting. If I switch to external only it reverts to the basic 640x840 with 32 bit color. My external monitor is an olevia 27" LCD that is HD. I have tried updating the chipset driver and the graphic driver from Acer download. Neither corrected the problem. Any advice or solutions would be greatly appreciated.
