How do I configure or add custom resolution 1440x900 in guest PC?
Currently it allows me to go up to 1400x1050. I am using the latest version "VirtualBox-4.2.6-82870-Win".

Have you installed the guest additions (in the guest)?

What happens if you use the host+F toggle to go full screen?

It changed to 1920x1200. Still cannot set to 1440x900.

See Chapter 9.7 Advanced display configuration in your VirtualBox users manual.

I tried the command:

vboxmanage setextradata "VM Name" "CustomVideoMode1" "1440x900x32"

Powered on the VM, nothing changed. How or where do I see the new custom resolution?

vboxmanage setextradata "VM Name" "CustomVideoMode1" "1440x900x32"

Replace "VM Name" with the actual name

I did use my VM Name, which it is "Windows XP 32-bit"

With the guest running type this in the hosts terminal.
VBoxManage controlvm "Windows XP 32-bit" setvideomodehint 1440 900 32

hi all,

I had the same problems with different setup:

Host OS: Linux Mint 17 Cinnamon 64-bit
Guest OS: Centos 6.6
Virtualbox: Oracle VM VirtualBox Manager 4.3.10_Ubuntu

Solution which worked for me:

1. Install Virtualbox --> Devices, Insert Guest Additions CD image
Code: Select all   Expand viewCollapse view
    [root@centos6 ~]# cd /media/VBOXADDITIONS_4.3.10_93012/
    ./VBoxLinuxAdditions.run


2. get custom resolution string:
Code: Select all   Expand viewCollapse view
    [root@centos6 ~]$ cvt 1600 900
    # 1600x900 59.95 Hz (CVT 1.44M9) hsync: 55.99 kHz; pclk: 118.25 MHz Modeline "1600x900_60.00"  118.25  1600 1696 1856 2112  900 903 908 934 -hsync +vsync


3. set custom resolution string:
Code: Select all   Expand viewCollapse view
    [root@centos6 ~]$ xrandr
    Screen 0: minimum 64 x 64, current 1024 x 768, maximum 16384 x 16384
    VBOX0 connected 1024x768+0+0 0mm x 0mm
       1024x768       60.0*+   60.0*
       1600x1200      60.0 
       1440x1050      60.0 
       1280x960       60.0 
       800x600        60.0 
       640x480        60.0 

    [root@centos6 ~]$ xrandr --newmode "1600x900_60.00" 118.25  1600 1696 1856 2112  900 903 908 934 -hsync +vsync

    [root@centos6 ~]$ xrandr --addmode VBOX0 "1600x900_60.00"


4. use normal system administration config dialog to change resolution to 1600 x 900 which was not available before.

HTH,
Magnus
