My Lenovo ThinkPad's built-in screen maxes at 1366x768x32. I wanted to use that same resolution with Windows 8 Developer Preview inside of VirtualBox. So what did I do? - Downloaded the latest build of [VirtualBox][1] v4.1.6 (because it supports Windows 8 x64). - Installed Windows 8 Developer Preview in VirtualBox as I did earlier this year. - Installed Guest Additions. - Ran the CustomVideoMode described in this [blog post][2]. …and quickly found out that I didn’t have the option to use 1366x768x32 inside of VirtualBox despite using the following command: VBoxManage.exe setextradata "[Virtual Machine Name]" CustomVideoMode1 1920x1080x32 So how do you fix it? If you do a little research on this resolution then you will find it is a non-standard resolution. Even if you run the command: VBoxManage.exe setextradata "[Virtual Machine Name]" CustomVideoMode1 136**6**x768x32 It will still not show that resolution inside of VirtualBox. You can fix this easily by using the following command as shown below: VBoxManage.exe setextradata "[Virtual Machine Name]" CustomVideoMode1 136**0**x768x32 ![alt text][3] I hope that you noticed the command used the resolution of 1360 instead of 1366. Now if you go to your display option for Windows 8 inside of Virtualbox then you can select that resolution. ![alt text][4] Anyways I hope this helps someone with a similar problem. I created this blog partially for myself but it is always nice to help my fellow developer. Thanks for reading.
