How to set a very high screen resolution?

Post by Pixel-King »

Hello,

I'm new to the VirtualBox forum and also to VirtualBox itself. At first I have to excuse me for my bad english. I can understand it well, but I'm not really used to write and talk in english. My native language is german.

In the german Wikipedia, there is a statement concerning the maximum screen resolution. With guest additions, a resolution up to 64000 * 64000 pixel should be possible.

http://de.wikipedia.org/wiki/Virtualbox ... eiterungen

But I'm wondering, how I can set this huge resolution. In the guest operating system I can only set a maximum resolution up to 6400 * 1200 pixel. This works fine so far. But I would be glad, if I can set even a higher resolution, round about 16000 * 16000 for instance. Or is there a limit from MS Windows?

Can anybody help me, please? :-)

- Yes, I have installed the guest additions.
- The virtual graphics memory is set to the maximum of 128 MB.
- It doesn't matter, if I choose 32 Bit or 16 Bit colour depth.
- In the first try I took Win XP as host and guest. In the second try I took Win 7 Beta as host and guest. There was no difference in this effect.
- My VirtualBox version is 3.0.6.

Dou you need some other informations?

I thank you in advance!

As far as I've tested you can do this with RDP by editing the rdp file settings you can set any resolution, ea:

You could try this.

Code: Select all

VBoxManage controlvm VMNAME setvideomodehint 16000 16000 32

Oh, this is funny! With this solution I don't even have tu use VirtualBox. I can just connect to my second computer. But unfortunately in this way the resolution is limited to 4096 * 2048 pixel.

I tried it now. On the one hand, this doesn't cause a error message. On the other hand, it also doesn't cause any effect at all. In my guest Windows the settings are already limited to 6400 * 1200 Pixel.

As I forgot to tell: In the beginning I executed this command line:

Code: Select all

VBoxManage setextradata global GUI/MaxGuestResolution any
