Hi Eugenio,
yes, it is possible to use a custom virtual screen size without even recompiling the framebuffer, but you have to edit the kext configuration.

Just do this:
– open the Terminal
– type “sudo su”, enter, type your password
– type “cd /System/Library/Extensions/EWSyphonProxyFramebuffer.kext/Contents/”
– type “nano Info.plist”
– search this section:
MaxResolution

height
1024
width
1280

and replace max height and width as you need to

– a little above this section you’ll find a list of available resolutions. Add yours:

height
2048
name
2048×768
width
768

– type “Ctrl+X” to save your editing

– now, back in terminal, you have to repair permissions for the driver you’ve just modified. Type:
“sudo chmod -R 755 /System/Library/Extensions/EWSyphonProxyFramebuffer.kext”
“sudo chown -R root:wheel /System/Library/Extensions/EWSyphonProxyFramebuffer.kext”

– delete the kext cache (“rmdir -R /System/Library/Caches/com.apple.kext.caches/Startup”);

– reboot

Let me know if everything went ok,
a.
