Higher Resolution? Lag?

Is there any way to increase the resolution past option 5 to 2560x1440?

Also there's a lot of lag on display, especially when dragging or resizing windows. Is there a way to reduce lag?

@HenryDev - Can you try increasing the VRAM higher, maybe to 256 MB or even more? That would likely speed things up, and might allow higher resolutions. Though for resolution, that may be a hard limit for VirtualBox at this time... I'm pretty sure 4K+ isn't yet supported correctly.

@HenryDev I've tried running n=6 and higher but the resolution does not change from 1920x1200. I believe this is a limitation of VirtualBox. You can try assigning more video RAM if your host system is powerful enough. Note, you cannot assign more than 128MB in the GUI, you will need to use the following command line:

VBoxManage modifyvm "Name of VM" --vram 256
