QEMU can virtualize a few types of VGA hardware. Some examples are:
* *std*, the default, emulates a card with Bochs VBE extensions.
* *cirrus*, this was once the default, it emulates a very old hardware module
with all its problems. This display type should only be used if really

* *vmware*, is a VMWare SVGA-II compatible adapter.
* *qxl*, is the QXL paravirtualized graphics card. Selecting this also
enables SPICE for the VM.
You can edit the amount of memory given to the virtual GPU, by setting
the *memory* option. This can enable higher resolutions inside the VM,
the 'memory' option. This can enable higher resolutions inside the VM,
especially with SPICE/QXL.
Selecting Multi-Monitor mode for SPICE (e.g., qxl2 for dual monitors) has
some implications:
As the memory is reserved by display device, selecting Multi-Monitor mode
for SPICE (e.g., `qxl2` for dual monitors) has some implications:
* Windows needs a device for each monitor, so if your ostype is some
version of windows, {pve} gives the VM an extra device per monitor.
* Windows needs a device for each monitor, so if your 'ostype' is some
version of Windows, {pve} gives the VM an extra device per monitor.
Each device gets the specified amount of memory.
* Linux VMs, can always enable more virtual monitors, but selecting
a Multi-Monitor mode multiplies the memory given to the device with
the number of monitors.
Selecting *serialX* as display disables the VGA output, and redirects
the Web Console to the selected serial port. A configured memory setting
will be ignored in that case.
