|
|---|
| 10 | virtual graphics card available to the guest, in megabytes. As with the main memory, the
|
|---|
| 11 | specified amount will be allocated from the host's resident memory. Based on the amount of
|
|---|
| 12 | video memory, higher resolutions and color depths may be available. </p>
|
|---|
| 13 | <p>
|
|---|
| 14 | <ph conkeyref="vbox-conkeyref-phrases/vbox-mgr"/> will show a warning if the amount of video memory
|
|---|
| 15 | is too small to be able to switch the VM into full screen
|
|---|
| 16 | mode. The minimum value depends on the number of virtual
|
|---|
| 17 | monitors, the screen resolution and the color depth of the
|
|---|
| 18 | host display as well as on the use of <i>3D
|
|---|
| 19 | acceleration</i> and <i>2D video
|
|---|
| 20 | acceleration</i>. A rough estimate is
|
|---|
| 21 | (<i>color depth</i> / 8) x <i>vertical
|
|---|
| 22 | pixels</i> x <i>horizontal pixels</i> x
|
|---|
| 23 | <i>number of screens</i> = <i>number of
|
|---|
| 24 | bytes</i>. Extra memory may be required if display
|
|---|
| 25 | acceleration is used.

| 29 | <p><b outputclass="bold">Monitor Count:</b> With this
|
|---|
| 30 | setting, <ph conkeyref="vbox-conkeyref-phrases/product-name"/> can provide more than one virtual
|
|---|
| 31 | monitor to a virtual machine. If a guest OS supports
|
|---|
| 32 | multiple attached monitors, <ph conkeyref="vbox-conkeyref-phrases/product-name"/> can pretend that
|
|---|
| 33 | multiple virtual monitors are present. Up to eight such
|
|---|
| 34 | virtual monitors are supported.
|
|---|
| 35 | </p>
|
|---|
| 36 | <p>
|
|---|
| 37 | The output of the multiple monitors are displayed on the
|
|---|
| 38 | host in multiple VM windows which are running side by side.
|
|---|
| 39 | However, in full screen and seamless mode, they use the
|
|---|
| 40 | available physical monitors attached to the host. As a
|
|---|
| 41 | result, for full screen and seamless modes to work with
|
|---|
| 42 | multiple monitors, you will need at least as many physical
|
|---|
| 43 | monitors as you have virtual monitors configured, or
|
|---|
| 44 | <ph conkeyref="vbox-conkeyref-phrases/product-name"/> will report an error.
|
|---|
| 45 | </p>
|
|---|
| 46 | <p>
|
|---|
| 47 | You can configure the relationship between guest and host
|
|---|
| 48 | monitors using the <b outputclass="bold">View</b>
|
|---|
| 49 | menu by pressing Host key + Home when you are in full screen
|
|---|
| 50 | or seamless mode.

|

| 58 | scaling of the display size. For multiple monitor displays,
|
|---|
| 59 | you can set the scale factor for individual monitors, or
|
|---|
| 60 | globally for all of the monitors. Use the slider to select a
|
|---|
| 61 | scaling factor up to 200%.
|

|

| 63 | <p>
|
