| 7 | <p>EFI provides two distinct video interfaces: GOP (Graphics Output Protocol) and UGA (Universal Graphics Adapter). Modern OSes, such as Mac OS X, generally use GOP, while some older ones still use UGA. <ph conkeyref="vbox-conkeyref-phrases/product-name"/> provides a configuration option to control the graphics resolution for both interfaces, making the difference mostly irrelevant for users.</p>
|
|---|
| 8 | <p>The default resolution is 1024x768. To select a graphics resolution for EFI, use the following
|
|---|
| 9 | <userinput>VBoxManage</userinput> command: </p>
|
|---|
| 10 | <pre xml:space="preserve">VBoxManage setextradata "VM name" VBoxInternal2/EfiGraphicsResolution HxV</pre>
|

| 11 | <p>Find the horizontal resolution H and the vertical resolution V from the following list of default resolutions: <table frame="all" rowsep="1" colsep="1">
