8	EFI provides two distinct video interfaces: GOP (Graphics Output
9	Protocol) and UGA (Universal Graphics Adapter). Modern OSes,
10	such as Mac OS X, generally use GOP, while some older ones still
11	use UGA. <ph conkeyref="vbox-conkeyref-phrases/product-name"/> provides a configuration option to
12	control the graphics resolution for both interfaces, making the
13	difference mostly irrelevant for users.
14	</p>
15	<p>
16	The default resolution is 1024x768. To select a graphics
17	resolution for EFI, use the following
18	<userinput>VBoxManage</userinput> command:
19	</p>
20	<pre xml:space="preserve">VBoxManage setextradata "VM name" VBoxInternal2/EfiGraphicsResolution HxV</pre>
21	<p>
22	Determine the horizontal resolution H and the vertical
23	resolution V from the following list of default resolutions:

338	If this list of default resolution does not cover your needs,
339	see <xref href="customvesa.dita">Custom VESA Resolutions</xref>. Note that the color depth
340	value specified in a custom video mode must be specified. Color
341	depths of 8, 16, 24, and 32 are accepted. EFI assumes a color
342	depth of 32 by default.
343	</p>
344	<p>
345	The EFI default video resolution settings can only be changed
346	when the VM is powered off.
