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

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