VESA BIOS Extensions（简称VBE）是VESA制定的标准。由其可以利用进程通过显示卡设置显示器的分辨率，色彩字节数。最新版为1998年制定的VBE 3.0。

该标准由传统调用中断10H（INT10H）的方式扩展而来。中断是从前计算机外部设备的进程接口，分配给显示器中断接口为10H。调用中断使用不同的参数可以将显示器分辨率设置为320x200，640x400，640x480，800x600，1024x768，1280x1024。将颜色字节数设置成为4bit,8bit,16bit,24bit,32bit。以及帧内存访问模式和地址，RAMDAC的设置。

VESA BIOS Extensions (VBE) is a VESA standard, currently at version 3, that defines the interface that can be used by software to access compliant video boards at high resolutions and bit depths. This is opposed to the "traditional" int 10h BIOS calls, which are limited to resolutions of 640×480 pixels with 16 color (4-bit) depth or less. VBE is made available through the video card's BIOS, which installs during boot up some interrupt vectors that point to itself.
