What is: VGA SVGA XGA SXGA

VGA can often be seen in these terms, usually these important technical indicators refer to the resolution of the LCD screen (TFT LCD). TFT is the abbreviation of English thin Film transistor, Chinese meaning is thin film transistor.

The VGA (Video Graphics Array) is a computer display standard that IBM introduced in 1987 to use analog signals, a standard that has become obsolete for today's PC market. Even so, VGA is still a low standard supported by the largest manufacturers, and the PC must support the VGA standard before loading its own unique driver. For example, the boot screen of the Microsoft Windows family of products still uses the VGA display mode, which also indicates the lack of resolution and the number of load color.


The term VGA is often used regardless of its graphic device and is directly applied to the resolution of the reference 640x480. The VGA device can store up to 4 full EGA colors at the same time, and they can be quickly converted between them, and they look like instant discoloration on the screen.

The LCD screen with a general resolution of 1024x768 or 800*600 is called XGA,
The LCD screen with 1400*1050 resolution is called SXGA,
The LCD screen with 1600*1200 resolution is called UXGA,
LCD screens with resolution 1024*480 or 1280*600 are called UWXGA (e.g. Sony's C1 series),
The LCD screen with 1024*512 resolution is called WXGA

VGA, SVGA, XGA, SXGA, UXGA are the different resolutions of the term, specifically as follows:

XGA 1024x768 15.1 ", 14.1", 13.3 ", 12.1", 11.3 ", 10.4"
TFT/SVGA 800x600 12.1 "
sxga+ (SXGA) 1400x1050 15 ", 14.1"
UXGA 1600x1200 "IBM a22p display

Non-standard specifications:
UWXGA 1024x480 8.9 "SONY C1 Series
WXGA 1024x512 8.8 "FUJITSU P1000. 1152x768 15.2 "Apple PowerBook G4


Note: The resolution of the projector can be divided into VGA, SVGA, XGA, SXGA and UXGA.


The resolution of the projector is inseparable from the connected computer. There are several standards for computer resolution:


VGA (640x480)
SVGA (800x600)
XGA (1024x768)
SXGA (1280x1024)
UXGA (1600x1200)
QXGA (2048x1536)
