Both VGA and DVI are video transmission lines. The former is the traditional analog transmission, the latter species is more, there is only the transmission of digital or analog or digital mode is transmitted, in short, the latter video signal transmission quality is higher than the former, and transmission speed faster.

What are the differences between VGA, DVI, RS232, UART, SCSI, SATA, and other interfaces?Both VGA and DVI are video transmission lines. The former is a traditional analog transmission, and the latter has many types, which only transmits numbers or analog or digital models. In short, the latter's video signal transmission quality is higher than the former, and the transmission speed is faster. At present, many monitors on the market use DVI interfaces (including HDMI, HDTV, And the
The NVIDIA 337.12 beta driver Linux support version was recently released. The following GPU support is added: geForce 830 M, GeForce 840 M, GeForce 845 M, GeForce GTX 850 M, GeForce GTX 860 M, GeForce GTX 870 M, GeForce GTX 880 M, GeForce GT 705, GeForce GT 720, there are also some new features and fixes.
One problem that causes OpenGL program to crash is solved. NVIDIA settings have been updated to support DisplayPort 1.2 display, and the NVIDIA set

Since 330MHz is the maximum pixel rate supported by a double-stranded DVI or DisplayPort of the video card, the active stereo fusion resolution of the single-port input multichannel output supported by the large-scale electronic fusion device can be obt
