频宽(Bandwidth)是一种衡量显示器显示性能的方法.频宽的单位为MHz,是指每秒在每条线上显示的点数.更严格地说,频宽是指系统在点之间的频率反应.这些点是信号强度落在其最大值的特定百分比的地方(通常是50%～70%).原则上,频宽愈大,显示器愈好,尽管显像管的品质经常是影响显示性能的限制因素,但很多标准的显示器还是很少把频宽加大到超过某一个点.现有的显示器标准频宽如:VGA显示器18MHz,VGA+显示器 35MHz,CAD显示器 100MHz.
Bandwidth is a measure of the display performance of a monitor. The bandwidth in MHz is the number of dots displayed per line per second. More strictly, the bandwidth is the point at which the system is between points Frequency Response These points are where the signal strength falls within a certain percentage of its maximum value (usually 50% to 70%). In principle, the larger the bandwidth, the better the display, although the quality of the picture tube often affects display performance Limiting factors, but many standard monitors rarely increase the bandwidth beyond a certain point. Existing monitors have standard bandwidths such as VGA monitor 18MHz, VGA + monitor 35MHz and CAD monitor 100MHz.
