为啥60hz显示器的刷新率有59hz和60hz两种选项？这两种 ...

很有意思的问题，先MARK

虽然我无法回答这个问题，但我也要反驳一下前面几个回答，他们说“没啥区别”，实际上在部分硬件上是有的，比如我家里的LG显示器（60hz），设为59hz后，每隔一段时间显示器就会闪一下，而60就不会，但是我办公室的另一个AOC（60hz）就不会，我猜应该是LG主控板严格执行60的刷新率，导致了和系统刷新率不同步，最终产生了周期性的闪烁，而AOC可能因为新的主控技术（国产一般比老牌大厂更开放），可以自动兼容两种刷新模式，所以不闪屏。

纯个人初步想法啊，期待大神来解释一下这个问题，困扰我很久了QAQ

用Deepseek满血版问问看

我觉得吧，没有什么影响。

在vista/server2008及以上的系统中，刷新率只保留整数部分，不四舍五入，所以有59HZ 60HZ两个选项。

本人亲测，

59HZ实际上是59.94HZ

60HZ实际上是60.00HZ

当年NTSC制式的模拟彩色电视信号为了避免干扰，把原来的场频60.00HZ下调为59.94HZ。

显示器设计59.94HZ是为了与NTSC 模拟彩色电视信号同步，这个是模拟时代的历史遗留问题

据说(未验证)，A卡有59.94/60.00，N卡只有59.94(设为60还是会跳回59)

转自XX百科：

In December 1953 the FCC unanimously approved what is now called the NTSC color television standard (later defined as RS-170a). The compatible color standard retains full backward compatibility with existing black-and-white television sets. Color information was added to the black-and-white image by introducing a color subcarrier of precisely 315/88 MHz (usually described as 3.579545 MHz or 3.58 MHz). The precise frequency was chosen so that horizontal line-rate modulation components of the chrominance signal fall exactly in between the horizontal line-rate modulation components of the luminance signal, thereby enabling the chrominance signal to be filtered out of the luminance signal with minor degradation of the luminance signal. Due to limitations of frequency divider circuits at the time the color standard was promulgated, the color subcarrier frequency was constructed as composite frequency assembled from small integers, in this case 5×7×9/(8×11) MHz.[11] The horizontal line rate was reduced to approximately 15,734 lines per second (3.579545×2/455 MHz = 9/572 MHz) from 15,750 lines per second, and the frame rate was reduced to 30/1.001 ≈ 29.970 frames per second (the horizontal line rate divided by 525 lines/frame) from 30 frames per second. These changes amount to 0.1 percent and were readily tolerated by existing television receivers.

PS：A-V一般是29.97/30.00/59.94/60.00

60的本意是“60.00Hz”

59的本意是“59.94Hz”

我的显示器是1366x768分辨率的

据我实验测得，59模式的刷新率也是60Hz

不过，1280x720分辨率的59Hz模式下画面是全屏拉伸

而60Hz模式下是点对点，带黑边

有的国家市电频率是60Hz吧，若显示器频率也是60Hz，在灯光下就会出现一种神奇的效果，59Hz就能没问题了。纯属个人见解，仅供参考。
