我问的原因是因为我刚买了一个新的 LCD，在显示模式之间切换大约需要 5 秒，例如从 1920x1080x32bpp 到 1280x800x32bpp。是否存在用于检测显示器是否已准备好进行视频输出的编程解决方案？

I believe the answer is 'no'. Once the display adapter starts transmitting a new signal in a new refresh rate, etc., it has absolutely no way of knowing how long it takes the display to internally process the change and start showing an image. This is a hardware limitation with both DVI and VGA signals, not a software one.
