Why does the Xiaomi Monitor A24i have color stripes when taking photos with a mobile phone/camera?

Question

Accepted Answer

If you notice color stripes on the Xiaomi Monitor A24i while taking photos or recording videos, this is a normal physical phenomenon known as moire patterns. Almost all monitors can produce this effect when captured by a camera due to differences in refresh rates between the display and the camera.
To better understand the cause, please refer to the following information:
1. A video is composed of a sequence of images taken at specific time intervals. Ordinary videos are recorded at around 30 frames per second.
2. When the camera’s shutter frequency does not match the monitor’s refresh rate, it captures the screen in a way that shows alternating lines or stripes. This creates the visual effect of color stripes in your photos or videos.
3. To reduce or eliminate the stripes, adjust your camera or phone settings to match the monitor’s refresh rate. This can minimize the frequency mismatch and produce clearer images without visible stripes.
