Y'all can't see this with your optics, at least if it's properly adapted, but your camera can come across information technology, resulting in night bands or bare sections of the screen.
In the instance of beefy erstwhile CRT monitors, the refresh rate is usually at least 60 times per second. If the shutter speed on your camera is faster than the refresh rate, you risk capturing part or even none of the image. A similar thing can happen with LCD screens as the pixels refresh, oft creating a herringbone pattern. All the same, LCDs often take a faster refresh rate. This allows for a faster shutter speed.
If possible, look up the refresh rate in your transmission. If you know the refresh charge per unit, y'all can decide your maximum shutter speed.
ii. Choose Your Photographic camera Settings
It'southward possible to get a good shot of a screen in motorcar mode, but for best results, yous'll demand to control some or all of your camera settings.

You may discover in that location is a subtle banded pattern over the image of the screen. This is called "moire," and it'southward a common problem with this type of shot. You tin can minimize information technology past taking the photo at a few different distances. Try three feet, 4 feet, and five feet if your equipment and space allow.
If yous are running into issues with moire, you tin can also try adjusting the angle of your shot. Very slightly tip the photographic camera up or down or endeavour taking a one-half step to one side or the other. The beauty of digital is you tin can try lots of things to go the perfect shot.
