In the video, a man is seen holding a device in his hand and pointing it towards a laptop screen. The device appears to be a thermometer, and the man is using it to measure the temperature of the laptop screen. He then proceeds to press a button on the device, which causes the temperature reading to change. The man continues to hold the device and observe the temperature readings, occasionally pressing the button to adjust the settings. The laptop screen is visible in the background, and the man's actions suggest that he is testing the temperature of the screen for some purpose.
