Here are some ways to detect light leakage in a computer monitor:

1.Black screen test:Turn the monitor to its brightest and turn the screen to black. In a dark room, observe the edges of the monitor for light or bright spots. If there is, then this is a light leak.

2.White Screen Test:Turn the monitor to its darkest and turn the screen to full white. In a dark room, observe the edges of the monitor for darkness or dark spots. If there is, then this is a light leak.

3.Look at the edge of the display:In a dark room, observe the edges of the monitor for light or bright spots. If there is a sock, then this is a light leak.

4.Look at the corner of the monitor:In a dark room, observe the corners of the monitor for light or bright spots. If there is a losing round, then this is a light leak.

5.Viewing angle inspection: Change the viewing angle and observe the monitor screen from different angles and positions to determine if there are areas of light leakage.

If significant areas of bright light leakage are observed during the above steps, especially against a black background, there may be a light leakage problem. Please note that moderate backlight leakage may be normal in some cases, but if the leakage area is too noticeable or interferes with normal use, it may be necessary to consider contacting the manufacturer or after-sales service provider for further service or repair.
