That's the driver board of your monitor, which supports a 17-inch front-screen display, not a 19-inch display, and you can refresh a driver that supports 19 inches.

It is caused by the mismatch between the motherboard of the display and the display screen, and it is useless to change the driver of the host. Only the motherboard of the monitor can be replaced.
