Change the resolution to 1080P or the recommended resolution. NOTE ⮹ Vertical frequency In order to display an image, the screen must be refreshed dozens of times per second, like a fluorescent lamp. The number of times the screen is refreshed per second is called vertical frequency, or refresh rate, and is represented by Hz. ⮹ Horizontal frequency The time it takes to display one horizontal line is called the horizontal cycle. If 1 is divided by the horizontal interval, the result is the number of horizontal lines displayed per second. This is called horizontal frequency and is represented by kHz. ⮹ LED can be lighted with Set OSD Menu. Menu – General – Power LED – On
