Avoid internal screen CRT monitor can burn and burn because of long-term work for the LCD is also true, so be sure to pay attention to, full color led display, if not in use, be sure to turn off the monitor, or reducing the display brightness of the display, led display manufacturers, or a long time, will lead to burn out or aging. This event is permanently damaged and can not be undone. In addition, if time to display a fixed content, Yidu led display, it may cause some LCD pixels overheat and cause internal burns. Brightness: generally set at 60-80. Too bright easily lead to eye fatigue, but also the use of phosphors premature aging. Contrast: generally set at 80-100. Refresh rate: If less than 70HZ, will feel flashes, set the computer's refresh rate increase. That field frequency refresh rate refers to the number of times per second the screen repeatedly drawn to HZ units. The higher the refresh rate, the more stable the screen display, the less light flashes. Most people's eyes to 75HZ refresh rate above the basic feel flicker, 85HZ above is no light flashes, indoor led display, so VESA Video Association International 85HZ flicker-free progressive scan formulate standards. CRT TV's refresh rate is only 50HZ, computer output to the monitor's refresh rate is the lowest 60HZ, 85HZ or 75HZ is recommended refresh rate. Do not put the monitor refresh rate is set at the upper limit should be a slightly lower grade than the highest refresh rate. Because when the monitor is working at the limit state, prone to aging circuit elements and cause damage. led display control software, 金锐光 electricity (online consultation), Yidu led display provided by the Science and Technology Co., Ltd.
