A: boot " bang" sound when the display is internal degaussing circuit, which is one way to prevent the display is magnetized .

 

" Warning appears on my monitor is Samsung 743dfx, I'm using the driver that comes with the monitor , I was ready to be transferred to its refresh rate 85hz, but I pressed the" OK " : : Ask your already customized the video refresh rate. refresh rate is set incorrectly may damage the monitor ...... " can I be transferred to 85hz refresh rate it? This will damage the watch?

 

A: Samsung 743dfx 1024 × 768 resolution at the highest refresh rate of 85hz , therefore , raise the monitor refresh rate to 85hz not cause harm to the monitor. The warning appears normal, it is a normal warning message operating system. In addition, after setting a new refresh rate , if there is no black or jitter display properly , do not make the keyboard or mouse , for about 15 seconds, and the general operation of the system will be restored to the original normal refresh rate.
