So i have the Asus ROG Swift PG278QR 27 monitor.

And out of the box it comes at 144 hz. But it can be overclocked to 165 hz.

But when i bought the monitor, some of the employees at the computer section told me to not overclock it.
As "it may damage it"

Is it safe to overcloc this monitor or should i let it be in 144 hz and giving it the longest lifespan???
