Thanks man for your information, very valuable. I own the PG279Q and I love it, I have always used it with the 144Hz settings that came from factory, never tried to overdrive it up to 165Hz cause read some information about weird stuff I could experience, seems this weird stuff is the inverse ghosting, so my questions are: is it safe to OD up to 165HZ?, I use the monitor for gaming, is it going to benefit me after I OD it?, and finally, If I try the OD up to 165Hz and I dont like it, can I always go back to the 144Hz factory settings?, thanks in advance for your information and tips!
