Was exchanging this monitor or calling the maker.
http://www.p4c.philips.com/cgi-bin/cpindex.pl?ctn=243V5LHAB/00&hlt=Link_UserManuals&mid=Link_UserManuals&scy=EE&slg=AEN didn't give me any new ideas as I read the manual.
But at http://www.p4c.philips.com/cgi-bin/cpindex.pl?ctn=243V5LHAB/00&hlt=Link_Software&mid=Link_Software&scy=EE&slg=AEN I do see a drivers (most likely the MONITOR.INF) that should be installed.
I recently bought a new pc containing a i5 6600 and gtx 1060 6gb (by gigabyte).
I have a phl 243v5 1920xq080 60hz monitor (philips). It starts blinking while playing games (only). All drivers are up to date and it didn't have any issues with my old pc with sapphire 7850 card.
I plugged another monitor with same resolution and 60hz by lg and it worked like a charm.
What could be the problem?
What i tried to do:
Reconnecting ram cards
Playing with lower resolution (didnt help)
Turning off the power saver option
