The GPU has to feed two display ports.
The only way to not drop FPS would be to use some HDMI SPLITTER.
I have read online that there are no performance drops while utilizing duplicate (clone) mode for a dual monitor setup. However, when I run games in clone mode I sometimes get heavy performance drops. It doesn't even happen with all games.
The monitors are the default of the laptop and an external tv connected via hdmi.
I have a gtx 1060 6gb and a i7-7700hq. the nvidia control panel doesn't recognize the second monitor even though it obviously displays just fine.
I always run at 60Hz, 1080p.
How can I fix this? I just want to duplicate the display without lagging. any help is appreciated.
