I have bought a new monitor to use with my notebook. once I connect it, my omen 15 starts to boost fans and lags extremely. I cannot even watch youtube videos, loses graphics and sound synchronizing. the monitor is viewsonic XG2405-2 model. I tried to try use it with different notebooks, it works perfect with other notebooks.
I tried to update drivers, they are all updated. I tried some suggestions here from former topics.
