Hey guys!
So basically I've had my G750JS for about two months and recently I have been working on some intense modelling/rendering where all of a sudden i started experiencing screen flickering. I'm not too sure whether it is the 3d modelling software which is causing the flickers but I think I have fixed it for now...
Anyways..what I found to work for the G750 JS models is changing the refresh rate from 60hz to 40 hz. You can do this by right-clicking the desktop and going to "screen resolution". From there click on "Advanced Setting"- "Monitor" and changing the refresh rate from 60 to 40.
For the past few days i have been flicker free and hope this solution works for others in similar situations! Also changing from 60 to 40 doesnt seem to affect any visual aspect of laptop. At least not in terms of 3d modelling....I dont know about gaming though.
Best of Luck!
