My main card is 780ti and monitor is XL2420G - gsync works perfectly when only this card is present BUT when I install another non-gsync card (gt 640 or 750ti with no display port) into the system, with gsync on the screen flickers like crazy constantly in all the drivers I've tried and in both windows 8.1 and windows 10 - clean install doesn't make a difference. Is this a bug or limitation with G-sync technology? Please can you help?
I dont think they tested low end cards Whell i some had money for gsync monitor so he have money for modern card And yea i think its nvidia mistaff
remove the driver with DDU and install again ( if you didn't already ) check the cable it could be damaged , remove your GPU and install it again ( your PC should be off and power supply isn't plugged to power socket )
I've done all that, apparently its a driver bug according to user on nvidia forums, just found out, last driver that works is supposed to be 337.88 so going to try, seems like a weird bug and wonder why it hasn't been fixed for so long...I'll try and report back.
I've got an Acer XB270H Gsync Monitor and I've not experienced this problem and I ran a 750ti along with my 980, Gsync functions as it should, I even have my integrated Intel Graphics enabled with my projector connected to it along with the 980 and the 750 TI with zero problems, Gsync just works, sounds like it could be a power issue, perhaps your PSU isn't up to running two cards together, if not that then possibly a motherboard issue, or maybe there's something wrong with your screen, or if it is a bug it might not be effecting every gsync monitor.
yeah the 750ti had a displayport but I've ran a geforce 460 which has no displayport as a dedicated physx card before I upgraded to 750ti and Gsync still functioned normally.
Well I just tried 337.88 and it works! So a bug that's been unsolved for over a year remains unsolved for some reason, maybe because it can't be replicated in nvidia labs? I wish I can help
