Hi all, recently just upgraded my PC- finnaly after 9 years! anyway, everything build wise is fine, but i cannout output 144hz, the option is there but when i apply it, the screen flashes a few times and just resets back to 60hz. i have an msi 2070 and a benq xl2411 and previoulsy i ran 144hz on dvi-dl fine. i have purchased a bizlink active adaptor so i could run it properly. but nothing will not apply. unsure what to do and i have been sitting in a nvida live chat with no one.
