I recently bought a 144hz monitor (Acer KG241QP - DP 1.2) and decided to run a dual monitor setup with my old 60hz monitor (BenQ VW2245Z - VGA cable with VGA to D-sub converter for the graphics card).
GPU - MSI R7 265 OC edition
The problem is whichever monitor I connect SECOND starts flickering (Vertically going out of display and constantly and flickering). If i boot my PC the old one (60hz) flickers while the 144hz one works fine and if I disable my primary 144hz one and then re-enable it from windows display settings the 144hz one starts flickering the same way while the 60hz one stops flickering at all.
I tried changing/lowering the resolution on the 60hz monitor and even increased its refresh rate to 75hz on the lower resolution but still the same problem occurs.
