I just bought a second 144hz monitor. Both monitors are set to 144hz but when i set multiple displays to 'Extend these displays', 'Show only 1' or 'Show only 2' it only shows 65 fps on UFO test. However, when i set it to 'Duplicate these displays' they both show 144 fps. Does anyone know why this is happening and if there is a way to fix it. I have gtx 1050 ti.
