Question about Club 3D Mini DisplayPort — Mini DisplayPort

I have the following setup: 2 monitors Acer XB271HU, graphics card Geforce GTX 980 Ti, Windows 10. I cannot manage to drive both monitors at 144 Hz. I can get one to 144 Hz, but the other stops at 85 Hz. Is it possible that it's the DisplayPort cables? I use the cables that came with the monitors. They're probably not the best quality... Could this cable help?
