I can get to this refresh rate using:
Modeline "2560x1440_120" 462.84 2560 2624 2640 2660 1440 1442 1444 1450 +hsync -vsync
But i see artifacting. The higher pixel clock timings are a lot worse. Is it possible that it's the cable? I noticed that the monoprice ones are thicker. I'm currently using the one that came with the monitor.
edit: this is a bit better:
Modeline "2560x1440_120" 459.89 2560 2608 2640 2652 1440 1441 1442 1445 +hsync -vsync
it does have issues with gradiants though.
