Shows a 60hz Monitor.
Even the RL2455HM is a 60hz monitor.
Which would explain why there is no setting in your monitor's OSD.
Have you tried going into your monitor settings to see if 144 is enabled? That should be your first step.
Not your monitor settings in Windows.
Using your actual monitor buttons and OSD to see if it's enabled.
