Change resolution on monitor

HP Recommended
Microsoft Windows 10 (64-bit)

Hello everyone, I have 2 questions:

1. I bought a monitor (HP X24C) which has a 144 Hz refresh rate, that I use with my Omen laptop which has a 144 Hz refresh rate as well. I can't change the refresh rate of my monitor from 60 Hz to 144 Hz in the settings. When I try to do so the system tells me that the settings are not valid and that I should try with another combination. I mean, the monitor has the 144 Hz refresh rate and I cannot even use it? By the way, on the Quick setup guide of the monitor there is written that the optimum resolution is 1920x1080 @ 60Hz. I searched on Hp Store and I'm sure that this monitor has 144 Hz refresh rate. How can I do?

2. When I watch a video on Youtube , when I go to full screen, the video doesn't play on the monitor (when you are out of full screen, the video plays) and you can see only a frame. However this doesn't happen on the Laptop. This happens also with Netflix, where the movie doesn't play on the monitor. The most strange thing is that if I play a video which has a 1440p or upper resolution, it plays on the monitor on full screen as on the Laptop. The monitor hasn't any problem because I'm able to do every other activity. 

Please help me
