Hey there, Dan! If you're having issues changing the settings on your monitor, you'll want to check out their website or contact the manufacturer for them.

If you need help with the Xbox console, can you be a little more clear with what your asking so we can help you better? Look forward to seeing you post back if you do still need help.

Try changing your xbox 360 from 60 hz to 50 hz (in settings)

if the frequency is 50 Hz, the refresh rate you need to use is 50 Hz.

if you use 60 Hz it will not make any real differences but the correct refresh rate to use is 50 Hz.

i'm sorry your monitor will only except 60 Hz over HDMI

Monitors often choose less expensive internal electronics and use display port to make the computer do the work for them.

Real hardware to do real 120 Hz display, is very expensive. in fact many of the cheaper monitors only have 60 Hz panels but the hardware will accept the input and scale it down to 60 Hz from 120.
