I am familiar with the understanding that higher bit rate may/can affect or make for a higher quality/better appearing
video appearance. I would like to see/create some examples so that I could compare them and see the difference though.

I am limited to viewing 1920x1080 resolution video clips - my monitor is maxed out at this setting - Dell SR2220L(HDMI). Does this limit me in how well or if I can even view/see the difference bit rate makes on video clips?

I think I have to use video clips that have movement in them like previously stated, leaves oscillating in the wind - moving water over riffles - may be the sort of video subject where I can see the difference better. So with a 1920x1080/60p clip - and using trees/leaves blowing in the wind or water flowing over riffles - I should see really obviously the difference in 15Mbps and 60Mbps correct?

'Everyday video', I understand seeing this difference may be more difficult to see.
