I have a very specific use case. I run a couple browser windows for stock portfolio/trading. I have various other windows, and most importantly I run CNBC in either a JRiver, or WMC window simultaneously.
If you run 30HZ you drop half the TV frames. TV is unwatchable at 30P. Running at 1080P cause the TV to scale and that TV does not scale well. I just felt it was important that people needing 4K60 444 not be confused by your post. I think you cleared it up.
