A:AnswerThe laptop screen is 360hz compare to your external 144hz screen. You are not able to run any games with laptop screen and external screen on. You will need to shut the laptop lid and run it off one monitor or buy a new monitor that has 360hz.
A:AnswerThis does run off 360hz and seen a big difference between a 144hz and this 360hz screen as long you turn on the Mux switch and run the laptop directly off the graphics card. This will get you to 360hz. Most laptops that have 240hz but does not have G-Sync or a mux switch will not hit 240hz due to Optimus.
This graphics card is not a Max-q either. Its a full 3070RTX card.
A:AnswerThere is a QHD version in similar model but the cost jumps. I prefer the FHD and high refresh rates.
Unless you are building or designing a graphical world FHD is quicker and reliable for gaming/working/streaming needs.
