- No 240Hz panels can strobe perfectly clear top-to-bottom for the entire screen for 240Hz.
- This is why some vendors lock their strobe range to not run at high strobe Hz at 240Hz (e.g. ULMB 144Hz max)
- However, with XG270 you have a choice. You can strobe at any Hz (in 0.001Hz increments) from 75Hz through 240Hz.
- You can choose how much strobe crosstalk you are willing to tolerate.
Here's a motion blur chart:
PureXP = OFF
PureXP = ON
The four PureXP+ levels is calibrated to between 10% to 40% refresh cycle (in 10% increments) so your MPRT(100%) will vary from as little as <0.5ms MPRT (screen middle, 240Hz PureXP Ultra, but lots of crosstalk) to >5ms MPRT (screen middle, 75Hz PureXP+ Light).
In other words, for 1ms MPRT(100%) without using a motion blur reduction mode (strobe backlight mode), you need 1000fps on a 1000Hz display to match in a non-strobed manner.
