I have a normal unit, I cannot control the PureXp level.
I use the native resolutions. I don't know how to create a custom resolution with Vertical Total tweak 240Hz scanout.
With CRU.exe if I set the pixel clock to 600Mhz the Hz is also modified to 250Hz.
I added full screen pictures and the pixelclock reported by the monitor OSD.

Good to know my unit isn't faulty or misconfigured.
I guess the technology is still quite limited. I was hoping for no crosstalk at all across the screen.
Do CRT monitors also have crosstalk?
Compared to my 8 year old lightboost TN VG278h monitor I would say the XG270 has
- less crosstalk in 100hz and 119hz (but still similar)
- less blur (spaceship white dots better defined)
- less brightness (waiting for the firmware)
- no buzzing
- easy on/off toggle using configured quick access button
- IPS colors, angles
Made a lot of pictures using full screen Alien Invasion test:

Speed = 1920
Photos using Samsung s10
ISO 500
100, 119, 120 hz - aperture 1/125 F1.5
144 hz - aperture 1/180 F1.5
240 hz - aperture 1/250 F1.5
Ignore the black bands in landscape photos and vertical black bands in portrait ones, that's a mismatch between my phone camera aperture and the monitor refresh rate.
Photos look very similar to actual perception.
Included pictures of full screen, left, middle and right screen:
- 100, 119, 120, 144, 241 hz (overclocking activated)
- 100, 119, 120, 144, 240 hz (overclocking deactivated)
Summary of the photos:
100hz - 114.6Khz/99.9hz 302.6 Mhz
> upper to middle 50% = very low crosstalk
> very top = colored pre ghost
> lower part = colored after ghost

119hz - 134.9Khz/119.9hz 296.7 Mhz
> upper to middle 40% = very low crosstalk
> very top = overdrive after ghost + colored pre ghost
> lower part = colored after ghost

120hz - 135.1Khz/120.1hz 297.0 Mhz
> middle to lower 20% = very low crosstalk
> very top = overdrive after ghost + colored pre ghost

100hz and 119hz are the best modes.
I would not use the other ones.
Can't tell if the Overclocking option in the monitor OSD affects crosstalk.
