Unless you have a variable-persistence strobed TN that stays bright at 0.25ms MPRT.
1. Get a bright
adjustable persistence strobe backlight. Such as 240Hz GSYNC(w/ULMB) or 240Hz DyAc
2. Use
huge headroom "Hertz-below" strobed Hz for lower strobe crosstalk (e.g. 100Hz or 120Hz strobed on a 240Hz panel)*
3. Slightly
bump the digital black level upwards slightly (in NVIDIA Control) to reduce ghosting crosstalk
4. Now you've got near zero strobe crosstalk (Above Average, near undetectable, in
Strobe Crosstalk FAQ)
5. Adjust
strobe width (either
ULMB Pulse Width or
BenQ Strobe Duty) downwards to one-quarter original setting.
6. Now I can perfectly read the street names on
TestUFO Panning Map Test at 3000 to 4000 pixels/sec on my TN!
You cannot do that with normal ULMB / ELMB / DyAc at default settings.
And it beats CRT in motion clarity.
Well. Some of them. At least the
Sony FW900 CRT. Try that panning map readability test on a Sony FW900 CRT (medium-persistence phoshpor), it begins to fail at slower motionspeeds than the best variable-persistence strobe-backlight TNs.
Yes,
the CRT has better colors, better blacks, but the TN motion clarity beats CRT if instructions are followed correctly when you have a fine-tuned variable-persistence strobe backlight. Reducing a 1ms MPRT 300nits will reduce nits to 75nits during 0.25ms MPRT, so you do lose a lot of brightness, so it's a brightness tradeoff, and that's why you need one of the brighter strobe backlights. I've even gotten as low as 0.1ms MPRT (but too dark picture)...
*Note: If using non-ULMB, use the Large Vertical Total tricks too, see Appendix A of Crosstalk FAQ
Adjustable persistence dates back to the
LightBoost 10% trick days. The strobe width follows
Blur Busters Law darn near exactly (1ms strobewidth = 1ms of motion blur per 1000 pixels/sec). Which means 0.25ms flash only generates 1 pixel of motion blurring at 4000 pixels/second motion.
