Low MPRT is easy by pulse width adjustment -- NVIDIA ULMB Monitors have achieved as low as 0.25ms MPRT or thereabouts.purplew wrote: ↑08 Sep 2020, 16:31Does anyone own one of these? They're newly released and use propriety tech to achieve 0.4ms MPRT..

So, basically "0.4 ms response time" is just a marketing slogan, and it only applies to strobing?Chief Blur Buster wrote: ↑08 Sep 2020, 16:55Low MPRT is easy by pulse width adjustment -- NVIDIA ULMB Monitors have achieved as low as 0.25ms MPRT or thereabouts.purplew wrote: ↑08 Sep 2020, 16:31Does anyone own one of these?

The biggest problem is cramming maximum lumen per microsecond to get the low-MPRT as bright as possible, through careful voltage-boosting of a strobe backlight mode. (LEDs can be overdriven about 2x-5x current when briefly pulsed)
Thanks for the reply, but as @speancer asks, does this mean it wouldn't perform better than current 240hz IPS monitors just on the 0.4ms number alone?Chief Blur Buster wrote: ↑08 Sep 2020, 16:55Low MPRT is easy by pulse width adjustment -- NVIDIA ULMB Monitors have achieved as low as 0.25ms MPRT or thereabouts.purplew wrote: ↑08 Sep 2020, 16:31Does anyone own one of these?

When it's tested and if it's better than the others then it will, be if not then it won't. As you can see 1ms 240hz response times can vary a lot with current monitors. Some are better than others.purplew wrote: ↑08 Sep 2020, 17:15Thanks for the reply, but as @speancer asks, does this mean it wouldn't perform better than current 240hz IPS monitors just on the 0.4ms number alone?Chief Blur Buster wrote: ↑08 Sep 2020, 16:55Low MPRT is easy by pulse width adjustment -- NVIDIA ULMB Monitors have achieved as low as 0.25ms MPRT or thereabouts.purplew wrote: ↑08 Sep 2020, 16:31Does anyone own one of these?

I get it now. So it's just marketing of their ULMB method. ThanksChief Blur Buster wrote: ↑08 Sep 2020, 17:39Correct.
MPRT less than refreshtime requires the use of a strobe backlight.
See Pixel Response FAQ: GtG versus MPRT
It explains how GtG and MPRT numbers are calculated.
GtG is pixel transition time, more responsible for ghosting/corona effects but can add extra blur when slow.
MPRT is pixel visibility time, directly proportional to visible display motion blur.
The only way to get low MPRT without strobing (1ms MPRT) is 1000fps at 1000Hz. See Blur Busters Law: The Amazing Journey To Future 1000Hz Displays.
