Gigabyte Aorus FI25F (0.4ms MPRT 240hz IPS monitor)

Post by purplew » 08 Sep 2020, 16:31

Does anyone own one of these? They're newly released and use propriety tech to achieve 0.4ms MPRT..

Low MPRT is easy by pulse width adjustment -- NVIDIA ULMB Monitors have achieved as low as 0.25ms MPRT or thereabouts.

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)

So, basically "0.4 ms response time" is just a marketing slogan, and it only applies to strobing?

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?

1ms is also marketing slogan as I've never seen a monitor hit 1ms average

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.

Correct.

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.

I get it now. So it's just marketing of their ULMB method. Thanks

that 100% srgb and 24.5" is intriguing and i will definitely buy this. If 100% srgb checks out and the pixel response time doesn't overshoot on its optimal overdrive setting, this would be a keeper for me.

Gigabyte also has one of the best OSDs on the market. Will be interesting to see how this one stacks up against VG259QM and MAG251RX etc.

This monitor has now been out for a couple of months, but still no reviews in sight. Did anyone try this monitor?
