Response time types

[Half Life]

Hi guys,
Searching for a new monitor I read on some reviews the MPRT y VRB response times. I want to know if all VA and IPS panels can't not works with A-Sync and MPRT/VRB response times. I mean, if you have ON the A-Sync you lost the 1ms MPRT/VRB response time and you have rt>1ms response time?
The TN panels with 1ms GtG have this effect if the A-Sycn it's ON?

Thanks for the help!

MPRT = moving picture response time.

Its another measurement of pixel transition speed. and just like GtG (grey to grey), the figures from the manufacturer should be mostly ignored.

 

Real world response times, as tested by reviewers like rtings , tftcentral ,and pcmonitors.info, are always different from what is advertised, as whats advertised is a very specific result from a very specific test method which is not representative of the average response time in real world use cases. In addition, you could get 10 different monitors all with an advertised MPRT or GtG response time of 1ms, and they will all in fact be completely different when tested in real world usage.

 

No Monitor as of this moment can achieve an average response time, using 'usable' overdrive settings, of 1ms, even the most expensive TN gaming panels.

 

Now as for Adaptive sync and not being able to hit certain response time figures. Its not that u cant hit them, its that in most cases when using overdrive, and sometimes even when not, and Adaptive sync at the same time, when the frequency of the display drops to match a lower FPS, the Pixel response also slows down, this is due to the way the panel is being driven and how overdrive can be implemented by the hardware inside the display.

Another issue with adaptive sync being active is that many displays if they have BFI (black frame insertion) available to make the motion of an image clearer, this becomes disabled if u turn on Adaptive Sync as u cant have both adaptive sync and BFI on at the same time.

 

What has been said above is the same for all LCD type displays, be them TN, VA, or IPS panels.

 

Hope this answers ur question.

Actually, yes. You explained the cases very cleary.

 

In case with 144Hz monitors, A-Sync OFF for eSports games and A-Sync ON for other type of games. What do you think about that?

If the display had BFI which only worked with A-Sync OFF, then YES A-Sync off, BFI on for Esports.

 

If however the displays has no BFI or it does and can be on with WITH A-Sync, then use A-Sync with Esports.

I get it!

 

One last thing, the BFI it's the technology named Flicker Free or Motion blur?

Woops wrong thread - im sorry for this qoute

BFI can have different names depending on the manufacturer. Such as ULMB, LightBoost, etc,etc. Can even be called something like 'Aim Stabilizer' as is the case with Gigabyte Aorus AD27QD

 

Flicker free is in reference to the backlight control style. Be it PWM or Static DC.

 

PWM can still be flicker free as it can 'flicker' at such a high frequency that u cant see it. Its not a setting per say, its more so how the display is designed. While lowering brightness in some cases with PWM backlights can introduce flicker (to lower brightness this way requires a slower PWM frequency, thus slowing the flicker frequency, resulting in a situation where u could potentially notice flicker), its not always the case. Reviewers will mention this if it is the case.

 

The best BFI solutions are matched up with PWM backlight control and synchronized to reduce crosstalk.
