Monitor's timings effects visual fluidity , need opinions

Ask about motion blur reduction in gaming monitors. Includes ULMB (Ultra Low Motion Blur), NVIDIA LightBoost, ASUS ELMB, BenQ/Zowie DyAc, Turbo240, ToastyX Strobelight, etc.

Monitor's timings effects visual fluidity , need opinions

Post by amorou » 21 Jan 2023, 13:15

Hi , ever since i got my monitor (Aoc 24g2u) , it felt like smth about it not right, even my 15 year old LG monitor that pushed to 74hz was better than this.

So when i use CVT-RB timings from CRU , games visuals appear more pleasing to the eye , not just when moving and stuff , even while stopping and looking at same frames.

Than started researching stuff , I ve read about increased blanking can reduce motion blur. (Yet also a fixed image looks better tho)

But here is my problem , when I use any other timing , mouse movement becomes really bad , but not just a added lag , its less consistent.

The diffrence is pretty obvious , I can pick it in blind test 10000 out of 10000 times.


So why this is happening? What can I do to have nice visuals and consistent mouse movement.
Maybe increased pixel clock emit more electromagnetic stuff and some circut on monitor cant keep up? idk


Not sure if this is the proper board to post it.

Do you use Overdrive boost or MBR 20? From my settings here /viewtopic.php?f=4&t=11677 it's better than 144hz. Do you use 1000hz mouse?

Probably try to use CVT-RB timing / Default, but only change the Vertical Total (120hz stopped at 1405, 144hz stopped at 1171)

Are you familiar with the Frameskipping Test?
https://www.testufo.com/frameskipping

Timings can affect frameskipping due to firmware bugs, etc.
See viewtopic.php?t=3598
That's a very old thread. Look at the data of that thread.

However, motion blur from increased jitter, is a separate problem from reduced motion blur from better strobing. They're not the same thing:

Unrelated different cause of motion blur (aka strobe crosstalk).

Your problem is frameskipping, not motion blur.

(Although high-frequency frameskipping can jitter so fast, that it looks like extra motion blur -- ala stutter-to-blur continuum, see demo www.testufo.com/eyetracking#speed=-1 where stutter is the same thing as persistence motion blur, where stutter is akin to a slow-vibrating music string and blur is akin to a fast-vibrating music string that vibrates so fast it's blurry.)

But don't confuse these two (frameskipping problem versus strobe crosstalk problem).

That's as erroneous as 2+2=5 because your monitor has a known frameskipping bug. So that's just conspiracy or flat-earther stuff. Stay with science please, as we are a science-based discussion forum.

Frameskipping is caused by monitor firmware not being able to keep up with specific signal timings, or via other bugs. Some early monitors shipped with firmware bugs that created frameskipping for years, and your monitor is one of those models! Known Bug, Known Issue, Not Opinion, Not Electricity, Not EMI.

Motion blur can come from many causes (GtG or MPRT).

I have moved this thread to the correct forum (Display Overclocking).

I've even been paid by a monitor manufacturer to fix frameskipping problem.

Is that just frameskipping , or smth more ?
