MSI OPTIX MAG251RX Review by RLCSContender

[Chief Blur Buster]

Ok, but for me, I don't know what any of the terms, lingo, numbers, etc.. mean. (other than input lag and hz/fps/refresh rate)..

For GtG and MPRT, see Pixel Response FAQ: GtG versus MPRT

Excuse my Ignorance, could you please tell me what are the G2G/MPRT of the MAG251RX and the VG279QM?

(One last thing) Does the G2G/MPRT change if your OD setting is higher or ELMB-Sync is turned on? Appreciate the Info! Thank you

GtG can sometimes be difficult to measure -- since it varies with so many factors. However, GtG ideally should be a fraction of a refresh cycle to prevent interfering with the motion clarity of high refresh rates.

MPRT of non-strobed usually resembles a full refresh cycle.
MPRT of strobed usually is ~1ms, and sometimes adjustable (pulse width exist for ULMB, DyAc, PureXP+).

GtG is pixel transition time = more co-related to LCD motion artifacts
MPRT is pixel visibility time = more co-related to display motion blur

Overdrive settings changes GtG but often with side effects. You aim for goldilocks setting (not too fast, not too slow)

Enabling strobing (or raising refresh rate) lowers MPRT. Strobe pulse width adjustments lower MPRT even further. Slow GtG overlapping multiple refresh cycles is bad for strobe crosstalk. Also, strobe crosstalk can occur from strobe algorithmic decisions (e.g. low frame rates in ELMB-SYNC sacrifices crosstalk quality in order to prevent visible flicker).

@RLCSontender Nice comparisons

I +1 that, RLCScontender guy is what made me join this forum ! I really appreciate the time you spent and also your blunt character. Sadly in this thread no one is answering my questions, so maybe I'll try another thread ? Or start yet another one of them overused "what should I buy for my particular tastes/needs" threads haha !. I was just trying to save forum space and/or redundant topics. lol

Anyway, all jokes aside, all praises due to RLCScontender !! Unbelievable research, dedication and technique !

Thanks

I like to keep my posts in the best interest of the consumer. i just tell the truth, and i try to limit opinions and subjective as much as possible. There's a guy in this thread literally arguing the 10 bit signal as if it doesnt' matter. Yet, i did my homework and i saw noticeable banding and bad color uniformity when i lowered it to 8 bit, but he insists that "i'm rong".



A lot of people who disagree with me are usually the owners of that monitor or has a strong preference for it so they need to try to defend it. I get it, they've spent hundreds of dollars on it.


Could u link me to that topic? i will answer it.

Yea, I call that "defending your purchase". In my field (music industry), that happens too. Either that, or them unbearable "fanboys" haha

Well thanks man, but I haven't made that dedicated thread yet. I guess I will now. As I do not want to sidetrack this thread and the geek talk here really does have my head spinning. lol I don't need numbers, phrases, the lingo, etc.. that makes me lost as I don't understand it. I just want a answer that has a brand name and model number in it, ha !

In hardware unboxed review they say that on a Faster OD preset MAG monitor performs well for 240hz however at 144hz there will be too much overshoot. What if you run it at 240hz (freesync off) and get 80-150fps in game will the overshoot problem still persist?

yeah, i' m aware they said that and i tested it myself and i saw little to no over shoot(just in early transitions, which it will give a slight blue glow). However, the overshoot is slightly more aggressive at 144hz than at 240hz or 60hZ. So if that slight blue glow bothers you at 144hz, just lower the overdrive from "faster" to "fast", where u get no overshoot. (although a dip in g2g from 3ms to 5ms(4.5ish)

Lowering the overdrive from "faster" to "fast", fast will introduce zero overshoot at 144hz, but there's a big dip in G2g average from 3ms to 4.5ms. Then again, 4.5ms is literally equivalent to the LG 27gl850, which is the 2nd fastest 1440p IPS monitior(only the 38" LG ultrawide is faster than the 27gl850)

also,i don't like how they compared the msi mag251rx to the LG 27gn750. They used its "fast" overdrive setting to compare to it instead of "faster". and concluded that "see? the 27gn750 is superior in every way". That video was laughable at best because that totally contradicts their statement on their MSi review that at 240hz, the optimal overdrive is "faster" yet they used "fast" to compare it to the 27gn750.

btw, "fast" at 240hz refresh for the MSI is much too slow to comply with 240hz refresh. "faster" is the only overdrive setting that is useable if the monitor is at 240hz refresh.

again, keep an open mind when you see these reviews. They are not always exactly on the consumer's best interest. Financial incentive is problematic among mainstream review communities.

Sorry I still don't quite get it... is the overshoot issue on Faster setting tied only to the Hz rate of the monitor or in-game frame rate aswell?

Example: 240hz, Faster OD, freesync off, ingame fps around 140. Will these results(overshoot) be the same as when the monitor is running at 144hz?

With VRR (FreeSync and G-SYNC) enabled, frame rate is refresh rate, and refresh rate is frame rate. It's the same thing, no difference, within VRR range (e.g. 48Hz-144Hz means 48fps-144fps always have perfect fps=Hz sync).

So yes, game frame rate can affect overshoot visibility during VRR.

Example: 240hz, Faster OD, freesync off, ingame fps around 140. Will these results(overshoot) be the same as when the monitor is running at 144hz?

If FreeSync is OFF then your overshoot issue will be a fixed-amount regardless of frame rate... the overshoot usually happens for one fixed-Hz refresh cycle, regardless of frame rate and sync technology. Ultimately, how that looks to your eyes (varying or non varying) semi-depends on how your brain converts a series of static images into a continuous moving images. Some people see ghosting/corona artifacts more immediately even at low frame rates (30fps at 144Hz), and others really don't notice it nearly as much as at high frame artes.

Thank you, this what I wanted to know.
