There has been a lot of 240hz 1080p IPS monitors as of late. From the first generation (xg270, acer nitro X52 panels, and AW2718

MSI MAG251rx, LG ultragear 27gn750, and VG279qm/VG259qm.

I'm curious about the LG Ultragear 27gn750. It's available for puchase for $399.99. it's 99% SRGB; however, it's 240hz. There's basically zero information about it except it has 240hz, uses the same panel as the LG(but no wide gamut backlight). It is however the best looking 240hz monitor that i saw. The problem is that it will have low PPI since it's only 1080p at 27 inches. however, if you sit far enough, it won't really matter and because it's 240hz, the performance and motion clarity will definitely be better than its 144hz LG counterparts.

VG259qm from what i'm seeing will be 6 bit+FRC (so it will have a lower gamut than the VG279qm) counterpart. However, the pixel per pinch will be higher at 89 for the VG259gm compared to 81 from the VG279qm. I donn't know if they will lower the gamut on the VG259qm but that would suck if they did.

MSI MAG251rx from what i hear has the overall fastest response times for an IPS 240hz panel, but i don't know if anyone can confirm this. Hardware unboxed clock its G2G at 3.2ms whereas. TFTcentral clocked the average g2g for the VG279qm at 3.6ms then again, both sources probably use different standards.

Lastly the AW2521HF/AW2721HF was recently released. Not much information about their G2G at all

ALL of the aforementioend IPS panels claim 1ms on their ad but because there aren't much reviews on these new IPS 240hz monitor, it's really tough to know which is the fastest.

Just returned the MSI MAG251rx just now. It's a wide gamut monitor with no sRGB which is a major dealbreaker. i measured at 111% sRGB. The stand is pretty bad and clunky. If your monitor falls down, it will crack easily. not to mention the overly tacky gamer aesthetics and "esports"

The only redeeming factor is the response time and ridiculously low input lag This is by far the fastest IPS monitor i've ever tested. (it's way faster than my viewsonic xg270qg even with its variable overdrive). I used two sources to measure response time(Eizo and this website). Average g2g was a whopping 3.1ms(that is better than most high end TN monitors). This was measured at 80 overdrive at its 240hz refresh rate. Even on lower refresh rates, the g2g average never goes above 4ms. That means this is good for console gaming.

The backlight strobing is actually above average(yes, you can strobe at 240hz). I tried it and i didn't see much difference, except the screen got dimmer. I dont' see the point of using backlight strobing if your FPS is running above 200 on this monitor because it's already buttery smooth without it. i Truly belileve this is the fastest 240hz IPS monitor right now. Gaming aside, everything else is atrocious

Poor/clunky stand and bad ergonomics.
No sRGB mode to clamp the oversaturation. Everything will be washed out
HDR is crap, dont' even turn it on. It has about 1100:1 contrast ratio, but there will be a lot of input lag.
Monitor aesthetics is not visually pleasing whatsoever(especially with its tacky esports logo and color)

in terms of perfomance, this monitor delivers. However, i'm willing to trade a slightly less response time for srgb mode, better stand, etc because at this low of a response time, it's really imperceptible (especially among other 240hz monitors).

I don't recommend this monitor even as a side monitor for gaming because everything else outside of gaming is pretty bad. There are other monitors(it will probably be slower than the msi mag251rx but with better aesthetics, has sRGB mode, and better ergonomics, etc) because a slightly faster response time from 3.1 to 3.6 is negligible). . In general though, if i was NOT comparing this monitor relative to other high end 240hz monitors, this is a phenomenal. Then again, the 240hz 1080p market for IPS panels is starting to get competitive(and perhaps oversaturated).

Next up is the VG279qm. I purchased it through amazon and it's coming in a couple of days. Can't wait to try it out

I'm finishing up my review of the VG279QM right now, and here's a quick spoiler: the response times are fantastic. I like everything about this monitor except for the strobing modes and ELMB-Sync, which are huge messes. If strobing doesn't matter to you, I think you'll be impressed when you get yours in.

Where do you get that the VG259qm have lower corlor gamut than the 27" version?
I Just ordered the 25" and I've missed this, did i fuck up?

https://www.tftcentral.co.uk/blog/asus- ... elmb-sync/
here it says the 27" and the 25" are indentical?

according to this link, the 25 inch version is 6 bit, whereas the 27 inch version is 8 bit. 6 bit+frc is still 6 bit.

Also, vg279qm is 118% SRGB whereas the 25 inch version is 99% srgb

Lastly, VG279qm has a display minimum response time of 1 ms but the 25 inch version has a 4 ms display minimum response time.

https://www.displaydb.com/compare/asus- ... ng-vg259qm

This site also says 6 bit colors for the 25 inch version, whereas the 27 inch version is 8 bit. Howver, they both have them as 99% SRGB. Both have a 4ms display minimumk response time.

overall, it looks like the 27 inch version will have a wider gamut than the 25 inch version. The only added benefit to the 25 inch version is 89 ppi vs 81 ppi for the 27 inch. Then again, i always sit at least 3 feet when i play videogames anyway (especially console games) so it's a matter of preference. I never lean in when i game, i always sit back

One thiing i can 100% confirm.

vg259qm has a lower gamut. It runs on 72% NTSC
VG279qm is wide gamut with 99% srgb+++ and DCI-P3 95%

keep in mind, 72% NTSC vs 99% SRGB is basically the same thing, just different criterias. However, vg279qm is 95% DCI-P3 , whereas the VG259qm is on standard sRGB.

You can look up their specs on the website. Basically the 27 inch version has a wider color gamut(with emulation SRGB) whereas the 25 inch version is the sRGB version of the monitor. However, the advantages of the 25 inch version is higher PPI which means sharper screen. Then again, that's only if you sit about 3.2 inches or MORE. In the 27 inch version, the visual acuity is 3.4 inches or more. Basically you can siot a good 3-4 inches closer to the 25 inch version vs the 27 inch version.

I'm guessing the 25 inch version will be $100 cheaper when it gets released. The only major difference is the color gamut. When it comes to gaming, they are the same.

I already bought that ASUS VG259qm, for sure version of 24 inch is better for 1080p based on pixel scaling, no matter how far you lean or sit.

+also if you check the tests:
https://www.tftcentral.co.uk/reviews/as ... g279qm.htm

Version of 27 inch doesnt also have 1 ms response time, well, yea, it does but only with max override + you have a lot of overshoot due of that. It has 3.6 response time with 240 hz (most stable, 280 iz marketing) + override 80.
That is why maybe they put 4ms on that VG259qm, because its actually real truth

And yes, this monitor has fastest response time and very low input lag based on tftcentral, so its actually very nice monitor, actually its fastest than mine TN only downside is a motion blur, but if It deliver to me I will test that

As I heard this 24 inch asus has the same panel as 27 inch, I dont know why it says it has lower gamma colors. I would not worry about that, 24 inch for sure will looks better on 1080p instead of 27 inch, even if it has better gamma colors, but why It would be worse compare to 27 inch?

The visual acuity for the 24.5 inch version is 3.2 feet. The visual acuity for the 27 inch version is 3.4 feet.

Basically, if you sit closer than 3.2 feet, you will start to notice pixels. The same goes with the 27 inch version at 3.4 feet. So yes, the 89 ppi for the vg259qm is higher than 81 ppi for the vg279qm but the viewing distance is negligible(2.3 inches or 6 cm) when it comes to sharpness.

Visual acuity (optimal viewing distance for a person with 20/20 vision)

VG259qm=38.4 inches or 97.5cm
VG279qm=40.8 inches or 103.5 cm

So yes, you can sit a good 2-3 inches closer to the monitor without noticing any pixelation on the vg259qm.

Here's my 2 cents on this. If you are a competitive gamer, the 25 inch version would benefit a lot of people because there's less eye tracking and you can sit 2-3 inches closer due to better ppi. However, if you are a casual gaming, the 27 inches is simply better(better immersion, wider gamut, etc). I also intend to use the vg279qm for the ps5/xbox series x and in my opinion, console gaming is better and more immersive with larger panels.

Lastly, about the gamut differences.

Here's proof

https://www.asus.com/Monitors/TUF-GAMING-VG279QM/

VG279qm is wide gamut, 95% DCI p3 99%SRGB

https://www.asus.com/Monitors/TUF-GAMING-VG259QM/

VG259qm is 72% NTSC (the same thing as 99% SRGB) but there's no 95% DCI-p3 indication on their website.

The visual acuity for the 24.5 inch version is 3.2 feet. The visual acuity for the 27 inch version is 3.4 feet.

Good generla guidelines.

That said, that's not the final frontier. Visual acuity varies a lot with many variables, such as amplified aliasing effects -- see TestUFO Aliasing Visibility Test. I see a resolution limitation of 24" monitors from more than 15 feet away with this test!

This amplifies resolution limitations, requiring more distance to solve. That's why we have to use good gamma-corrected anti-aliasing algorithms on perfectly colorimeter-calibrated monitors, in order to have perfect bead-free slightly-diagonal lines at the lowest possible resolution. (And we haven't talked about adding a little overkill resolution as an oversampling manoever to fix nyquist issues of things like fine grates and grids yet). Big rabbit hole to fall in.

Not important information for most users though, just some additional "Blur Busters Flavour" technical information that surprises many, like our 1000 Hz articles or sub-1ms-visible demos, etc.

TFTcentral only reviewed the 27 inch version, he never reviewed the 24.5 inch version.

Here's a link to the chinese review(with the factory settings) of the VG279qm
