Overall it's a matter of preference a
nd i have it as a draw.
THE MAG251rx has better colors(wide gamut with 8 bit dithering) while the Asus VG279qm has +40hz refresh rate and an ELMB-SYNC that is a good match at higher refresh rates making it faster especially on competitive w/ fast moving objects.
At these ridiciulously high refresh rates, it's really not noticeable whereas the wide gamut and 1 billion colors on top of its oversaturation IS more noticeable. Some people may claim that at 240hz, motion clarity is already good enough as it is. Believe me, if you have the VG279qm at 280hz while ELMB-SYNC is on, if yuo compared it side by side to a 240hz monitor, you will defnitely see a big difference.
Why I chose the mag251rx
1. It's the only TRUE ips panel w/ wide color gamut(although not very much) and 10 bit
2. it's faster at framerates below 180hz than the vg279qm
3. has decent backlight strobing(it's an option that u can use, hpwever it's too dim to use it in my opinion)
4. Has the best g2g response time among all other ips 240hz monitor. (the asus elmb-sync turned OFF and w/o overclocking at 280hz is slower than the MSI)
why i didn't pick the asus vg279qm
1. i don't really play super fast games like FPS titles. I'm a rocket league player
2. i had a dead pixel on my vG279qm monitor and even if i liked it, knowing how picky i was, i had to return it since i cannot tolerate the fact that i spend $400 on something that is defective.
3. the colors are the worst that i've ever seen on an IPS paneel and is dead last among the other 240hz monitors.
4. i didn't like how grainy it looked and that i had to sit way too far away to avoid pixelation
The grainy look and bad uniformity, and low PPI was so bad that i literally had to sit beyond visual acuity distance to mitigate its effects.
for a point of reference, this is how far i had sit to avoid pixelation and the UGLY grainy look at Visual acuity(my 15 yr old 27 inch 720p HDTV had wayy better image quality than the Asus.
if I don't abide by the visual cuity distance of 41 inches, you will see this. The uniformity amplify the backlight bleed and if u sit closer than 41 inches , it's easy to see individual pixels since the bad uniformity amplify it. (especially whites). The closer you sit more blurry it gets.
If you have ANOTHER monitor strictly for content creation, watching movies, web browsing, then PICK the asus tuf VG279qm as a secondary. if you don't, then get the MSI MAG251rx. If you play FPS titles, pick the asus. If you play anything else other than FPS, pick the MSI MAG251rx.
;If you are an esports SPONSORED professional, pick the Asus.
honestly u wont' even notice the differences in performance. I myself hold colors as the #1 criteria into buying an IPS monitor, others for competitive edge. I chose the former because it's redundant having TWO monitors for gaming and for watching movies. it's all a matter of preference.
If it wasnt' for ELMB-SYNC and the +40hz overclock, the MSI would clearly be the better monitor,since i can easily use the lower g2g average argument for MSI. Sadly, the better g2g average argument doesn't apply if ELMB-SYNC is on since MPRT>>>>g2g response time
Buying an IPS monitor NOT for its colors is a MAJOR disrespect to the luxury of owning an IPS monitor. Then again, that's just my opinion.
it's a DRAW
