Uncalibrated – Maximum Backlight Level
The MAG321CURV is somewhat unique in its feature set, so comparisons are a challenge. In price, the Asus TUF Gaming VG289Q comes closest with its 4K resolution and HDR support. Other screens in the 30-35-inch range are the Dell SG3220DGF, BenQ EW3280U, Viotek GNV34DBE and AOC CU34G2X. All of the monitors in the comparison group are VA, except for the BenQ, which uses an IPS panel.
None of the monitors here are particularly bright in SDR mode. Still, 300 nits brightness is enough for any indoor environment, though users would be wise to avoid the sunniest windows. The MAG321CURV delivered decent black levels with a third-place finish, and its static contrast is good enough for a second-place score of 2,607.3:1. It’s the best of the rest after the Dell, which is well ahead of the sample group at over 3,780:1. Obviously, the IPS panels, though good for their category, lag behind the VA displays in our contrast test.
After Calibration to 200 nits
Calibration (see our recommended setting) costs the MAG321CURV a little contrast (2,607:1 versus 2,120:1), but the improvement in grayscale accuracy is worth the sacrifice. Black levels were still low at just 0.0954 nit. Our sample showed some slight uniformity issues, which cost it in the ANSI test. Yes, 1689.9:1 is still a respectable score, but the Dell and Viotek screens kept their intra-image contrast closer to 3,000:1.

Yep! Any monitor or even TV for that matter that doesn't have adaptive sync isn't worth the purchase in 2020 unless you positively won't game on it.
I owned the Samsung UR590C which is the same panel this monitor is based on. The MSI monitor is cheaper, the stand is ridiculously better, port selection is better, and USB-C at least brings another DisplayPort input (to get 10-bit color). A back panel that has relatively unobtrusive light feature and is attractive is also a win over the UR590C which looks and feels cheap. You also get VESA mount compatibility with this display.
I will say the lack of adaptive sync hurts. I expected it considering there are still marketing sites that list it as a feature for this panel (and was hinted at computex 2019 I think). Obviously I was hoping a firmware update might bring it, but I think it was just mis-marketed or the firmware wasn't ready at ship time. I had hope, as Samsung has brought freesync to other monitors, but the UR590C never got it, so I doubt this monitor ever will. I didn't get it for HDR (as it really does suck on this monitor - just a checkbox feature).
There are still quite a few (although it's getting smaller) games out there locked at 16:9 and 60Hz where this monitor shines. Dark Souls, and StarCraft2 are 2 games I play frequently that are locked with these limitations - so this monitor is great for those - especially since framerate isn't a problem, even at 4k. The curve makes for a sublime experience - and I'm happy with my purchase (after selling the UR590C and grabbing this at $350).
I would say the Phillips posted by @burniemac seems to be the real winner here, as it obviously is the same panel (I don't think anyone but Samsung is churning out 1500R 4K 32" panels) with adaptive sync, speakers, and lacks only the USB-C input and arguably useless hub. It's just a shame that MSI couldn't get adaptive sync in their variant, as it would make it better in my opinion if only for the port selection and excellent stand.
If you're considering a 32" 4k curved monitor and you're locked (either due to console or game support) to 16:9, get one of these around $350 - you won't regret it. 4k at 32" is usable in Windows at 100% scaling - which is awesome. Otherwise, 27" 144hz adaptive sync monitors are better for your general gamer IMHO. Just be careful, I have a 27" 144hz, and hard to use despite being a better 'all around' monitor after getting used to the 32". Bigger is better in general use.
