The LG 34UC79G-B is a special monitor for more than one reason. For starters it is the first gaming monitor of the brand in a long time, with a fitting design. Secondly this is the first 144 Hz IPS 21:9 monitor with a panel that is manufactured by LG Display. Last but not least LG equipped this model with an anti-motion blur function, in the form of a blinking (strobing/scanning) backlight. Furthermore all of this comes at a pretty modest price, with an average price of 535 pounds / 599 euros the LG 34UC79G is certainly not too expensive.
We have to add that while the monitor does have FreeSync support, it is with a relatively limited range of 60 - 144 Hz. The curve of the panel is also slightly less than the Acer, Benq and AOC models. In terms of connectivity we find two times hdmi 2.0 and a single displayport, plus a usb 3.0 hub. The monitor does not have built-in speakers, but we do not think this is that big of an issue.
With the test results it stands out that IPS-panels are not as fast and have a slightly higher overshoot in order to achieve the necessary speeds. Out of the three LG models this one does have the best response times, but the difference is marginal. Furthermore the 6.94 ms that is necessary for 144 Hz is not reached, especially in black-white and white-black transitions - albeit barely. The result is some motion blur; dialing back to 120 Hz is an adequate solution to this. Of course this would not have looked as good on the box.
Looking at the other test results, an excellent uniformity of white stands out while the black is below average. The minimum brightness of white is rather bright as well. The vertical viewing angels are reasonable, but not fantastic - especially not when compared with the VA-competitors. The colour space is slightly smaller, although it is not bad. This is basically the case for all of the results of the colour quality: it is solid, but somewhat lacking when compared with the rest of the tested models, whether we look at colour fault, the contrast, the black value, etc. Only the gamma value and grayscale deviation are clearly better than the others, but that is not enough to recommend this monitor without a doubt at its current price. If LG would offer it for 89 pounds / 100 euros less, it would be an excellent affordable option, but the price difference with the competitors that are clearly better is simply too small now.
