LG UltraGear G6 27G64NA-B: Specs, Features, Pros & Cons
Two DisplayPorts is an unusual thing to find on a monitor this cheap. The 27G64NA-B carries DisplayPort 1.4 twice and HDMI 2.1 twice, which is four full-speed video inputs on a panel sitting at the budget end of the UltraGear line. The single USB-A socket beside them is not a hub (LG's own port legend labels it SERVICE), so there is nothing here for peripherals.
The rest is a speed-first 27-inch 1440p IPS panel: 300 Hz, one millisecond gray-to-gray at the fastest overdrive setting, G-Sync Compatible and FreeSync Premium together. At 109 pixels per inch the density is the standard one for 27-inch QHD, and the panel's job here is refresh rate rather than image quality.
That distinction matters, because LG is careless about it. The marketing copy on LG's own product page claims up to 93% sRGB coverage, while the specification table directly beneath it says DCI-P3 93%. Those are very different claims about a display, and only the second is plausible for a panel of this class. The VESA DisplayHDR 400 badge deserves similar caution: on a 1000:1 IPS with no local dimming it certifies a brightness floor and very little else.
The stand adjusts for height, tilt and pivot but will not swivel, which is an awkward gap next to the other three. There are no speakers, only a headphone jack. None of that is unreasonable at the money being asked. The point is that almost the entire budget went into the panel's refresh rate, and a buyer should want that particular thing more than a good all-round display.

How this VS Score was computed
Score 48: each known spec is measured against the median of IPS gaming monitors, 27 to 31 inches (30 products), then weighted; 50 means level with that median. In classes of six or more, a value beyond the class’s 10th–90th percentile range counts as that limit, so one extreme product cannot set the scale. 70% of the scoreable weight could be used; unknown values, features not applicable to this class and proxies (battery capacity where a rated life exists) add or remove nothing.

Editor’s note
The honest way to describe this monitor is a very fast panel with a display attached, and whether that reads as a compliment depends entirely on what you play. If you spend your evenings in competitive shooters at frame rates that can feed the panel, this is a great deal of refresh rate for very little money, and the input count means a PC and two consoles can stay plugged in permanently.
If you play anything slower, I would spend the money differently. IPS at this contrast gives you the gray blacks it has always given, and the HDR badge does not change that. Dark scenes will look washed out beside any OLED or a decent Mini-LED. LG's own 27GR83Q-B sits close by at 240 Hz with a better-behaved picture, and the drop to its rate is far less noticeable in practice than the difference in contrast.
What I like is the connectivity, which is unusual at this price. Two DisplayPorts is rare, and the second one is useful in a way a third HDMI would not be. What I like less is the stand. Height and pivot without swivel is an odd combination to land on, and pivot on a panel with IPS viewing angles is the adjustment you are least likely to use.
The gamut labeling is the part that would irritate me as a buyer. Being told 93% of one color space when the specification sheet means another is not a small slip, and it makes the rest of the marketing harder to take at face value. Buy this for the refresh rate and the inputs, and treat everything else as adequate rather than good.

The bottom line
The LG UltraGear G6 27G64NA-B earns a VS Score of 48, below the median of the 30 IPS gaming monitors, 27 to 31 inches it is measured against (a score of 50 is level with that median).
- Who it’s for
- Competitive players who already push frame rates high enough to use the whole panel, and who want a PC and a couple of consoles permanently connected without reaching behind the screen.
- Who should look elsewhere
- Anyone who cares about contrast or color accuracy. This is an ordinary-contrast IPS wearing an HDR badge, and single-player games, films and dark rooms will all show it up.
- The trade-off that matters
- Nearly the whole budget went into refresh rate. You get the speed and the inputs, and in exchange you get gray blacks, no speakers, no USB hub and a stand that refuses to swivel.
- The main alternative
- LG UltraGear 27GR83Q-B: a lower refresh rate, but a better-rounded picture for similar money if you play more than shooters.
