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 grey-to-grey at the fastest overdrive setting, G-Sync Compatible and FreeSync Premium together. At 109 pixels per inch the density is the one most people already know from 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 omission on a monitor most people will bolt to one desk position and leave. There are no speakers, only a headphone jack. None of that is unreasonable at the money being asked; the point is simply that almost the entire budget went into the panel's refresh rate, and a buyer should want that particular thing rather than a good all-round display.

Editor’s note
The honest way to describe this monitor is a 300 Hz 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 actually 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 grey 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 genuinely 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 a feature most people use exactly once.
The gamut labelling is the part that would irritate me as a buyer. Being told 93% of one colour space when the specification sheet plainly 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 44, trailing most of the 102 monitors we compare here, at least on the spec sheet.
- 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 colour 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 grey blacks, no speakers, no USB hub and a stand that refuses to swivel.
- The main alternative
- LG UltraGear 27GR83Q-B – 240 Hz rather than 300 Hz, but a better-rounded picture for similar money if you play more than shooters.
