LG UltraGear 27G64NA

Three hundred hertz at 1440p for $230, where every other panel in this catalog under $250 stops at 180. The panel behind it is an ordinary IPS — LG rates it at 400 nits and 93% of DCI-P3 — so the refresh rate is the whole pitch. The stand is the surprise at this money: height, tilt and pivot, so it goes portrait without an arm. What it has no trace of is a hub, since the one USB port on the back is a service socket and there is no USB-C.

What it does well

300 Hz is the highest refresh rate in this catalog under $400, and it arrives over DisplayPort 1.4 with DSC rather than needing a newer port
Height, tilt and pivot at $230, where a fixed tilt-only stand is the norm
93% DCI-P3 and 8-bit+FRC give it more colour than a 1080p panel at the same price
Two DisplayPorts mean two PCs can stay wired up without an adapter
46 pixels per degree at desk distance — clean text without the GPU cost of 4K

What it gives up

LG's spec sheet and product name both say HDMI 2.1, but the photo caption on LG Canada's own gallery labels the same two ports HDMI 2.0 — so treat the HDMI link rate as unconfirmed until the panel is in front of you
No USB hub and no USB-C — the single USB port is marked service-only
DisplayHDR 400 at 400 nits with no published dimming zones, so HDR is a signal it accepts rather than an image it makes
1000:1 contrast and IPS glow make a dark room the weak spot, as with every panel of this type
No speakers, and the headphone jack is output only

The two lists above come from the maker’s specifications and from published third-party measurements, not from owner reports. Where owner discussion has been read it appears in its own section below, so the two are never mistaken for each other.
