68ppd · retina-classAccepts an HDR signal~$500
Two HDMI 2.1 inputs are what separates this one from the rest of LG's 27-inch 4K line, and they are the reason it keeps turning up in console threads: a PS5 or a Series X drives it at 4K120 without compression or a fallback mode.
Best for: One desk shared by a PC and a current console, without a bandwidth compromise on either

LG UltraGear 27GR93U: what it gives up
- DisplayHDR 400 with an edge-lit backlight and no dimming zones — the HDR mode makes the picture dimmer and flatter, not better
- 1000:1 static contrast means blacks are grey in a dark room, which is the whole reason people cross-shop this against an OLED
- IPS glow in the corners on dark content is the usual lottery and LG does not screen for it
- No USB-C, so a laptop needs a separate dock
- Speakers are absent entirely; the headphone jack is the only audio path
LG UltraGear 27G64NA: 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
