What published reviews found

PC Gamer was positive about image quality. It described the colors as well calibrated and vibrant, praised the sharpness at 27 inches, and said response times approached what you would expect from an OLED. It also liked the anti-glare coating. The criticisms were limited HDR, since the panel is HDR400 without local dimming, a build that felt inexpensive for the money, the missing USB-C port and a price that made it harder to justify against alternatives.

MonitorNerds recommended it for 4K 144Hz gaming on PC and consoles. It reported a default color error of 2.76 delta E that dropped to 0.91 after calibration, a peak brightness of 389 cd/m² (414 in HDR mode), 1,145:1 measured contrast and 4ms of input lag at 144Hz. It called contrast and HDR performance limited, noted there are no built-in speakers, and mentioned the stand is 10 inches deep.

Both outlets pointed to the same trade-off. You get 4K sharpness and fast response on an IPS panel, but contrast and HDR trail OLED and mini-LED displays.

Price and availability

PC Gamer listed the monitor at $630 in its review. Adorama's listing for the LG 27GR93U-B states that the item is no longer available for purchase there, so stock may be limited and prices can differ widely between sellers. Check current prices on our monitor deals page before buying, and do not assume the PC Gamer figure still applies.

Who it's for

This monitor suits players who want 4K sharpness at a high refresh rate on PC and also want a console connection, since both HDMI ports are 2.1. It is a good match if accurate IPS color matters more to you than OLED contrast and you want to avoid burn-in worries.

Skip it if HDR gaming or movies are a priority, if you want USB-C for a laptop, or if you need a stand that swivels. For much better contrast and HDR, an OLED such as the Alienware AW3423DWF is the usual step up, though it is an ultrawide at 1440p with different trade-offs. If you would rather save money and stay at 1440p, consider the ASUS TUF Gaming VG27AQ. A 4K panel also needs a powerful GPU to hit high frame rates.

Bottom line

Published reviews agree that the 27GR93U delivers sharp, accurate, fast 4K on an IPS panel and works for both PC and console. HDR is weak, contrast is ordinary, and the price drew criticism. It makes sense if you find it at a fair price and value pixel density over contrast.
