LG 27GS93QE 27" Ultragear OLED Gaming Monitor (240Hz, 0.03ms) Review

TL;DR

LG's 27GS93QE 27-inch Ultragear OLED Gaming Monitor at QHD 1440p 240Hz is the right gaming display for serious PC and console gamers. OLED panel delivers per-pixel control for absolute black levels (0 nit), 240Hz refresh rate matches the highest competitive gaming standards, and 0.03ms response time eliminates motion blur. DisplayHDR True (genuine HDR, not fake-HDR) plus the OLED self-emissive panel produces the best HDR gaming experience available outside of premium TVs. At its price point, it's competitive with Samsung's QD-OLED and ASUS PG279QM tier.

Why It Matters

Gaming monitors split between IPS LCD (good colors, slow response, gray-black levels) and OLED (perfect blacks, instant response, but burn-in concerns). For competitive gaming, OLED's 0.03ms response time is the difference between reaction and pre-action — opponents disappear from your peripheral vision before you've registered them. For HDR-supporting games (most modern AAA titles), OLED's per-pixel contrast makes nighttime levels actually visible while bright HDR effects pop.

Cons

• OLED burn-in risk with extended same-image use (HUDs, taskbars)

• LG's image-retention compensation can show transient artifacts during cleaning cycles

Who It's For

Serious PC and console gamers. Competitive shooter players (response time matters). HDR gaming enthusiasts. Anyone with a recent GPU (RTX 30/40 series, RX 7000 series) capable of 240Hz QHD. Skip it if you primarily use the monitor for productivity (OLED burn-in concern with static UI), if you need 4K resolution, or if your GPU can't drive 240Hz.

How to Use It

Enable G-Sync or FreeSync in your driver software. Calibrate HDR settings in your gaming profile. Use the monitor's pixel-cleaning cycle when prompted (auto-runs after extended use). Vary content over time — don't stay on the same desktop for hours. Connect via DisplayPort for Windows; HDMI 2.1 for consoles. Pair with a GPU capable of 240Hz QHD for full benefit.

How It Compares

Vs. ASUS PG279QM: PG279QM is comparable LCD-IPS at slightly lower price; LG's OLED has perfect blacks. Vs. Samsung Odyssey G8 OLED: Samsung is QD-OLED (different OLED type) at comparable price. Vs. ASUS ROG Swift PG42UQ (OLED): the 42" OLED is a 4K monitor for productivity-too. Different size class. Vs. older 144Hz IPS monitors: IPS is gray-black; OLED is true-black. Big difference.

Bottom Line

The right premium OLED gaming monitor for competitive PC and console use. Buy it for response time and HDR contrast. Skip it for productivity-only use or budget builds.
