240Hz OLED 1440p gaming monitor from LG drops to its lowest ever price in Amazon deal
Table of Contents
The LG UltraGear 27GS93QE is an excellent gaming monitor for players who want the image quality of an OLED monitor for immersive single-player titles, with the fast motion replication you’d want for competitive gameplay. Its 2560×1440 resolution, 240Hz refresh rate, 0.03ms quoted response time and broad adaptive-sync support make it particularly well suited to competitive gaming on a powerful PC. Typical full-screen brightness is modest compared with premium Mini LED monitors, but its perfect black levels, wide color gamut and two-year OLED-panel warranty help balance that limitation. Grab it now for just $499.99 – that’s $400 off the MSRP.
The complete monitor measures approximately 23.8 inches wide and 22.6 inches high at its listed stand position, with a depth of around 10.2 inches. A standard 100 x 100mm VESA pattern allows the original stand to be replaced with a compatible monitor arm or wall mount.

What we like about the LG UltraGear 27GS93QE OLED gaming monitor
Excellent motion clarity and a 240Hz refresh rate
LG quotes a 0.03ms grey-to-grey response time. Manufacturer response-time figures represent controlled best-case measurements rather than every possible transition, but OLED technology is inherently much faster than typical LCD panels. The result should be minimal conventional ghosting and clearer movement during rapid camera pans.

The 240Hz refresh rate is especially valuable in esports titles such as competitive shooters, racing games and arena games, where high frame rates can improve perceived smoothness and reduce the interval between an input and the resulting frame. It also makes desktop animation and pointer movement appear more immediate. A 240Hz OLED does not eliminate all visible motion blur because human visual persistence remains a factor. Nevertheless, it avoids the slow dark transitions that can affect some high-refresh VA monitors and the response-time variability found in many LCD panels.
LG includes Dynamic Action Sync, which is intended to minimise additional display-side input lag. An onscreen frame-rate counter and selectable Gamer, FPS and RTS presets provide quick access to different configurations, while a hardware crosshair can assist in games that permit such overlays.
Broad variable-refresh-rate support
The monitor is officially NVIDIA G-SYNC Compatible and supports AMD FreeSync Premium Pro. It also carries VESA AdaptiveSync certification, allowing its refresh cycle to follow the rate at which a compatible graphics card produces frames. This reduces tearing without introducing the fixed timing and potential stutter associated with traditional V-Sync. FreeSync Premium Pro additionally covers HDR and low-frame-rate compensation requirements on compatible AMD systems.
NVIDIA lists DisplayPort support with GeForce GTX 10-series and newer cards, while HDMI 2.1 variable refresh rate requires a sufficiently recent GPU. Actual refresh-rate ranges and feature support can depend on the selected input, graphics hardware and driver version.
The two HDMI 2.1 inputs also make the monitor suitable for a PlayStation 5 or Xbox Series console. Consoles cannot output 240Hz in current games, but they can use 1440p or downsampled 4K signals at up to 120Hz with compatible titles. The monitor’s maximum refresh rate is principally a PC feature.
Deep black levels and strong HDR contrast
The self-emissive OLED panel provides per-pixel light control, enabling bright objects to appear against a fully black background without halos. LG quotes a typical contrast ratio of 1,500,000:1, while VESA DisplayHDR True Black 400 certification confirms that the panel meets requirements designed specifically around emissive displays.
The “400” in DisplayHDR True Black 400 should not be interpreted as the monitor’s constant brightness. LG specifies typical SDR brightness at approximately 275cd/m², with peak highlights reaching substantially higher levels in suitable HDR content and small image areas. Brightness changes according to the size and duration of bright content because OLED displays use automatic brightness management to control heat and power.
This behavior means the 27GS93QE can produce impactful HDR highlights in dark or mixed scenes, but a mostly white webpage, document or game environment may appear less luminous than on a bright LCD. Users who work in strongly sunlit rooms may prefer a high-output Mini LED display, whereas the OLED performs best when room lighting is controlled.
The anti-glare and low-reflection finish helps suppress distracting reflections. It is useful in a gaming environment, although matte surface treatment can make the image appear slightly less glass-like than a glossy OLED panel.
Wide color coverage
LG specifies typical coverage of 98.5% of the DCI-P3 color space and support for approximately 1.07 billion displayable colors. This allows the panel to reproduce richly saturated HDR content and smoother gradients than a basic 8-bit display.
Wide gamut alone does not guarantee perfect color accuracy, and the most vivid gaming modes may intentionally exaggerate color. Users performing photography, graphics or video work should select an appropriate color mode and calibrate the monitor if dependable accuracy is required.
OLED’s wide viewing angles help preserve contrast and color when the screen is viewed from an offset position. This is useful when sharing the monitor or repositioning it.
Sensible connectivity for PC and console gaming
The rear connection panel includes two HDMI 2.1 inputs and one DisplayPort 1.4 connection. All three display inputs can support the panel’s QHD resolution at up to 240Hz when paired with appropriate source hardware.
A USB hub provides peripheral connectivity, and a 3.5mm headphone output allows audio arriving over HDMI or DisplayPort to be routed to a headset or powered speakers. The monitor does not include USB-C video input or laptop charging, so users seeking a single-cable notebook dock will need a separate adapter or docking station.
OLED protection and warranty
OLED monitors carry some risk of permanent image retention when static, high-contrast elements remain visible for extended periods. Desktop taskbars, application menus, channel logos and game HUDs are common examples. The 27GS93QE includes OLED Care functions intended to reduce that risk. Users can help further by enabling screen sleep, hiding static taskbars, using dark themes, varying content and avoiding unnecessarily high brightness for prolonged desktop work. These precautions should not prevent normal use, but the monitor is less suitable for continuously displaying the same productivity interface every day.
LG supplies a two-year limited UltraGear OLED warranty covering parts, labor and the OLED panel in the US listing. Warranty wording and burn-in treatment vary by region, so buyers should read the terms applicable to their country and retain proof of purchase rather than assuming that every form of image retention is automatically covered.
Who should consider this OLED gaming monitor?
The LG UltraGear 27GS93QE is best suited to PC gamers who value fast response, strong motion clarity and OLED black levels at a resolution that modern upper-midrange graphics cards can drive effectively. It is an especially good fit for someone who alternates between competitive multiplayer games and visually rich single-player titles.
It also works well as a mixed PC-and-console display thanks to its two HDMI 2.1 ports, DisplayPort connection and variable-refresh-rate support. QHD is sharp at 27 inches and offers a useful balance between detail and attainable frame rates.
Buyers primarily working with static spreadsheets, interfaces or dashboards for long hours may be better served by an IPS monitor without burn-in considerations. The same applies to brightly lit rooms where sustained full-screen luminance matters more than perfect black levels.
