LG 27GX704A-B Monitor Review
Bottom Line
The LG 27GX704A-B delivers standout glossy OLED clarity, inky blacks and effortless 240Hz gaming at attractive sale prices. Mirror-like glare, fuzzy text and reported PS5 HDMI handshake problems limit its versatility.
PC and PS5 gamers who prioritize responsive 1440p OLED visuals and strong contrast, especially when they can control direct room reflections. Discount shoppers upgrading from LCD benefit the most.
People spending most of the day reading code or spreadsheets, users with sensitive eyes, and anyone placing the screen opposite bright windows. Buyers who need USB-C docking or effortless PS5 input switching should be cautious.
Verdict
The LG 27GX704A-B is a compelling entry into glossy OLED gaming. At 27 inches and 1440p, its 240Hz WOLED panel offers outstanding motion clarity, responsive controls, deep blacks and crisp, low-haze image quality. Many owners and testers especially appreciate how well its blacks hold up with room lights on, and sale pricing makes the package easier to recommend. It also brings full-bandwidth HDMI 2.1 and a flexible stand. There are real compromises, though: glossy reflections can become distracting near windows, the WOLED subpixel structure makes text look fuzzy, and newer Tandem OLED or QD-OLED rivals deliver more saturated HDR color. HDR presets can also clip detail or appear dull, depending on the source. A long-term owner reported persistent PS5 signal detection failures and a sometimes unresponsive OSD joystick. For gaming-first buyers willing to manage lighting, its strengths are considerable; text-heavy office work is less persuasive.

Pros highlights
-
Owners and testers are largely enthusiastic about the exceptional gaming picture and sale-price value. Persistent HDMI handshake trouble and office-use compromises remain important.
-
At sale prices around $380–$500, the glossy 240Hz OLED package gets strong value praise. Its higher launch pricing looks less competitive beside newer models.
-
Rapid motion and moving targets look exceptionally sharp, particularly at high refresh rates. A low-frame-rate user anecdote flags stutter sensitivity.
-
A high-refresh OLED with exceptionally clear motion and deep blacks makes PC gaming the primary strength. The 240Hz panel keeps action responsive.
-
The glossy coating is a standout: crisp, low-haze images look substantially cleaner than older matte WOLED finishes.
-
OLED brightness is strong in many games and HDR highlights, but not consistently the brightest among newer Tandem OLED screens. Strong direct light can still overwhelm visibility.
Cons highlights
-
The crisp glossy surface also reflects windows and lights clearly. Daytime usability depends heavily on screen position and light control.
-
Some faint vertical/gray banding and mesh texture can appear on test patterns. One owner found the issue barely noticeable in normal use.
-
One owner repeatedly encountered a blank PS5 HDMI signal until restarting the display; console modes can also require manual selection for 4K/120Hz.
-
The WOLED subpixel layout can put colored edges around letters and make them look fuzzy. ClearType helps but does not fully match IPS text.
-
A bottom-center joystick works in open setups but becomes hard to reach with another screen underneath. A later owner found wake activation less responsive.
-
Flicker sometimes appears when refresh rates fluctuate in dark scenes or even when moving windows; it is not constant in most fast-paced games.
Use Cases
Best for
-
Sale pricing makes premium-looking OLED gaming comparatively accessible, though the original higher price changes the value equation.
-
Deep blacks and bright colors make films, streaming video and high-production-value YouTube content especially impressive.
-
The switch from IPS or conventional LCD brings much better black depth, color impact, and motion clarity, especially in dark games.
Not ideal for
-
USB-C laptop dockingNo USB-C video input makes one-cable laptop docking impossible and reduces appeal for laptop-centric desks.
-
Dual-monitor setupsStacked monitor arrangements can block the bottom-mounted joystick and require moving the second display to change settings.

Compared in Reviews
Products reviewers directly compared with this model, grouped into quick takeaways.
- Compared: brightness in specific scenes The older WOLED sometimes measures brighter in select scenes, but its newer sibling is generally brighter.
- Better: launch price versus specification value At launch, the 27GX704A sat only $50 below the more capable 27GX700A.
- Alternative: brightness, color, stand, coating Tandem OLED is brighter and more vivid; the LG glossy sibling wins clarity and ergonomics but reflects more light.
- Alternative: higher refresh, color and HDMI bandwidth The Alienware alternative is faster and more colorful but lacks the LG’s full HDMI 2.1 bandwidth.
- Worse: bright-room contrast and HDMI 2.1 The LG is favored in illuminated rooms and for HDMI 2.1 connections; the Dell offers QD-OLED color purity.
FAQ
Is the LG 27GX704A-B good for competitive gaming?
Yes. Its 240Hz refresh, near-instant OLED response, low input lag and VRR support keep fast action sharp and responsive.
How reflective is the glossy coating?
It delivers exceptionally clear images but can act like a mirror around bright windows or direct lights. Black depth remains strong in moderate ambient light.
Does it work well with a PS5?
Games look excellent and HDMI 2.1 supports high refresh and VRR, but one long-term owner repeatedly had to restart the monitor when it failed to detect the PS5 signal.
Is the 1440p screen suitable for office work and coding?
Basic productivity works, but its WOLED subpixel layout can make text fuzzy or fringed. Conventional IPS screens are a better fit for extended text-heavy tasks.
How good is HDR on this monitor?
OLED contrast produces impactful highlights, but color volume and HDR tone mapping trail some newer OLED models. Some presets clip detail, and one owner found Windows HDR dull.
Is burn-in a problem after months of use?
One owner saw no visible burn-in after over 700 hours with static interfaces; OLED shift and cleaning tools seem helpful. That is encouraging short-term evidence, not a guarantee against future burn-in.
Is it worth buying at a discount?
Discounts around $380–$500 received strong praise for bringing glossy OLED gaming within reach. At prices close to newer Tandem OLED competitors, the value argument weakens.
