The short version
- Panel: The GO27Q24G is a 27-inch, 2560×1440, 240 Hz monitor using an LG Display WOLED panel with Micro Lens Array+ (MLA+).
- Brightness claim: Gigabyte quotes 275 nits standard brightness and up to 1,300 nits peak. The review's spec table attaches that figure to a 1.5% window, so it describes a small highlight and not a full screen.
- Price: Tom's Hardware lists $349.99 at Amazon at publication. Pricing has moved around since launch. Wccftech reported a $399 launch price on Amazon. A Best Buy listing showed $374.99, marked down from $499.99. Check the live price before you buy.
- Omissions: There are no USB ports, no internal speakers and no RGB lighting. There is a 3.5 mm headphone output.
Why WOLED, and what the MLA does
White OLED makes color with filters over a white emitter, not with RGB stripes or Quantum Dots. That costs a bit of color volume, and the reviewer says as much. Tom's measured about 96% of DCI-P3, and a later color test approaches 100%. Quantum Dot and Tandem OLED rivals still have more color volume. Gigabyte's own page claims 99% DCI-P3.
The Micro Lens Array is how a budget WOLED reaches these brightness numbers. The review describes it as a textured layer of roughly 5,000 tiny lenses over each pixel that pushes more light toward the viewer. It also says the layer helps power draw and viewing angles. The reviewer's side-on photo showed no change in color, brightness or gamma. The monitor drew 30.5 W at 200 nits.
Brightness: read the window size
Peak 1,300 nits figures get misread all the time, so here is how Tom's tested it:
- HDR mode (default): about 465 nits on a 25% window, which earns the HDR400 certification.
- Peak 1300 mode: over 728 nits on a 25% window.
- Gigabyte's 1,300-nit claim: this refers to a 1.5% window. The reviewer saw no reason to doubt it.
The reviewer notes that on many OLEDs, modes named "Peak 1000" are no brighter than ordinary modes. Here the Peak 1300 mode really is brighter. There's a catch, though. Peak 1300 is the more impactful mode, but the standard HDR mode tracks the luminance reference more accurately because Peak 1300 lifts the midtones. So choose Peak 1300 for punch, as the reviewer did in Doom Eternal. Choose standard HDR for accuracy.
Gigabyte also advertises HyperNits, which it says boosts brightness by up to 30% in Peak 1300 mode while preserving highlight detail. The review as supplied doesn't test that feature separately, so treat it as a manufacturer claim.
Speed and input lag
- Pixel response: the comparison group (Sony INZONE M10S II, ViewSonic VX2738-2K, Gigabyte MO27Q28G and Alienware AW2726DM) showed black-to-white times of 0.16 to 0.24 ms. The Asus XG27AQWMG was left out because it wasn't tested with the Nvidia LDAT sensor.
- Context: the reviewer says these differences are invisible to the eye. The 540 Hz Sony was 0.04 ms slower than the 280 Hz MO27Q28G, so a higher refresh rate doesn't guarantee faster pixel response.
- Input lag: the GO27Q24G came out on top by 0.5 ms. The reviewer concedes that is below human perception.
- Motion: the review says there is no visible motion blur above about 200 fps. Below 120 fps, the Ultra Clear black-frame-insertion mode helps, but it cuts brightness by around 40%.
The "competition weapon" language and the claim of near-perfect aim are the reviewer's subjective impressions, tested with a GeForce RTX 4090. They are not evidence that the monitor improves anyone's skill. Most readers won't hold 200+ fps at 1440p on a mid-range GPU in demanding titles, which makes Ultra Clear and the FHD modes more relevant than the headline numbers suggest.
Setup and calibration
Out of the box, the review found Standard mode slightly warm, with gamma that was too dark. The reviewer's fix:
- Set the picture mode to Standard.
- Change gamma from 2.2 to 2.0.
- Set color temperature to User and enter Red 95, Green 100, Blue 99.
- Set brightness to taste. The reviewer's values were 76 for about 200 nits, 41 for 120 nits, 33 for 100 nits, 24 for 80 nits and 12 for 50 nits. The minimum is about 24 nits.
- If you need sRGB, pick the dedicated sRGB picture mode from the 10 presets. Only brightness is adjustable there.
These numbers come from one review unit and one room, so treat them as a starting point. After calibration the review reports 1.04 dE and 105% sRGB coverage, which the reviewer attributes to a little extra red.
OSD quirks worth knowing
- APL Stabilize (OLED Care menu): this is the variable-brightness control, and the naming is confusing. Low effectively turns the dimming behavior off, which gives constant brightness. High gives the most contrast and the brightest highlights, and suits HDR and SDR video.
- Tactical Switch: it drops to FHD, either full screen or in a 24-inch window. The reviewer prefers the window because it maps pixels 1:1 and avoids scaling softness. You get black borders and can position the image top, center or bottom.
- Button caution: the left button beside the joystick is power. The right one triggers the Tactical Switch.
- OLED care: pixel orbiting, schedulable cleaning routines, logo and corner dimming.
- PIP/PBP is available. The four joystick directions can be assigned to shortcuts.
Build, ports and ergonomics
The stand is all metal and tool-free to assemble. Adjustments are 5/21 degrees of tilt, 15 degrees of swivel, portrait rotation and 5.1 inches of height. VESA is 100 mm, and the reviewer notes you'll need to supply your own fasteners.
Inputs are two HDMI 2.1 ports, one DisplayPort 1.4 with DSC and one USB-C. The USB-C input supplies 15 W. The reviewer's list of what's in the box includes a DisplayPort cable.
Who it suits, and the caveats
Good fit:
- Gamers who want OLED motion clarity and contrast without the $600+ price.
- Anyone who plays mostly in a dim or controlled room, where small bright highlights stand out.
- Console and slower-PC users who can use Ultra Clear.
Think twice if:
- You want a built-in USB hub or speakers.
- You want the widest possible color volume. Quantum Dot and Tandem OLED models do better there.
- You'll spend long hours on static desktop content. Gigabyte's OLED care features reduce burn-in risk but don't eliminate it. This is general OLED knowledge, not a finding from the review.
- You can't spend time on calibration, since the factory image runs warm and dim.
Bottom line
On the evidence of the Tom's Hardware review, the GO27Q24G is a real value play. It combines a fast 240 Hz OLED, bright small highlights and a sturdy metal stand, and it asks for little in return beyond a few minutes in the OSD. It leaves out USB and speakers, and its peak brightness number needs the window-size context above. Cross-check the live price, since it has varied between about $350 and $399 across listings.
