Gigabyte GO27Q24G review: Fast gaming, HDR trade-offs

The Gigabyte GO27Q24G is a 27-inch QHD WOLED monitor built for high-refresh-rate gaming: GIGABYTE specifies up to 240 Hz, and Tom’s Hardware reviewer Christian Eberle measured a 0.24 ms black-to-white response and 13.1 ms of absolute input lag. HDR can look brighter in Peak 1300 mode, but it tracks luminance less accurately; reviewers also report that fine text can show fringing.

For competitive PC gaming, that mix makes the GO27Q24G a compelling speed-focused option. For long stretches of desktop work, text clarity deserves more attention. And if you care about HDR accuracy as much as impact, the regular HDR preset is the better fit.

Measured speed, beyond the GTG figure

GIGABYTE lists a 0.03 ms gray-to-gray (GTG) response time. Eberle’s 0.24 ms result measures a black-to-white transition, a different test; his review also reports 13.1 ms of absolute input lag. Those results give a more useful picture of the tested monitor’s gaming performance than treating the two response-time figures as interchangeable. (GIGABYTE specifications; Tom’s Hardware test results)

In Eberle’s comparison group, black-to-white response results ranged from 0.16 to 0.24 ms. He said the differences were not visible to the naked eye. His review also described a smoother gaming experience when frame rates exceeded 200 frames per second, making a fast gaming PC the clearest match for the monitor’s 240 Hz ceiling.

HDR: more punch or closer tracking?

The regular HDR preset measured about 465 nits at a 25% window in Eberle’s test. Peak 1300 measured more than 728 nits at the same window size, but raised midtones and tracked the EOTF—the curve that maps an image signal to screen brightness—less accurately. Choose the regular HDR preset when luminance accuracy matters more; use Peak 1300 when you prefer a brighter-looking image. (Tom’s Hardware HDR test)

GIGABYTE’s own figures describe different conditions: typical brightness of 1,300 cd/m² at HDR 1.5% APL and 275 cd/m² at SDR 100% APL. APL, or average picture level, describes the overall brightness of the displayed image. Those manufacturer specifications should be kept separate from the review’s 25% window results.

The monitor’s APL Stabilize menu offers Low, Middle and High settings. The pictured OSD shows where those controls sit; it is a menu, not a brightness measurement.

Calibration and text clarity

Eberle measured grayscale error of 4.03 dE on his review sample in its default settings, then 0.81 dE after calibration. His Standard-mode recommendations pair brightness settings with luminance targets; they are useful starting points, not a guarantee that every unit will measure the same.

Fine text is a separate tradeoff. In his hands-on review, The Display Guy described text clarity as weak because of the panel’s subpixel arrangement. That is an individual reviewer’s observation, not a standardized severity score. The same reviewer praised the glossy coating’s clarity, while the glossy surface can reflect direct light. If you spend more time reading and editing than gaming, text rendering is worth checking against your own needs before choosing this display. (The Display Guy’s review; Tom’s Hardware review)

Gaming tools, connections and warranty

The GO27Q24G has two HDMI 2.1 ports, one DisplayPort 1.4 connection, USB-C and a headphone output. Tom’s Hardware reports 15 W of USB-C power delivery and DisplayPort DSC support. USB-C is an input, not a multiport hub: the monitor has no additional USB ports or internal speakers. (GIGABYTE specifications; Tom’s Hardware review)

For lower frame rates, Tom’s Hardware says Ultra Clear black-frame insertion works below 120 Hz and reduces brightness by about 40%. The monitor also offers gaming overlays and Tactical Switch, which provides resolution options through the on-screen menu. (Tom’s Hardware review)

GIGABYTE states that the monitor’s three-year warranty includes panel burn-in coverage. (GIGABYTE specifications)

US price record

Tom’s Hardware listed the GO27Q24G at $349.99 on Amazon in review pages published October 12, 2026. Best Buy’s listing says the monitor is no longer available new. (Tom’s Hardware price listing; Best Buy listing)
