Introduction
The Gigabyte MO27Q2A is a direct update of the MO27Q2, and the changes are small and easy to tell. Gigabyte increased the refresh rate from 240 to 280 Hz, upgraded the VESA ClearMR certification from ClearMR 13000 to ClearMR 15000, and left everything else unchanged. The Samsung QD-OLED panel, orientation, port selection, thermal management system, and OLED Maintenance feature are all set from its predecessor.
What makes the MO27Q2A worth testing as a standalone product is its position within Gigabyte’s OLED lineup. We reviewed the GO27Q24G recently, a $500 27-inch monitor built around LG’s WOLED panel with MLA+ technology. In relation to that monitor, the MO27Q2A adds an active USB hub, a KVM switch, and two 5 W speakers. It also increases the refresh rate by 40 Hz and slightly bumps the USB-C power delivery from 15 W to 18 W. The selling distance is the built-in circular polarizer of the WOLED panel, which allows WOLED displays to maintain deep blacks, which do not take side under ambient room light that QD-OLED can’t match except one. And the MO27Q2A’s bare glossy surface—by a meaningful margin—is the brightest surface I’ve encountered on any OLED monitor tested to date.
The panel is Samsung Display’s third generation of QD-OLED in 27-inch 1440p format, a platform that was launched at 360 Hz in 2024 and has since been available in bins with a refresh rate. The 280 Hz variant used here sits between the 240 Hz and 360 Hz versions of the same sub-panel technology. The subpixel layout is a triangular RGB arrangement common to all 27-inch 1440p QD-OLED panels currently on the market. Another is how that compares to the GO27Q24G’s WOLED sub-pixel layout in the picture quality section of this review.
At $600 in the US and €450 in Europe, the MO27Q2A occupies a clear niche: above the cheapest 1440p OLEDs, below the high-end panels using newer panel generations, and $100 above Gigabyte’s other WOLEDs. Let’s see what the test results say about whether that premium is worth it.
