Main trade-off
AOC 27-inch Mini-LED Gaming Monitor

Head-to-head
AOC Q27G3XMN vs Gigabyte M27Q: AOC adds HDR backlight control, Gigabyte lets two computers share peripherals
The short answer
Q27G3XMN uses Mini-LED local dimming and DisplayHDR 1000 for more convincing HDR. M27Q gives up that backlight control in exchange for IPS viewing, USB-C and a KVM.

About this comparison
Two value QHD gaming monitors spend their feature budget on HDR or desk switching.
The practical choice turns on panel and backlight and hdr tier, then on the constraints in your own setup.
Before you choose
How they fit your plans
A keyboard and mouse fill the Gigabyte’s two downstream sockets
M27Q’s KVM can help a work computer and gaming PC share the desk, but a separately wired keyboard and mouse occupy both USB 3.0 downstream ports. A webcam, editing drive or other USB accessory then needs another connection. Choose Gigabyte for this switching job with that peripheral budget understood. Choose AOC around its display requirements when the computer already handles all peripherals independently.
Facts behind this advice
The catalog-linked M27Q revision 2.0 specifies KVM and two USB 3.0 downstream ports. Two individual devices consume two ports, without assuming a shared wireless receiver.
HDR capability does not replace a native 4K review screen
AOC’s local-dimming hardware and HDR certification can be relevant to viewing HDR material, but the panel is still QHD. Neither monitor can show an entire 4K frame pixel-for-pixel on its native grid. Choose AOC when the documented HDR hardware is the priority and reduced preview size is acceptable. Choose Gigabyte for its shared-computer workflow, or leave this pair if full-frame native 4K inspection is essential.
Facts behind this advice
Both panels are 2560 by 1440. AOC documents 336 dimming zones and DisplayHDR 1000. These facts do not establish reference-grade HDR mastering or measured calibration accuracy.
Winner by situation
Start with what you need it to do
High-impact HDR without an OLED panel
For panel and backlight, AOC 27-inch Mini-LED Gaming Monitor records “VA with 336-zone Mini-LED” and Gigabyte M27Q 27-inch QHD Gaming Monitor records “IPS with edge lighting”. This changes setup and daily operation more than the product's core physical job.
