AOC Q27G4XY 27" Smart Gaming Monitor QHD Fast VA 180Hz 1ms | Google TV OS | Adaptive Sync | Dolby Audio | USB-C 65W | DP 1.4
Description
The AOC Q27G4XY is a 27-inch smart gaming monitor combining a Fast VA QHD panel, Google TV OS, Adaptive Sync, built-in Dolby Audio, USB-C, and gaming-focused features. One important correction: the official AOC and Singapore store specifications list the monitor at up to 180Hz, while 144Hz applies over HDMI 2.0 at QHD.

Smart TV Features
The standout feature is Google TV OS, which turns the monitor into a standalone entertainment display. It provides access to streaming apps, movies, TV shows, live TV, sports, and other Google TV content without requiring a PC. Google Assistant/AI voice support also enables voice-based content search and control.
Other smart features include:
- Google TV OS
- Google Assistant / AI Voice Assistance
- Wi-Fi
- Miracast
- Streaming apps
- Voice search
- Smart entertainment without a PC
Gaming Performance
AOC lists the Q27G4XY at 180Hz maximum refresh with 1ms GtG response, Low Input Lag, Adaptive Sync/FreeSync, and G-SYNC Compatible support on its regional product pages.
For input-specific refresh rates, a Singapore retailer lists:
- 2560 × 1440 @ 180Hz via DisplayPort 1.4 / USB-C
- 2560 × 1440 @ 144Hz via HDMI 2.0
- 1920 × 1080 @ 60Hz in Android/Google TV mode
So your supplier title using 144Hz is not necessarily wrong, but it describes the HDMI QHD rate rather than the monitor's overall maximum refresh rate.
Connectivity
There is some regional variation in AOC listings, so the Singapore-market configuration is the safest one for your likely SKU:
| Port | Quantity |
|---|---|
| HDMI 2.0 | 1 |
| DisplayPort 1.4 | 1 |
| USB-C with DP Alt Mode | 1 |
| USB-C Power Delivery | Up to 65W |
| USB-A 3.2 Gen 1 | 2 |
| Earphone Output | 1 |
AOC's North American regional page lists a different connectivity configuration, including HDMI 2.0 ×2 and DP 1.4 ×1 without USB, which indicates regional SKU differences. For a Singapore listing, use the Singapore configuration unless your supplier confirms otherwise.
USB-C 65W
The USB-C port supports:
- DisplayPort Alt Mode
- Video transmission
- Data connectivity
- Up to 65W laptop charging
This makes the Q27G4XY suitable for both smart entertainment and productivity setups.
Built-In Audio
The monitor has:
- 5W ×2 speakers
- Dolby Audio
- Earphone output
This is a major advantage for Google TV use because external speakers are not required for basic streaming and entertainment.
