The AOC 27B31H is a 27 inch (68.6 cm) Full HD monitor built for home desks where screen space matters more than gaming extras. Its IPS panel gives 178° viewing angles both ways, a 1500:1 typical contrast ratio and 300 cd/m² brightness, so text and spreadsheets stay legible when the screen is viewed off-centre or shared with someone beside you.
- 1920 x 1080 pixels, 16:9, 82 ppi, 16.7 million colours
- 120 Hz maximum refresh rate with a 4 ms response time
- Single HDMI 1.4 input; AC and HDMI cables included
- VESA 100 x 100 mm mounting, 3.1 kg without the stand
Check two things before buying: your PC or laptop needs an HDMI output, as there is no DisplayPort or VGA, and neither AMD FreeSync nor NVIDIA G-SYNC is certified. On the stand it measures 616.6 x 445.5 x 191.9 mm and draws about 13.36 W in typical use. Available in South Africa from DistriNode.
Frequently asked questions
What inputs does the AOC 27B31H have?
One HDMI 1.4 port only. An HDMI cable is supplied. There is no DisplayPort, VGA or USB-C, so a laptop with only USB-C will need an adapter.
Can I mount it on a monitor arm?
Yes. It has a VESA 100 x 100 mm pattern and weighs 3.1 kg without the stand, which is within the range of common desk arms.
Is it suitable for gaming?
It refreshes at up to 120 Hz with a 4 ms response time, but it is not FreeSync or G-SYNC certified, so tearing control depends on your graphics settings.
The AOC 27B31H features a 27" Full HD (1920 x 1080) IPS display with a 120 Hz refresh rate and Adaptive Sync, designed to deliver smooth, responsive visuals for work and casual gaming. The monitor includes low blue light and flicker-free technology to reduce eye strain, and a 3-side frameless design that provides an expanded viewing area and a clean desktop appearance.
Advantages
High refresh rate and Adaptive Sync reduce motion blur and screen tearing, while the IPS panel ensures wide viewing angles and accurate colours. Eye-care technologies like low blue light and flicker-free operation support longer comfortable use. The slim, three-sided frameless design offers a modern look and minimizes bezel distractions.

Enable Adaptive Sync in your GPU settings if available.

Recommendations
For optimal results, pair the AOC 27B31H with a graphics card that supports 120 Hz output and Adaptive Sync. Position the screen at eye level and use recommended brightness and low blue light settings to reduce eye fatigue during extended use.
