34-inch QD-OLED ultra-wide monitor

The AOC AGON PRO AG346UCD is a 34-inch curved gaming monitor built on a QD-OLED panel with a 21:9 aspect ratio. It delivers a 3440 x 1440 resolution alongside a 175Hz refresh rate and a 0.03ms GtG response time. NVIDIA G-SYNC compatibility and DisplayHDR True Black 400 certification are included.

Competitive gamers wanting speed and HDR contrast

This monitor suits players who prioritise high refresh rates, near-instant pixel response and deep OLED black levels in an ultra-wide format. Buyers who need multiple HDMI inputs, integrated USB hubs or built-in speakers should look elsewhere. The stand offers 150mm height adjustment, tilt and swivel.

Single HDMI video port limits multi-source setups

The specifications list only one HDMI video connector with no additional DisplayPort or USB-C video inputs mentioned. This single port decides whether the display can serve as a primary screen for a PC while simultaneously accepting a console or second PC without a manual cable swap or external switch.
