Rank #7 in Best Ultrawide Curved Gaming Monitor 2026: 10 Ranked by Spec Sheets
AOC CU34G2XP/BK 34in UW-QHD 180Hz Curved Monitor
Price and rating as shown on Amazon when we collected them. Both change.
The AOC CU34G2XP/BK is a 34-inch curved ultrawide gaming monitor: 3440 x 1440, a 21:9 panel, a listed 180 Hz refresh rate and VESA DisplayHDR 400. It comes seventh in this guide at £219.97, with a 4.3 average from 1,227 ratings on the Amazon listing.
The listing argues with itself over response time. The title and the second bullet both claim 1ms GtG; the spec table's own Response Time field reads '5 Milliseconds'. The same table gives a Total HDMI Port figure of 1, while the title advertises 'HDMI 2x 2.0'. Everything on this page is taken from the Amazon listing for this monitor — the figures, the price and the buyer quotes — and not from any test we ran.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“Good gaming displace, great size and with HDR have always used AOC screens and never failed me. Colour quality is strong and clear, very responsive with hardly any loss or delay. Great quality for money. Highly recommended”
Verified purchase“Does exactly what it says. Excellent value. 4K would need much stronger hardware which takes your total cost up, because you would need more expensive graphics cards to run 4K. So 1440p is still the sweet spot.”
