The product, explained
About the AOC CU34G4
AOC CU34G4 is listed in the computer monitors category. The recorded specifications include display diagonal: 86.4 cm (34"); display resolution: 3440 x 1440 pixels; panel type: Fast VA; maximum refresh rate: 180 Hz. This entry covers manufacturer code CU34G4. Specifications relate to this exact source record; other editions or packages may differ.
The 86.4 cm (34") display is specified at 3440 x 1440 pixels. Consider these together: a larger screen provides more physical space, while resolution determines the number of pixels available. Neither specification establishes brightness, colour accuracy or motion quality.
The listed maximum refresh rate is 180 Hz. To use it, the source device, cable, resolution and input must all support the intended mode. Refresh rate is separate from response time and input lag.

Where can I compare prices for AOC CU34G4?
Use the retailer-offer section on this page for available matched offers. If no offer is shown, we do not currently have a verified price. Confirm model, stock, delivery and the final total at the retailer; coverage does not include every seller.

Not necessarily. Check the laptop port supports the required display mode and charging level.
