To achieve the full 180Hz refresh rate with a laptop, you need to ensure that your laptop's graphics card supports this high refresh rate and that you are using a compatible connection method. The AOC CU34G2XP monitor supports 180Hz via DisplayPort, so using a DisplayPort connection is recommended. If your laptop only has HDMI ports, it may not reach the full 180Hz, as HDMI typically supports up to 100Hz or 144Hz for this monitor, depending on the specific HDMI version and laptop capabilities.

If your laptop supports DisplayPort output via USB-C with DisplayPort Alternate Mode, you might need an adapter to connect to the monitor's DisplayPort. However, not all USB-C ports support this feature, so check your laptop's specifications first.
