Method 3: Update Graphics Driver

Graphics drivers are very important to maintain a sync of communication between the hardware and software. Hence, experts recommend that you keep the drivers of your PC updated at all times. There are three ways to update drivers:

  • Download updated drivers from the manufacturer’s website.

The Original Equipment Manufacturer or hardware manufacturer maintains an official website to provide resources to their customers. You must identify the hardware name and model number and download the relevant driver from these websites. Once downloaded, execute the file to install it on your PC.

  • Download updated drivers from Device Manager.

To simplify things, Microsoft has provided a built-in driver updater tool called the Deive Manager to help Windows users update the drivers. However, there is a limitation to this tool – it only looks for driver updates on Microsoft Servers. So, if the hardware manufacturer has not sent the updated driver for approval to Microsoft, you will not find the updated version through this method. Here are the steps:

Step 1: Press Win + X to open the Power Menu and choose Device Manager from the options.
Step 2: Click on Sound, Video, And Game Controllers to reveal your headset.
Step 3: Right-click on the HyperX Cloud 2 headset and choose Update Drivers.

It is not a too-technical method and does not have the limitation of looking for updated drivers on the Microsoft Servers only. Here are the steps to use this driver updater tool.

Step 1: Download and install Advanced Driver Updater using the link below.

Step 2: launch the app and click the Start Scan Now button.
