Firmware updates are available for Acer Predator XB273U F5, AOC AGON PRO AG276QSG2, ASUS ROG STRIX Pulsar XG27AQNGV and MSI MPG 272QR X36 monitors with G-SYNC Pulsar.

You need an NVIDIA G-SYNC Pulsar monitor, a supported computing device (such as a PC, Mac or Android tablet or phone), a Micro-B USB cable from the monitor to your computing device and a supported web browser (such as Google Chrome).

You don't need to install an app. Just connect your monitor via USB to a supported device and open this page in a supported browser.

These browsers are currently supported:

  • Google Chrome 61 or newer
  • Microsoft Edge 79 or newer
  • Opera 48 or newer

The following operating systems are supported:

  • Microsoft Windows
  • Apple macOS
  • Linux
  • Google Android
  • Google ChromeOS

Note: Apple iOS is not supported

Updates typically take 5 to 10 minutes to install.

The app uses browser security features and only requests access to supported monitor USB devices. Like any firmware update, it must not be interrupted.

Using this official tool does not by itself change your monitor warranty. Warranty coverage is provided by the monitor manufacturer or seller, so check their warranty terms for details.

Be sure to carefully follow the connection instructions so that your monitor is switched into Firmware Update Mode. When the monitor is in this mode, the status light will flash slowly, and the screen will show Firmware Update Mode in the top-left corner.

If the app still doesn't connect to the monitor, there may be a problem with the USB cable. Ensure your cable supports data transfer, try reconnecting it or try a different cable.

The app will alert you. In most cases, it will allow you to retry safely.

In the unlikely case that your monitor won’t start, click "Update Monitor" and follow the recovery steps in the "My monitor won't start up" section.

In rare cases, after a failed upgrade, the monitor may fail to start up. To reinstall the latest firmware, click "Update Monitor" and follow the recovery steps in the "My monitor won't start up" section.

Accept the Terms of Service

By choosing to run this firmware update, you agree to the following, in addition to the NVIDIA Firmware License Agreement:

  1. Nature of the update and risk. This tool updates low‑level firmware on your G‑SYNC‑enabled monitor. If the update process is interrupted or fails (for example, due to loss of power, unplugging or moving cables, a system crash, or failure to follow the instructions), your monitor may malfunction, lose functionality, or become permanently unusable.
  2. Your responsibilities. Before starting the update, you are responsible for: (a) ensuring that your computing device (such as a PC, Mac, tablet or phone) and G‑SYNC‑enabled monitor are connected to a stable power source; (b) ensuring that all relevant cables (USB, display, power) are correctly connected; and (c) following all on‑screen instructions and not turning off or disconnecting your computing device or monitor, or unplugging any cables, until the tool confirms that the update is complete.
  3. Assumption of risk. You understand and agree that you run this G‑SYNC firmware update at your own risk, and that you, not NVIDIA, are responsible for any impact on your monitor or system resulting from an interrupted or failed update, except to the extent such responsibility cannot be limited under applicable law.
  4. No monitor warranty or replacement obligation. NVIDIA does not manufacture, sell, or warrant your monitor. Any hardware warranty for your monitor is provided by the monitor manufacturer or seller. To the maximum extent permitted by applicable law, NVIDIA does not assume any obligation to repair, replace, or provide any compensation for monitors or other hardware that are damaged, lose functionality, or become unusable as a result of the G‑SYNC firmware update process, and any such claims must be directed to your monitor manufacturer or seller. Nothing in these terms affects any rights you may have under your monitor warranty or under non‑waivable consumer protection laws.
  5. Incorporation of NVIDIA Firmware License Agreement. The NVIDIA Firmware License Agreement continues to apply to your use of this G‑SYNC firmware and update tool, including all warranty disclaimers and limitations of liability contained in that Agreement.
