Changing Freesync range with the help of CRU

Josh Maynard

Cru, or Custom Resolution Utility, is a tool developed by the tech community to modify monitor settings, including refresh rates and FreeSync ranges, on certain monitors that have AMD FreeSync technology.

You can download CRU by clicking on the link.

NOTE: It’s essential to note that using third-party tools like CRU can potentially void your monitor’s warranty and may carry some risks if not used correctly. Always proceed with caution and refer to your monitor’s documentation and manufacturer’s guidelines.

It is also important to remember that not all monitors support the modification of the FreeSync range through CRU, and even for those that do, results may vary. Some monitors may have hardware limitations that prevent extensive customization of the FreeSync range.

Moreover, exercise caution when using CRU because incorrect settings could potentially damage your monitor or make it unusable. Always make sure to back up your monitor’s original settings and do thorough research on forums and resources dedicated to your specific monitor model before attempting any modifications.

Why you might need to change your freesync range

Changing your monitor’s variable refresh rate (VRR), such as FreeSync , can have several advantages for gamers and users who want a smoother and more responsive experience. Here are the primary benefits:

  • Reduced Screen Tearing: VRR technologies sync the monitor’s refresh rate with the GPU’s frame output, eliminating screen tearing. Screen tearing occurs when the monitor displays parts of two different frames simultaneously, which can be distracting and immersion-breaking in games.
  • Smoother Gameplay: VRR eliminates stutter and judder by dynamically adjusting the monitor’s refresh rate to match the varying frame rates produced by your GPU. This results in smoother and more consistent gameplay, especially when frame rates fluctuate.
  • Lower Input Lag: VRR can help reduce input lag by ensuring that the monitor is displaying the most recent frame from the GPU as soon as it’s ready. This leads to quicker response times in games and a more responsive feel when using your computer.
  • Improved Visuals: By eliminating tearing and stuttering, VRR can enhance the overall visual quality of games and videos, making them look more fluid and enjoyable.
  • Enhanced Compatibility: VRR technologies like FreeSync and G-Sync work with a wide range of GPUs and monitors, making it easier for users to achieve a tear-free and smooth gaming experience without worrying about specific hardware requirements.
  • Extended Usability: VRR can make lower frame rates more bearable, allowing you to play games and use applications even on less powerful hardware without sacrificing the overall experience.
  • Better Multi-Monitor Setups: In multi-monitor setups, VRR can help ensure that all monitors refresh at the same rate, reducing visual discrepancies and providing a more consistent experience.
  • Support for HDR: Some VRR monitors also support High Dynamic Range (HDR) content, enhancing the quality of HDR gaming and video playback by synchronizing the display’s refresh rate with the content’s frame rate.

You can use two different methods to change the Freesync range, which are mentioned below:

Displayport

If you’re using DisplayPort, follow these instructions to modify the FreeSync range.

  1. Run CRU.exe after downloading and unpacking the contents from the aforementioned website.
  2. Choose your monitor from the drop-down option at the window’s top. It will be marked as ‘active’.
  3. Select “Edit” next to the model name of your monitor.
  4. It will open the “Display Properties” panel. Simply enter the desired value in the box next to “V rate” under “Range limits” to modify the VRR range. Lastly click “OK.”

Next up

  1. Run restart64.exe to reset your graphics driver and apply the adjustments after that.
  2. There will be a few blackouts on your monitor.
  3. Simply press “F8” to undo changes if you unintentionally input a frequency that the monitor doesn’t allow and the image isn’t back after 15 seconds.

You are done now!

When you want to adjust the VRR range once more, you can repeat the procedure.

Just as with overclocking, keep in mind that some monitors won’t allow you to extend the range.

If you increase the range of a monitor with a 40-75Hz range to 30-75Hz, it might operate wonderfully, while another unit of the same display might not even support 39-75Hz.

HDMI

You’ll need to change the extension block if you’re using FreeSync over HDMI.

  1. Select “FreeSync range” in the “Extension Block” window, then click “Edit.”
  2. Enter the desired range in each of the three windows and press “OK.”
  3. Once you’ve run restart64.exe, you’re done!
