I'm using an Acer XB253Q GW monitor, which supports up to 280Hz refresh rate. However, on Windows, I'm unable to set the refresh rate above 120Hz. When I try to select 240Hz or 280Hz, the screen goes black, shows "no signal," and then reverts back to 120Hz.

I’ve already:

  • Installed the official Acer driver (INF and ICM files),
  • Verified I’m using a proper DisplayPort 1.2 or higher cable (not HDMI),
  • Tried using CRU (Custom Resolution Utility) to define a higher refresh rate, but 280Hz is marked in red and not accepted,
  • Set custom FreeSync range and detailed resolutions,
  • Used DDU to clean and reinstall GPU drivers,

    Let's say the screen refresh rate is 300hz. If your graphics adapter does not support this value, it will give a no signal error. The hz value of the screen is related to the graphics adapter.

    It seems that your graphics card supports a maximum refresh rate of 120hz. Please let us know the model and name of the graphics adapter, whether you are using a laptop, workstation, desktop, etc., and we will send you the details.
