How To Enable NVIDIA NULL For G-SYNC Monitors Correctly!

NVIDIA just updated NULL (NVIDIA Ultra Low Latency) Mode to support G-SYNC monitors. However, you need to set it up right to actually enjoy the benefits.

In this guide, we will share with you the benefits of turning on NVIDIA NULL, and how to turn it on for G-SYNC monitors!

How To Enable NVIDIA NULL For G-SYNC Monitors Correctly!


NVIDIA NULL (NVIDIA Ultra Low Latency) Mode

NVIDIA introduced NULL (NVIDIA Ultra Low Latency) Mode in the Gamescom Game Ready Driver in August 2019.

Before introducing NULL, NVIDIA has allowed gamers to reduce the number of frames in the render queue. This allows new frames to be sent to the GPU sooner, reducing latency and improving responsiveness.

NVIDIA NULL introduces just in time frame scheduling, submitting frames to be rendered just before the GPU needs them. This further reduces latency by up to 33%.

NVIDIA NULL response time testing

NVIDIA NULL mode has the most impact when the game is GPU-bound, with frame rates between 60 and 100 fps. It will enable you to enjoy better response times at high frame rates, without reducing graphics quality.



With the newly-released NVIDIA Game Ready Driver 441.08, NVIDIA NULL will now support G-SYNC for a better tear-free, extra-responsive variable refresh rate gaming experience.

This chart shows how end-to-end system latency is reduced by up to 20% when VSYNC is turned on, with both NVIDIA NULL and G-SYNC enabled.

Lowering the end-to-end system latency by 20% means a 20% faster reaction time from when you click the button on your mouse, to when the action appears on the display.

However, you cannot just turn on NVIDIA NULL for it to work with your G-SYNC or G-SYNC compatible gaming monitor.

How To Enable NVIDIA NULL For G-SYNC Monitors Correctly

Here is the proper method to enable NVIDIA NULL correctly for G-SYNC monitors :

  1. Download and install GeForce Game Ready 441.08 driver or newer.
  2. Open the NVIDIA Control Panel, and click on Manage 3D settings.
  3. Scroll down the Global Settings tab to Low Latency Mode.
  4. When you click on the options, you will have three choices :
    Off : The game’s engine will automatically queue 1-3 frames for maximum render throughput
    On : Limits the number of queued frames to 1
    Ultra : Submits the frame just in time for the GPU to start rendering
  5. Select the Ultra option for NVIDIA NULL

NVIDIA Control Panel NULL enable

  1. Scroll down to Vertical Sync and select On.


  1. Navigate to Set up G-SYNC on the left navigation list of the NVIDIA Control Panel.


  1. Enable G-SYNC for both windowed and full screen mode.
    Note : If your monitor supports both G-SYNC and ULMB, make sure G-SYNC is selected under the Monitor Technology drop-down list in Manage 3D settings.
  2. In your games, you must disable V-SYNC. This will allow the NVIDIA Control Panel to correctly enable NULL for your G-SYNC monitor.

That’s it! Now you can enjoy ultra low latency response times with a tear-free gaming experience on your G-SYNC monitor!
