# How to Use Native Resolution in Fullscreen with G-Sync Enabled
I found a solution for the issue where a game does not offer the monitor's native resolution in fullscreen mode when G-Sync is enabled. Many solutions found online recommend disabling G-Sync, but in my opinion, this is not the best approach.
The actual problem appears to be that, with G-Sync enabled, the game falls back to the wrong resolution list. Instead of using the monitor's native resolutions, the game accesses a fallback list containing standard TV resolutions.
The solution is to remove the incorrect resolution entry that the game uses when G-Sync is enabled. This allows the game to use the monitor's native resolution list again.
This is a clean and reversible solution, so it can also be safely tested. The changes can be restored at any time.
My Setup
In my case, I am using a monitor with the following configuration:
Resolution: 2560 × 1440
Refresh rate: 144 Hz
G-Sync: enabled
With this configuration, the game only offered 1920 × 1440 in fullscreen mode.
Here is how I fixed the problem.
What You Need
You will need CRU – Custom Resolution Utility by ToastyX.
CRU is a utility that allows you to manage a monitor's resolution and display profiles. It does not need to be installed and can be launched directly using CRU.exe.
# Step 1 – Select Your Monitor
Start CRU.exe.
At the top of the window, use the dropdown menu to select the monitor you are having the issue with.
You will then see several sections. At the bottom, there is an “Extension Block” section.
Inside it, you will find an entry called “CTA-861”. Open it by double-clicking it.
# Step 2 – Check the TV Resolutions
Inside the CTA-861 window, look under Data Blocks for “TV resolutions”.
This is where the problem occurs in my case. With G-Sync enabled, the game falls back to an incorrect entry from this list.
For my monitor, the problematic entry is:
1920 × 1080 (16:9) @ 120 Hz
To generalize this, it appears to be the entry with the highest resolution and highest refresh rate in this list.
However, monitors can have different resolutions and refresh rates, so you should not simply look for 1920 × 1080 @ 120 Hz. The important thing is to identify the corresponding problematic entry in your own TV resolutions list.
# Step 3 – Delete the Incorrect Entry
Select the corresponding entry and click “Delete” underneath the list.
Then click “OK” until all open windows are closed and you are back on the desktop.
# Step 4 – Restart the Graphics Driver
Now run restart64.exe, which is included in the CRU folder.
This will restart the graphics driver and refresh the display configuration.
You can now launch the game again.
The desired native resolution should now be available in fullscreen mode, while G-Sync can remain enabled.
In my case, this restored the native 2560 × 1440 resolution in fullscreen mode while keeping G-Sync enabled.
# Reverting the Changes
If you are unsure about the changes, if the solution does not work for you, or if you simply want to restore the original settings, you can run reset.exe from the CRU folder.
This restores the standard/default display settings and removes the changes made through CRU.
If deleting the first entry does not solve the problem, you can also try removing other resolutions from the “TV resolutions” section and testing them one by one.
Since the changes can be reverted using reset.exe, this also provides a safe way to identify which entry is causing the problem with your particular monitor and G-Sync configuration.
# Summary
The problem does not necessarily lie with G-Sync itself. Instead, it appears that when G-Sync is enabled, the game falls back to an incorrect entry from the TV resolutions fallback list.
Removing that entry allows the game to use the monitor's native resolution again without having to disable G-Sync.
The change is fully reversible, so you can restore the original settings at any time using reset.exe.
