Screen Resolution Switcher with QRes

This Python script uses QRes.exe to automatically switch between two screen resolutions and refresh rates based on the current display setting. If the screen is set to 1920x1080, it will switch to 1440x1080 (or vice versa) with the specified refresh rate. This is helpful for quickly toggling between custom display modes without needing to adjust settings manually.

Requirements

• Python 3.x: Make sure Python is installed. You can download it from python.org.
• QRes.exe: Download QRes.exe from SourceForge: QRes on SourceForge.

Installation

1. Download the Script:

   • Click on the green "Code" button in this repository.
   • Choose "Download ZIP" and save the ZIP file to your computer.
   • Extract the ZIP file to a folder of your choice.

2. Install QRes.exe:

   • Download QRes.exe from this SourceForge link and save it to a known location.
   • Make sure to note the full path to QRes.exe, as you’ll need it for the script configuration.

Setup

1. Specify the Path to QRes.exe:

   • Open the script file (qres.pyw) in a text editor.

   • Replace QRES_PATH with the full path to QRes.exe on your system:

     QRES_PATH = r"C:\path\to\QRes.exe"

2. Adjust Resolution and Refresh Rate Settings:

   • In the toggle_resolution function, you can customize the resolution and refresh rate. By default, the script toggles between 1920x1080 and 1440x1080 with a refresh rate of 165Hz. Modify these values as needed:

     set_resolution(1440, 1080, 165)
     set_resolution(1920, 1080, 165)

Usage

1. Run the Script:

   • Double-click on the qres.pyw script file to execute it. This will trigger an automatic resolution switch based on the current screen resolution.

2. Note on NVIDIA Control Panel Configuration (for custom resolutions):

   If you don’t see a custom resolution (like 1440x1080) after running the script, you may need to create this resolution in the NVIDIA Control Panel:

   • Open the NVIDIA Control Panel.
   • Go to Display > Change Resolution.
   • In the Change Resolution window, click on Customize below the list of resolutions.
   • In the Customize window, check Enable resolutions not exposed by the display.
   • Click Create Custom Resolution.
   • Modify ONLY these fields in the Display Mode (as reported by Windows) section:
     • Horizontal pixels
     • Vertical lines
     • Refresh rate (Hz)
   • After setting the fields, click Test. Once validated, your custom resolution will appear in the list, making it usable by QRes.

Important Notes

• Supported Resolutions: If QRes doesn’t switch to a specified resolution, ensure the resolution is supported by both your monitor and graphics card settings.
• Custom Resolutions: Some custom resolutions may need to be created manually (as described above) in the graphics settings for QRes to recognize them.
• Laptops: Often some laptops do not have a Display > Change Resolution section, usually this section appears when the monitor is connected.
