 You may need to tweak your GPU settings to stretch images (e.g., scaling options in NVIDIA Control Panel). You may also need to experiment with [CRU](https://www.monitortests.com/forum/Thread-Custom-Resolution-Utility-CRU) - again, YMMV if it will help.
 
+## Workaround for submonitors that can't do 60Hz
+
+As mentioned above, the game will end up with a white screen if the subscreen does not properly support 60Hz.
+
+If you bought a touchscreen monitor and it can't do 60Hz properly (instead can only do 70Hz, for example), you can try the new `-graphics-force-refresh-sub` option, and enter the desired refresh rate of your monitor. This will force the game to launch the subscreen display adpater in that refresh rate instead of 60Hz.
