In this guide I will show you how to increase your screen refresh rate from 60Hz up to 80Hz at a native 1080p resolution. I've tried this on a G55VW and managed to make my display refresh at 80Hz, which is 1/3 times better than the stock clock of the built in monitor.
Just to note, since this was done using the Nvidia Control Panel, it should be applicable to a wide variety of hardware, but depending of the vendors and quality of materials of the hardware, the +20Hz I got may not be achievable to everyone.
Step 1:Right-click on your Desktop, open the Nvidia Control Panel and navigate to the "Adjust desktop size and position" menu.
Then click on the "Override the scaling mode set by games and programs" checkbox and apply the changes.
Step 2:Navigate to the "Change resolution" menu and click the "Customize..." button at the bottom.
Step 3:On the window that just opened for you, click the "Enable resolutions not exposed by the display" check box, and click on the "Create Custom Resolution..." button.
Step 4:Enter the value 80 (in my case) in the "Refresh rate (Hz):" field. And then click the "Test" button.
Step 5:Now here is when you understand if it will work. If it works, your display will flash and it will turn back on with the following message:
If it doesn't work, your display will stay dark. But don't worry, it will revert back the old settings after 20 seconds and it will turn on again. For it to work you have to experiment and see what Hz is your monitor is capable of displaying.
Step 6:Once everything is done, click the "OK" button and the custom profile will be saved.
Step 7:Head back to the "Change resolution" menu in the Nvidia Control Panel, click on the newly created profile and hit "Apply".
Now to test it if it all worksFind some place on your screen with a dark background, start moving your mouse and follow it with your eyes. Do this with both profiles, the 60Hz one and the 80Hz one (or in your case whatever you have for the custom profile).
You should see that the mouse pointer is less blurry, when moving it around, when the display is set to output 80Hz (or in this case whatever you have set it to).
