Nvidia's validation is more to do with their seal of approval than whether or not it will actually work.The anner as a 3D application needs appropriate resources to work smoothly: it need processor power, memory and also a certain amount of graphics memory. Nvidia will inform you that the display is not "validated" but the technology behind G-SYNC Compatible is the same technology behind FreeSync and Adaptive Sync. You can enable these "G-SYNC" settings even if you have a FreeSync or Adaptive Sync display. Enabling G-SYNC for multiple monitors can cause weird flicking issues. If you have multiple monitors, it's recommended to only enable it on the monitor you game on. The third section finalizes all your changes when you check Enable settings for the selected display model. If you have multiple monitors, the second section will show you what monitor you are currently modifying. Check the Enable G-SYNC, G-SYNC Compatible option and make sure you select Enable for windowed and full screen mode. If you have a G-SYNC display, you'll want to make sure it's enabled here as well as in the 3D Settings. There are a few more ways you can customize G-SYNC under this tab. There are some games (usually older ones) that shouldn't be run at very high framerates, for example.

This setting too can be used to curb power consumption. Max Frame Rate is similar to the first setting we looked at but it is in effect at all times if enabled. Still, every millisecond matters sometimes.

Nvidia recommends setting this to Ultra, but by their own testing, it doesn't seem to do very much in some of the most popular competitive games.

Low Latency Mode is useful if you're playing a competitive game like Fortnite where you want lag and latency to be as minimal as possible. However, increasing the resolution is very graphically intensive, so take care. This might sound like a useless setting, but it can be better than anti-aliasing at eliminating jaggy graphics. You could play a game at 4K and see it on your 1080p monitor, but you obviously wouldn't see a 4K image. Basically, it will render a game at a higher resolution and then downscale it to what resolution your monitor is. DSR - Factors (DSR standing for Dynamic Super Resolution) can be used instead of anti-aliasing to improve visual quality.
