The question now is: why is this happening and does it have anything to do with G-Sync or FreeSync? NVIDIA has stated on a few occasions that there is more that goes into a VRR monitor than simply integrated vBlank extensions and have pointed to instances like this as an example as to why. Modern monitors are often tuned to a specific refresh rate – 144 Hz, 120 Hz, 60 Hz, etc. – and the power delivery to pixels is built to reduce ghosting and image defects. But in a situation where the refresh rate can literally be ANY rate, as we get with VRR displays, the LCD will very often be in these non-tuned refresh rates. NVIDIA claims its G-Sync module is tuned for each display to prevent ghosting by change the amount of voltage going to pixels at different refresh rates, allowing pixels to untwist and retwist at different rates.
