Forte is designed to prioritize your audio signal. If you are experiencing a grainy or pixelated image, this may be caused by an unstable internet connection.
The most common signal strength issue is due to the router being blocked by another object. If your router is near other electronics, or if there is another object (small or large, including floors and walls) between you and the router, try moving it to avoid connection disruptions. Sitting closer to your router always helps, and plugging your computer directly into your router via an ethernet cable is always the best option.
You can use fast.com or speedtest.net to test your internet connection.
