Linux Lite Forums

I went to vsynctester.com, the screen tearing never stops even though I installed third-party software for graphics and Wi-Fi hardware and additional media formats during Linux Lite installation! I am using integrated graphics/Intel graphics/onboard?
My pc model: PRO904059
My motherboard: NUC7i5DNB?

How do you exactly use this? I heard that Linux Lite is a lightweight Linux distribution that runs on the standard Linux kernel but is based on Debian and Ubuntu. It features a modified Xfce desktop environment. It has great specs but I just don't have an idea how I can benefit from installing it.
