Our Verdict
Samsung RU8000
LG CX OLED
The LG CX OLED is a much better TV than the Samsung RU8000. The LG is an OLED TV, so it's able to produce perfect blacks. The LG also has a significantly faster response time, wider viewing angles, and its out-of-the-box color accuracy is much better. In addition to its FreeSync support, the LG is compatible with NVIDIA's G-SYNC to reduce screen tearing when gaming. The main downside with the LG is that it's susceptible to permanent burn-in, which the Samsung is immune to. That said, burn-in shouldn't be an issue if you watch varied content.
