Our Verdict
LG NANO99 8k 2020
LG GX OLED
The LG GX OLED is significantly better than the LG NANO99 8k 2020. The GX has an OLED panel that can individually turn off pixels and it produces perfect blacks. It also has much wider viewing angles, better reflection handling, a near-instant response time, and gaming features like VRR support. However, the NANO99 displays 8k content, gets slightly brighter, and doesn't have the risk of permanent burn-in associated with OLEDs.
