Our Verdict
Samsung Q900TS 8k QLED
LG GX OLED
The Samsung Q900TS 8k QLED and the LG GX OLED are very different TVs with different panels and resolutions, each with its own advantages and disadvantages. The LG can produce perfect blacks by turning pixels off individually, making it ideal for dark room viewing. It also has a near-instantaneous response time, making motion look clear. However, it doesn't get very bright, so the Samsung may be better for well-lit environments. While the LG can't support an 8k signal like the Samsung, there's still very little native 8k content, so its value is arguable given the performance advantages of the OLED.
