Our Verdict
LG UQ8000
Samsung CU8000
The LG UQ8000 and Samsung CU8000 are decent TVs with different panel types. The LG uses an IPS panel with wide viewing angles, while the Samsung has a VA panel with better contrast. The CU8000 has a wider color gamut, but the UQ8000 has a better HDR Native Gradient and much better color accuracy. The LG also uses a traditional RGB subpixel layout (except for on its 50 and 70-inch models), making it better suited as a PC monitor.
