LG UR8000 55" (UHD) vs Roku Plus Series 55"
The Verdict
Both TVs hit the same $399 price point at 55 inches, but they target different priorities. The Roku Plus Series delivers superior picture quality with a QLED panel and 700 nits brightness compared to the LG's IPS LCD at 300 nits, making it noticeably brighter and more vibrant for daytime viewing. Roku's display also supports Dolby Vision and HDR10+, while the LG offers only HDR10. For gaming, the Roku edges ahead with ALLM support and 13ms input lag versus the LG's 15ms, though neither has VRR. The Roku includes Wi-Fi 6 and offers four HDMI ports against the LG's three, providing better connectivity flexibility. Audio specs match at 20W 2.0ch, though the Roku adds Dolby Atmos. The LG counters with webOS 23, which many prefer for interface smoothness, while Roku's platform offers more voice assistant compatibility. The Roku Plus Series is the stronger choice here: its QLED technology, superior brightness, and gaming features justify the slightly different feature set. The LG remains solid for those prioritizing webOS familiarity, but the Roku's display advantage at equal price makes it the better value.
