LG UR8000 55" (UHD) vs Vizio V-Series 43"
The Verdict
LG UR8000 offers a substantially larger 55-inch display versus Vizio's 43-inch panel, delivering better picture quality with superior brightness (300 nits vs 250 nits) and IPS LCD technology for wider viewing angles. Both feature 4K resolution and HDR support, though Vizio includes Dolby Vision while LG omits it. Gaming performance is comparable with minimal input lag differences (15ms vs 16ms), though Vizio's ALLM support provides a slight advantage for console players. Audio output favors LG at 20W versus 16W, but neither impresses audiophiles. Connectivity is essentially identical across both models. At $399 versus $199, the LG UR8000 costs double but justifies the premium through its significantly larger screen, brighter panel, and superior overall picture quality. For most living rooms, the size advantage alone makes the LG the stronger choice despite Vizio's lower entry price.
