To answer this question, shoppers need to know the naming system that LG uses for each year's offerings. A list of bullet points is a good format to illustrate this naming scheme. Take the 55-inch model of the UQ8000 series, which has the code 55UQ8000:• 55 denotes the screen size• U describes the panel type, which is a UHD panel in this scenario• Q indicates the year that the product line came out; which is 2022 for the UQ8000. This means that the UP series came out in 2021 and the UR series launched in early 2023.• The next four numbers describe the market segment of a particular product line. In our example, the 8000 indicates an entry-level series of UHD televisions. 9000 would indicate a mid-range or high-end product lineIn summary, the UP series is the 2021 lineup of UHD TVs from LG. This positions LG’s UP8000 series as the predecessor of the UQ8000 from 2022. It then follows that the UR8000 is the company's 2023 product line of entry-level UHD TVs. Shoppers should also note that there are additional differences between the UP and UQ series.
