The LG LM63 is an HD 1080p thus won’t upscale any content to near 4k UHD as its not UHD capable. It will be edgelit covering the very basics on my guide and more akin to a bedroom or kitchen TV.
The Hisense E7hq 43 for not alot more and the 50″ for a little more will leave an HD TV in a cloud of of dust performance wise. For starters its UHD so will upscale the likes of BBC HD content to near 4k. Spec wise its goes much further down my list beinf full array backlit, quantum dot…
UHD 4K first came about in 2001 and have been mainstream TV’s for over a decade now and would see no improvements over your current HD sets.
Given were now talkng about yester year TV’s I cant see the point and would be the point I would bow out!
