A:AnswerThe LG 4K UHD HDR Smart LED TV - 55" Class (54.6" Diag), Model # 55UJ7700 is a VESA Compliant TV that has an A x B VESA Wall Mount Pattern of 300 x 300 (mm). The metric measurement for the width of the screws that will fit into the wall mount bolt holes is M6 (i.e 6 mm). The length will depend on the depth of your current Wall Mount. If you still have the screws for it and if they have the same width and your Wall Mount supports this TV's Wall Mount Pattern, you can look try the screws to determine if they are the right length or not. Your Wall Mount should have come with other screws of varying lengths and spacers...^IFV
A:AnswerYou can rent movies through Google Movies, Amazon Prime Video, Redbox, Fandango and probably some other apps that can be downloaded through the LG App Store. No other boxes or sticks required.
A:AnswerWe purchased a universal TV stand that hangs from the ceiling that works really well. You can also use a universal wall mount. Or one that is attached to a base unit. Photo shows our configuration.

A:AnswerThis TV can be mounted using a Vesa pattern: 300 x 300. When you do not use LG’s wall mount bracket, use a wall mount bracket where the device is adequately secured to the wall with enough space to allow connectivity to external devices. If you are using a non-adjustable mount, attach the mount to the wall. Attach the cables to the TV first, then attach the TV to the mount. ^CP
A:AnswerDepends on what you're looking for in a TV. The new 6300/7000 line up from LG right now are great for gaming with low input latency compared to Samsung's model and good overall picture quality (you must turn off automatic energy saving otherwise the screen is a bit dim). If gaming is not a factor in your purchase, Samsung has a bit of an edge in picture quality for a slightly higher price with better black display.
If budget is not an issue, check out LG's OLED TVs. They are quite superior all around to Samsung's current line up of televisions, including gaming.
