Borderless design enables immersive and seamless viewing experiences on assembled video wall screens. The 55VM5B ensures clear picture quality even when installed in stacks of more than four. This is very favorable for the quantity of video walls installed in large spaces. LG's LED backlight technology guarantees high uniformity in brightness to ensure a clear picture. On other screens, certain spots may appear darker than others, but the 55VM5B generates high visibility and a consistent brightness across the whole screen. Through video wall image creation technology, color and brightness differences are compensated in circuit part with an algorithm to make the panels into a same characteristic so that each video wall maintains the consistent white balance. LAN daisy chain allows you to execute commands to control and monitor the screens and even update their firmware.
