Is there banding on the LG C8 OLED?
The LG OLED C8 displays our test gradient smoothly with no significant banding. In certain scenes there is some banding noticeable in large areas of similar color. This can be reduced by enabling ‘MPEG Noise Reduction’, which toggles the gradient smoothing feature of the C8.
What is the design of the LG C8?
The design of the LG 2018 C8 is excellent. The stand is wide but very sturdy and well built. The frame around the screen and stand are made of aluminum and seem well built. The stand is designed to help direct sound throughout the room, but due to its shape, it is not possible to place a soundbar directly in front of the TV.
Where are the HDMI inputs on the LG c8pua?
The rear of the LG C8PUA is very similar to the C7. Basic cable management, only a small removable cable guide as seen here. The 4 HDMI inputs face to the side, but the composite input is rear facing and may be difficult to access if the TV is wall mounted. The controls are located on the back to the side, similar to the C7.
Is the LG c8p a 1080p screen?
Also, the LG C8P supports a 1080p @ 120Hz input for those who want the most fluid experience. Motion handling is excellent, due to the instantaneous response time. Unfortunately the brightness of the screen changes depending on the content and areas of static content may have a risk of burn-in ( see here)
