Yes, assuming your LG TV can play a 1080p .mkv movie.

Transcoding means decompressing the original video, optionally converting it somehow, then recompressing it. For instance, if you needed to convert your 1080p mkv to a 720p format for your tablet, then the NAS would need to decompress the video (to get the 1080p picture sequence), rescale each picture to 720p, and then recompress it.

Or if your mkv has a 40 mbit video rate, but you need to reduce the bit rate because your WiFi can't carry that much. In that case, you also need to decompress the video, then recompress it at a lower rate (and lower quality). You don't need to rescale the pictures, but the hard part is the compressing/decompressing.

The RN100 series doesn't have the horsepower needed for that kind of stuff. But if the video is already in a format that the receiving device can play, then transcoding is not needed.
