Great TV to use as a PC monitor. The SJ9500 supports all the essential resolutions, including Chroma 4:4:4, but it's also one of the rare TVs to also support a 1080p@120hz input. Combined with a very low input lag and low motion blur, it makes for a very suitable monitor. Some users, however, might find horizontally alternating stripes of the screen to be a little distracting.
