Purchased a used LG 32LD550, 1080p 32" using it as a monitor via HDMI. Much better than my last cheap vizio. But, the LG has input lag where the cheap VIzio didn't somehow. I got to down to barely noticeable though by turning some things off and using game mode but it's still there just barely. I could probably just get used to it but wondering if there are any more options? Also wondering about calibration or something to get the coloring perfect..
