Off topic question about recording..

Before anyone says it, I know this is probably the wrong place to ask this, but I thought I'd give it a try since most people on the Premiere forum know about video production and whatnot. So basically I've got a three monitor set up for gaming and recording for YouTube. However, I use a TV screen instead of an actual "computer monitor". The resolution of the monitor I record is 1920x1080 (1080p), yet my recordings are noticeably blurred. Not a great extent of blurriness, but noticeable. I was wondering if someone can tell me if using a TV screen as a monitor instead of an actual computer monitor can affect recording quality? Thanks to anyone who has an answer!
