There is not going to any difference from a monitor & tv of the same size at the same distance on the eye's. The only difference is computer monitor may (depending on model) have a higher resolution, like 1800 or 2200. The best thing is to calibrate the tv to the rooms lighting conditions.
I do not know what the people are telling you about a film on the screen to protect your eye's? No monitors screen will protect your eye's any different then a tv, unless it has a filter (after market) to bring down the contrast, like tinting windows, so the screen is not so bright & you do not get eye strain... The fix turn down the contrast on the monitor or tv, if needed add backlighting.
The tv will have more options then a computer monitor for PQ.
I have to Buy a new Tv or Monitor to use to plug My Notebook, My Xbox 360 and My PS3 and all that things it's in my bedroom, so I don't have much space (Note: I`m going to buy a Full HD TV or Monitor). So I Have to buy a Tv or Monitor from 22" to 32".
What I really want to know is if a TV really is bad for the eyes, because I`m going to use as a monitor (So I'm going to use close to that) but it`s nice to have 1 HDMI connection left. And people keep saying that Tvs is bad for eyes because Tv is to watch in a good distance from it and because of that, there is monitors who has a film in front to protect the eyes.
