There's an old Rule-of-Thumb in the A/V World that you want to sit ~4x away in inches the diagonal size of the Video Screen. This has changed over time to more like ~3x that ratio in inches. So, for an imaginary 40" Screen you'd want to sit either 160" away or ~120" away. The thinking is that you don't want your Eyes 'racing' all over the Screen from being 'too close', but you still want to absorb all the action.
If one sprung for a high end Laptop [my preference] with a 15" Screen, you could sit ~45" away and still absorb all the Movie or Video action. No pricey TV Mount needed. Some folks are buying large, >Terabyte Drive Laptops and putting all their Music and Video on those. They also come with TV Tuner 'Cards' to serve as a high end Digital TV/Audio Source as well.
