No ...that just means that the resolution is the same as a TV with full HD capability. The reason why computer screens often feature higher resolutions at smaller screen sizes is simple - you sit a lot closer to the computer screen.
The computer screens are just like TVs - some of them have a great picture, fantastic uniformity and breathtaking contrasts - while an even larger lot just displays pictures in a less spectacular manner. The great performers are often the more expensive ones, while the so called bargain screens might not end up delivering all that you hoped for.
You can play Blu Ray on a monitor, but the monitor has to support HDCP (High Bandwidth Content Protection) to show all the content.
The only thing I do not understand exactly is - why?
