so im looking for an external monitor for my mac book pro. preferably in the 25-30'' range. also i want to be-able to hook it up to a blue-ray, cable-tv, and gaming systems; but its main use will be for film editing as im just starting film school. what are some good options that are not going to kill my back account? im thinking that i will probably have to get a TV monitor rather then a dedicated computer monitor.
