As a general rule, it's risky to buy TVs for gaming devices because a large percentage of them have noticeable input lag from 0.1 seconds to 0.5 seconds.
Also, a TV as a monitor will have low pixel density. So games will not look as sharp as a 24" would display them as, and text will be much larger, which might very well result in it being hard to read for some. Depending on distance of course.
