My own experience in this direction is with televisions which were already set up for computer connection (i.e. had VGA inputs) and even then the results were not brilliant: for example with a standard definition (1024 x 768) widescreen TV the pixels were too wide and everything appears too fat; on another TV, this time high definition, despite the dedicated inputs and using the settings in the TV manual the computer screen flickered and was essentially unusable. In the end I gave up and bought a 22inch monitor (which is absolutely fantastic)
