sure! These days there are many tvs with high resolution screens that can display clear and crisp pictures unlike old crt monitors with their heavy lead lines that could damage your eyes upon prolonged usages. In order not to cause extra strain on the equipment caused by making the image larger than what the monitor can handle additional power draw by the lcd is needed and therefore cheaper power supplies are used inside tv sets that are less efficient to power compared to pc supplies of the same size rating which use more power efficient transformers to run off the mains for lengthy periods where as televisions may need to run from batteries if they are going to be used as desktop or laptop substitutes for long periods of time without mains supply and also so that they do not have to drawn too much from the main power supply due to the need for more amperage of current needed to drive the hd lcd panels at higher resolutions and higher refresh rates from today’s movies etc.
