Samsung LCD TVs have no burn-ins unlike plasma televisions, which, when used for quite a while has an image imprinted on the screen. With this in consideration, you can use your LCD TV and connect it to your PC or play video games with it minus the worry of burn-ins.
If you want to use your LCD television as a computer screen, better buy an LCD monitor. Otherwise, you will be paying for many other things like a tuner, audio-visual inputs, and other things that you do not actually need. Now if you are a video game fanatic, having a 30-inch screen for your gaming purposes is something that is definitely worth showing off.
First of all, make sure that you have the right kind of television to use as a monitor. The next thing that you should check is if your LCD TV has a VGA option or if it supports connection to a computer or gaming console. If there is none, that can be very frustrating.
Your computer must be near your television for easy access. Just imagine if your LCD TV and your computer far apart. It will really be a hassle and that is not reasonable. So when you say that you plan to use your LCD TV as a computer monitor, place them near each other.
Have the necessary wires on hand to make the switch between LCD TV and computer easier. Set up the wires that are needed for the connection so that when you decide that you want to switch, it will be easier and convenient on your part. You can also set up a device where the change will be a lot easier.
If this is what you really want then learning to utilize your LCD TV as a video monitor is very important. The pictures are crystal clear and your eyes will not get tired and you do not have to squint like you usually do in CRT monitors. The good thing about this is that you have a double use to your LCD television.
