If you decide to send picture information from your computer to your TV, you need to make sure that the sync is correct. Sync is the number of times that the picture on the screen refreshes. It's different for a computer than it is for your TV. So, if your TV does not have a port or an input that's specific for a computer, then it probably will have a sync issue, which means that when you're trying to look at it on your screen, it will look all jumbled or weird colors or it will scroll rapidly. So, you need to make sure that you have the correct input in order to make it work.
