Home projector parameter selection
Generally speaking, projectors cannot be directly connected to cable TV for viewing. If you have a medium, such as a computer, install a TV card on the computer and let a limited TV play on the computer, you can directly connect the projector with the computer. Accurately speaking, the projector is just a display tool, because there is no cable TV interface, you can borrow something else to turn it around. As for your living room is only 4.5 meters and your TV wall is 3 meters, I suggest you choose 100 inch curtains. If the budget is not much, buy a brand, low-end machine. It is best not to consider domestic machines. At present, the price of low-end brand machines is also very high, so you should pay more attention to the resolution at home.
