    Learn more about Projectors

    The television screen seems to be getting larger and larger. These days you can easily find a high quality and reasonably priced 65-inch TV, and some of the best TVs you can buy are also quite reasonably priced. But, if you want a true cinematic experience, a projector is the way to go. Projector screens easily reach 120+ inches, and some projectors now support 4K UHD resolution and cover impressively wide color gamuts, just like their 4K TV counterparts. In a true home theater the difference between a large screen TV and a projector are simply a different experience all together and the projector becomes the thing that makes that impression last.

    We also install TV's and Projectors in conference rooms. There are solid arguments for both appliances to be used in different scenarios. Often times this decision can be made simply by the size of the room or if the business wants a whiteboard functionality etc. We often prefer Large Format TV's or Touch Screen TV's for conference rooms.

    So should you buy a projector? Well, projectors are a bit more complicated than TVs and require a little extra work and consideration, but the best projectors will bring your home theater to life. There are major factors that will determine whether a projector is right for you.

      Can you control the light in the room?
        While many projectors have much brighter lumens than previous models. You still have to have the ability to control your lighting as well as block light from outside.
      Is there space in your area for a screen?
        You are going to need both the space to install a screen and the depth to have the projector far enough away from the screen to project on your screen. First you can mount a manual or motorized drop-down screen from your ceiling. You could also mount a fixed screen to your wall, so long as you're willing to sacrifice the space. You could also paint your wall with a special projection-screen paint.
      Do you have an A/V receiver?
        A good A/V receiver is an important part of any home theater, and because projectors often have fewer connection ports than TVs, they are perfect for projector setups. If you plan to connect just a single device to your projector and have a sound system you can connect to it, be that a Blu-ray player or game console, then you don't necessarily need any additional equipment. But since most projectors have only one HDMI input, you'll need an A/V receiver to connect multiple devices. An HDMI switcher is also an option, but an A/V receiver is better: it will also provide sound to your speaker system you definitely want a sound system, projectors have very weak speakers, if they have them at all.


      If you've gone through this guide and still aren't sure if a projector is right for you, please call us and we can help you decide without any pressure.
