If you want to use your TV as an entertainment center in a new way, or if you want to watch multimedia on a screen that’s larger than what your TV can provide, connecting the device to a projector is the simplest solution.
In this article, we’ll help you connect your TV to a projector with HDMI and also explore how using Chromecast and other USB devices can make this process even easier.
Before we jump into the details, let us clear some basic theory and see if the TV and projector are ready to be set up with each other.
Does your Projector have HDMI?
The first thing you can do is check if your projector has HDMI ports. If you find out, make sure the projector has HDMI 2.0(or above). [HDMI 1.4 is a widespread standard, but not as fast as HDMI 2.0 and higher.]
Does your TV have HDMI?
The second thing to check if your TV has an HDMI port and so on. Check if the type of cable is right. For example, some TVs support higher-resolution video output out of the box; while some models need a converter to work properly with an HDMI cable (most converters are available at any electronic store).
How to connect tv to the projector with HDMI
If you have a 1080p or higher TV, then you will be able to connect it to a projector and watch your favorite movies, play video games or browse the Internet. The easiest way is to use an HDMI cable with most new TVs.
HDMI is the universal digital connection for up to 1080p resolution. Connect the HDMI cable from your TV’s digital port or “DVI” port (if your TV has one) to the HDMI input on your projector. The two devices are now connected and you can watch any multimedia on a screen larger than what your TV can provide.
Here are the step-by-step instructions for HDMI-based connection:
- Step 1: Check the back of your TV to locate the HDMI ports. It should be labeled clearly. Make sure your HDMI cable is connected to the TV and projector.
- Step 2: On a projector, locate the HDMI input port and connect the device’s output to your projector (the input of your TV). On a TV, it should have an HDMI port on the back, near other connectors for video and audio. If you’re not sure what you’re looking for, read through our article on setting up a home theater system and find out which inputs your equipment has.
- Step 3: Connect your other devices to the projector – speakers, Blu-ray player, video game console or have those computers ready to play movies/games.
- Step 4: Turn on all the devices and enjoy a big screen!
How to connect tv to the projector without HDMI
I know you want to avoid HDMI cables if you can. I really respect that! So how do we connect our TV to a projector without HDMI?
This is where Chromecast enters the picture. Chromecast ditches the usual cumbersome HDMI cable in favor of a simple USB cord that plugs into an outlet in your entertainment center.
Once plugged in, the dongle can stream audio/video from your smartphone or tablet via Wi-Fi for use as a screen for your TV. There’s a lot to explore in this post but let us start with some simple steps:
- Step 1: Connect the Google Chromecast™ device to your TV’s USB port using the USB power/charging cable provided (included inbox).
- Step 2: Plug the HDMI output of your TV into the HDMI input of your projector.
- Step 3: Connect Chromecast™ to an AC outlet or extension cord using the USB power cable provided (included in box) and power on the device.
- Step 4: Load your content from a compatible app(Netflix, YouTube, Hulu, etc). Then use your phone, tablet, or laptop as a remote and navigate through your content.
That’s it! You are now ready with a big screen entertainment center. You could also pull out an old computer that is running Windows XP/Vista/7/8/10 and connect that computer to a projector.
Different Types of Projector Connection to Connect TVs
There is a lot of projector connection available to set up a projector to watch tv. I will introduce five types of projector connections, one by one.
RS232 Y/A Video Connection (CVBS)
This is the oldest technology ever that was used to connect a projector and TV. It may not be feasible for some projectors with HDMI or DVI because it only can support up to 480i resolution and such a resolution is no longer needed.
This technology still works on some projectors without HDMI or DVI ports but with older legacy components.
HDMI Digital Connection
The HDMI digital connection uses an HDMI cable to connect your TV and projector. The HDMI cable must be connected in order for you to view multimedia on the larger screen of your TV with your projector.
HDMI 2.0 and HDCP 2.2
HDMI 2.0 is the latest HDMI version, which can support 4K resolution on a big screen. It also supports HDCP 2.2, which is the latest copy protection standard for content providers such as Netflix and Amazon Video.
DisplayPort Digital Connection
DisplayPort is another digital connection that offers high performance to connect your TV and projector (or computer). It’s available on both Windows PC and Mac PCs, at least the newer ones.
DVI-D/VGA Analog Connection
This connection type uses either an analog VGA or DVI-D cable to connect your TV to your projector. It is the slowest connection type that supports the lower resolution, which is not ideal for large screen sizes.
Which Connection is popular to hook Tvs to the projector
HDMI and DisplayPort connections are popular to connect TVs to the projector. HDMI is cheaper and has a longer cable than DisplayPort.
The above is the general process and information to hook up a projector to watch TV. However, there are still some tips that you can try out:
If your set up your TV on the floor, use adequate extension cables with a longer length than usual extension cables for your TV. The added length provides more room for you to place your cup and other things in front of the screen.
Make sure that you put your AV amplifier at least 40-50 ft away from the viewer’s seat so that it won’t be easily affected by the noise of the projector. Projectors generally generate a lot of heat and can be warm when using for long time hours.
