Plug everything in and turn it on - HD Video Projector Wall

Now it's time to make connections. Note you still haven't permanently mounted anything. You definitely want to make sure everything works before you secure it all in. 

So now's the time to run that extra-long HDMI cable. This is the ideal, over wireless or connecting multiple sources to the projector itself, as it gives you the most flexibility and the highest frame rates and resolutions. It does, however, mean you'll need a receiver or soundbar to connect and switch your sources. A good idea anyway, as you should never rely on the speakers in a projector for sound.

Once it's all connected, check some different content. If you have a 4K projector, make sure you watch some 4K content to make sure your system can handle that resolution. Just because it can handle 1080p doesn't mean it can do 4K.

A geometry test pattern can be a big help.
