Can it be used to watch cable television? Is there a way to hook up video games on this? Can I also watch Netflix?

Since this is a screen (a medium to use as a surface to project), it can show anything that comes out a projector, including movies, news, videogames or even laser shows. It is the projector’s technical characteristics and connectivity that determine what it can be hooked up to (TV, laptop, tablet, smart phone, iPad, cable, satellite, DVD, etc.) The screen itself doesn’t connect to anything.
Since this a HD screen (ratio 16:9) we recommend a HD projector or a full HD projector. If you need assistance in choosing the right one please ask.
