You could build a budget-friendly 97 inch diagonal custom home theater around a 16:9 HD format front projection screen with a viewable screen area measuring 84.54 inches wide x 47.56 inches high onto your flat wall using the Screen Goo digital grey projection screen paint kit. You could go with Mitsubishi's entry-level 1080p DLP projector and Sony's versatile PlayStation 3, which not only does 1080p video gaming, but also plays Blu-ray and DVD movies, music CDs, and can even stream movies from Netflix! You'll also need to connect a separate audio system, perhaps a Onkyo THX certified home theater receiver and a Klipsch surround sound speaker system.

PS3 and any other video game consoles, as well as HDTV tuners/DVRs should be connected to the A/V receiver using a single HDMI cable, and a single (long) HDMI cable can go out to the projector. Because everyone's components and situation are different, additional equipment (mounts/racks), cables (HDMI, digital audio, component video, Ethernet), speaker wire, accessories, installation tools, and expertise may be necessary or desirable to complete setup of your 97 iNCH home theater!
