You could build a 98 inch diagonal custom home theater around a 16:9 HD format front projection screen with a viewable screen area measuring 85.41 inches wide x 48.05 inches high onto your flat wall using the Screen Goo digital grey projection screen paint kit. You could go with a Panasonic 1080p LCD projector and their versatile, space-saving Blu-ray/ DVD/ Compact Disc/ VHS combo player. You will also need to connect a separate audio system, perhaps a Denon home theater receiver with Definitive Technology on-wall mountable surround sound speaker system.

Video game consoles, HD TV tuners, and/or 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 room and situation is different, additional equipment (mounts/racks), A/V cables (HDMI, digital audio, component video), speaker cables, accessories, tools, and expertise may be necessary or desirable to completely set up your 98 iNCH home theater!
