20 by 19 foot upstairs gameroom. Light control not ideal with wall of windows on one side and rear opening to staircase. Nighttime viewing only. these shots taken at 8:30am dec 7th. Pic quality with BR sources is STUNNING!! One can really see the dropoff to Directv HD source- compression artifacting and noticebly softer image. Couch sits 15 feet from screen. I love this setup. Wow factor cannot be underestimated. Lack of eyestrain an unforeseen bonus. Fills your vision when watching like no TV can.
