The Home Cinema 3700 is one of three projectors launched in September 2016, replacing the older 3000 series. There are significant improvements. Because it has what I felt was the best feature set and value proposition, we decided to review this one. I'll mention below, the differences between models - some noticeable differences, and point out what types of viewers might prefer each model. All have HDMI with MHL to support streaming sticks and other MHL compatible All of these Epson's have two years parts and labor, and have a free (freight) rapid replacement program instead of repairing warranty failures.
The HC3700 - aka Home Cinema 3700 - is the middle priced model with a list price of $1499. It claims a healthy 3000 lumens, internal speakers and improved contrast relative to its predecessor. And, it has a healthy amount of vertical and horizontal lens shift, something not common on sub $2000 projectors (although a number of projectors in this range have a small amount of lens shift.) All three models are 1080p projectors.
For $200 less is the HC3100. 2600 lumens (making the HC3700 15% brighter, not huge but a respectable bump.)
