Just received my new HD131Xe. It's replacing an Epson EX70 (720p WXGA), which has served very well for five years. The EX70 will be doing family room service, while the HD131Xe takes over the home theater projection duties.
One of the reasons I picked the HD131Xe was the throw ratio put it right in the mid range for our existing celing mount distance (13') and screen size (111"). Several competing projectors would have required moving the mount, patching drywall and repainting; I would have done that if there was a more compelling product than the Optoma, but I didn't find anything that offered better performance and value.
I ran through the set up last night. I must be living right, because my mount height and screen height were perfect. I didn't have to touch the keystone settings. I have it set on economy brightness, which is plenty bright for our light controlled theater. I played around with the color settings and modes; mostly leaving the default settings. I'll tweak as I get more experience with input from various sources. Really impressed with the picture quality. Noticeable step up from the 720p I am used to. Haven't noticed any rainbow effect, don't know if I or anyone in my family is sensitive to it. It's also quieter than the Epson, which I also used in economy mode. Really impressed with what you get for a $700 projector. Looking forward to trying out the 3D, as soon as I get some glasses.
It was hard for me to move away from Epson and LCD technology, because we've enjoyed the EX70 so much. But, in the same price range, Epson doesn't have a compelling 1080p 3D solution. Takes a bit more money to get to the same point with Epson's offerings.
For those of you looking for a good deal on the HD131Xe: I'm an Amazon prime member, and that's where a lot of my electronics purchases come from. In this case, I ordered from Rakuten.com. Pricing was equal to Amazon, but no tax, and I was able to use their super points promotion code to get the equivalent of a $100 credit that will become valid in a couple of weeks. Will use that to buy a few pairs of 3D glasses.
