Price tag, Sony wins 1999 vs 2999.
So I wouldn't say the Epson 5040 is a better projector than the Sony 45ES, just has different features for different buyers.
Frankly if I was looking for the best 1080P projector for the price, then Sony wins hands down.
If I was looking for the best contrast in a projector then I would pick the JVC RS400 or 500.
To me the Epson is too limited by its weak color performance and brightness. If you want P3 color then your projector is too dim. The projector can go bright but then the color is no longer accurate. The JVC 400 and the Sony 45 are better because of superior technology.
I'm considering all three projectors.
Curious, the 45 does 100% P3 at 1200 lumens?
Someone tested input lag in all color modes on the epson in FINE mode, and I believe some were as low as 23 ms btw. Maybe one mode was 31ms. Then you have the better glass lens, motorized zoom for easy switching from 16:9 to 2.35:1, dynamic iris which some like (including sony 50/55/65 owners), notible detail increase with e-shift, and image enhancement algorithms which professional reviews say trump those of JVC.
I've just about ruled out the JVC because I don't want to game with 240 ms lag, and I figure that unless I coat everything in my room with nonreflective black, the difference won't be that great.
The sony's tempting at $1000 less, but with 4K showing up everywhere nowadays (Xbox one, Scorpio, PSpro, 4k BluRay, Netflix, youtube..) I'm hesitant. I'm tempted to buy the Sony, and then upgrade to a true 4K in a few years, but I tend to keep display technology much longer. I'm just waiting to see how 4k connection issues with the Epson pan out over the next few months.
Don't mean to poop on Sony owners; it's a great 1080P projector for the money, and I'm still considering it. Just expressing my thought process.
