Installed my HW40 yesterday, coming from a TW9200/TW5030. Mind that what I'm writing here is pure subjective, but maybe it can help with someone needing to decide between both. I loved the Epson for it's picture quality and settings, but hated the noise it made when in high lamp mode and the high input lag. So I sold the whole thing, and got the Sony. Also keep in mind that I have about the worst situation you can use a projector in : light ceilings, bright large windows, shades that do no make the living room dark enough, no way to get a hdmi cable to the projector so need to rely on wireless hdmi and a screen that has been installed here almost 10yrs ago with a too high gain (1.3). Here's what I find after installing the HW40:
+ input lag is near non-existent, fantastic gaming projector
+ the Sony is at least as bright as the Epson, in fact, in a darkened room it seems even brighter
+ the noise this thing makes, or lack thereof, is just bliss. amazingly quiet projector
+ no that it ever bothered me, but SDE is completely non-existent, image is butter smooth. I never took notice of this on the Epson unless I looked for at after reading some complaints. After installing the Sony, the difference is pretty clear.
+ when not using reality creation, the image has a very cinematic look to it. Need to tweak this a bit, when using it image (especially in older movies) seems quite grainy. I'll leave it off for now.
+ fantastic calibrated colours thx to my pro dealer
- damn this thing is heavy, a lot heavier than the Epson (about 2kg more). I'm constantly worried my ceiling mount won't hold
- black levels are definitely a little worse than the Epson, but keep in mind my situation/screen !
- the Epson had less cable clutter, thx to the included wireless. I'm now using Marmitek Gigaview 821 (which works better than the Epson btw, thx to no line of sight requirement), but this adds an extra power supply, hdmi cable etc. Not that clean a view (will post pics later)
- I will miss the auto lens cover
- 3D looks pretty good with the ir glasses, but there seems to be more ghosting than on the Epson and have experienced quite a bit of flicker from the Sony 3D glasses when briefly checking "Frozen 3D" from PS4 yesterday. Need to look into this, possibly setting (tips welcome!)
For me, this was a swap from heaven. The projector is now very quiet, I can game on PS4 without having to put the projector in 'fast' mode and losing image quality, the image is at least as good and even a little better than the Epson (but losing some black level) and the wife finds it a very attractive device. So win for me
Now saving up so we can finally start building an addition to our house, then I'll be able to install a dedicated cinema room (about 3,5m x 4,5m) which will have dark walls and ceiling, lots of pre-installed cables, no more wireless hassle and pitch black possibilities. Not to menion my 'own' dad's room for gaming and movies
