I received the W1080st and I tested it... is a good VPR!! At the moment i'm happy with it. My vote is 7,5 / 10.
I replaced the Optoma GT720.. these are my considerations:
- Black level and dark shadows are very good. Not excellent like an High Contrast VPR of +3000$ but very good. The optoma GT720 have an orrible black level, now I'm finally happy with the benq.
- PIxeling / screen door effect is still present (140" of screen from 2-3 m) but very less noticeable! As expected.... it's not a miracle (like could be a 4K VPR) but overall i'm satisfacted.
- The lens is very good and is "inside the box line" of the VPR. I could mount a ND2 filter without problem... fantastic!
- The zoom is very useful.. I use it just a little bit to compensate the distance from the screen.
- I don't have brightness problems
- Actually I have just to solve a little focus problem at the center of the screen. But I'm sure at 75% that the problem is just the position... with the short throw VPR is very diffucoult (sometime almost impossible) find the perfect position!! just 1° change everything!! However also with the actual focus for me could be ok!
- the VPR is more silent of the optoma
- the "out of the box" settings are really good
- the remote control has no backlight or led... and is very cheap. however for my use is perfect (the important thing for me is the 3D Invert button!!)
- I'm using it with the PC without any problem with HDMI connection (ATI 6850)
- The 3D is great.. but work in a different way respect the Optoma. With the desktop mode I can't use the 120hz refresh rate. just 60hz. But with the Tridef 3D player is all fine. So if the VPR don't recognize a 3D signal reject the 120hz. I will make more tests and I will try to modify the EDID.
- I confirm that this VPR require 144hz glasses for the 3D. The 120hz glasses doesn't work also with the PC input
- Finally I can work with the FULL hd resolution!! Another planet for the PC use.
At the moment i'm happy... The first impression was not so amazing, but after the initial setup I can say that is much more better than the Optoma! My next VPR will be 4K...
