I just purchased this projector on the strength of Art’s review. I got it set up on Wednesday and have watched a few movie scenes and a couple of episodes of Person of interest. I’ve just read this thread through from start to finish and there are a few recurring themes/questions. I’ll try and deal with them one by one:
Picture adjustment menus remain open if you access them through the setup menu and do take up a bit of screen space. You can however adjust basic picture settings such as brightness and contrast using the direct button on the remote and this only displays a slider bar towards the bottom of the screen.
: Video controls such as tint are greyed out when using digital signals. This is how it should be as “Tint Control” is only relevant to analogue NTSC signals which are susceptible to having the colour information slightly out of phase with the remaining picture information thus producing incorrect colours that are particularly noticeable with skin tones. In the digital world this is not possible and any issues with skin tone are due to other issues which need to be addressed in other ways. The W1070 has excellent calibration controls in order to do this.
3.Colour Wheel Speed Consistency
: Unlike the W7000 I believe the W1070 remains at 6x speed continuously. I tried switching between low power Cinema mode and high power Dynamic mode and there was no audible difference from the colour wheel. Also, the W1070 takes a split second or so to syncronise with a new colour wheel speed (changing from 50hz to 60hz or 24hz) and displays flickering while this occurs. I believe that if it was changing from 6x to 4x it would not only be audible but visible as well. I neither see nor hear any sign of this.
4.Colour Wheel Speed
- NTSC is 60hz (60 times per second) = 3600 times per minute
- 1X wheel speed = 3600 rpm
- 2x wheel speed = 7200 rpm
- 3 x wheel speed = 10800 rpm
There is nothing faster. To get multiples of these manufacturers add second colour elements to the wheel so the wheel is rgbrgb thus doubling the effective rate. This is how it’s always been done and as such it is a “true 6x” wheel.
- Diameter of Outside of plastic housing = 45mm
- Diameter of Inner section of lens including black plastic ring = 38mm
- Diameter of actual glass = 33mm
Sorry. Never fitted an ND filter so don’t know which measurement you need.
: Coincidentally I’ve just replaced my Marantz VP4001 with this projector. Unfortunately the reason I replaced it was because mine stopped working so any comparison is from memory rather than a true A/B comparison. The projectors are very similar in that they are extremely sharp and very bright (VP4001 was one of the brightest home cinema projectors when calibrated). I’m sure the lens of the VP4001 was superior but the W1070 can resolve a 1080P 1:1 test pattern virtually perfectly and doesn’t suffer from much chromatic aberration at all. Certainly nothing visible from a normal seating position. The W1070 displays far more detail than the 4001. Textures on peoples clothing are clearly evident. Skin tones seem more natural and I’m pretty sure there’s more shadow detail but without doing a proper A/B I wouldn’t bet my house on it. If you like your VP4001 I’m sure you’ll like the W1070. Is it worth an upgrade? I’m not going to make that decision for you I’m afraid.
. Pretty bad and off horizontally to the left if you have the PJ ceiling mounted. It comes out at roughly 45 degrees so will more than likely be on visible on your side wall.
: My firmware is 1.02 and I have not detected any flickering.
Hope this was of assistance. Any further questions I’ll be happy to answer (so long as it doesn’t relate to 3D, computers or gaming). I’ll try and work up a bit of a review over the next few days but I really need to watch it some more first.
