Sony VPL-VW1000ES 4K SXRD Projector HT Labs Measures

HT Labs Measures

Full-On/Full-Off Contrast Ratio: 152,000:1

Except as noted, all of the 2D measurements were taken with the projector in the Cinema: Film 1 Calibrated Preset with the lamp control on high, the gamma correction on 2.6, the Advanced Iris set to Auto Full, and the other controls set for the most accurate image within these parameters. There were approximately 160 hours on the projection lamp. The screen was a 118-inch-wide, Stewart Filmscreen StudioTek 130 G3 (gain 1.3).

The full-on/full-off contrast ratio shown above was measured directly off the projection lens using a Minolta T-10 (illuminance) light meter. The 100-percent full-white reading off the screen with the above settings was 21.35 foot-lamberts as taken by our Minolta LS-100 light meter. The black level with the dynamic iris engaged, as seen on this screen, was too low to measure directly by any device available to us. But by using the direct contrast as measured by the T-10 meter, together with the 100-percent white level on the screen as measured by the LS-100, I calculated the full-screen black level to be a remarkable 0.00014 ft-L.

But when any bright object appears on the screen, the black level will increase since the dynamic iris responds to the average picture level. With the Advanced Iris set to off (wide open with no dynamic action) and the gamma correction on 2.2, the full-on/full-off contrast ratio dropped to 2,372:1 (21.35 ft-L full white, 0.009 ft-L full black).

The Color Tracking charts show how well a display adheres to the D65 standard white point at each step in the brightness scale. Note the new form for this chart here, as compared with our earlier reviews. But it conveys the same information. The more tightly matched the three primary colors, the nearer the result is to the D65 standard at each point in the brightness range. The 2D pre-calibration result was excellent and only slightly improved by calibration—though keep in mind that this sample of the projector was pre-production. Post calibration, the result was exceptional, with Delta E values remaining below 1.0 up to 80 percent of peak white, increasing only to 2.17 at 100 percent. (Delta E is a figure of merit indicting how closely the result is to the ideal white point of D65. Below 3 is generally considered visibly indistinguishable from a perfect result.)

The CIE chart shows an acceptably accurate BT.709 (Rec. 709) color gamut, although the brightness of some of the individual colors (not depicted by the chart), particularly cyan and even more so green, was somewhat excessive. While these errors were not correctable as the projector currently lacks a color management system, they will not be visible to most viewers on normal program material.—TJN

Both me and my dealer are confused by this. I need to get this straight because of throw distance restrictions I have. Can you explain this a little more from the middle of page 2 of the article? What does using an anamorphic memory setting have to do with changing the minimum throw distance?

"Sony specifies the throw distance for the VPL-VW1000ES as 1.27 to 2.73; this is said to be reduced to 1.68 to 2.73 if you use the lensless anamorphic memory setting."

Sony sent us a note to clarify and explain this. The company's Rob McDonough responds:

Picture Position Lens memory uses stored lens settings to quickly switch aspects and image sizes, such as between 16:9 and 2.35:1 sources. When calculating Throw Distances, if zoom is going to be used to make these image size changes, there must be sufficient zoom range left to work with. 16:9 images and throw distances must be able to zoom larger for 2.35:1, and 2.35:1 images and throw distances must be able to zoom smaller for 16:9. Thus, there needs to be an extra throw distance limit imposed to keep sufficient zoom range held in reserve.

For 16:9 screen data, the limit must reduce the TD range at the short end, and for 2.35:1 screen data, the limit must reduce the TD range at the long end of the zoom. The attached chart assumes use of a 2.35:1 screen, and therefore calculates sufficient reserve at the long end of the zoom.

The 1.68 limit quoted refers to 16:9 data when zooming larger to achieve 2.35:1, so it applies the limit at the short end. In practice, it usually makes more sense to calculate based on actual screen dimensions, usually the wider aspect, or larger image.

This is a LONG way down the road for the consumer market but I predict that 3D sound will be the next big thing in the industry.

You might be right; see Tom Norton's blog about a new 3D sound system here:

Personally, I expect 4k to be realized far sooner than most people currently suggest, even with the sluggish/bearish economy's dilatory effect on home media upgrades. TV's (recent at least) traditionally used 3 ~light cells (RGB) for each pixel (1920x1080 pixels); however, recent development of color filters allow for the transition to one of those light cells, effectively tripling the resolution available via tv technology already mass-produced. That means very little needs be engineered/accomplished to see 4k screens marketed at today's prices. Recording devices increasingly trend towards a more reasonable 4k price point, and the second projector is now available at 25k, down from 125k....I'm betting 3 years on the topside.

Nowadays technology is running as faster then wind. As a result electronic companies can invent some wonderful creation for us. In this post I've come to know about the Sony VPL-VW1000ES 4K SXRD Projector Settings. It is really a well invention. Thanks!!!

3D sound integrated into all home theaters, I believe is on the way. We shall see when it arrives at the right price point. Just like with anything else technology related, there will be a tipping point @ a specific price. Just look at Home Automation costs in 2013, they are definitely becoming much more competitive..Home Automation is soon to be a baseline for homes over 300k.
