V29 - WD52627, WD62627
V30 - WD52628, WD62628, WD62827, WD73727, WD73827
V31 - WD62927, WD73927
All models provide HDTV OTA/cable tuners with cable card. 827 and 927 series include hard drive for DVR functions with two tuners. You can play and record plus you can record and watch another channel. All provide a 1394 connection and indeed the model that was inspected had a small box with HDD attached. The full capabilities of this are yet to be known or pricing and options. I was told this particular one was 40GB and should retail for about $120.
All models include Net Command and TV Guide
All models use the HD4 960X1080 wobulated DLP chip.
Display tested was the WD52627 using test patterns from a VP403 pattern generator via component only at 16:9 only.
While the WD52627 does not come with a screen protector, Diamond Shield, it is optional as an accessory. Some of the other models include it and it is also optional.
With 1080I the 1920 response was blanked out light gray and the 960 response had phase/frequency artifacts. With 720P I was greeted with a perfect even line response to my surprise although the 1280 was still visible it was also significantly down in level showing a very dark gray and black response. The display supports HDMI only and a DVI to HDMI adapter was not available. Only the V30 and V31 provide a direct bypass for 1080P sources via HDMI but I was unable to verify this.
Tracking and color temp were off as expected with low clearly having a blue tinted 100IRE window.
Numerous scaling artifacts were present. While I am not familiar with the source the artifacts that were seen seemed directly related to what was observed with full field white patterns at various IRE levels and the ramp pattern. Red push as expected but controllable using Perfect Color to turn down the red saturation. Perfect Color is imperfect as it does not allow you to adjust the phase of the secondaries, only saturation, which is not a part of any proper color decoding circuit for secondaries. Color decoder saturation only applies to the primaries, RGB.
The display also offers two responses called high bright and natural bright with high bright calibrated for sales floor presentation to compete with other brands and their saleable artifacts.
Dark Detailer is an iris like device that dynamically reduces light output directly from the lamp based on picture content. Indeed this display had a tolerable black level with lights turned off using a 10IRE window! While this greatly improves black and white contrast ratios the effects on imaging when using a dynamic iris have yet to be fully fleshed out but is similar to ABL, automatic brightness limiter, used for CRT and plasma which causes the black level to change and therefore the interfield contrast as well; A fancy way of saying your blacks will not be as black with bright scenes as it was with dark scenes. Indeed with a 100IRE window the black level increased substantially. Depending on the image this increases perceived dynamic range or can reduce it. We would prefer an adjustable fixed range or simple on/off to control light output so we can set it to match the viewing environment or create day night settings. This is similar to the back light control highly recommended on LCD flat panel.
Edge Enchancement was awful producing obvious 2 pixel black or white lines on edges where they do not exist. This is caused by SharpEdge which is not an option on the V29 but is available on the V30 and V31. Unable to confirm if this completely removes the artifact.
The V29 and V30 (except the 73" model) use 120W lamps rated for 7000HR and all the rest use 150W lamps rated for 3500HR. If you are seeking a dark room application the 62" with the 120W lamp will help you get blacker blacks.
The color wheel speed has been increased but the segments have been reduced from 7 to 6 all to reduce the rainbow effect. That said I could clearly see this artifact. Is it improved? Hard to say.
The controls for an ISF calibration were minimized to RGB cuts and drives only. As a new display the community has not had a chance to investigate what possibilities exist. This will be updated as the info comes to light.
Optical cleaning is made easy by simply removing the mirror assembly from the back held in place by a multitude of screws.
It is difficult to make a recommendation at this time for videophiles and critical viewing applications since this is new product and has not been fully tested. If indeed the V30 and V31 allows direct bypass, a pixel for pixel response, no edge or detail enhancement and a decent gamma response this display could be considered for videophile applications. Due to the color decoder issue this will probably not be practical for critical viewing applications and even some videophiles will not accept that kind of error when there are other displays that truly have perfect color because it has been set correctly by the manufacturer or the necessary controls are available in the customer or service menu.
