Product Review (August 2003) - InFocus
ScreenPlay 7200 High-Definition DLP™ Projector

The latest Digital Light Processing™ (DLP) home theater projectors have come a long way from previous generation models. The ScreenPlay 7200 from InFocus Corporation uses the latest HD2/Mustang Digital Micromirror Device™ (DMD™) from Texas Instruments for a stunning high definition image. The new HD2 DLP has an increased deflection angle of 12° versus 10° (used in the earlier HD1 DLP) and a Dark Metal process used on the individual mirror surfaces further improves image contrast. The native resolution of the HD2 DLP is the same 1280x720 pixel array used in the earlier HD1 DLP. Complimenting the new DLP technology used on the ScreenPlay 7200 is Faroudja's highly regarded video deinterlacing and scaling processing.

The ScreenPlay 7200 is medium sized projector (measuring about 13" wide by 9" deep) with all the attributes of a great home theater projector. However, the look better resembles a portable projector with a large molded handle on the front housing. We certainly have no objections to this since the handle proved to be convenient during our installation. Further evidence of this projector being used in portable applications is the full set of user controls on the top of the chassis.

Light from the ScreenPlay 7200 projector is produced from a 200/250-Watt UHP lamp. The precision lens optics is designed by the optics experts at Carl Zeiss as noted on the lens housing. Single DLP projectors require an internal color filter wheel to produce sequential red, green and blue images at a high rate on the screen. The natural persistence in our vision integrates these sequential images and produces a color picture on the screen. The faster the sequence, the easier it is for our eyes to integrate the colors. One of the problem associated with single DLP projectors is the "rainbow effect" often seen when the color sequence becomes apparent during fast motion or when the viewer's eyes move rapidly. Some people are more sensitive to this effect than others. To minimize this problem, the ScreenPlay 7200 uses a new six-segment color wheel (Red-Green-Blue-Red-Green-Blue) that runs at 9000 rpm. The result is video projecting the RGB color sequence 300 times per second or five times the 60 Hertz frame rate. This helps reduce the "rainbow effect" phenomenon for a lot of viewers.

DLP technology is really quite amazing when you look at how it works. The array of 1280 by 720 pixels are individually controlled and determined by the incoming video signal. Each pixel toggles between two discrete states (on/off) and a high rate. In other words, the micro-mirrors don't tilt slightly, but rather tilt completely (12 degrees) from end-to-end. By varying the duty cycle (on-time versus off-time) and keeping the frequency fixed, the different levels of brightness or shades of gray are produced and synchronized with each of the three primary colors to create the picture. The end result is a beautiful, high contrast image, especially with the new HD2 DLP chip.

Setup
Our setup included the ScreenPlay 7200 with a 100" diagonal Stewart FireHawk screen mounted on a Luxus Deluxe ScreenWall. The FireHawk is an excellent compliment to today's DLP projectors; It has a gain of 1.35 and a wide viewing angle of 100 degrees. FireHawk's ability to resist ambient light in the room helps maintain a high contrast image. In addition, the gray characteristics in the screen coating deepens the black level to further enhance the already impressive HD2 DLP chip. We mounted our projector from the ceiling and positioned it to minimize geometric errors. No lens shift adjustments are provided, so the projector must be mounted correctly to avoid using the digital keystone adjustments. The keystone adjustments tend to degrade the image quality, so ideally we prefer not to use them. Zoom and focus on the 7200 are fully manual, so it's a good thing this is a one time setup. The zoom lens is actually more powerful than many projectors we have seen. This allowed us to project a 100" diagonol image onto our 16:9 FireHawk screen at a distance of about 13 feet. We didn't get prefect geometry due to the optics, but it was very close to ideal, allowing us to slightly overscan on the screen. The VeLux material on the Luxus frame absorbed the entire overscan, resulting in a perfect looking 16:9 image from our seating position.

Connectivity
The rear panel of the ScreenPlay 7200 has a variety of video inputs including both analog and digital interfaces. One composite and two S-video inputs fully compatible with NTSC, NTSC 4.43, PAL, SECAM standards are provided. There are two component (YPrPb, 3 RCA jacks) video inputs and one VESA (15-pin D-sub) input. The projector can actually accept either component or RGB with sync-on-green on the RCA connections labeled "component". The VESA input can also run in either component or RGB/HV formats for the ultimate in video interface compatibility. However, the user must select the correct Color Space option in the setup menu. All common formats (480p, 720p 1080i and 1080p) are supported with these inputs. The ScreenPlay 7200 also has a rather unique M1-DA connector that greatly resembles a standard DVI connector. There are two adapter cables available from InFocus for connecting to the M1-DA connector. The DVI-D to M1-DA adapter cable (Part number: SP-DVI-D) includes a 24-pin male DVI-D connector and a 4-pin USB interface. The DVI-A to M1-DA adapter cable (Part number: SP-DVI-A) includes a standard analog VESA (15-pin) male and a 4-pin USB interface. Both cables are just over 6 feet in length. The DVI-D interface is fully DVI/HDCP compliant for encrypted content. A D-5 connector is also provided on the ScreenPlay 7200, but we did not test this interface. Additional connectors include a pair of 12V triggers for screen control (drop-down screens or curtains) options and an RS232 interface for serial commands. Professional installers may also take advantage of the serial interface for full control of the projector settings.

Remote
The infrared remote supplied with the ScreenPlay 7200 is small and lightweight with a well designed backlight for the dimly lit home theater environment. Pointing the remote at the screen to command the projector (positioned well above our heads) worked flawlessly. The remote is simple with the menu navigation buttons (Menu, Select, Up and Down) located at the top. The screen Resize button along with the dedicated Contrast and Brightness controls are located near the middle of the keypad. Just below this are four video input buttons, each of which can be defined by the user based on the video connections on the rear panel. The fifth source button cycles through all of the video inputs in the event the four main video buttons don't cover all of the connected inputs. Using the aspect ratio menu, the user can select Native, 16:9 (1.78:1), 4:3 (1.33:1), Letterbox, and Natural Wide modes. The Native mode looked the best since full resolution of the display is maintained. However, having different screen modes increases the flexibility of the display with the many different video sources available. Finally, the Preset button recalls one of three predefined user settings.

Several more advanced controls are provided for the user. Image processing parameters that are adjustable include NR (Noise Reduction), Cross Color Suppression, 2:2 pulldown, Color Space (YUV or RGB), Gamma (Film, Video or PC), Color Temperature (6500K, 8200K or 9300K) and Video Standard (Auto, NTSC, PAL or SECAM). Phase and position controls are also included in these menu items.

Color Tracking
We connected our Sencore VP300 video generator to the 15-pin D-sub connector and ran 720p video in the RGB/HV mode. We set the black level using the PLUGE pattern and checked the stair step levels to ensure we had properly adjusted the display. Using the menu settings we selected the 6500K color temperature and proceeded to check color tracking accuracy. Using our Sencore CP5000 All-Display Color Analyzer, we measured the color temperature in 10 IRE increments starting with 20% IRE. Amazingly, the ScreenPlay 7200 tracked 6500K very well across all measured IRE levels. Our lowest reading was 6412K at 100 IRE and our highest was 6526K at 60 IRE. Having measured such good data from the screen, we didn't feel the need to adjust the color tracking. The ScreenPlay 7200 does provide both Gain and Bias controls for fine tuning the color temperature.

Display Primaries
We measured the primary colors produced by the ScreenPlay 7200 using our GretagMacbeth Eye-One Pro Spectrophotometer along with the Milori ColorFacts software. The CIE chart shows where the ideal primaries are located with the smaller three points with the darker lines joining them. The measured primary colors are marked by the red, green and blue markers connected together with the white triangle. Only colors inside this triangle can be generated by the display. The bottom line is colors looked excellent overall with deep reds and rich blues. Green was not as deep as I've seen on some displays, but still looked quite impressive. Flesh tones looked beautiful with this projector.

The light output of the ScreenPlay 7200 running in high power mode produced over 1000 lumens. We measured 58 foot-Lamberts on our 87-inch wide Stewart FireHawk filmscreen which has a gain of 1.35. Although blacks were not completely black in our dark theater environment we found the projector produced the best picture in a dimly lit room. The standard lamp mode decreased light output slightly and improved the black level in a dark room. This also increases the lamp life by 50% to 3000 hours as compared to the 2000 hour life in the high power mode.

Faroudja Processing
One of the great attributes of the ScreenPlay 7200 is the inclusion of Faroudja's latest deinterlacing and scaling chip (FLI2300™). One of the common problems with film-based movies on DVD is properly deinterlacing the video to eliminate interlacing artifacts. The Faroudja video processor detects the 3-2 pulldown sequence by storing multiple fields of video and determining the original film frames. Once the original 24 fps (frames per second) film frames are recognized and reconstructed, 60 Hertz video frames can be generated with minimal artifacts. Faroudja's Cross Color Suppression detects and corrects cross color artifacts that often appear as 15 Hertz flashing colors or rainbow patterns. Advanced motion detection selectively performs temporal filtering only where there's no motion in the image. This technology works on all sources recorded from a composite video signal.
Faroudja refers to these algorithms as their DCDi processing. The performance of this deinterlacer and scaler was excellent. Watching DVDs revealed virtually no significant artifacts from the deinterlacing and scaling process.

The color decoder worked well with the composite and S-video inputs. However, the composite input should be avoided whenever possible. Luminance and chroma separation always results in some artifacts and with this high resolution projector you are almost guaranteed to see some of them. The S-video inputs looked better, but still require the color decoder to derive the component color signals. As a result, the picture didn't look as good as the component and RGB inputs on the projector.

Performance
Watching high-definition material on the ScreenPlay 7200 was truly breath taking. High definition material spoiled us making it difficult to watch anything with less resolution. DirecTV HD came from our RCA DTC100 using the analog RGB interface. DirecTV is offering more high-definition channels with the recent additions of Discovery HD Theater™ and ESPN HD. These compliment the already popular HD-Net, HD-Net Movies, HBO and Showtime HD channels offered on DirecTV. We also watched some over-the-air programs with this set-top box. We also saw the benefits from the DVI-D interface as we took advantage of our Samsung SIR-T165 set-top box. The Tonight Show broadcasted in HD here in Los Angeles looks great. The advantage of using the DVI-D interface is that there is no need to convert the signal to the analog domain. Unfortunately, DVI-D cables do have length limitations, so this has to be factored into the installation of the projector.

Our JVC HM-DH30000U D-VHS VCR was a great source for pristine high-definition video. HD-Net provided a tape from their Bikini Destinations series and the quality was truly reference material. Skin tones were very natural looking with subtle details revealed. Even though the video coming from our digital tape was 1080i, the ScreenPlay 7200 did an admirable job of converting the video to the projector's native display resolution and scan rate with no noticeable artifacting. We also watched several D-VHS D-Theater movies on the JVC including Galaxy Quest, Kiss of the Dragon and U-571. These high-definition movies were equally impressive on the ScreenPlay 7200 with just a bit of low level video noise which seems to be somewhat inherent in the telecine process when going to digital tape.

While DVD resolution is considerably lower than the high definition material we loved to watch on this projector, the picture quality looked excellent with our favorite material. Scenes from Shakespeare in Love produced accurate flesh tones with good color saturation. Dark scenes had impressive shadow detail while still maintaining deep black levels.

Conclusion
The InFocus ScreenPlay 7200 is a high performance projector capable of producing a stunning high definition picture. If you have this projector you will want as much HD material as you can get your hands on. The light output and contrast ratio of the ScreenPlay 7200 works incredibly well in rooms that have some ambient light, especially when combined with a quality Stewart FireHawk filmscreen. The high performance, ease of use and straight forward setup makes this projector an excellent candidate for serious home theater enthusiasts. We will really miss this projector after the review period.
