Mitsubishi HC7800D 3D DLP
High Definition Projector

By Kevin Nakano

Mitsubishi HC7800D 3D 1080P DLP ProjectorMitsubishi's new HC7800D is a mid-priced DLP-based projector capable of 3D 1080p video. The projector offers 1500 ANSI lumens of light output with a contrast ratio of 100,000:1, thanks to the newly developed variable iris that can respond to continuously changing (bright and dim) scenes. The high-performance extra-low dispersion (ED) 4-cluster, 13-piece all-glass lens provides excellent focusing and features 1.5x magnification. This single DLP (0.65") projector uses a 6-segment (R,G,B,R,G,B) color wheel to maximize performance. The HC7800D features motion-vector analysis for its integrated 2D to 3D conversion technology designed to bring standard 2D pictures to life in 3D. The HC7800D also supports Deep Color and utilizes two 10-bit panel (DDP3021) drivers that produce approximately four times the gradation of 8-bit models. This virtually eliminates the problems associated with subtle gradation steps that can be visually distracting. Video processing takes advantage of Trident's PNX 5130 frame rate conversion (FRC) for smooth motion during playback.

The unit we received also came with a single pair of 3D active shutter glasses (Model# EY-3DGS-78U), which are not standard issue. These 3D glasses must be purchased separately for $199 (each). The design is a bit on the large size, but worked very well. We tried some third-party glasses, but none of them seemed to work with this projector.

Mitsubishi HC7800D 3D 1080P DLP ProjectorThis HC7800D can be used with an anamorphic lens — a feature not commonly found in this pricing category. The flexible internal scaling allows an anamorphic lens to be permanently installed regardless of the source material. This greatly simplifies the screen and eliminates the need for sophisticated and costly screen options when viewing 2.35:1 or wider aspect ratios.


Mitsubishi HC7800D 3D 1080P DLP ProjectorTop Controls
The lens adjustments on the HC7800D are all manual with the zoom and focus controls easily accessible. The vertical lens shift control sits under the top cover. There is no horizontal lens shift on this projector.

Power and menu controls are available, but are not likely to be used by most of the users installing this projector from the ceiling or back wall. The Status indicator provides feedback in the event the unit overheats or the bulb fails. Some of the buttons have dual functions when the menu is active or when setup adjustments are being made. This is most useful when using the projector in a tabletop configuration. We had little use for these controls since our projector was mounted inverted on the ceiling. The Power and Status indicators provide information about the projector's power state and lamp condition.


Mitsubishi HC7800D Lamp ReplacementLamp Replacement
The lamp (VLT-HC7800LP) in the HC7800D is designed to last up to 5000 hours (low mode), which is significantly longer than most projectors.
When the lamp operation time exceeds 5000 hours, the projector automatically shuts off and can’t be used until the lamp is replaced and the lamp operation time is reset. Mitsubishi has made it simple to replace (MSRP $349) the lamp in the HC7800D. This lamp module is located next the projector lens and is accessible once the lamp cover is removed. Simply remove the two screws that hold it down and the lamp can be pulled out using the handle.


Mitsubishi HC7800D RemoteRemote
The HC7800U remote leverages from earlier Mitsubishi designs that offer a practical layout that is also easy to read in poorly lit rooms with the backlit keys. When any of the buttons are pressed, the backlight illuminates all the keys. The remote operates on a pair of "AA" batteries and the original ones that came with the remote are still working even after several months of frequent use. Separate power ON and OFF buttons help prevent accidental shut-off . Turning the projector off requires two successive presses of the OFF button. Three dedicated input buttons are used to select from HDMI1/2, PC, and Component inputs. There are buttons for Picture Mode, Frame Rate Conversion, and Color Management. A set of three A/V memory buttons are included for custom configurations. The navigation buttons (left, right, up and down) work in conjunction with the Menu button. The IRIS button controls the setting of the automatic dynamic iris. Picture controls for Gamma, Sharpness, Color Sat (saturation), Brilliant Color, Anamo (anamorphic), and Auto Position are also present. The HC7800D has IR sensors on both the front and back of the unit, making it responsive with different installation options.


Mitsubishi HC7800D InterfacesInterfaces
The rear panel of the HC7800D accommodates both analog and digital video interfaces including component video, 15-pin RGB/component, and two HDMI v1.4 inputs. The two HDMI digital interfaces support 10-bit and 12-bit video in addition to the current 8-bit color, resulting is less color banding and false contouring often found in earlier projectors. Standard video formats supported are 1080p/60/30/24. 1080i, 720p, 576p, 576i, 480p, and 480i. Computer resolutions as high as UXGA60 (1600x1200) are supported as well. The HC7800D supports the following 3D modes: Frame Packing (up to 1080p24), Side by Side (up to 1080p60), and Top and Bottom (up to 1080p60).

Having two HDMI video interfaces on the unit offers more options when connecting equipment. There is an RS232 port that can be used to command the projector from an outboard controller. An IEC power receptacle is located here and accommodates a wide range of power source options (100V-240V, 50/60Hz). The 12-volt trigger outputs can be used to control other devices such as motorized screens and anamorphic lens assemblies and provide up to 200mA of drive current.

Mitsubishi HC7800D IR EmitterThe IR emitter that comes with the HC7800D is used to synchronize the 3D glasses and interfaces to the back of the projector using a mini-DIN connection. The emitter has a high output level so that anyone in the room will receive a good strong signal when watching 3D content. In fact, we found that this IR beam is so strong that it can sometimes interfere with other IR devices in the room such as remotes used for A/V receivers and BD players. Users may have to adjust the placement of this IR emitter to maximize the performance of their 3D glasses, while preventing interference on the other IR devices. If you happen to be using an RF-based remote controller to send commands to your components, you will not have any issues with this device.


Installation
The HC7800D has a manual 1.5x zoom with a manual vertical lens shift with a significant upward throw limiting options during placement. A minimum of 6.5 degrees is required between the projector and the top of the screen when mounted inverted, so placement planning is important. This can be a challenge depending on the ceiling height and the screen size. There is also no horizontal lens shift on this projector, so users need to be mindful of this prior to installation. Mitsubishi has a great projector calculator at their website to help with the installation of the HC7800D. We would recommend taking a look at this to get a feel for what is needed in your theater room.

Chief SLMU Universal MountMounting
We have a Chief RPA Elite Projector Mount that holds the Anthem LTX-500v projector in our theater room. When we have other projectors to review such as this one, it is nice to use the Chief SLMU Universal RPM Interface Bracket, which makes it easy to adapt to virtually any other projector and use the same wall mount hardware. We were quickly able to mount the HC7800D and it didn't require any special hardware to get the projector in place while leveraging from the existing wall mount. The HC7800D only weighs about 12 pounds, so it was very manageable.

The zoom range on this projector will require the projector to be fairly close to the screen. Our 100-inch Stewart FireHawk needed to be placed (projector lens to the screen) between 120-inches (10-feet) and 180-inches (15 feet). The vertical lens shift helps maintain near perfect geometry when the projector is placed above the screen. The HC7800D features up to ±15 degrees of vertical digital keystone correction. However, the keystone setting is invalid (restored to the default setting) while you are watching the 3D images. Even with the projector mounted directly over our heads, the fan noise was fairly quiet, but not silent in the Low Mode (25dBA). The fan was slightly more noticeable (31dBA) in the Standard Mode. Both focus and zoom are fully manual on this projector. In general, we feel that this was a good move to reduce cost since these controls are only needed when the projector is being set up. I have always had a hard time justifying the cost associated with one time settings.

We connected only a single HDMI cable to our HC7800D review unit. All video content was sent over an Accell Corporation UltraRun™ 1.3 (25-meter) HDMI cable from our Anthem AVM 50v 3D pA/V processor. Our sources included a DISH Hopper, OPPO BDP-103 BD player, and a PlayStation3. We didn't bother testing out the analog interfaces on this projector since all our video sources use HDMI.

Mitsubishi has a color management function for easy fine-tuning of colors on the HC7800D that allows users to dial-in their color preferences. The Gain, Saturation, and Hue levels for red, green, blue, cyan, magenta and yellow can each be adjusted individually without affecting the color quality of the other colors. This level of adjustability is a bonus for those videophiles looking for perfection.


Display Primaries
Mitsubishi HC7800D Color AccuracyThe color accuracy of the HC7800D was excellent with the primary and secondary colors measuring near ideal. Our measurements were read from our 100" Stewart FireHawk filmscreen using the GretagMacbeth Eye-One Pro Spectrophotometer along with the Milori ColorFacts PRO software. The CIE chart shows where the ideal primaries are located with the smaller three points joined by the darker lines. The measured primary colors are indicated by the red, green and blue markers connected together with the white triangle. Only colors inside the triangle can be produced by the projector. Each primary and secondary color measured very closely to the reference standard with green slightly shifted towards yellow. This is somewhat common in many of the projectors we have reviewed. Both red and blue were right on target and the secondary colors were quite accurate as well. Obviously, the color accuracy measured here had much to do with the excellent color performance we experienced with this projector. Flesh tones took on a very natural look and color saturation was excellent. Greens were lush and blues were deep.

Mitsubishi HC7800D Grayscale TrackingColor Tracking
We took readings from the projector using the Cinema Picture Mode. This setting forced the Gamma Mode to Cinema, Color Temp to Medium, and the Lamp Mode to Low. Color temperature readings were close to the ideal 6500K and just a little on the high side for IRE levels of 30% to 100%. The lower IRE reading near 20% is where our meter starts to lose accuracy, so an instrument error may have contributed to the lower than normal reading seen in the chart. We checked the black level using the PLUGE pattern and it was perfect at the 0 setting.

Light output in this video mode was still quite high measuring over 15 fL on our 100-inch screen. Switching to the Normal lamp mode with the color temperature set to High Brightness pushed the light output to 45 fL, but shifted the color temperature to around 7700 K.


Immortals 3DPerformance
Video performance was good on this projector regardless of whether it was standard 2D or the full depth offered in 3D. Much has to do with the current DLP technology, which provided good motion detail when compared to the motion blur often seen with LCD or LCoS technology. We started with some 3D content being beamed down to our DISH Hopper satellite receiver. Like most of the 3D glasses I have used, the ones designed to work with the HC7800D are bigger than I would prefer. However, they work well, fit comfortably and provide excellent performance. We then moved to Blu-ray content played on the new OPPO BDP-103. We just happen to have Immortals in both 2D and 3D, so it was a nice comparison to see the difference. Personally, 3D viewing is a bit more work than I like and so for me it is even more important that the projector be capable of producing an equally good 2D picture if not better. Fortunately, the HC7800D delivers a satisfying picture, but does lack somewhat in reproducing deep blacks. The auto iris feature does help in this area, but it doesn't come for free as it chokes off the light output of the entire picture when trying to deepen the black levels. The response time is fast and it is certainly a reasonable trade to increase contrast. Ultimately, personal preference will dictate the best iris setting. Even with some ambient light bleeding into our theater room, the HC7800D was able to deliver a bright usable picture when asked to do so with a higher output setting with some sacrifice to picture accuracy.

Conclusion
The latest HC7800D is a high performance 3D 1080p projector that has equal 2D performance as well. If you are not sensitive to single DLP color wheels, then you will appreciate the performance this unit has to offer. The picture is punchy with reasonably good native contrast and offers first rate video processing. The new high speed iris on the HC7800D brought the black levels even deeper than what DLP technology is natively capable of. The onboard Trident video processor did a good job with motion on a variety of content. The adjustability of this projector is also a big benefit for those video enthusiasts looking to dial in perfect picture settings, but installers need to pay attention to the placement since adjustability is somewhat limited. The current street price for this projector is well under $2000 at this writing, making the HC7800D a particularly attractive projector.
