Cons - Useless Auto Iris. 3D glasses are expensive and separately sold.
I've had this projector for about a month now and have been watching more TV than ever. This is my first projector and I spent some time shopping around and viewing different projectors. I had shopped in local stores and saw several on display, usually Sony or JVC. They both looked okay but I didn't like the motion blur or 3D picture on those projectors. The Sony had a setting that tried to smooth the picture but it made it look totally fake. This projector is a DLP, and apparently some people see a rainbow effect, but I never have and no one else in my household does either. Kind of like seeing unicorns maybe!
Our regular TV watching and sports watching are great. But Blu-Rays take it to another level. The clarity and image quality is beyond what I've seen even at my local theater. Movie watching is where this projector really shines. We also watched 1080P movies streamed on line and it was the same stunning picture quality. It might be the 1080P setting, because the XBOX games are 1080P and they too look amazing.
My screen is a 115" Black Diamond 1.4 gain Zero Edge screen from Screen Innovations (16:9 Format). My room is specifically set up as a dedicated home theater and very dark, so ambient light is not an issue. I have two rows of seats at 12 feet and 18 feet from the screen. A majority of viewing is DirecTV and sports, so we generally have some lights on. This projector on this screen is plenty bright, and I use Low lamp mode. The colors are natural looking and not overly saturated. The image appears sharp and I do not see any judder or motion blur, which I was concerned about on a screen this big. My main reason for DLP was the limited blurring of sports and gaming (have an XBOX connected to the system) and the superior 3D. I was told that blacks might look greyer on this projector, but I haven't noticed this at all. In fact, there is an Auto Iris that attempts to improve the blacks, but it tends to darken the corners of the image and creates hot spots on the screen, so I don't use it. To me, this seems like a useless feature, because the blacks look fine without it, and the distorted picture brightness when this feature is on is really annoying.
There is a motion control setting that can smooth the image. There are 10 settings, with 5 for video and 5 for film. I usually keep it on the Film 4 or 5 setting which is in the middle overall. Video is the more aggressive setting and Video 5 makes the image look a little fake - too smooth. What they call the Soap Opera effect that bothered me so much about the Sony.
There seems to be a lot of settings and memory to set those settings, but I haven't done too much with those. I basically use the "Cinema" preset setting and it looks like a great picture. In fact, I like the image quality of this projector better than the local theater.
3D is absolutely amazing. The glasses aren't cheap and I had to buy separately, but the image is amazing. You probably haven't seen 3D this good, even in a movie theater. I tried 3D on other projectors and really didn't like it at all. Too dark and often juddery or blurry. I was ready to give up on 3D for the home but figured DLP might deliver. Boy did it with this unit. It's a very enjoyable feature.
Not sure if it's the projector or the screen, but I might be pushing the limits of the technology with this set-up. At 12 feet on a screen this big I can just start to see the graininess of the screen/projector pixels. In my second row at 18 feet, there is no issue. The projector is plenty bright on a screen this big, but if you sit any closer than 12 feet you probably want no more than 120" screen for this projector. My installer thinks newer units that display 4000 lines of resolution might solve that, but those are thousands of more dollars than this. The screen might be contributing to this too. But, the large screen is incredibly immersive.
Overall, a very good value with this projector. Paired with my screen, it looks like a plasma on the wall - a very big one!
That swayed my decesion and I ordered the Mits.
Have it coupled to our Home Cinema as a secondary HD display behind a 55" LG LCD flat panel. We installed a Elite Screens 100" motorized acoustically transparent screen to come down over the LG so we would be able to enjoy 3D cinema in the same home theatre room.
Audio is a powered by the Yamaha RX-773WA AVR coupled to JTR speakers in a 5.1 configuration. By the way, if you've never heard of JTR speakers, google them. They are absolutely stunning speakers to hear and are the finest speakers I've yet to hear under 2000.00. We have Triple 8's as our mains, Quintuple 8 as the center, Single 8's as the rears. LFE is being provided via a Polk 505 powered sub. (I would love anything to go with the JTR Captivator powered sub but sheesh 3.5k for a single speaker is up there).
We use our Home Cinema for predominantly BluRay movies, online streaming services (Netflix, Vudu and Amazon Video) with console gaming (PS3 & XBOX 360).
Back to the projector.
Out of the box it will need some calibrating. Colours seemed to very muted and the blacks were almost gray. After about 30-45minutes of calibration I got the projector showing a simply stunning 2D image. Wow, words cannot describe how stunning the image is from this projector in 2D.
I personally was afraid of the dreaded DLP rainbow effect and how some people see it but others don't. I was glad to find out that I am not receptive to DLP rainbowing. My Wife on the other hand unfortunately sees it with fast moving objects on screen.
You will definetely need to sit down and read the manual. The menu options on this projector are deep and there were options that I've never even heard of when it comes to TV's.
The projector only comes with a vertical lens shift which means you have to drill your ceiling mount right spot dead on to your screen.
We have the screen to projector distance at exactly 10' and I was very surprised that we were able to almost fill up the entire 100" screen at such a short throw distance.
Warning: if you use an acoustically transparent woven screen material like we had to use, you will see tesellenation or moire effect at a seating distance of 8' or closer. It takes some getting used to or you can throw the projector slightly out of focus a smidge to minnimize the effect. I only see it during brightly colored scenes.
I did find the projector to be a bit dark for me when using the Low-Lamp setting and I actually now prefer using the Standard Lamp setting. The projector's fan does spin faster and louder but you won't hear it unless there is absolute quiet in the movie.
Now for 3D.
Wowzers!!! 3D on a 100" screen is beyond amazing. A feature we had been paying for down at our local Cinemark 22 is now right in our living room.
Want to add that the standard Mitsubishi IR 3D glasses that are made for this projector are dreadful in appearance and in comfort. Since they are IR this requires the use of the included IR-Emitter and nearly a direct line of sight to get the glasses to synch and stay synched. Another weird thing about using the IR-Emitter for 3D is that it drowns out almost every other IR remote in the room. I found my remote unable to communicate with my AVR or Bluray player during 3D movies unless I actually closed the distance by walking near them. Even the projectors own remote had serious issues communicating with the projector during 3D movies. The manual does state that this is a known issue and does warn the user.
I really wanted to use the Monster Active 3D glasses and IR to RF converter. Those glasses are much more comfortable and since they are RF instead of IR, you can actually move your head and even goto another part of the house and never lose synch with the projector.
Bought the Monster 3D kit and the converter and even though Monster states that the converter is totally universal and will work with hundreds of 3D displays, it unfortunately does NOT work with the HC7800D.
However... there is an online tutorial on how to build a 5-Pin to 3-Post 3.5"mm plug adapter cable to get the projector to send the 3D signal directly to the Monster 3D Active RF transmitter and skip the IR to RF dongle device.
I will say it took me roughly an hour to cut and modify a spare 5pin din cable and a 3-post 3.5mm audio jack. Followed the online instructions, (just Google it), tested the leads after stripping the cable and soldered the ends together and wrapped the break in electrical tape.
Sending back the goofy Mits glasses which are insanely dark during 3d movies and are now using the Monster Active 3D RF system with the 3D active glasses, which are 100% brighter, wider viewing angle and a ton more comfortable.
You will have to download the online pdf manual for the Monster Active 3D RF system so you can see how to fine tune the synch signal from the HC7800D to the Monster Glasses. Honestly this took me less than 30mins to accomplish. Ghosting, blur and color were 100% eliminated.
If you do this modification and don't fine tune the Monster Active 3D RF transmitter, you will be looking at a blue washed screen, with terrible ghosting and blur. Just use any 3D Bluray movie and let the menu screen keep looping. I used Tron: Legacy and dialed in the fine tuning.
3D is now brillant.
Tron Legacy looks like a actual portal into another world. It literally looks like you could step through the screen onto the other side.
Prometheus and Avengers were also jaw dropping in 3D. Once you go 3D you will be hard pressed to go back to 2D and long for the day when all diplayed media will be in 3D.
Console gaming is simply put FRIGGIN AWESOME. Killzone 3, Motorstorm: Apocolypse, and God of War: Origins pack cannot be described in a review. You need to experience the act to actually appreciate it.
I am totally convinced that I made the right decesion in choosing this projector.
It will take a little patience with the calibration to get the HC7800D to display an amazing screen and the 3D glasses modification when completed will open up an entire new market for 3D glasses choices.
I'm happy and I hope my lengthy review will help others decide on this projector.
I'm using it with a 150" screen that is 7 meters away from the projector and the image is nice.
I higly recommend buying it
