Long Lamp Life

Keep your maintenance to a minimum. The MX511 offers normal and economic lamp modes, and the latter will give you up to 6000 hours of life, which is double the lamp life expectancy of many projector lamps.

Go 3D with DLP Link

The MX511 is equipped with 3D projection technology, for immersive 3D effects in your own home. It utilizes DLP Link 3D technology. As with many of the 3D TVs on the market, the user wears compatible active shutter 3D glasses. The difference is that DLP Link requires no emitter device to control the glasses--it sends open/close data as video, in between frames. Using the MX511 for 3D will require BenQ's 3D glasses and 3D content (delivered via playback software or compatible DVD/Blu-Ray players).

BenQ MX511 Rear
Features an HDMI input, along with a wealth of analog inputs.
XGA Native Resolution

The MX511 features XGA native resolution, e.g., 1024 x 768, which brings you crisp and accurate images for your presentation.

High Contrast Ratio

With a high contrast ratio of 3000:1, you'll get sharp detail and a broader range of subtle color differences, which makes text sharper, cleaner, and easy to read.

2700 ANSI Lumen Brightness

This ensures great viewing for small- or medium-sized rooms, even in locations with ambient light.

Vivid Color

The MX511 features BrilliantColor Technology, which boosts mid-tone colors to increase overall brightness, for a more life-like picture. BenQ's "3D Color Management" lets you adjust six colors (primary/secondary) for permanent installations, to allow for more accurate reproduction.


The MX511 features an HDMI input, for a convenient audio/video connection to most modern digital a/v devices. Composite, component, and other connections are also provided.

Built-in Speaker

The MX511's built-in 2W speaker gives you simple mono audio solution during presentations. A stereo output is also included, for attaching stereo speakers or sending audio to a separate system.

3D Technology Checklist

This product is 3D-related. To help you get a great 3D experience, use our checklist below to ensure that you have everything you need. If you have any questions or want to learn more about 3D, we invite you to visit 3D 101--our center for everything 3D. To get started with 3D, please ensure that you have:

A Display

The first--and most important--item you'll need is a 3D-ready display--whether it be a 3D HDTV, 3D projector, or 3D computer monitor. These displays usually have a higher processing power than older models as they need to display one image for each eye to create a 3D effect.

A Source

While your display is ready for 3D playback, you still need a device to read 3D content (i.e., a movie or a show). This source can be a cable box with a subscription to a 3D channel, a 3D Blu-ray Disc player, or a PlayStation 3.


In order to watch 3D, you will need to get some 3D content. This 3D content will come from the source mentioned above in the form of a 3D program, movie, or game. Please ensure that your 3D movies are in the Blu-ray 3D format, as this new format will provide the best 3D experience.

3D Glasses

All 3D HDTVs on the market require Active Shutter glasses to create the 3D effect. You will need to buy one pair of glasses for each viewer. Also make sure that the Active Shutter glasses you buy are compatible with your display--for example, buy the glasses from the same brand as your 3D HDTV.

HDMI Cable

To connect your source (such as a 3D Blu-ray Disc player) to your display, you'll need a hgh-speed HDMI cable. Cables with this designation--with bandwidth speeds up to 10.2 Gbps (gigabits per second)--will be able to carry the 3D signal without any loss of quality.
If you want to get more information about 3D, shop our 3D products, watch videos, or interact with other customers, visit 3D 101, our customer center about everything 3D.

BenQ MX511 is 3D ready but it does not support HD source for 3D. You can see 3D only using composite (yellow) or s-video cable (advised by BenQ tech support). To see HD 3D you need HDMI 1.4 input and this projector only support HDMI 1.3 input. I hooked up Sony 3D Blue ray player (BDPS470) with HDMI 1.3 to this projector and this combination was not able to project 3D image on screen. It automatically playback to 2D/1080p. Menu Option in BenQ for 3D setup also got disabled/turn off with this setup. I have checked with composite cable to see 3D with DLP link ready glass and 3D was horrible with no depth, seems like 2D.

I am really quite pleased with this projector. Wanted a projector to replace my very old NEC SVGA one with hdmi for xbox gaming and dvd/etc in the basement and i am now projecting about a 5ft high image on a white painted wall. Was looking extensively for months, comparing lamp life, native output, etc, etc, and waiting for something acceptable at the price point i wanted. Found this one for $449, which was well below what i expected to pay, but there is no comprimise.

DVD quality was excellent as well. I played a few games of Black Ops standing up, and found myself trying to look around corners and up over things. For the price and with 3d ability(which i cannot comment on yet), i could not be happier. Colors are really good with a # of preset and configurable settings via the small remote. Audio is obviously not going to knock your socks off, as i haven't run it through the amp yet, but it is still more than acceptable. Kicks my upstairs HD toshiba picture actually. Great deal and no real compromise for an excellent viewing experience for those not 'needing' it to be the absolute best there is out there.

I have had this projector since January 2012, have put about 110 hours on it so far.
I am including the guide on how to run 3D from your computer onto this projector below. but first pros and cons.
I bought it for 350 from staples canada (toronto)

Great picture quality
Great color reproduction
All the standard features + hdmi

Loud fan (according to my standards, others may think its alright)
very poor instructions in the 3D department from Benq, and thats where they lost the point.

How to run 3D on this projector.
1- Buy the glasses. (I got "Sintron" 3D glasses from ebay, they work very well)
2- secure a VGA cable. (HDMI will not work, dont waste your time)
3- download the "stereoscopic player" from (dont buy it yet, just download free first try and see if 3d works for you)
4- connect the projector via VGA and go to display properties -> advanced, set the resolution to the highest resolution possible at 120Hz. its important to set it at 120 HZ (may also work at 100HZ but 120 is better)
5- Press the menu button on projector's remote, you will see that the 3D is now available, select 3D and turn it on.
6- open your stereoscopic player and go to File -> settings -> playback options. in "Viewing method" pick "Software pageflipping" in "glasses control" pick "DLP 3D Ready Encoding". under Preferred viewing methods Stereoscopic pick "Software pageflipping".
7- hit ok.
8- now play your SBS movie and it should be throwing 3D on the wall.

P.S: if you didnt turn on your 3D glasses. smack your self :) .

I hope this helps

i purchased the mx511 about three months ago. i have to say it's awesome. hdmi works great. it's the only thing i have hooked up. i have it hooked up to my directv and ps3. i am running through a viewsonic vp3d1 adapter. i am using cheap 3d dlp link glasses made by futurecinema.. i am totally pleased. if you shop around, you can get this unit for around 450.00 and less if refurbished. i am not going to waste you time talking about the clarity of the picture. it's awesome. i have watched 3d through espn 3d, 3net, on directv and it looks great. i have also bought and watched tron:legacy, resident evil:afterlife, piranha, the green hornet, alice in wonderland, tangeled, cat and dogs 2. as i said before, they look great. regular blue rays play perfect. if there is one the to gripe about it's about my samsung ht5500 bluray surround. hdmi doesn't pick up thru it. i have heard that samsung has had the same problems with certain manufacturers. not a deal breaker.

Dec 9th 2011 update. samsung blu ray system works . had a bad 45 foot hdmi cable

For the price you just can't go wrong! I have been using this for almost two years now and have not had one problem with it. I run it in my basement on eco mode and the picture looks good even with some lighting on, it doesn't have to be pitch black in the room. I still have a lot of hours left on the ligt bulb. The fan noise isn't to bad at all either. I would recomend this to anyone looking for a projector.

I loved this projector until just 1 month out of warranty when the pixels started getting stuck. In the course of just 3 days 70% of the image is completely obscured by white or black pixels. It will cost nearly as much to repair as for a new projector, so it's going in the trash. Didn't even use 20% of the lamp life and it's already dead. It's a good projector when it's alive, but don't expect it to last.
