  • 1. Can an Ipad be directly connected to a Data video projector?Revised March 26, 2012I have been getting asked this question a lot recently, so I thought I would dosome research and put the answer here. I work as a consultant for a leadingcompany offering data-video projectors, Dukane, so this is a concern for manypeople with existing Dukane projectors.The question: Is there a way to directly connect my Ipad to a data-videoprojector. This is, of course, the generic name for projectors that manyclassrooms and training rooms have for displaying the screen on a computer towhere everyone in a class or group can see it.The short answer: Yes.The follow up question: What do I need to do that?The Apple Store has 3 ways to do that. The first two involve an adapter,sometimes called a dongle. There are 2 Dongles, the VGA and HDMI version.I have put the link to all three below. The text in black comes from the Applestore.VGA adapter
  • 2. You will need a 15 pin Male to male VGA cable. That is the same cable thattypically comes in the box with most projectors.There are exceptions, it seems to everything in life and most things withtechnology, and there are some “non standard” cables in use with variousprojectors. But the 15 pin male-to-male VGA cable has been a standard foralmost 20 years now.I have tried and used this with my Ipad 2, so I can attest to the fact that it works.For some projectors, that may have only a single VGA input, you may have tounplug an attached computer, or invest in an A-B Switch box. An A-B switchboxis very affordable. As with anything there are good, better and best.Most Dukane projectors (not all, but most) have two VGA inputs; so you canhave a computer and Ipad attached, in that case, and simply use your projectorremote to switch back and forth.HDMI Adapter
  • 3. Use the Apple Digital AV Adapter to mirror whatever’s on your Ipad or iPhone 4S screen —apps, presentations, websites, and more — on your HDTV or HDMI-compatible display in up to1080p HD (movies play at up to 720p).Watch slideshows and movies on the big screen in up to 720p by connecting your Ipad, iPhone 4,or iPod touch (4th generation) to an HDTV or HDMI-compatible display. The Apple Digital AVAdapter routes digital audio to screens that support it. Connect the Apple Digital AV Adapter toyour Ipad, iPhone 4, iPhone 4S, or iPod touch (4th generation) via the 30-pin dock connector andto your HDMI-compatible display using an HDMI cable (sold separately).A second 30-pin connector built into the AV adapter lets you charge and sync your device whileit’s connected to your HDMI-compatible display.First of all, there may be those not familiar with the term HDMI. The acronym HDMI stands forHigh Definition Multimedia Interface. You can read more about HDMI here: put, it is new kind of Digital connection to go from a video source (a computer, an Ipad, acable TV box) to a display device (a projector, or an LCD Monitor or TV.OK, I have put the wording from the Apple Store above. I have not PERSONALLY usedthis HDMI adapter. I do see some comments on the Apple Store site about problemswith the Ipad 2 and latest Ipads.
  • 4. The good new for those acquiring a Dukane data-video projector is that ALL Dukaneprojectors that are currently available have an HDMI input and will work with an HDMIcable.That is NOT true of all projectors and particularly “historic projectors” including thosesold by Dukane in the past.In the case of a projector with only the RGB input, you obviously would want to use theRGB adapter.There ARE RGB to HDMI converters, but since most projectors have RGB inputs thatmay not be an issue.With technology, as with medicine, it should be the first job of those offering advice to“First, does no harm”.So I would encourage anyone who has a projector with HDMI and wants to use thisadapter to talk to their manufacturer, or Apple representative, or both, before trying thisHDMI adapter. I have talked to people who have used this adapter with no problem.I also want to make sure it is clear than with either the VGA dongle or the HDMI dongleyou will need either a VGA cable or HDMI cable to go from the Dongle on the Ipad theprojector or other output device(an LCD TV, for example).NOTE: Since I first wrote this article Apple has introduced a new Retina display Ipad andthe Ipad Mini. Both of them use the new “Lightning” version of the Adapter. There isboth an RGB and HDMI version. The Apple site has the specs and Q and A about these.One of the questions I noticed was that someone bought the HDMI version to use withtheir projector, and then figured out when they tried to use it with their projector that theirprojector only had RGB inputs.Here’s a tip. If you aren’t sure, take a digital camera or the camera on your phone andtake a picture of the back of your projector and take that with you when you go to buy anadapter.How about 3rd party “dongles?I have a trusted source for VGA cables and other peripherals here in Charleston, SC.They sell all kinds of electronic accessories and they are my source for VGA cables, if Ineed a longer one as well as USB cables. I asked them if they were selling a “dongle”compatible with Ipads and they told me they had no luck with copies of the Appleadapters, so as far as the dongle goes, I would stick with Apple, unless you have a wiserguru than mine.
  • 5. Apple TV Apple TV box will provide a wireless connect between an Ipad and a devicesuch as an HDMI ready projector or LCD Monitor.I have tried using my Ipad 2 with the LCD TV to which the Apple TV box isattached, and it works. Ipads have software called “Airplay” that allows this totake place.I have also talked to the technical guys at Dukane and they have schools usingApple TV boxes with projectors.There are two “cautions” I would point out.1-Not all Ipad apps are “Airplay friendly”. You have to check. That means theymay not “show up” when you use an Apple TV. With a direct connection,whatever is on your Ipad is going to show up on the projector or LCD TV.2-Since the Apple TV is on your network, and is dependent on the speed andreliability of your network, if you are in a school with dozens of Ipads, all hittingthe network at the same time, this may affect the speed at which the Apple TVworks.I would again, with this or any solution, talk to your IT director, Ed Tech director,Apple Rep and projector vendor. And where you have all 4, talk to all of them.Are the dongles and wireless solutions ONLY available from Apple?As I assume every knows, there is a booming market for Ipad accessories fromthird parties. So, yes, there are dongles and other video accessories availablefrom a variety of sources.
  • 6. But once again, you put yourself out on a technology limb if you use anaccessory that is not supported by both Apple and your projector vendor andblessed by your local tech people.My goal here was simply to make folks aware that1-That you Ipad CAN be used directly with a projector.2-And provide info on HOW it could be done .Do these solutions apply to an LCD TV?That is another whole document of course, and there are so many models outthere I hesitate to give a blanket “yes”.However, I have a 3 year old 42 Inch HD TV at home. It has both RGB and HDMIinputs on it. I have used the direct connect dongle from the Ipad to the TV and itworks to share the Ipad screen on the TV screen. Likewise I have an Apple TVbox and it works with my Ipad 2. So based on that personal experience( Ihaven’t tried the HDMI adapter but assume it works as well) I would say it doesapply to those LCD TVs that have those inputs. With so many of these LCD TVson the market I hesitate to say it applies to all.Cant I just use an “App” to mirror my Ipad?Someone wiser that me said keeping up with technology is like sipping from afirehouse. I am aware of, and tried some apps that offer a mirror image, andsome annotation capability on an Ipad.These generally require some software be installed on the host PC or Mac. The“app” then “talks to “ the computer via Wi-Fi. Therefore how well such an appworks will depend on several variables• How good is the Wi-Fi in your Ipad? The Ipads after the Apple 2 have improvedWI-FI built in.• How good is the Wi-Fi connection and how much traffic is there on the networkit attached to?I talked to someone who is of the caliber of an Apple system engineer and theyconfirmed my surmise. A lot of data has to go back and forth between thecomputer and the Ipad for video mirroring.
  • 7. The ones I have tried showed significant “lag”.Again, I haven’t tried them all, but I see a direct connection between the Ipad andthe video output device (Projector or LCD screen) as being fast and reliable. Thedongle and cable will “tether you “ somewhat, but with a long enough RGB orHDMI cable you will have a good range of motion.The Apple TV will make the “airplay-compatible “ apps work wirelessly, but again,your Apple TV will be as good as the WI-FI connection and your overall networkspeed.Illustration :The projector shown below is one of more than 2 dozen different models offeredby Dukane. With that said , the 8784H-RJ is a very affordable model and one thatis currently widely used in classrooms and training rooms. Dukane is also theonly manufacturer offering FIVE year warranty on most of their projectors. (Mostother projectors have a 2 or 3 year warranty).This graphic is shown here simply to illustrate the inputs mentioned above (the15 Pin VGA input port) .There are two such input ports on this projector, Labeledhere Computer 1 and 2.The HDMI input needed for the HDMI Adapter and cable , or for use with theApple TV is also shown.
  • 8. The other inputs are not relevant to the use of an Ipad, unless you also want tosend the audio from your Ipad, and there are audio input ports for that as well.You can find the full data sheet for the 8794H-RJ here: just saw a projector advertised that says it is compatible withan Ipad and I would not need a cable. Should I buy “thatprojector”I saw that same advertisement in an Ed Tech magazine. I called Dukane andsaid “What up”? The answer: “that’s not “new news”The fact is that several projector companies, including Dukane, now provide an“app” that will mirror what’s on you ipad to a projector that is connected to yourcampus internet network. Some projectors, not all, but some, can be networked.If you refer to the diagram of the 8794H-RJ above, it has a LAN( Local Area
  • 9. Network ) Adapter. Networked projectors come with software that lets someonemonitor their status( Are they on? How much lamp life is left) over the LAN, butwith the new Ipad apps, the Ipad can share info on the Projector via Wi-Fi.But we are back to the problems with the Apps that will mirror the image overWifi. The usefulness of the “projector company supplied app” will depend on howrobust you wi-fi signal is, and that will depend on how much traffic is on yourcampus network.And if you read the “fine print” you will also see some of these apps may showcertain documents, but will not mirror the whole screen.Her is my view. A direct connection works. Unless there is some reason NOT touse if, that would be my “go to “ for getting what’s on the Ipad to a projector orLCD TV.What about other “ tablets”?I have not had chance to look at the other tablets, so I cant say with any authoritythat these also work with a direct connection. It is my understanding similaradapters for the various Android tablets do exist. As I learn more I will amendthis article Airplay is a part of the Apple OS for iPhones and Ipads, and also the Mac X“Mountain Lion” software, so I am going to assume that Apple TV is an “Appleonly” solution.Note: Ipad is a trademarked product from Apple Inc.I hope this is useful information.I would love to hear from anyone who has feedback on this or ideas to share.I am confident of the ways I have outlined to connect an Ipad to a projector,because I have tried the RGB Dongle and Apple TV personally. The HDMIconnector is an option, one I have not tried myself, and should work if yourprojector has an HDMI input .I have consulted with the folks at Dukane about thefeedback they have gotten from schools and others around the country and theyhave schools using all three methods of connecting an Ipad to a data-videoprojector.
  • 10. However, if there are better ways to accomplish the same thing, I would love toknow about them.Finally, I would add that once your Ipad IS attached to a projector, there are lotsof Apps out there that do many neat things, including one I saw that turns youripad into a “virtual overhead Projector” : it has simple drawing tools and will alsolet you annotate an imported picture.Another “hot topic” is that of “ebooks”. I think ebooks have advantages but theability to share that book with a whole group , led by a teacher, also has inherentadvantages.There are hundreds of websites and blogs with lists of Ipad apps . For me toinclude them all would be outside the range of what this article is mean toaccomplish. However, once your iPad is attached to an display device such as aprojector or LCD TV , the possibilities for its use as a teacher-centered tool arevast.Bill McIntoshAuthorized Dukane ConsultantPhone: 843-442-8888Email: WKMcIntosh@Comcast.netYou can find information on all of Dukane products here is the Dukane Homepage:
