Connecting an ipad to a projector

  1. 1. Can an Ipad be directly connected to a Data video projector?I 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. 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 the Apple Digital AV Adapter to mirror whatever’s on yourIpad or iPhone 4S screen — apps, presentations, websites, andmore — on your HDTV or HDMI-compatible display in up to 1080p HD
  3. 3. (movies play at up to 720p).Watch slideshows and movies on the big screen in up to 720p byconnecting your Ipad, iPhone 4, or iPod touch (4th generation) toan HDTV or HDMI-compatible display. The Apple Digital AV Adapterroutes digital audio to screens that support it. Connect theApple Digital AV Adapter to your Ipad, iPhone 4, iPhone 4S, oriPod touch (4th generation) via the 30-pin dock connector and toyour HDMI-compatible display using an HDMI cable (soldseparately).A second 30-pin connector built into the AV adapter lets youcharge and sync your device while it’s connected to your HDMI-compatible display.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.Also, while the most recent projectors are now including HDMI inputs, not all, particularlynot all “historic” projectors’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 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).Apple TV
  4. 4. The 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.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”.
  5. 5. 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.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.
  6. 6. 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.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:
  7. 7. 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. 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.However, there are better ways to accomplish the same thing, I would love toknow about them.Bill McIntoshAuthorized Dukane ConsultantPhone: 843-442-8888Email: WKMcIntosh@Comcast.netYou can find information on all of Dukane products here is the Dukane Homepage :
