Full-screen Playback With the Apple TV ”) This makes it impossible to, say, quickly look up a note by pausing the presentation without the mirrored operating system screen to be shown to your audience - assuming you use an A5+ device with, by default, enabled mirroring and with the HDMI/VGA adapters or the Apple TV on previous devices or with the composite / component cables, a black screen will be shown.

(This also applies by the Apple TV's natively playing back an embedded video in full screen – see section “ 4. If yours isn't, feel free to skip right to Section 1.2 "Any Differences Between Source Devices?”.)Īs with all other iOS apps with native TV output, Keynote also stops outputting when sent to the background by pressing the Home button. (This section is only relevant to people with jailbroken iDevices. Please consult THIS tutorial for more info.ġ.1 Playing Back Presentations In Background Your only hope is having a way of wiring up your iDevice to the TV with a connection type where overscan is automatically switched off: VGA or, if you're lucky, HDMI-to-DVI. Unfortunately, Keynote isn't an exception. Problems With Microsoft Office Files”) is devoted below.Īnother problem is Apple not making overscan optional in any of its apps. This is a MAJOR problem, to which an entire chapter (“ 2. Actually, the achievable resolution, even with the HDMI and VGA adapters, is far-far inferior to that of even the iPhone 5's mirroring mode, let alone iPads and only a little bit better than with the composite / component cables. The main disadvantage is as follows: as with many other apps in the AppStore (or in iOS itself, see for example my report on the pretty bad TV out results of the built-in Photos app and Apple's $4.99 iPhoto HERE), the TV out support isn't properly tested / debugged, resulting in major resolution problems with everything Microsoft Office-based. This is the subject of Section 1.1 below. This can only be circumvented on jailbroken iDevices – see next bullet Ĥ) On jailbroken devices, the app can even be sent in the background with the slideshow continuing – and, with Apple's own “Keynote Remote”, even remaining controllable. However, you cannot just switch to another program to quickly look up something without the audience seeing it on an A5 + (that is, by default, mirroring-enabled) iDevice or without the TV output getting black (on A4 devices, that is, where there's no OS mirroring). This means you can display the current time or even presenter notes locally, which won't be seen by your audience. (As usual, the composite/component cables are only capable of lower resolutions – 480p/576p or 480i/576i using the component/composite cables, respectively.) ģ) The TV output can be entirely different than the one on the originating iDevice's actual screen output.
#Iphone 4 keynote 720p
With A4 devices (iPad 1, iPhone 4 or iPod touch 4G), the maximal resolution is 720p (HDMI adapters) and XGA (VGA adapter). This means even an iPhone 4S, equipped with a 960圆40 screen, can output Full HD (1920x1080) when used with the HDMI or the VGA adapters.
That is, don't expect a, say, iPad 1 to be able to show a presentation wirelessly over the Apple TV – you can only used wired output with these A4-based iDevices.Ģ) The output resolution is fully independent of that of the device it's played on. B) Wireless output via the Apple TV is only supported on iDevices with A5+ CPU's but not earlier ones.
