OK techy friends, I have a mystery.

I have an Ipad that I use to watch TV and I connect it to an external monitor using an HDMI cable with an adaptor to whatever the ipad uses (I can't keep track of connector names).

ANYWAY. It only works for some streaming services and not others. Like why does it connect perfectly for apple TV and Hulu but for HBO it will play two minutes or so and then act like it's not connected to the monitor. Even weirder, Netflix used to work fine and now it doesn't. I can play Netflix on my ipad but if I hook it to the monitor, it gives up. But if I switch it immediately to Hulu, it plays on the monitor.

What is happening? Shouldn't the monitor just mirror the ipad?

oh yeah and sometimes it does exactly mirror the ipad and sometimes it doesn't show on the ipad and plays on the monitor only.

To my memory as a developer: not necessarily. It does by default, but it's up to apps to decide what to show on a second screen. (For example, in the Photos app, the second screen displays the current photo without the interface.)

That could be what's happening with some streaming apps – perhaps they deliberately display nothing on the second display – but your description also sounds like perhaps a glitch or an HDCP thing.

@Starfia @Bronwyn I do first-line tech support for Berkeley English (= flailing around a lot until something works) and I recently discovered a campus-licensed streaming service would not go from the prof's laptop to our projector, so I too have seen that situation where the service blocks it.

@jmccyoung @Starfia ok so I’m not hallucinating. It’s weird though- why wouldn’t they want me to be able to send it to a monitor? It looks better on the monitor!

@Bronwyn @jmccyoung @Starfia It may have something to do with how the various services implement High-bandwidth Copy Protection (HDCP), which causes plenty of headaches for people who aren't trying to pirate anything

@gneilyo @jmccyoung @Starfia ugh it’s so annoying. I don’t have a TV so this is how I watch things and I see no reason for them to block me since I’m paying for streaming!

@Bronwyn Out of curiosity, what's the make/model of the monitor?

@Bronwyn And is the HDMI dongle thingy made by Apple or a 3rd party?

Bronwyn Harris 1d ago

@gneilyo Samsung and third party. Think that’s the problem?

@Bronwyn I asked about the dongle because of this thread. One respondent said their inability to display on an external monitor was fixed when they switched to the official Apple connector.

I wouldn't say go spend money on a new dongle on a hunch, but it could be a factor https://discussions.apple.com/thread/256078806

@Bronwyn If you can share the model # of your Samsung we can look to see if there's an arcane setting we can try turning on (or off), or possibly there's new firmware available that might help

@gneilyo I’ll look after work!

@gneilyo Samsung S24R65OFDN monitor

@Bronwyn Thanks! I don’t see any firmware updates for that monitor on Samsung’s website. Also, since it is not an ancient monitor I doubt it’s a matter of it not supporting that HDCP protocol.

I’m leaning toward this theory https://mastodon.online/@gneilyo/116281279635849752

@gneilyo yeah seems like it which is a bummer. Thanks for looking into it!

Bronwyn Harris 1d ago

@gneilyo interesting. The weird thing is that, for example, it’s 100% functional for Hulu. So it makes me think a new one wouldn’t help, that it’s the particular streaming service.

@Bronwyn I had always thought the copy protection stuff was handled at the hardware/OS level and would be transparent to apps that run on top of it but who knows
