iPad Pro Cannot View Portrait Photos from iPad Pro in Portrait Mode on a Monitor ?

[magneeto]

Hey Guys !

Any Help here ? I have a 2018 iPad Pro an I am trying to Mirror my iPad Pro on to an External Dell Monitor and when I have a Photo on my iPad Pro in a Portrait Mode and when I rotate my iPad in a Portrait Mode and when I also turn the Dell Monitor Screen that I have, also in Portrait Mode I should be able to view my Portrait Photos from my iPad in a Portrait Mode on my Dell Monitor using Mirroring. But it is not happening the Photo on the Dell Monitor only show in Landscape mode and not in portrait Mode.

I posted this question on a Dell Forum and I go this explanation. Anyone here who has the iPad and also use it with an external monitor if someone can test and confirm this if this is possible that would be really helpful.

I got this explanation from the Dell Forum

"Physically rotating the display to portrait mode doesn't do anything. The source device, in this case your iPad, has no way of knowing that you've done that, and therefore has no way of knowing that it should adjust the video signal it's sending. Some displays have software to manage this automatically, but they then require you to have a USB connection between the display and source to provide this type of signal information and also require you to have software installed on the source device to have the source adjust its output. The iPad doesn't give you that option. The iPad outputs a consistent resolution signal, and it will adjust its presentation based on rotating the iPad between portrait and landscape, since the iPad of course knows when you've rotated the iPad itself, but it can't do anything about you rotating the display. And of course having a portrait iPad video signal shown on a display that's set up in typical landscape orientation doesn't use much of the external display's area. But to my knowledge there's no way to get an iPad to send a portrait video signal".

iPads do not play well with external monitors. It isn’t worth the trouble and eventual disappointment.

Anyone here who has a real experience and can help me know about this ? Then the general philosophical statement that iPad do not do well with external display that we all know.

I think he is trying to be nice. Rotating your ipad doesn’t change the video out or external monitors video orientation or the photographs orientation metadata which is in the pictures file. So it won’t work the way you want it to. You would have to edit/rotate the pics in photo to display the way you want them to while viewing them on your external monitor. The orientation of your ipad only changes the iPad display. AFAIK.

I did not see any point of his statement of adding any info except it being a very generic statement. Which I already knew about.

So basically go into Photos on the iPad go to edit and change it to a bizzare level of viewing on the iPad so that it looks portrait on the external display ? ?

Check these threads out. It would appear that the Dell monitor does not play well with the iPad regarding portrait mode -

And I think the answers you got on the Dell forum bear that out. The iPad simply has no handshake with the monitor regarding orientation.

 

[My Friend Harrison]

Well I wouldn’t set it to “Bizzare” I would set it to portrait or landscape, since those are your two choices, or you could get philosophical and realize the iPad doesn’t play well with external monitors and I wouldn’t try because I would be disappointed. Or you could experiment with rotating the pics on your ipad and not rely on using the iPad‘s screen rotation feature. I’m sure you could figure it out if you wanted to. Here’s a tip: the metadata in some file formats use different and multiple locations to store rotation information. As a forensic examiner I have to use different programs to rotate different sources to get them to display properly on different devices.

Does it work with other Monitors like on the LG Monitors ?

My LG does not have rotation but a portrait photo displays properly if I am mirroring the iPad display to the monitor. I just don't think the iPad supports translation into portrait mode on a rotated monitor. Here's another experience -

Will it help if I in the Photos APP on the iPad go to edit and rotate the portrait photo to Landscape so that it appears in Portrait mode on the Monitor ? Can this work ?

I was just telling you that it isn’t even worth bothering in the first place...

But it's a worthwhile discussion to have. It's not clear to me how much of this issue with external monitors lies with iPadOS and how much with developers not using support that may be in place. See this article -

Saying it's not worth bothering just stifles worthwhile investigation and discussion.

Absolutely Not ! I was just saying was there any value adding information in the generic statement that you wrote ? What was the point of what you wrote ? It Was useless !!

Hey you know that thing worked !! If I go to the photos on my iPad and change the landscape photo to further tilt going into edit it shows as a portrait photo on the Monitor ?

How was I supposed to know that you didn’t already know that?

So on the iPad, in landscape mode, the image displays as rotated 90 degrees? With the monitor rotated to portrait mode, the image displays correctly in portrait mode? Does it completely fill the screen at the top or bottom or is it centered with black bars all around it?

Yes it displays the Photo Correctly in Portrait Mode on the Monitor.

And yes it shows black bars on the top and bottom on the Monitor. It does not fill up the screen fully.

So for everybody's reference, the "solution" here when using the iPad with an external display is to manually rotate each image.

In case anybody is not aware you can rotate, flip, or do pretty much whatever to an image via app to match however one wishes to orient their monitor. I can install my monitor upside down and diagonal if I want to and still have a "correct" photo being displayed from any device.

Interestingly I stumbled upon the original discussion over at Dell as well. Sharing the link below for anybody interested.
