Extra DSLR monitor on telephone

[Quentin]

Hello

I am not aware if it is possible to use the USB plug in order to get a 2nd monitor like this video

[Walter Schulz]

Is this a question or something you wanted to show and tell us?

[Quentin]

I wonder if I can use both an HDMI monitor and telephone monitor plug on USB, at the same time

With different apps you can control many DSLR cameras via Live View and use your Smartphone ore Tablet as an enlarged display, it needs special cable and the USB connection to the camera. If you want use Magic Lantern at the same time each app action produces via USB an error, turn off or block the camera. After longer time (2 years) with my tablet Nexus 7 I change to a Field monitor and this works perfect.
I use the 5D3–123 with a clear HDMI connection to my Field monitor, so only the camera display open on the HDMI monitor and gives me the same Information as the Camera display, but in Full HD 1920x1080 pic, the control of the Camera with Magic Lantern is not influenced

Thank you very much for the detailed reply.
I use an HDMI monitor successfully.
Its preferable to get an HDMI splitter rather than load the Camera with extra processing weight.

No. The resolution is far from Full HD in this mode and the same as with 113.
Actually, there is no any reason to prefer 123 firmware over 113 if you use external monitor this way.
But there are a lot of reasons to prefer 113 as mainstream of development and new features.

ok, whatever you believe it’s yours. I see with my Eyes that the Aputure Fine HD V2 Monitore gives me a Full-HD Picture (up tp 4K) on his screen out, very god Quality, check it out.
And don´t forget, there was a god reason for Canon to make the Firmware Update from 113 to 123, takes a lot Bugs out witch still existing in 113. So the Camera Basics in 123 are the better choice for me.
Also, with the new ML Experimental Crop Mode Build including 10.12 and 14 Bit Mode from 13. January 2017 there is IMO not more a so big different between tis Builds, according to A1ex.
So, for me a lot of reasons to use the 5D3-123 Build with Crop Mode especially in Nature and Bird photography and Video documentaries.

[...] Firmware Update from 113 to 123, takes a lot Bugs out witch still existing in 113.

Which ones? I haven't been able to encounter any bug present in 1.1.3, but solved in 1.2.3. The one I've found is present in both firmware versions.

On the contrary, it made things harder for ML, so a couple of features are not working at all on 1.2.3 (e.g. fast zebras), and others have limitations. CPU usage is also slightly higher on 1.2.3 (from Canon's side). Furthermore, there is a piece of code that gives corrupted frames on 1.2.3, but it has no issues on 1.1.3.

@NoCp_Albert:
MKIII LCD resolution is about 1 Megapixel - two time less, than Full HD.
When mirroring, it sends LCD screen image over HDMI. Doesn't matter, what the firmware.
Your monitor just stretch the image. It's hard to notice the difference on 7" monitor anyway.
So, no reason for 123 if you don't need "clean HDMI" and use your monitor instead of LCD.

Here about Canon Update - 5D3 113 to 123, dfort shows in the Crop mode tread the update list.
 
I am not the ML Expert in Details, my Basic it´s Photography (including Dual ISO) and sometimes I use ML for recording, sometimes I need also the f8 for Converter on EF100-400 Lens. The Crop Mode Build from April 2016 for 5D3-123 was perfect for me and others too. So, I get no reasons to go back to 113 Firmware. I try many times also the 113 build and I know everyone says this is more stable version, but the 3xcrop mode makes the different for me, also the 5x centered Crop with 10,12,14 Bit now. Thanks for that.
Of course a Street- or Weding Photographer and many others haves other priority´s.
