Hi, I'm getting a very small image when streaming from Samsung DeX environment. The both screens are fullHD (1920x1080)

Hi. Couple simple questions. What app version? Can you open http://192.168.1.45:8080/stream.jpeg. This will give you a single image. Please check this image size.

Hi, Version 3.8.2 the jpg is of size 1080×2220 px stream

I've noticed that size is set to be screen resolution in regular phone mode - not Samsung DeX mode (there is just FHD).

Well, Android cast feature allow capturing only default screen. No ways to capture any other. For me it's kind of strange why it behaves so. What shows phone screen when you have a DEX on and ScreenStream is streaming?

In any way the only workaround is to set up image cropping in ScreenStream to cut 1080:2220 to 1080:1920.

And I'm curious what will be the DEX screen resolution and ScreenStream, if you select 1480:720 or 2960:1440?

The setup is Galaxy S8 connected via HDMI adapter to a FHD monitor. The phone screen is off, so I have an image only on the external screen. I can turn phone screen on but unfortunately the screen of my device is badly damaged. However it seems to be displaying the default phone view - nothing special with DeX. So it captures the DeX screen, not the phone one.

I am afraid the cropping to 1080x1920 won't give satisfying result as the effective desktop image on last stream.jpeg is 1080x607, which is low.

The DEX screen resolution can be configured independently form phone screen resolution. Phone resolution can be obraz while DEX resolution can be Screenshot_20211025-182404_Samsung DeX home the largest resolution is surely disabled due to conntected screen which is FHD. I have no bigger screen to test that option.

From my test the DEX resolution has no effect on */stream.jpg resolution. However, setting phone resolution has. The */stream.jpg resolution is the same as the phone screen resolution.

Yes. That's true. One more idea - rotate phone sheen to landscape mode. This will give stream.jpeg size 2220:1080 and crop it in app to 1920:1080.

Yeah it works!! So to get a proper fullHD stream with DeX on Galaxy S8 (and probably other ones), one need to do the following:

  1. set device screen resolution to 2220x1080
  2. get into landscape mode, by setting autorotate and opening some app (ie. SMS app). i think that home screen is always in portrait mode and cannot be in landscape
  3. get into Samsung DeX, by choosing it from notifications
  4. run ScreenStream app and in settings set crop image 150px from both left and right, which will take 300px from 2220px so we get 1920px of width :)
