Second screen sodtware/Dudu is setting issue

Gwinambele

Hello
I finally managed to connect second display via USB c.
Twre are two setting right?
-casting apps for that screen
-duplicate main Dudu unit screen

When I choose first option and let's say I use Google maps.
I open maps set navi etc. And I push this icon on top to cast it on second screen.
And it's working fine.
But...
When I open Fm radio on main unit (or navradio+ in my case) it also open on second screen and setting changes for duplicate screen (not desktop as it is called in Dudu)
I have to change that option again, open Google maps again and again cast it to second screen

Basically this setting doesn't save or it is being changed by something.

Also even tho I don't unplug screen when I put Dudu to sleep mode sometimes resolution and offset settings for second screen reset after next launch from sleep.

And last thing is a little suggestion and my wish list.
Would be able to make "Task" to open some app directly on second screen?
Like we can autostart apps with ignition trigger but to put it on second screen without having to make it manually Everytime Dudu unit starts.
That would be awesome.

Hope you understand what I mean and I hope you can help me somehow.

Its also wierd but I have it plugged in via USB c and I don't touch it. And very often when I turn off and on Dudu unit it show no signal. I have unplug it and plug it again (sometimes few times) to make it work.

Most of these issues stem from substandard displays or cables. You can test this yourself by using a Type-C cable for video transmission. The cable requirements are quite high—it won't work with just any charging cable for your phone.

When I launch Dudu after some time it's working fine.
I guess it's something with usb standby. It keep power for 5 min. After that 5 min screen starts normally.
But there is still problem with screen mode. I keeps changing to clone Dudu screen and I have to switch it to desktop mode every time.

I noticed another issue.
When I cast some app to second screen and I open YouTube on main unit and I set YT video quality to anything above 480p it struggle to play. Like voice and video is not synced and video itself lag.
If I disconnect second screen everything is working fine.
And I have still problem with second screen resolution.
Sometimes when I launch Dudu unit 2nd screen starts with 1024x800 which is not OK, and sometimes with 1920x1080 which is correct.
If it start with lower resolution I have unplug it and plug again. Sometimes even few times.
Like settings in Dudu are not working.

One more thing:
When i duplicate Dudu screen on 2nd screen resolution is ok (apps are full screen with correct ratio etc)
When i cast some app (like google maps) it is not fullscreen. I see black bar at bottom. When i stretch it with sliders in Dudu settings aspect ratio is broken and touch screen is not working correct ( i have to click upper the actual button is on screen)
I realy hope you can help me somewhow.

I'm not sure what your screen resolution is.
Perhaps it's a compatibility issue with the screen. To adapt to this screen, a screen is required.

So what are this resolution settings for? It seem like it doesn't work at all since it doesn't change anything :/

Gwinambele Have you tested replacing the Type-C cable with a higher specification?

Gwinambele

I have tested all sort of cables and best result I have with Display port hub and dp to hdmi cable plus USB for touch.
But problem with resolution is still the same. Sometimes it start with low resolution and wrong aspect radio and sometimes with good one. It's kinda random to me.
Also this display mode setting also keeps changing to clone Dudu screen Everytime I cast app.
It doesn't work when I open some app directly by clicking on second screen menu.
Kinda annoying as I want to set for example navigation on big Dudu screen and switch it to 2nd scree. But then display mode change to clone.
