High DPI on uidroid

[linustorvalds]

Hi,

Is there any way to get UIDroid to display in Full/High DPI? The long-press D-Pad centre options are fairly limited and making changes to the NLite Client on the host doesn't reflect on UIDroid.

I don't have time to take photos right now, but the icon/text scaling is fairly poor for a 4K display. I'm using the app on a FireTV stick. 
I can post photos to better explain what I mean by this if need be.

I suppose my main question is
1. Is there a way to make UIDroid display in high DPI mode, similar to the desktop client
2. If not, can this be added

I don't plan on changing uidroid from 720p for the GUI but videos are shown at native resolution. Screen http transfers will be 4x slower and not worth the tradeoff IMO. My understanding is Kodi sends 720p screens too and lets the monitor upscale.

Text rendering is done by the server though and I am not sure if any of the nlite settings other than higher resolution make a difference to the source, these are not documented.

You can use adb to capture a screenshot and zip and attach it, that would be better than a photo. While you are using adb check the adb shell wm size and adb shell wm density to see what your device is running. You can modify these for your requirements.

That's fair, though the option would be nice? If the speed is network dependant anyway. 720p is fine honestly it's more just icon scaling and such.

I can't lie, I've never used ADB in my life. Can you link any kind of tutorial or resource for doing this on a Fire stick?

How did you install uidroid? https://html.duckduckgo.com/html?q=andro...tfy&kae=-1

The screen capture should tell us if the server is doing its stuff. Screenshot example here https://developer.android.com/tools/adb#screencap

I will let you search for wm size and wm density.

At the time, I pulled the .apk to my own server then used some downloader application to get it onto the stick. Didn't use adb to get it onto the stick.

I've attatched the screencaps using adb. The resolution of the caps is what the stick is set to.

This is likely more of an nlite issue (as the same thing happens on desktop) but you can see all icon scaling (not just channel logos) is done fairly poorly. Not matter what resolution, etc it scales them badly. I can live with the blurry 720p UI but icon scaling should get sorted at some point.
(This is not user error, I've played with various resolutions, used good logos, etc. Edges are rough everytime)

I don't see the attachment in the previous post...lol. Let me know if they didn't upload.

[mvallevand]

Can you zip and attach the actual file as requested. What do you mean by nlite issue?

The attatchment system is being an utter pain in the ass. Apologies.

Thanks. The problem is attachments need to be under 2MB and you included two 4K screen caps, one may have worked.

If you set your ATV to display 1080p does it look better? As noted there could be issues with your monitor upscaling. Those wm command I gave to do still apply too.

I will leave it to sub to talk about scaling and icons, the source icons won't be HD resolution which doesn't help.

You can also try changing values in <UiServerZLibLevel>2</UiServerZLibLevel> This will require restarting the server. I think 0 is uncompressed.

1080p is about the same result. I don't think it's a display scaling issue. The issue occurs on my 2K monitor with the desktop NLite and my 4K TV with the android app, so it seems to just be an issue with NLite itself and the way its handling icon scaling. The same icons with Jellyfin didn't have this issue, etc etc.  It's not a big deal its liveable, just a good quality of life upgrade I think. Makes it look a bit less dodgy

"Those wm command I gave to do still apply too." - could you post the exact commands? as a adb noob I'm not aware of what these would be. All I did was...

PHP Code:

adb shell screencap -p /sdcard/test2.png 


"the source icons won't be HD resolution which doesn't help." - true, but there is likely a much better scaling method that doesn't cause so much aliasing. An NLite issue as a whole?

"You can also try changing values in <UiServerZLibLevel>2</UiServerZLibLevel> This will require restarting the server. I think 0 is uncompressed." - I'll give this a shot at a later date and report back.
