Change DPI of visualisation

[omiTD]

Well my question to you is if it is possible to reduce the DPI in AV mode?!? It´s because i plan to use it on an OEM Nav-Display of an some years older car, it already works, but ist very hard too to see the mouse and read, even if you switch it to HUGE.

ah, i use it in the PAL (576-something resolution) with the AV-connector.
...would be great if you could help or give me some tipps! :-)

Yes. I need this too! I have plans to use this box with older TV which don't have HDMI port. It seems that the box is changing resolution to 576 cvbs which is good for older TV's, but DPI is very high. Also I noticed when i start KODI, it will switch to 1920x1080 instead. So maybe we can tweak build.pro?

Try to play with ro.sf.lcd_density in your build.prop file.

i switched the ro.sf.lcd_density from 240 to 180 to 112...saved file, rebooted, nothing happend :-(
do i need to do more, or has anybody other suggestions to help us?

[dlareklami]

ro.sf.lcd_density did not helped me
However, I found another tweak on another forum, that supposed to enable cvbs mode on resolutions lower than 720p.
Add this line to your build.prop file, found it here

#Open cvbs output mode

ro.amlogic.has.CvbsOutput=true
ro.video.deinterlace.enable=false
sys.defaultStream.ismusic=true

Also, you need to add this row under: #UBOOTENV MTD NAME

ubootenv.var.cvbsmode=

I tried this tweak also, but no luck for me.

I found that maybe you need to modify. I found this information here:

[B]from[/B] ubootenv.var.cvbsmode= [B]to [/B]ubootenv.var.cvbsmode=576cvbs

I will try this a bit later.

did it work in your case?

[dlareklami]

Yes it helped me. I am happy now. Image on TV gets adjusted automatically. But sometimes I still need to choose correct ratio on TV itself. For example interface from box is set to 16:9, but on TV it is set to 4:3, so I just switch TV to 16:9. But now, I can see video/youtube normally. Interface of the box itself is still a bit blurred, colors are not clear and vivid as on 1080p displays, but I can leave with it now.
I will try another solution soon to resolve interface issues.

Is it still at normal 576 cvbs with high DPI, or did you manage to get everything displayed bigger on the Tv-Screen?

[dlareklami]

For example if I watch a movie on TV it will be at 576i cvbs mode. User interface did changed also, now it has lower DPI, it fits screen for maybe 99%, only top row is not visible. But still, sometimes not enough to read small text. I am working on it.
I was able to get normal DPI and normal screen resolution for user interface via vieomode.sh script, but it was hardcoded, i was not able to switch back to 1080p mode again.

Found that using one of resolution changers apps can solve issue easily
I used this one: https://play.google.com/store/apps/d...lution_changer
and here you need to find what resolution you need https://en.wikipedia.org/wiki/Standa...l_aspect_ratio
Now i set mine box to 1048x7576 with 150 DPI and I am totally happy now!

Cool, yes the NOMone Resolution Changer does work! But i have the Problem, that if i reduce the resolution the shown picture gehts just smaller and is shown in the left upper edge, rest of the display gets dark (doesn´t matter if i use HDMI or analog AV-out). DPI Changes work, but only inside the apps, on the Desktop (ans some parts/grafiks of some apps) still stay small so you can´t read it using AV-out/cvbs mode :-( any one ideas?
